Epigenetics is the study of chemical reactions that influence gene expression, through activation or deactivation of genes at specific times and locations.

Special hearing on potential environmental health factors associated with autism spectrum disorders

Autism Speaks' Chief Science Officer Geraldine Dawson, Ph.D. emphasized the importance of research on environmental risk factors for autism spectrum disorders as the U.S. Senate Committee on Environment & Public Works, Subcommittee on Children's Health convened a special hearing on potential environmental health factors associated with autism spectrum disorders (ASD) and related neurodevelopmental disorders. The hearing is examining the latest research on potential environmental factors that may increase the risk for autism spectrum disorders.

Exposure of mBM-MSCs to VPA increases hepatic differentiation

Recent studies suggest that MSCs possess a greater differentiation potential than once thought and several hepatic differentiation protocols from bone marrow cells have been established. However, the incidence of bone marrow-derived hepatocytes was low. Moreover, a long culture period is needed in most cases.

Epigenetic changes to DNA in breast cancers linked with environmental risk factors, tumor size: Study

Researchers from Brown University and the University of California San Francisco have found that epigenetic changes to DNA in breast cancers are related to environmental risk factors and tumor size, providing a window into the severity of the disease. The study is published in today's edition of PLoS Genetics. The researchers found that epigenetic profiles of tumors had a direct association with diet, alcohol, and tumor size.

Researchers reveal findings on restricted lineage of iPS cells

Adult cells that have been reprogrammed into induced pluripotent stem cells (iPS cells) do not completely let go of their past, perhaps limiting their ability to function as a less controversial alternative to embryonic stem cells for basic research and cell replacement therapies, according to researchers at Children's Hospital Boston, John Hopkins University and their colleagues

Tet 1 protein helps stem cells renew themselves and stay pluripotent: Researchers

Take a skin cell from a patient with Type 1 diabetes. Strip out everything that made it a skin cell, then reprogram it to grow into a colony of pancreatic beta cells. Implant these into your patient and voilà! She's producing her own insulin like a pro.

AMPK may regulate epigenetic mechanism: Research

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.Biologists have been studying how AMPK works for several decades and know that once it is activated, AMPK turns on a large number of genes by passing the "make more energy" message through numerous signaling cascades in the cell. What was not known, until now, was that AMPK also works via an epigenetic mechanism to slow down or stop cell growth.

Epizyme publishes two new review papers on epigenetics

Epizyme, Inc., a company leading the discovery and development of first-in-class, targeted cancer therapeutics against epigenetic targets, announced today the publication of two new review papers in the area of epigenetics. Together, the articles provide an overview of the major epigenetic enzyme classes, as well as chemical biology approaches for discovering small molecule inhibitors of these epigenetic enzymes, and demonstrate Epizyme's scientific leadership in the area of epigenetics.

Researchers develop new strategy for treating multiple myeloma

Multiple myeloma is one of the most common blood cancers, and at present considered to be incurable. In a new study from Uppsala University, researchers now present a conceptually new model for the development and progression of multiple myeloma. The study was done in collaboration with Vrije Universitet Brussels and is published in the July edition of the on-line journal PLoS ONE.

Smokers exposed to wood smoke are at increased risk of COPD: Research

Smokers who are exposed to wood smoke, either through home heating and cooking or through ambient neighborhood pollution, are not only at increased risk of COPD, but are also more likely to have epigenetic changes in the DNA that further increase their risk of COPD and related pulmonary problems.

Pre-clinical study results of EVP-0015962 presented at AAICAD 2010

EnVivo Pharmaceuticals today announced at the Alzheimer's Association 2010 International Conference on Alzheimer's Disease results from its proprietary gamma-secretase modulator pre-clinical study. In a transgenic mouse model, EnVivo's EVP-0015962 reduced amyloid plaque buildup which is believed to be a cause of Alzheimer's disease, reversed behavioral deficits and reduced brain inflammation associated with Alzheimer's disease.

The Samuel Waxman Cancer Research Foundation announces research grants totaling $1.54 million

The Samuel Waxman Cancer Research Foundation (SWCRF) has awarded 13 collaborative research grants and 3 individual research grants, totaling $1.54 million. The 16 grants represent a portion of the science grant program at the Foundation, which will award more than $2 million this year to cancer research.

Subtle mutation affecting epigenome may lead to inherited form of mental retardation: Researchers

A subtle mutation affecting the epigenome –- a set of dynamic factors that influence gene activity -- may lead to an inherited form of mental retardation that affects boys, find researchers at Children's Hospital Boston. The disorder, which also involves cleft lip or cleft palate, appears to hinge on an enzyme working in a biological pathway that may offer several potential drug targets.

Promising study may lead to potential new therapeutics for women facing triple-negative breast cancer

Using a small molecule decoy, investigators funded by the Samuel Waxman Cancer Research Foundation have managed to block protein interactions and induce epigenetic reprogramming in human and mouse breast cancer cells, essentially changing the gene expression of breast cancer cells to behave in a more normal manner.

Research findings may help scientists understand how muscle and heart diseases develop

Researchers from Mount Sinai School of Medicine have identified a previously unknown mechanism by which cells direct gene expression, the process by which information from a gene is used to direct the physical and behavioral development of individuals. The research, which may help scientists gain insight into how muscle and heart diseases develop, is published in the July 8th issue of Nature.

Epigentek develops new approach for identification of "sixth DNA base" 5-hmC

Research experts in the epigenetic field from Epigentek have developed a new, breakthrough approach for the identification of the "sixth DNA base," 5-hydroxymethylcytosine (5-hmC). This technology is based on a high throughput, strip-well format and is also incorporated into the first commercially available product, the MethylFlash(TM) Hydroxymethylated DNA Quantification Kit, for rapidly quantifying hydroxymethylated DNA.

New insights into cancer hallmarks in induced pluripotent cells

The therapeutic potential of embryonic stem cells has been an intense focus of study and discussion in biomedical research and has resulted in technologies to produce human induced pluripotent stem cells (hiPSCs). Derived by epigenetic reprogramming of human fibroblasts, these hiPSCs are thought to be almost identical to human embryonic stem cells (hESCs) and provide great promise for patient-tailored regenerative medicine therapies.
