Epigenetics News and Research

RSS

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

Negative effects of environmental toxicants can pass across generations

A Washington State University researcher has demonstrated that a variety of environmental toxicants can have negative effects on not just an exposed animal but the next three generations of its offspring.

REST molecule acts as an adapter in stem cells, times neuronal development

Upon fertilisation, a single cell is formed when egg and sperm fuse. Our entire body, with more than 200 specialised cell types and billions of cells are formed from this single cell. It is a scientific mystery how the early stem cells know what cell type to become, but a precise timing of the process is crucial for correct development and function of our body.

Call for Expression of Interest to attend personalised medicine conference

The Call for Expression of Interest to attend or present at the Conference on Personalised Medicine: Better Healthcare in Cyprus in June 2012 is now open. The deadline is 1 April 2012.

HDAC2 enzyme could be a potential target for new Alzheimer's drugs

MIT neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms.

Childhood adversity may lead to epigenetic changes in glucocorticoid receptor gene

In a look at how major stressors during childhood can change a person's biological risk for psychiatric disorders, researchers at Butler Hospital have discovered a genetic alteration at the root of the association.

Study evaluates how environmental triggers might alter epigenetics of CFS

A University of Toronto Scarborough (UTSC) researcher is examining how environmental triggers might alter gene function in people with Chronic Fatigue Syndrome. The research could lead to better insights into the disease and eventually to new treatments.

OGF-OGFr axis discovery provides new insights into ovarian cancer

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the presence and integrity of the opioid growth factor receptor (OGFr), which mediates the inhibitory action of opioid growth factor (OGF) on cell proliferation, is a key to understanding the progression and treatment of human ovarian cancer.

Symposium discusses links between genetic, epigenetic and environmental influences on autism

Two UC Davis MIND Institute researchers will lead a symposium on relationships between genetic, epigenetic and environmental influences on the development of autism in children during the American Association for the Advancement of Science (AAAS) Annual Meeting, Feb. 16 -18 in Vancouver, Canada.

Scientists observe maturation of immune cells in live zebrafish embryos

T-cells are the immune system's security force. They seek out pathogens and rogue cells in the body and put them out of action. Their precursors are formed in the bone marrow and migrate from there into the thymus. Here, they mature and differentiate to perform a variety of tasks. Scientists at the Max Planck Institute of Immunobiology and Epigenetics in Freiburg have now succeeded for the first time in observing the maturation of immune cells in live zebrafish embryos.

Exposure to common flame retardant may affect fertility and long-term memory

Mice genetically engineered to be susceptible to autism-like behaviors that were exposed to a common flame retardant were less fertile and their offspring were smaller, less sociable and demonstrated marked deficits in learning and long-term memory when compared with the offspring of normal unexposed mice, a study by researchers at UC Davis has found.

Epigenetic mechanisms maintain tolerance in T cells specific for self antigens

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually pose no risk to health (self-antigens).

Unstructured free play, recess need to be reinstated in schools

Evaluating the Let's Move! Initiative, Dr. Melinda Sothern, Professor of Public Health and Jim Finks Chair of Health Promotion at LSU Health Sciences Center New Orleans, calls First Lady Michelle Obama brave for taking on the challenge of childhood obesity and suggests that she now consider working to move it up to the policy level.

Preterm birth interventions should be tailored for underlying risk factors and pathways

In a study to be presented today at the Society for Maternal-Fetal Medicine's annual meeting, The Pregnancy Meeting -, in Dallas, Texas, researchers will report findings that indicate that preterm birth interventions should be tailored for underlying risk factors and pathways.

Mental illness suspect genes are among the most environmentally responsive regulatory mechanisms

For the first time, scientists have tracked the activity, across the lifespan, of an environmentally responsive regulatory mechanism that turns genes on and off in the brain's executive hub.

Cancer Genomics now available online

Genome Research publishes online and in print today a special issue entitled, "Cancer Genomics," highlighting insights gained form cutting-edge genomic and epigenomic analyses of cancer.

Researchers decipher genetic material of 48 pediatric glioblastomas

Glioblastomas grow extremely aggressively into healthy brain tissue and, moreover, are highly resistant to radiation therapy and chemotherapy. Therefore, they are regarded as the most malignant type of brain tumor. Currently available treatment methods are frequently not very effective against this type of cancer. Glioblastoma can affect people of all ages, but is less common in children than in adults.

Newly discovered molecular pathway may explain how AML develops

Researchers at UC Santa Barbara have discovered a molecular pathway that may explain how a particularly deadly form of cancer develops. The discovery may lead to new cancer therapies that reprogram cells instead of killing them. The findings are published in a recent paper in the Journal of Biological Chemistry.

Novel detection of ovarian cancer in early stages

Ovarian cancer is often detected at a late stage and it is the leading cause of death due to gynecological cancers, and the sixth leading cause of cancer death in women. According to latest discovery by researchers at Sydney’s Garvan Institute there may be a way this killer cancer is detected earlier.

Scientists discover finely tuned mechanism associated with CHD

Scientists at the Gladstone Institutes have identified a finely tuned mechanism by which fetal heart muscle develops into a healthy and fully formed beating heart-offering new insight into the genetic causes of congenital heart disease and opening the door to one day developing therapies to fight this chronic and potentially fatal disorder.
