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.

New animal research finds life experiences influence brain development, behavior

Scientists presented new research today demonstrating the impact life experiences can have on genes and behavior. The studies examine how such environmental information can be transmitted from one generation to the next - a phenomenon known as epigenetics.

Scientists discover molecular basis for tamoxifen resistance and potential way to defeat it

In the last three decades, thousands of women with breast cancer have taken the drug tamoxifen, only to discover that the therapy doesn't work, either because their tumors do not respond to the treatment at all, or because they develop resistance to it over time. Now researchers at the University of California, San Francisco (UCSF) have discovered the molecular basis for tamoxifen resistance and found a potential way to defeat it.

Researchers show how ER-positive breast cancer tumors become resistant to tamoxifen

Researchers have shown how estrogen receptor-positive breast cancer tumors become resistant to tamoxifen, the only approved hormonal therapy for premenopausal patients with this type of breast cancer.

Combination of azacitidine and entinostat shows promise against NSCLC

A new type of therapy aimed at reversing the gene-silencing that promotes cancer-cell growth has shown promising results in a small clinical trial conducted by researchers at the Johns Hopkins Kimmel Cancer Center.

New epigenetic therapy may treat recurrent metastatic NSCLC

Patients with recurrent metastatic non-small cell lung cancer have a morbid prognosis, but a new epigenetic therapy may have potential in this population, according to data published in Cancer Discovery, a journal of the American Association for Cancer Research.

Prefrontal cortex neurons from individuals with autism show changes in chromatin structures

Neurons in the prefrontal cortex of individuals with autism show changes at numerous sites across the genome, according to a study being published Online First by the Archives of General Psychiatry, one of the JAMA/Archives journals.

Epigenetic alterations may play an important role in autism

Scientists at the University of Massachusetts Medical School are the first to map epigenetic changes in neurons from the brains of individuals with autism, providing empirical evidence that epigenetic alterations-changes in gene expression caused by mechanisms other than changes in the underlying DNA sequence-may play an important role in the disease.

Study on epigentics and cellular memory

How do fetal cells know what cell types to become? Why do cells in the adult body sometimes forget what they are and develop into cancer cells? These are some of the questions intensively investigated within the research field of epigenetics.

Exendin-4 drug could prevent later development of diabetes in children

Pediatric researchers who tested newborn animals with an existing human drug used in adults with diabetes report that this drug, when given very early in life, prevents diabetes from developing in adult animals. If this finding can be repeated in humans, it may become a way to prevent at-risk infants from developing type 2 diabetes.

First report on how patterns of 5-hmC's distribution change in mouse brain during development

In 2009, the DNA alphabet expanded. Scientists discovered that an extra letter or "sixth nucleotide" was surprisingly abundant in DNA from stem cells and brain cells.

Research focuses on JQ1 molecule that tricks NUT midline carcinoma cancer cells

NUT midline carcinoma (NMC) is a cancer without a cure, and one that affects all age groups. NMC is a rapid-growth disease with an average survival time of four and a half months after diagnosis, making the development of clinical trials for potential therapies or cures for this cancer difficult, to say the least.
