New unsuspected role for nuclear receptor corepressor protein

By knocking out a key regulatory protein, scientists at the University of California, San Diego School of Medicine and the Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland dramatically boosted insulin sensitivity in lab mice, an achievement that opens a new door for drug development and the treatment of diabetes.

ER-positive breast cancer patients with high levels of heat shock factor 1 experience poor outcomes

Whitehead Institute scientists report that patients whose estrogen receptor (ER)-positive breast cancers have high levels of the ancient cellular survival factor heat shock factor 1 (HSF1) experience poor outcomes—including increased mortality.

Researchers shed light on inner workings of endocycle

An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.

Scientists describe how protein acts as courier in cell signaling pathways

Normal development, from fertilized egg to adult organism, depends on each cell receiving proper instructions from its environment. In response to such incoming information, receptors on a cell's surface send signals to the nucleus that tweak gene expression and control cellular function.

La Jolla Institute becomes 5th participant in novel stem cell research collaboration

The La Jolla Institute for Allergy & Immunology has become the fifth organization in the prestigious Sanford Consortium for Regenerative Medicine, joining colleagues from the Salk Institute for Biological Studies, The Scripps Research Institute, University of California, San Diego and the Sanford-Burnham Medical Research Institute in the first-of-its-kind multi-institutional stem cell research collaboration.

Insulin resistance paradox

Obesity and insulin resistance are almost inevitably associated with increases in lipid accumulation in the liver, a serious disease that can deteriorate to hepatitis and liver failure. A real paradox in understanding insulin resistance is figuring out why insulin-resistant livers make more fat. Insulin resistance occurs when the body does a poor job of lowering blood sugars.

Scientists uncover vast new gene regulatory network linked with cancer

Researchers at Columbia University Medical Center (CUMC) and two other institutions have uncovered a vast new gene regulatory network in mammalian cells that could explain genetic variability in cancer and other diseases.

Study shows Sox2 expression in many adult stem cells

Investigators at the Massachusetts General Hospital (MGH) Center for Regenerative Medicine and the Harvard Stem Cell Institute (HSCI) have found that Sox2 - one of the transcription factors used in the conversion of adult stem cells into induced pluripotent stem cells (iPSCs) - is expressed in many adult tissues where it had not been previously observed.

Researchers discover cell differentiation mechanism

Researchers from the Haematopoietic Differentiation and Stem Cell Biology group at the Centre for Genomic Regulation (CRG), have described one of the mechanisms by which a cell (from the skin, for example) can be converted into another which is completely different.

New technique helps identify how RNA molecules control gene expression

A new technique developed by researchers at the Stanford University School of Medicine allows researchers to identify the exact DNA sequences and locations bound by regulatory RNAs. This information is necessary to understand how the recently identified RNA molecules control the expression of neighboring and distant genes.

Scientists identify oldest known DNA regulatory region

A team of scientists has discovered the oldest known DNA regulatory region, as reported in an article in the journal Proceedings of the National Academies of Sciences.

FoxM1 protein plays a critical role in development of medulloblastomas

Medulloblastomas constitute the most frequent class of malignant childhood brain tumor. Tumors of this type arise due to the uncontrolled proliferation of immature nerve cells in the developing brain, and there is no targeted treatment available.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

Kinexus launches TranscriptoNET KnowledgeBase for human gene expression study

Kinexus Bioinformatics Corporation, a world-leader in molecular intelligence research, announced the launch of its TranscriptoNET KnowledgeBase for the study of human gene expression in over 300 types of human tissues and organs as well as over 300 human cancer cell lines.

New pathway for type 2 diabetes

Newly diagnosed type 2 diabetics tend to have one thing in common: obesity. Exactly how diet and obesity trigger diabetes has long been the subject of intense scientific research.

Researchers identify novel sensory pathway that modulates pro-inflammatory cells

New research led by Derya Unutmaz, MD associate professor, the Departments of Pathology, Medicine, and Microbiology at NYU School of Medicine and Mark Sundrud, PhD, of Tempero Pharmaceuticals, Inc., has identified a novel sensory pathway that modulates the potency of Th17 cell responses.

New insights into genesis and development of Sézary syndrome

Scientists at Charité - Universitätsmedizin Berlin, Max Delbrück Center for Molecular Medicine (MDC) Berlin-Buch, the Max-Planck-Institut für Molekulare Genetik Berlin, and four other German institutes succeeded in proving a specific gene loss in a certain human lymphoma, the genesis of which is largely unexplained to date.

WSU professor receives NIH grant for non-alcoholic fatty liver disease research

Kezhong Zhang, Ph.D., assistant professor of molecular medicine and genetics and of immunology and microbiology in the School of Medicine at Wayne State University, was awarded $1.7 million by the National Institute of Diabetes and Digestive and Kidney Diseases of the National Institutes of Health to explore how molecular elements in the body regulate the development of non-alcoholic fatty liver disease.
