New opportunity for developing simple test to measure E2F4 activity in ER+ breast cancer patients

By looking at the expression levels of downstream genes of the regulators in breast cancer, investigators at Dartmouth Hitchcock's Norris Cotton Cancer Center, led by Chao Cheng, PhD, have identified a gene signature in E2F4 that is predictive of estrogen receptor positive (ER+) breast cancer.

Research findings may lead to new treatment strategies for Ewing sarcoma

The genetic abnormality that drives the bone cancer Ewing sarcoma operates through two distinct processes - both activating genes that stimulate tumor growth and suppressing those that should keep cancer from developing. These findings by Massachusetts General Hospital investigators, published in the November issue of Cancer Cell, may lead to new therapies targeting these aberrant mechanisms.

Researchers uncover mechanism that helps white fat cells to become browner

White adipose tissue stores excess calories as fat that can be released for use in other organs during fasting. Mammals also have small amounts of brown adipose tissue, which primarily acts as an effective fat burner for the production of heat. Now researchers from the University of Southern Denmark have uncovered the mechanism by which white fat cells from humans gets reprogrammed to become browner.

Tufts University study explores relationship between transcription, expansions of DNA repeats

Researchers in human genetics have known that long nucleotide repeats in DNA lead to instability of the genome and ultimately to human hereditary diseases such Freidreich's ataxia and Huntington's disease.

Study identifies H3.3 protein as key regulator in cellular senescence

Changes to the structure of the protein histone H3.3 may play a key role in silencing genes that regulate cancer cell growth, according to a study led by researchers from the Icahn School of Medicine at Mount Sinai and published online this month in the journal Nature Communications.

Researchers examine genomic landscapes of humans and mice

Looking across evolutionary time and the genomic landscapes of humans and mice, an international group of researchers has found powerful clues to why certain processes and systems in the mouse - such as the immune system, metabolism and stress response - are so different from those in people. Building on years of mouse and gene regulation studies, they have developed a resource that can help scientists better understand how similarities and differences between mice and humans are written in their genomes.

Scientists may have discovered new way to repair damaged tissue

By transforming human scar cells into blood vessel cells, scientists at Houston Methodist may have discovered a new way to repair damaged tissue. The method, described in an upcoming issue of Circulation (early online), appeared to improve blood flow, oxygenation, and nutrition to areas in need.

Two major studies newly implicate dozens of genes in autism

Two major genetic studies of autism, led in part by UC San Francisco scientists and involving more than 50 laboratories worldwide, have newly implicated dozens of genes in the disorder. The research shows that rare mutations in these genes affect communication networks in the brain and compromise fundamental biological mechanisms that govern whether, when, and how genes are activated overall.

Landmark study provides new insight into function of enzyme related to BRCA1 protein

A landmark study to be published in the October 30, 2014 print edition of the journal Nature provides new insight into the function of an enzyme related to the BRCA1 breast-cancer protein. The study by a team at Penn State University is the first to produce a detailed working image of an enzyme in the Polycomb Repressive Complex 1 (PRC1) -- a group that regulates cell development and is associated with many types of cancer.

Genetic differences contribute to risk for autism

Small differences in as many as a thousand genes contribute to risk for autism, according to a study led by Mount Sinai researchers and the Autism Sequencing Consortium, and published today in the journal Nature.

Researchers use DNA sequencing to uncover genes that heighten autism risk

In the largest study of its kind to date, researchers have used DNA sequencing to uncover dozens of genes that heighten the risk for autism. Joseph Buxbaum, Ph.D., Icahn School of Medicine at Mount Sinai, New York City, Mark Daly, Ph.D., Broad Institute of Harvard and MIT, and their colleagues examined more than 14,000 DNA samples from affected children, parents and unrelated people.

BRD4 protein appears to play key role in keeping stem cells in immature "pluripotent" state

A protein implicated in several cancers appears to play a pivotal role in keeping stem cells in an immature "pluripotent" state, according to a new study by NYU Langone Medical Center scientists.

New finding could accelerate research to regenerate damaged tissue

Scientists at NYU Langone Medical Center have found a way to boost dramatically the efficiency of the process for turning adult cells into so-called pluripotent stem cells by combining three well-known compounds, including vitamin C.

Collaborative study takes important step toward finding targeted treatments for bladder cancer

The story of cancer care seems so simple: find the mutated gene that causes cancer and turn it off or fix it. But rarely does a single gene cause cancer. More often, many genes are altered together to drive the disease. So the challenge becomes sorting out which altered genes are the most to blame in which cancers.
