The early diagnosis method of Parkinson's disease

Parkinson's disease has no specific symptoms and thus is difficult to be diagnosed in time. When patients with mobility disorders can be diagnosed, the nerve cells have got irreversible damage, and the effect of drug treatment is quite limited. Researchers at the University of Würzburg and the University of Fort Worth have made significant progress in this research through recombinant mouse proteins and have succeeded in discovering that the risk of Parkinson's disease can be diagnosed by skin tests, which is earlier than the current diagnosis.

Scientists have examined the skin of patients without Parkinson's symptoms and found α-synuclein specific to Parkinson's patients in their nerve endings. This protein, which is characteristic of Parkinson's disease, is no stranger to the industry, but it is often determined in the patient's brain only after the patient has died.

Now the German scientists in the patient before the onset or in the early sick through a small five-mm skin biopsy can diagnose Parkinson's disease, so that the nerve can be destroyed before the patient can be targeted and effective treatment. By the way, Flarebio provides you with high-quality recombinant proteins and antibodies like recombinant TLR2.

This protein is identified to influence healthy immune system

Researchers have found through recombinant dog proteins that protein Myb plays a vital role in maintaining the health of our immune system and preventing the development of immune and inflammatory diseases. Preclinical studies have shown that Myb gives immune cells known as regulatory T (Treg) cells "authority" to control the intensity of immune responses. The study was published on Immunity and was led by Dr. Shelia Dias and Professor Stephen Nutt in collaboration with immunologists and bioinformatics teams at the Walter and Eliza Hall Institutes.

Dr. Dias said it was the first sign that Myb had an impact on the immune system. "For decades, Myb has been associated with the formation of multiple types of cancer," Dr. Dias said. "Our study shows that Myb is also important for the function of Treg cells, and we find that at the site where Myb is absent, the ability of Treg cells controlling immune response is also weak, and the immune system continues to respond to a range of threats from mild infections to life-threatening disease. Researchers around the world are investigating how the immune system coordinates and controls health."

"There are many different cell types in the immune system, each with a specific obligation. And when these cells fail to perform their duties, there is a risk of health," Dr. Dias said.

Professor Nutt said, "Increasing the knowledge of the mechanisms that control the immune response is critical to understand how immunization and inflammatory illness occurs and to ultimately develop more effective treatment. If we can figure out how Myb affects Treg cells in the immune system, we may be able to manipulate this activity."

"In the long run, we would like to extend this study to the clinic in order to understand whether our findings can be applied to human immunology," he said. Flarebio provides you with recombinant proteins of good quality including recombinant TLR2.

To change the direction of treatment of Alzheimer's disease

Researchers at the University of Lund, Sweden, used the latest technology to generate the formation of toxic clumps prior to β-amyloid. According to previous studies on recombinant rat proteins, β-amyloid is the root of Alzheimer's disease.

The scientific community has long believed that β-amyloid plaques are instantaneously present, and therefore the term "popcorn plaques" comes from it. However, the infrared spectrum shows the result is not the case.

"No one has used this method to observe the development of Alzheimer's disease," says Gunnar Gouras, professor of experimental neurology at Lund University. "These images tell us that progress in β-amyloid is slower than we thought and that Alzheimer's disease has a new understanding of the development process."

What does this discovery herald? Researchers use biochemical identification to see closer to Alzheimer's disease early brain changes. The results reveal another finding that β-amyloid is not a single peptide, which is linked together by four peptide units and exhibits a tetrameric form.

This finding provides a new hypothesis for the treatment of the disease - the abnormal separation of these four peptides may be the beginning of the accumulation of β -amyloid, followed by the formation of plaques. Another amyloid disease is associated with transthyretin amyloidosis, and tetrameric decomposition has been identified as the key to the development of the disease. For this disease, there is already a drug that stabilizes the tetramer, thereby stabilizing the β -amyloid protein for therapeutic purposes.

Thus, the finding can change the direction of our treatment of Alzheimer's disease. Most of the drugs are currently designed to eliminate plaques. Flarebio offers high-quality recombinant proteins like recombinant TLR2 at competitive prices.

Certain types of immune cells in tumors may increase survival

A pilot study using recombinant rat proteins and conducted by researchers at the University of Otago shows that patients with colorectal cancer having certain types of immune cells in their tumors may increase their survival. Researchers at the Department of Microbiology and Immunology have found that people with more "T-regulated" immune cells in colorectal tumors are more likely to be disease-free and have a longer life span than those with fewer of these cells.

The study involved 32 patients with earl-stage (II) colorectal cancer. These patients received more than 5 years of follow-up: 13 patients showed cancer recurrence during this period; 19 patients showed no recurrence. These findings have been published in the International Journal Cancer Immunology, Immunotherapy.

By making use of a new tool to detect tumor and immune cells in immune cells infiltrates and measuring more complex immune cells, researchers investigated which type of immune response is associated with patient survival. The researchers found that although Immunoscore was superior to the current staging in assessing patient survival, the addition of "effectally Treg" immune cells made it better to survive. Kirsten Ward-Hartstonge, co-author and doctoral scholar of the study, said, " The findings suggest that it is possible to detect the immune response of patients with colorectal cancer to estimate which patients may be suffering from cancer and therefore should be given additional treatment. This information can be used to customize existing treatment programs to target people who really need them, rather than taking more blankets."

"About a quarter of patients who are currently considered ‘low risk’ will use the current staging method to potentially develop the disease again," Miss Ward-Hartstonge said. These patients usually do not receive chemotherapy or radiotherapy because the risks and costs are considered to be more beneficial.

By detecting immune cells from individual patients and "Treg" immune cells, it may be possible to more accurately identify patients with high risk and more effective treatment. Other studies have shown that New Zealand and Australia have the highest incidence and mortality rates for colorectal cancer in the world.

The molecular mechanism of SF3B1 mutations leading to RNA splicing disorder

As a key step in the RNA processing process, the accuracy of RNA splicing is one of the prerequisites for the normal expression of a gene. The disorder of gene expression caused by RNA splicing is an important reason for the occurrence of multiple diseases. In recent years, high-throughput sequencing technology has detected a variety of splicing factor mutations in various tumor cells. These mutations have different effects on RNA splicing, leading to abnormal expression of downstream genes. SF3B1 / Hsh155 are a key factor in the early splicing assembly, and a high frequency mutation occurs in a variety of tumor cells with most significant in patients with myelodysplastic syndrome (MDS) and chronic lymphocytic leukemia (CLL). The studies through recombinant horse proteins have shown that these SF3B1 / Hsh155 mutations can lead to changes in the splicing pattern of specific genes, but its molecular mechanism of RNA splicing is not clear.

Recently, the Shanghai Institute of Plant Physiology and Ecology, Institute of Plant Physiology and Ecology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, and the Charles Query Laboratory of Einstein College of Medicine in the United States have published research papers in the International Journal of Genetics and Development, and the study is titled "SF3B1 / Hsh155 HEAT motif mutations using interaction with the spliceosomal ATPase Prp5, resulting in tangential branch site selectivity in pre-mRNA splicing". According to the high conservativeness of SF3B1 / Hsh155 protein and the advantages of the genetic system of budding yeast, it was found that these SF3B1 / Hsh155 high frequency mutants could only specifically change the accuracy of splice recognition of intron frontal region sequences. The accuracy of the identification of other areas of the child is not affected. This feature is very similar to the mutant phenotype of RNA helicase Prp5, which has been studied by Xu Yongzhen team for a long time.

The results of protein interaction showed that SF3B1 / Hsh155 had a direct interaction with Prp5. Further studies showed that the high frequency mutation of SF3B1 / Hsh155 significantly changed the intensity of its interaction with Prp5. It is important that the change in the intensity of this interaction is closely related to the recognition accuracy of the intron fulcrum region. Subsequent mutant studies have shown that enhancing the interaction of SF3B1 / Hsh155-Prp5 facilitates the formation of early splice complexes and accelerates the dissociation of Prp5. Conversely, weakening the interaction between SF3B1 and Hsh155-Prp5 will prevent early splice complex and inhibit the dissociation of Prp5. This progress not only reveals the molecular mechanism of SF3B1 / Hsh155 high frequency mutation leading to RNA splicing disorder and improved the assembly model of early splicing body, but also provided important clues for the further study of related diseases.

Methylation deficiencies can be important causes of cancer

Every human cell contains a complete DNA gene that contains not only the genetic information of the human body, and the so-called methyl group in the gene is an essential component of human tissue. Researchers at the Jena Institute of Aging in Germany have confirmed for the first time that DNA errors and methylation deficiencies are an important cause of cancer. The results of the study were published in the latest issue of Nature which also publishes other studies on recombinant rat proteins.

Each tissue of the human body consists of tissue-specific cells of a particular attribute. Gene selection is very strict, such as in the intestinal cells only the corresponding gene directory activation into intestinal cells. What plays an important role in gene regulation is the so-called methyl group, which activates the gene by the action of the enzyme, and the process is called DNA methylation. When the human body develops cancer or suffer from aging diseases, the activity of normal gene fragments will be wrong. The exact process and the role of DNA methylation have not been fully studied.

The function of DNA methylation as a gene to start the "switch" (promoter) has been known, but why a single gene has methyl groups (the so-called gene body) is unclear so far. The team led by Francis Nari at the Leibniz Institute for Human Aging for the first time confirmed that the gene would go wrong when the promoter in the gene contained methyl groups. The result is the generation of abnormal proteins that interfere with the composition of normal cells, causing cell function and identity to undergo large-scale destruction, cell variation and may lead to cancer, which is a mysterious process of DNA methylation.

"The results of this study are exciting because we are now finally able to understand why many of the DNA in cancer cells is rarely methylated," Dr. Francis Nari says in a research note. "It is a lack of genes that cause the gene to be abnormal active state, producing abnormal proteins and spreading cancer cells." Unlike the natural degeneration in the DNA life cycle, changes in DNA methylation deletions can in principle be regulated by so-called chemical messenger substances. Dr. Francis Nari added, "There is no DNA methylation in the genome, and there may be a protein mutation, which is a completely new understanding and will provide a new way to treat cancer. If we find a way to make a methyl group transfer to the exposed cancer cell DNA sequence, it is possible to prevent cancer cells from breeding."

A convincing scientific evidence for the Zika virus leading to microcephaly

In recent years, Brazil and other countries in the Americas frequently show microcephaly. According to studies on recombinant human proteins, the scientific community has confirmed that the Zika virus infection shows some association with the incidence of microcephaly, but they don't know how the virus impacts fetal brain development. German researchers have said that they have found the scientific evidence of Zika virus that causes microcephaly.

Researchers at the University of Cologne, Germany, and other institutions reported in a new issue of Cell-Stem Cells that they "reprogrammed" healthy human skin cells into cultured pluripotent stem cells to culture neural precursor cells. Neural precursor cells can differentiate a variety of nerve cells and can be described as the "starting point" of brain development.

Under specific experimental conditions, the researchers gathered many neural precursor cells into brain organs, that is, a few millimeters in size with three-dimensional structure of the brain tissue fragments. The process of embryonic brain simulates the early development and observes the virus effect of infection on embryonic brain development.

The results showed that Zika virus allows cells to involve in cell division - the central body shows failure so that nerve precursor cells prematurely differentiate into mature nerve cells. This "precocious" seems to be of no harm, but it will make a lot of nerve precursor cells no longer involve in brain organ growth into a complete brain process, leading to microcephaly.

Researchers said that they used Zika virus strains isolated from the small head deformed embryos in the experiment, and the experimental results provide a convincing scientific evidence for the Zika virus leading to microcephaly.

Zika virus spreads mainly through Aedes aegypti, but it is also sexually transmitted. People infected with Zika virus may show fever, rash, joint pain and other symptoms similar to dengue fever. The vast majority of infected patients are mild, but pregnant women need to be careful. Once infected, it may lead to fetal malformations.

A new development in CRISPR has been made by the father of gene editing

The father of gene editing Zhang Feng made a new development in CRISPR, and his research team identified two class II CRISPR-Cas systems (subtype VI-B) that lack Cas1 and Cas2 through recombinant rat proteins, which contain a single large effector, Cas13b and two previously-unidentified related proteins: Csx27 and Csx28.

The microbial adaptive immune system CRISPR-Cas (regular intervals of short palindromic repeat and CRISPR-related proteins) helps bacteria and archaea resist exogenous nucleic acid invasion. CRISPR-Cas system is divided into two categories: Category 1 CRISPR-Cas system is the use of a variety of Cas protein and crRNA to form a complex; 2 type CRISPR-Cas system is a large single component of the Cas protein co-crRNA.

Scientists studied the most highly-conserved cas genes involved in the CRISPR immunization phase and analyzed the microbial genome sequences of their loci and carried out a diversified CRISPR-Cas system to calculate the sequence database. Using this method, a class 2 subtype VI-A system targeting the RNA of Cas13a (formerly C2c2) was found.

In this study, Zhang Feng team used the computer database mining method and found two subtypes VI-B CRISPR-Cas system which can achieve heterologous expression of RNA interference. Cas13b treats its own CRISPR array with short or long repeats, excising the target RNA with ribonuclease activity. In addition, they also analyzed the RNA secondary structure required for the target. The discovery of these systems has helped to develop new tools for manipulating and monitoring cellular transcription processes.

The results of this study have been published in the journal Molecular Cell on February 16, and Zhang Feng is the author of this article. Zhang Feng is one of the pioneers of genomic editing technology CRISPR and has played a key role in applying the CRISPR / Cas system to human cells. In recent years, he has won many awards and has been called as "the father of gene editing" by the media.

Researchers have discovered the potential target of early-stage Parkinson's disease

The team led by Patrik Verstreken (VIB-KU Leuven) has identified the underlying mechanisms of early Parkinson's disease. Making use of flies, mice and patient cell models, the team focused on cardiolipin which is combined by glycerol C1 and C3 and two molecules of phosphatidic acid and is an important component of mitochondrial inner membrane and bacterial membrane. They demonstrated that reducing the role of protein FASN which affects mitochondria can lead to an increase in cardiolipin levels and a decrease in Parkinson's symptoms. These results may pave the way for the treatment of lipid-based Parkinson's disease. The team's research was published in the Journal of Cell Biology with other articles on recombinant mouse proteins.

In this study, Verstreken and his team of collaborators from Belgium, Germany and Portugal observed the protein FASN responsible for lipid generation in cells, bypassing the genetic defects of mitochondria. "Several drugs that block FASN are already present because this protein is important for cancer research and treatment, and many drugs have been used in clinical trials. Through this study, we can now have the background of Parkinson's," said Professor Verstreken.

In their research process, the researchers encountered an unexpected phenomenon. Using flies, mice and human cell models, they saw that FASN has a direct effect on mitochondria. Mitochondria have their own independent genome and acts as an energy generating machine in their cells.

"The PINK1 gene encodes the PINK1 protein, and one of the mutations leads to lower levels of mitochondria in the mitochondria," said Professor Verstreken. "Surprisingly, blocking FASN, which is not limited to mitochondria, actually avoids the PINK1 mutant mitochondria effect, thus blocking FASN increases the amount of specific type of lipid in the mitochondria and reduces the degradation of neurons.

Professor Verstreken has identified several goals for future research projects seeking a deeper understanding of the linkages between specific levels of lipid in neurons and Parkinson's disease. "Before developing new treatments, we need to answer questions such as "whether there is a link between early Parkinson's prevalence and progress and lipid content, "Professor Verstreken said. “Although we have successfully demonstrated that cardiolipin can improve the function of mitochondria in flies, mouse models and human cells, we still need to explore its effect on actual patients." By the way, Flarebio provides you with high-quality recombinant proteins including recombinant TLR2 for your research.

Many autoimmune diseases have common susceptibility genes

Shanghai Jiaotong University School of Medicine was informed that Shen Nan research team from its affiliated Yan Chai Hospital collaborated with the United States South Carolina Medical University and other institutions to find susceptibility genes associated with a variety of autoimmune diseases, finding new targets for the intervention treatment of systemic lupus erythematosus, rheumatoid arthritis, primary Sjogren's syndrome and other autoimmune diseases. Related results have been published online in the journal Natural – Genetics, which also publishes other studies on recombinant human proteins.

To carry out the mechanism research on autoimmune diseases from the gene level and then to find an effective target for intervention has been the focus of the study in recent years for Chinese and foreign rheumatoid immunologists. Shen Nan research team joint includes the Chinese Academy of Sciences Shanghai Institute of Health Sciences Institute of Health Science, Peking University People's Hospital, Nanjing Medical University, South Carolina Medical University and other research units. They made use of immune chip and found a significant susceptibility site which is significantly related to systemic lupus erythematosus. Since this site is located in the genomic noncoding region, gene expression correlation analysis suggests that this locus is not a functional site. However, the site is located near the complex region of the repeatable multi-copy region and can't be used to find a functional site of disease linked to this site using high-throughput second-generation sequencing (NGS). Thus, the researchers are never able to lock the pathogenesis of intervention, nor are they able to study the function change mechanism of pathogenic sites.

The researchers used a specific long fragment gene amplification sequencing method in the complex gene region and found another functional genetic susceptibility site. The mutation type of susceptibility this site would cause NCF1 protein amino acid changes, resulting in the reduction of NAPDH oxidase reactive oxygen production, thus participating in the development of the disease.

"More importantly, the site is also associated with the genetic susceptibility of patients with rheumatoid arthritis and primary Sjogren's syndrome," said Shen Nan. In the research method, this study used the first generation of sequencing method to find functional pathogenesis site, making up for the second generation of sequencing technology loopholes and providing a new way of thinking for the future discovery of functional pathogenic multi-gene complex genetic diseases.

To study protein dynamics in a new way

Researchers have developed the first computational method based on evolutionary principles to predict protein dynamics. These researchers are from the Structural Biology Computational Group of the Spanish National Cancer Research Centre (CNIO), led by Alfonso Valencia, together with a group led by Francesco Gervasio at the University College London (UK). Protein dynamics can explain the changes in the shape or dimensional structure that they experience in order to interact with other compounds or speed up chemical reactions. This study push the development of the computational study of protein dynamics, and it is helpful for the design of drugs and for the research about genetic disease. It is published in the journal Proceedings of the National Academy of Sciences (PNAS), which also publishes other studies on recombinant dog proteins.

As we know, proteins are crucial to the thousands of cellular functions which work in a living organism. It is chains of smaller molecules which are called amino acids that form the protein - a three-dimensional structure. By studying the co-evolution of amino acids, we can reconstruct the form or structure of these biological compounds in their natural surroundings. We can also predict physical contacts between amino acids with higher accuracy and in sufficient number by analyzing the sequences of a given family of proteins, to reconstruct the folding and structure of a protein accurately.

Nevertheless, the structure won't remain changeless. It interacts with other biological compounds or with drugs, which is called protein dynamics. The study about it turns out to be extremely difficult no matter through experimental observations or computational tools.

"We developed a model in which the amino acids that have a strong co-evolutionary relationship attracted each other, without further additional data," says Simone Marsili, researcher who has also participated in the project. "First, we simulate the folding process and then we can see how the simulations were able to predict the changes in shape of the proteins at different levels of complexity, including those required for kinases to function."

Squalamine can improve the treatment of Parkinson's disease

Scientists report that a compound which occurrs naturally blocks the molecular processes of Parkinson's disease and inhibits its toxic products. The study was completed using recombinant rat proteins by the University of Cambridge and the United States National Institutes of Health and other academic centers in Europe and America.

In the new study, the researchers conducted a series of experiments on the interaction between squalamine, α-synuclein and lipid vesicles. They found that squalamine inhibits protein aggregation by competing for binding sites on the surface of vesicles. By displacing the protein in this manner, it significantly reduces the rate of toxic particle formation. Further tests conducted in human nerve cells show that squalamine inhibits the toxicity of these particles.

Finally, the team tested the effect of squalamine in animal models of Parkinson's disease and used nematodes to express the α-synuclein gene in muscle cells. When the nematode develops, the α-synuclein gene prevents them from moving and the ingestion of salicylamine from the mouth can prevent such paralysis. All the results show that squalamine can be used as a basis for at least some of the symptoms of Parkinson's disease. Researchers said they are planning to conduct clinical trials on Parkinson's patients in the United States.

However, there are further studies to be confirmed, such as the exact benefits of squalamine and drugs may lead to any results. In particular, it is unclear whether squalamine can reach the brain-specific regions of the major molecular processes responsible for Parkinson's disease.

The researchers believe that the initiation of the investigation of salmianol to relieve other symptoms of the effect will be very interesting. By targeting the gastrointestinal system and influencing α-synuclein in the gut, the compound may alleviate severe constipation experienced by the patient. So this treatment can lead to other parts of the body cascade signal, at least in the peripheral nervous system relieve Parkinson's disease. Parkinson's disease has many symptoms. The researchers hope that this compound or its derivatives have a similar mechanism of action to alleviate some of these symptoms and to improve the patient's life at least.

To revolutionize the treatment of metastatic uveal melanoma

New research at the University of Liverpool has identified the role of specific proteins in the human body and found that they can help to prevent eye cancer by initiating cancer "cell suicide". The new findings obtained through recombinant dog proteins may help to revolutionize the treatment of metastatic uveal melanoma (UM) - a disease caused by pigment cells (melanocytes) in eyes - and there is currently no effective treatment.

Metastasis is that cancer or other diseases spread from one part of an organ or the body to another, rather than the part directly connected to it. This is the case in about half of all UM patients. Although rare, UM is the most common primary eye cancer in adults. Although primary tumors can usually be treated very effectively, as many as 50% of patients have metastases in the liver, and there is no effective treatment for such metastases.

Dr. Luminita Paraoan from the Department of Ophthalmology and Visual Science at the Institute of Gerontology and Chronic Disease, University of New York, published a new study in the British Journal of Cancer that identified the role of a protein called p63 in UM. Chromosome 3 is one of 23 human chromosomes. People usually have a pair of chromosomes. A portion of chromosome 3 contains the gene of protein p63. Unfortunately, people with aggressive (anti-apoptotic) cells do not have this part, so there is no p63 protein.

Dr. Paraoan found that if the p63 gene is used in combination with another gene called p53, it can effectively target UM and induce cancer cells to undergo apoptosis. The p53 gene is a class of genes from a so-called tumor suppressor gene that is mutated in cancer cases. Tumor suppressor genes are protective genes. Typically, they limit cell growth by monitoring cell division into new cells, repairing damaged DNA and controlling the rate of cell death.

When a tumor suppressor gene is mutated, for example in a cancer case, the cell grows uncontrollably and may eventually form a mass called a tumor. Thus, p53 itself is ineffective in activating apoptosis in UM. "This study highlights for the first time the condition that p63 triggers apoptosis in UM," said Dr. Luminita. "Our results have broad implications for other escape cell-mediated conditions or cancer, and we hope to demonstrate a benefit to the treatment of cancers which have resistance to current chemotherapy and radiotherapy."

How does inheritance hearing loss happen?

Japanese researchers have used an inducible pluripotent stem cell (ips cell) from a patient with hereditary hearing loss and recombinant human proteins to develop inner ear cells and compared them with healthy human inner ear cells, finding the pathogenesis of this disease. This study is also expected to be used to find other treatment of hearing impairment.

Goitre - deafness syndrome is a rare congenital thyroid hormone organic synthesis disorders. It is an autosomal recessive inheritance with goiter and sensorineural deafness as the main clinical symptoms. Patients tend to develop hearing impairment from an early age and may have a language delay. The abnormalities of genes which control and synthesize protein Pendrin are considered to be pathogenic, but the specific pathogenesis is unclear.

Researchers at Keio University and other institutions used patients' blood to produce ips cells, and then they were induced and differentiated into inner ear cells. The researchers compared the inner ear cells differentiated from healthy ips cells. The researchers found that the Pendrin proteins in the inner ear cells differentiated from ips cells showed abnormal agglutination. The cells are easy to die, which is similar to the pathogenesis of Alzheimer's disease.

Ips cells are stem cells transformed by somatic cells through induced factors after treatment, having the possibility of developing into a variety of tissue cells.

Researchers in the cell experiments also found that an immunosuppressive agent sirolimus can effectively inhibit the inner ear cell death. In addition, the use of ips cell culture in patients with inner ear cells are also expected to find other treatments for hearing impairment, and the researchers prepared to conduct further research on this.

optoDroplet provides new hopes for the treatment of protein-related diseases

In a study published in the December 29 issue of Cell, Professor Brangwynne of Princeton University developed a new tool called optoDroplet through recombinant proteins including recombinant horse proteins. This tool can analyze the physical and chemical changes in the self-assembly of membranous organelles and provide new hopes for the development and treatment of protein-related diseases by controlling the aggregation and dissolution of proteins.

The OptoDroplet is a technique that relies on photogenetics to change the behavior of proteins by exposure to light. The major component of the cell is water, and therefore it is substantially transparent. Researchers have shown that they can induce phase transitions by activating photoactivators and produce membraneless organelles. At the same time, they can simply turn off the lights to cancel the process. Increasing light intensity and protein concentration allowed the researchers to further control transformation. By altering these factors, they can determine when to form condensed liquid proteins, as well as solid-like protein aggregates that may be associated with the disease.

Using mouse and human cells, the research team spliced genes from the Arabidopsis light-sensitive protein, and blue exposure will lead to self-assembly of the protein. Proteins fused with a light-sensitive label are thought to drive phase transitions in living cells. The researchers found that they can light the protein to induce aggregation, mimicking naturally occurring in the cell condensation process. The team repeatedly made the protein to condense and then dissolve by turning on and off light. Even after many cycles, this process proved completely reversible. However, with high-intensity light or high concentrations of protein, the researchers created a semi-solid gel. These gels were initially reversible, but over time they solidified to form irreversible bulk agglomerates, similar to those found in some diseases.

An example is a protein called FUS. FUS protein is essential for cells: it helps to produce other proteins and repair damaged DNA. But a large number of mutations may make FUS protein become too sticky, leading to amyotrophic lateral sclerosis (ALS). This is a progressive and fatal neurodegenerative disorder in which the patient loses the ability to autonomously control his or her muscles and protein aggregates accumulate in nerve cells of ALS patients. These clumps may originate from the pathological aggregation of FUS or other proteins, rather than being maintained as a dynamic fluid. Huntington‘s disease and Alzheimer’s disease are also associated with protein clumps blocking cells, again demonstrating that abnormal phase transitions in cells are closely related to these protein concentrations and light intensities.

Professor Brangwynne looks forward to continuing to experiment with optoDroplet to better understand the complex behavior of cells. He also hopes that these insights will not only reveal how healthy cells work but also reveal how they are pathogenic and may ultimately cure the disease.

The supplementation of folic acid can reduce the risk of chronic kidney disease

Through research using recombinant human proteins, Professor Hou Fanfan and Professor Xu Xin at Southern Medical University recently published a study in the Journal of Internal Medicine to first confirm that adequate supplementation of folic acid can significantly slow down the process of renal disease in patients with hypertension and reduce the risk of chronic kidney disease developing to uremia. Folic acid is cheap and easy to take and very safe, and it is suitable for high-risk groups as a means of prevention and treatment.

Chronic kidney disease has become a public health problem affecting 120 million people in China. Uremic patients can only rely on life-long dialysis or renal transplantation to survive, consuming huge medical resources. Chronic kidney disease patients also have a high risk of concurrent stroke and other cardiovascular and cerebrovascular events. Therefore, how to effectively delay the progress of chronic kidney disease and to prevent cardiovascular and cerebrovascular events have been the medical profession and the medical and health sector focus.

The study recruited more than 15,000 adult hypertensive patients from China's 20 rural communities to participate in the Chinese stroke primary prevention trial with an average age of 60 years. Patients were randomized to depressurization plus folic acid supplementation (10 mg of enalapril per day and 10 mg of enalapril per day) with an average duration of treatment of 4.4 year. The results showed that supplementation with folic acid significantly reduced the rate of renal dysfunction in hypertensive patients and reduced the risk of developing renal disease by 21% compared with antihypertensive therapy alone. In 1,671 patients with CKD prior to treatment, supplementation with folic acid reduced the risk of developing kidney disease by 56% and significantly reduced the risk of rapid renal impairment and the development and mortality of kidney disease.

It is understood that the lack of folic acid is very common in China, the average serum level was significantly lower than the Western population, which may be related to eating habits and genetic. In view of the importance of folic acid to human health, the United States and Canada have begun to add in cereals such as flour folic acid since 1998. China has not yet implemented a supplementary public health policy of folic acid, folic acid deficiency may also be a common cause of our population.

Epidemiological studies conducted early in the study showed that folic acid deficiency is a risk factor for the development of renal disease in Chinese rural communities. In response to this feature, the team conducted the above-mentioned folic acid supplementation delayed renal dysfunction in a randomized controlled study. The study also confirmed that supplementation of folic acid can effectively reduce the risk of stroke in patients with primary hypertension.

Aspirin indirectly inhibits the cancer proteins responsible for malignant cells

This study conducted by the University of Oregon Health Sciences (OHSU) and Oregon State University (OSU) was published in the AJP Cell Physiology Journal, which also publishes other studies on recombinant horse proteins. "The benefits of aspirin may be due to its effect on blood cells called platelets, rather than acting directly on tumor cells," said senior author Owen McCarty, a professor of OHSU's Department of Biomedical Engineering.

Platelets are tiny blood cells that help the body form clots to stop bleeding if necessary. It seems that platelets also increase the level of certain proteins that can support cancer cells and help them spread. This "oncoprotein" is referred to as c-MYC. The biological function of c-MYC is to regulate more than 15% of human gene expression. C-MYC regulators control cell life and death cycle, protein synthesis and cell metabolism. However, studies have shown that in cancer, the oncogene is overexpressed.

The researchers of the new study explain that aspirin reduces the ability of platelets to increase c-MYC oncoprotein levels. "Our work suggests that some of the anti-cancer effects of aspirin may be as follows: during blood transport, circulating tumor cells interact with platelets that stimulate tumor cells to survive by activating oncogenes such as c-MYC." Aspirin reduces platelet and tumor cell between the signals, thereby indirectly reducing the tumor cell growth.

Craig Williams, a professor at the OSU / OHSU School of Pharmacy and a co-author of the study, further explained this process. "Early cancer cells live in a very hostile environment where the immune system attacks regularly and tries to eliminate them," he said. "Platelets can protect and help to metastasize those early cancer cells." Suppression of aspirin appears to interfere with this process.

This is the first study showing the ability of platelets to modulate the expression of c-MYC in cancer cells. The researchers noted that nearly one third of colon cancer patients and 42% of pancreatic cancer patients show c-MYC oncoprotein overexpression. They also pointed out that aspirin has the same effect on platelets at both high and low doses. As a result, clinicians can weigh the risks and benefits of aspirin intake and reduce the risk of bleeding, which is a common side effect of taking too much aspirin. The authors underscored the key role of physicians and health care professionals in considering low-dose aspirin intake.

"Because the interaction between platelets and cancer cells occurs at an early stage, the use of antiplatelet doses of aspirin may be a safe and effective prophylaxis," the authors conclude. Flarebio provides superior recombinant proteins such as recombinant TLR2 for your research.

Scientists are trying to prevent transfer of cancer by blocking their energy source

According to research using recombinant rat proteins, scientists have found that cancer cells in cancer-bearing mice have a weakness - they need fat to make fuel. A team has found that blocking these cells to absorb fat can prevent the transfer of cancer in mice. They hope the same thing can happen on humans.

Now a new study adds strong evidence to this hypothesis. The researchers found that the energy sources of cells which are responsible for the spread of oral cancer in mice are fatty acids, including palmitic acid - a common food additive which is the main component of palm oil. They found that in many metastatic cells, a receptor protein called CD36 was expressed at a higher level, which helps the cells absorb fat. The high expression of CD36 is also associated with poor treatment outcomes in cancer patients, so the team decided to look at what would happen when the receptor is blocked. Incredibly, when the expression of CD36 in cancer cells is blocked, it can completely prevent the spread of human cancer in mice, but it did not prevent the formation of tumors.

"We hypothesized that the cells responsible for proliferation depend on a particular fatty acid and that they don't work without these fatty acids," Salvador Aznar Benitah, research leader, said, "But we don't yet know why CD36 would have prevented this effect."

The research team has a lot of work to do, and the current results show that this method can play a role when the cancer spreads. Inhibition of CD36 expression in mice reduced tumor diffusion by 15% and reduced tumor size by 80%. The study also found that mice with a high-fat diet made their lymph nodes and lung tumors bigger than the normal diet, which is a signal of tumor spread. What should be clarified is that this study only works for human cancer cells in mice, and it doesn't mean that the same method is also effective for humans.

At this stage, no one would suggest reducing fat intake in food to avoid the spread of cancer, especially for cancer patients who need high-energy diet to maintain health. The team is currently working on the development of human antibodies against CD36, hoping to carry out clinical trials in next 5 years.

"This is an exciting and very important first step," said Benitah, "And we have identified the cells responsible for metastatic cancer, which will be studied in more detail later. It opens up a new anti-metastatic therapy. We look forward to the end result of this study, because we have had many revolutionary new therapies for cancer treatment, but preventing its spread is unprecedented for the first time."

Scientists have found that Piezo2 protein prevents lung hyperproliferation in mice

Scientists have found through recombinant human proteins that Piezo2 protein prevents lung hyperproliferation in mice, according to a paper published online recently in the journal Nature. The findings will provide new insights into a number of respiratory disorders, such as sleep apnea and chronic obstructive pulmonary disease.

Most mammals prevent hyperproliferation of the lungs by a reaction known as the "He-Baum II reflex", which causes the inspiration to stop immediately. However, its specific working mechanism is not clear. Previously, no Piezo2 proteins were found associated with the respiratory system.

At this time, scientist Adam Patapatinian and his colleagues at the United States Scripps Institute explore the Piezo2 protein in regulating the role of lung expansion in mice. They found that deletion of the Piezo2 protein in adult mouse-specific neurons compromised the "He-Baum II reflex", resulting in increased tidal volume (i.e., greater intubation than usual), whereas neonatal mice lacking Piezo2 protein will die at birth.

These results show that Piezo2 protein can sense airway dilation, establish respiration in neonatal mice and regulate normal breathing in adult mice. This is essential for the initial expansion of the lung at birth.

The authors suggest that if the body of this expansion of the receptors defects, it will cause some respiratory disorder-related diseases, such as chronic obstructive pulmonary disease and sudden infant death syndrome. However, more detailed role of Piezo2 protein and the mechanism still needs further study. Flarebio offers good-quality recombinant proteins like recombinant TLR2 at competitive prices.

New drug has been developed to treat lung cancer

According to a new study presented at the European Society for Clinical Oncology in Copenhagen, through research using recombinant horse proteins, researchers have developed a novel antibody that boosts the immune system against tumor cells. In patients with non-small cell lung cancer (NSCLC), it is more effective than conventional chemotherapy.

In Phase III clinical trials, patients who were not previously treated took the drug called pemumab and showed more frequent efficacy and longer lifespan. After 10 months, they developed a disease progression compared to receiving chemotherapy of the patients less. More specifically, compared with chemotherapy alone, the drug reduced the likelihood of cancer progression by half and reduced overall mortality by 40%.

The effect of this new drug is so good that scientists can't believe that they simply suspend the clinical trials so that all patients are replaced by this drug. Their clinical findings have been published in the New England Journal of Medicine. "Be mindful of this day. This is a new era of lung cancer treatment," researcher Stefan Zimmermann said in an interview in Lausanne, Switzerland.

Pemumab, developed by Merck, has been approved by the FDA as a second-line treatment for patients with advanced head and neck cancer, but its first-line treatment has not been confirmed. In an early clinical trial, a similar drug called naduzumab did not achieve the desired results, and the results showed that it was not more effective in the treatment of lung cancer than chemotherapy.

But the new clinical trial is specifically for NSCLC patients. Most cancer cells in these patients contain a protein called PD-L1 that prevents white blood cells from unnecessarily killing healthy cells, but also helps the cancer cells to be destroyed. According to the research team, about a quarter of NSCLC patients with advanced disease are consistent with this description.

Compared to traditional methods of care, pumu monoclonal antibody reduced the mortality of these patients by 40% in the experiment. In another small clinical trial, the researchers found that if combined paimuomab with chemotherapy, the effect is even more significant.
