Modifications in key epigenetic markers influence human embryonic stem cells

Scientists have long known that control mechanisms known collectively as "epigenetics" play a critical role in human development, but they did not know precisely how alterations in this extra layer of biochemical instructions in DNA contribute to development.

Gene offers new insights into treatment strategies for deep-vein thrombosis

A gene associated with both protection against bacterial infection and excessive blood clotting could offer new insights into treatment strategies for deep-vein thrombosis -- the formation of a harmful clot in a deep vein.

Researchers find deficiency in anti-tumor protein can delay DNA repair after radiation treatment

Researchers at Moffitt Cancer Center have found that a deficiency in an important anti-tumor protein, p53, can slow or delay DNA repair after radiation treatment. They suggest that this is because p53 regulates the expression of two enzymes (JMJD2b and SUV39H1) that control the folding of DNA.

National Jewish Health researchers unravel mystery of adjuvants

Aluminum salts, or alum, have been injected into billions of people as an adjuvant to make vaccines more effective.

Study links mutated histone protein to rare brain stem cancer in children

Most cancer treatments are blunt. In an attempt to eradicate tumors, oncologists often turn to radiation or chemotherapy, which can damage healthy tissue along with the cancerous growths.

Inflammation and epigenetics: an interview with Dr Belkina and Dr Denis, Boston University School of Medicine

Inflammation can be thought of as taking two major forms: acute or chronic. Acute inflammation, which can be painful, usually arises quickly and resolves quickly. It accompanies bacterial infections, traumatic injury and is useful to fight infections and promote healing.

UCI study finds novel molecular mechanism that helps trigger formation of long-term memory

UC Irvine neurobiologists have found a novel molecular mechanism that helps trigger the formation of long-term memory. The researchers believe the discovery of this mechanism adds another piece to the puzzle in the ongoing effort to uncover the mysteries of memory and, potentially, certain intellectual disabilities.

Protein with key job in muscle function moonlights in nucleus to help regulate genes

A key building block of life, actin is one of the most abundant and highly conserved proteins in eukaryotic cells.

Study uncovers new relationship between nuclear architecture, gene activity

Every time a cell divides it makes a carbon copy of crucial ingredients, including the histone proteins that are responsible for spooling yards of DNA into tight little coils.

Cocaine can be lethal for people living with HIV

Cocaine, already a damaging drug for those with healthy immune systems, can be lethal for those living with human immunodeficiency virus. Mudit Tyagi, Ph.D., assistant professor of medicine at the George Washington University School of Medicine and Health Sciences, has received two federally funded grants to study how dangerous this combination is in HIV patients.

UNC1215 chemical probe can help investigate L3MBTL3 methyl-lysine reader domain

In an article published as the cover story of the March 2013 issue of Nature Chemical Biology, Lindsey James, PhD, research assistant professor in the lab of Stephen Frye, Fred Eshelman Distinguished Professor in the UNC School of Pharmacy and member of the UNC Lineberger Comprehensive Cancer Center, announced the discovery of a chemical probe that can be used to investigate the L3MBTL3 methyl-lysine reader domain.

Researchers identify mechanisms that connect variety of diseases linked with inflammation

A study led by researchers at Boston University School of Medicine (BUSM) has identified epigenetic mechanisms that connect a variety of diseases associated with inflammation.

Researchers map complex interactions of proteins that control inflammation

Inflammatory response plays a major role in both health protection and disease generation. While the symptoms of disease-related inflammatory response have been know, scientists have not understood the mechanisms that underlie it.

Study shows importance of lncRNAs for regulation of adipogeneis

Whitehead Institute researchers have identified a previously unrecognized layer of genetic regulation that is necessary for the generation of undesirable white fat cells. When this regulation is disrupted, white fat cells are unable to accumulate lipid droplets or mature from their precursors.

Tousled-like kinases play a key role in suppression and activation of herpesviruses

Kaposi's sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV) hide within the worldwide human population. While dormant in the vast majority of those infected, these active herpesviruses can develop into several forms of cancer.

RNF20 protein required for MLL-rearranged leukemia amplification

Acute myeloid leukemia (AML) is an aggressive blood cancer that is currently incurable in 70% of patients. In a bold effort, CSHL scientists are among those identifying and characterizing the molecular mechanisms responsible for this cancer in order to generate potential new therapeutics.
