Gene Lr67 identified to resist important wheat diseases

Food problems always draw attention of the whole world. The foremost one is absolutely the grain yield which is often affected by crop diseases. Good news is that researchers have identified a gene that can prevent some of the most important wheat diseases. It is estimated that this finding can save more than a billion dollars in lost production in Australia alon every year. Through the global collaboration among the University of Sydney Plant Breeding Institude (PBI), the CSIRO, CIMMYT (Mexico), University of Newcastle, Chinese Academy of Sciences and the Norwegian University of Life Sciences, the gene Lr67 has been identified to resist 3 of the most important wheat rust diseases and another siginificant disease in Norway, powdery mildew. It is predicted that wheat will provide a fifth of global caloric intake and set to spike in the next 50 years. This study published in Nature Genetics will benefit much to wheat harvest. There is more work to be done about this Lr67 gene. More research will be conducted to study its working performance.

Researchers: Stem cell line developed to avoid risk of forming tumors

As we know that hPSC, short for Human pluripotent stem cells, can become any type of cell in the adult body, which offers great potential disease modeling, drug discovery and creating replacement cells for conditions ranging from cardiovascular to Alzheimer's disease. However, there is a risk of this: the possibility that transplanted hPSCs might also develop as unwanted tumors. Recently researchers from University of California, San Diego School of Medicine describe in their new-published study in the online journal eLIFE that a new "progenitor cell" is capable of unlimited expansion and differentiation into mature kidney cells, and without the risk of forming tumors. It pushes the advances in tissue engineering and complements the goal of rebuilding or recreating functional organs. The researchers engineered an invitro microenvironment permitting homogenous expansion of hPSC progenitor cells from the mesoderm. It is one of the three primary germ layers in early embryonic development. A germ layer forms during embryogenesis. Progenitor cells are early descendants of stem cells with more limited differentiation capacity. The researchers got the results from analyses that these newly created "mesoderm progenitors" lacked tumor-forming potential, but can differentiate into specific kinds of tissue like the cells that comprise the adult kidney. This therapeutic application will be realized in a few years and show its value to the pharmaceutical industry. Extended reading here>>>http://www.cusabio.com/Clone/lmo1075-1089566.html

Introduction to gene expression profiling tool

Gene expression profiling is a powerful tool for pathogenetic studies of complex diseases. To remedy the defect of traditional single gene expression analysis, various genehttp://www.cusabio.com/catalog-13-1.html set expression analysis (GSEA) approaches were proposed and sucessfully applied in the microarray studies of complex diseases. GSEA is able to identify diseases relevant biological pathways that are difficult to be detected using single gene expression analysis. Because of simultaneously considering the expression levels and biological effects of multiple functionally related genes, GSEA is powerful and has the potential to provide additional insight into the pathogenesis of complex diseases. Expression quantitative trait loci (eQTLs) are genomic polymorphism loci (for instance SNPs), which can regulate gene expression levels. Through genome-wide detecting associations between gene transcript abundance and genomic polymorphisms, a large number of eQTLs has been identified in human genome. Given the significant impact of eQTLs on gene expression profiles, it is interesting to conduct joint pathway analysis of microarray and eQTLs data. Furthermore, it is well known that microarray studies suffered from the impact of confounding factors, such asenvironmental and technical factors, causing unreliable feature selection and high false negative rates. Jointly analyzing microarray and eQTLs data may help to reduce bias in micorarray data and increase statistical power. However, to the best of our knowledge, few efforts have been paied for implementing joint pathway analysis of micorarray and eQTLs datahttp://www.cusabio.com/catalog-13-1.html. Kashin-Beck disease (KBD) is a serious osteoarthropathia, affecting more than 2.5 million people in China. Excessive chondrocyte apoptosis is one of the primary cartilage damage of KBD. Although extensive studies had been conducted in the past decades, the pathogenesis of excessive chondrocyte apoptosis of KBD remains unclear, resulting in the lack of effective treatments for KBD now. For instance, the prevalence of KBD in children reached 50.43% and 32.93% at the prevalent areas of Tibet and Shaanxi province of China. We recently conducted a microarray study of KBD and identified a set of abnormally expressed genes in KBD articular cartilage. 1,717 Han Chinese subjects were also genotyped using Affymetrix Genome Wide Human SNP Array 6.0. Affymetrix Genome Wide Human SNP Array 6.0 contains more than 906,600 SNPs probes, which provide genome-wide eQTLs data of KBD for this study. To improve the performance of pathway-based gene expression profile studies, we proposed an eQTL-weighted pathway expression analysis (EPEA) approach in this study. Using the genome-wide microarray and eQTLs data of KBD, EPEA was performed to identify KBD relevant biological pathways. A program EPEA developed by C and R languages was also provided for joint pathway analysis of genome-wide microarray and eQTLs data.

QTLs weighted gene expression profiling: a trans-omics pathway expression analysis of Kashin-Beck disease

Pathway expression analysis is a powerful tool for pathogenetic studies of complex diseaseshttp://www.cusabio.com/. Kashin-Beck disease (KBD) is a serious osteoarthropathia, mainly characterized by excessive chondrocyte necrosis and apoptosis. To improve the performance of pathway expression analysis, we proposed a trans-omics expression quantitative trait loci (eQTLs) -weighted pathway expression analysis (EPEA) approach for trans-omics joint analysis of genome-wide microarray and eQTLs data. In EPEA, expression quantitative trait loci (eQTLs)-weighted Kolmogorov–Smirnov-like running sum statistic was applied for pathway enrichment analysis. Permutations are used to evaluate the significance of statistics. Using the real genome-wide microarray and eQTLs data of KBD, EPEA identified 4 apoptosis-related pathways significantly associated with KBD, including SA_PROGRAMMED_CELL_DEATH (P value = 3.7×10-3), BIOCARTA_MITOCHONDRIA_PATHWAY (P value = 4.4×10-3), REACTOME_INTRINSIC_PATHWAY_FOR_APOPTOSIS (P value = 6.4×10-3), ST_FAS_ SIGNALING_PATHWAY (P value = 8.9×10-3). Our results provided novel insight into the molecular mechanism underlying the excessive chondrocyte apoptosis of KBD, and illustrated the application of EPEA for joint pathway analysis of microarray and eQTLs data. A program, named EPEA was developed to implement the proposed approach. You may know more here:http://www.cusabio.com/ELISA-Kit/Rat-Lysozyme-CLYZ-ELISA-kit-1042023.html

New gene found to cause a childhood cancer

Wilms tumour is a rare kidney cancer that occurs in children. It affects about one in ten thousand children, but fortunately, it is curable in about 90% of them. Recently a new study shows that genetic mutations in a genehttp://www.cusabio.com/ called REST were found in 16 children with Wilms tumour. They were shown to cause Wilms tumour. 9 of the child were the only member in their family to develop the cancer, but in 4 families over 1 child were cancered. The researchers estimated that REST mutations cause about 10% of familial Wilms tumour. The research is published today (Monday) in the journal Nature Genetics, and is part of the Factors Associated with Childhood Tumours (FACT) study, which is uncovering genetic causes of childhood cancers and has participants from more than 5,000 families. The FACT study is funded by the Wellcome Trust and the Rosetrees Trust, and the REST project involved international collaborators including from Baylor College of Medicine in Texas, US. The study was published in the journal Nature Genetics this Monday. It is also a part of the Factors Associated with Childhood Tumours (FACT) study. The FACT study is figuring out genetic causes of childhood cancers and has participants from more than 5,000 families. Because REST gene is critical in embryo development, it is well-studied. The new study gives a new role to REST in the field of human genetics. The mutations seems to compromise the normal functioning of REST in regulating the development of the embryo. The findings about the genehttp://www.cusabio.com/ELISA-Kit/Human-midregional-pro-atrial-natriuretic-peptide-MR-proANP-ELISA-kit-1042031.html can explain to many parents that why their children are cancered. Now the children can do a simple blood test to see who are at risk of cancer and may benefit from cancer screening. So the research is really valuable and significant.
