Study reveals central role played by DBIRD protein complex in gene transcription

In a study published this week in the journal Nature, researchers at the University of Liège's GIGA Unit, together with English and German teams, reveal the central role played by a protein complex, unknown up to now, in gene transcription.

Researchers identify gene that influences how we respond to flu infection

A genetic finding could help explain why influenza becomes a life-threating disease to some people while it has only mild effects in others. New research led by the Wellcome Trust Sanger Institute has identified for the first time a human gene that influences how we respond to influenza infection.

MicroRNAs linked to imminent threat of heart attack

Researchers at the Intermountain Medical Center Heart Institute have, for the first time ever, made a connection between tiny genetic molecules called microRNAs and the imminent threat of a heart attack, according to a new study.

Israel says no to skinny models

The Israeli Parliament has moved to ban skinny models from appearing in that nation's media. It has won approval in Tel Aviv on Monday, and to American experts on eating disorders, the measure is a clear step toward a key goal: promoting more realistic body images among girls and women.

Male pattern baldness causes discovered

Most men start to go bald in middle age, with about 80% of men having some hair loss by the age of 70. Male pattern baldness is the most common type of hair loss for men, the National Institute of Health said. Symptoms include a thinning of hair at the hairline, eventually creating a U-shaped or horseshoe pattern of hair on both sides of the head. The male sex hormone testosterone plays a key role, as do genetic factors. They cause the hair follicles to shrink, eventually becoming so small that they are invisible, leading to the appearance of baldness. While treatment is not necessary, side effects including psychological stress and loss of self-esteem due to change in appearance can be experienced.

Testosterone may play a role in treatment of triple negative breast cancer

Could blocking a testosterone receptor lead to a new way to treat an aggressive form of breast cancer? That's a question researchers at Mayo Clinic in Arizona and the Translational Genomics Research Institute (TGen) are exploring. Preliminary results of a Mayo Clinic - TGen collaborative study shows the testosterone receptor may be a potential target to attack in treating triple negative breast cancer (TNBC).

Multiresistant bacteria withstand wastewater treatment processes

Large quantities of antibiotic-resistant bacteria enter the environment via municipal - and especially hospital - wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous - multiresistant - strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

Genetic marker identifies tumors unable to repair DNA damage by platinum agents

Scientists from Brigham and Women's Hospital and Dana-Farber Cancer Institute and their colleagues have found a genetic marker that predicts which aggressive "triple negative" breast cancers and certain ovarian cancers will likely respond to platinum-based chemotherapies.

Obese children with PNPLA3 and GCKR genetic variants more susceptible to fatty liver disease

New research found the genetic variant Patatin-like phospholipase domain containing protein-3 (PNPLA3) acting in conjunction with the glucokinase regulatory protein (GCKR) is associated with increased susceptibility to fatty liver disease in obese children.

UC Riverside to study molecular basis of hormonal regulation of mosquito reproduction

Female mosquitoes require energy for their egg development, which they acquire from vertebrate blood. But by sucking on blood, they become vectors of numerous disease pathogens of human and domestic animals. If the mechanisms that govern their egg production are better understood, novel approaches to controlling the reproduction and population of mosquitoes can be devised.

Scripps scientists generate synthetic memory trace

Scripps Research Institute scientists and their colleagues have successfully harnessed neurons in mouse brains, allowing them to at least partially control a specific memory. Though just an initial step, the researchers hope such work will eventually lead to better understanding of how memories form in the brain, and possibly even to ways to weaken harmful thoughts for those with conditions such as schizophrenia and post traumatic stress disorder.

TAS2R38 and CD36 gene may play a role in fat perception

While high-fat foods are thought to be of universal appeal, there is actually a lot of variation in the extent to which people like and consume fat. A new study in the March issue of the Journal of Food Science, published by the Institute of Food Technologists, reported that two specific genes, may play a role in some people's ability to taste and enjoy dietary fat.

Scientists artificially derive brain stem cells from connective tissue of mice

These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells.

Blocking PFKFB4 enzyme could prevent growth of prostate cancer cells

Cancer Research UK scientists have discovered how blocking a key enzyme, which helps convert glucose into energy, could provide a new way to kill prostate cancer cells, according to a study published in the journal Cancer Discovery.

UI receives three grants to hasten discovery of new TB therapeutics

Forty-five years. That's how long it's been since the last drug - rifampin - hit the market to treat tuberculosis, an infection that affects nearly one third of the world's population and causes 1.8 million deaths annually. The University of Illinois at Chicago College of Pharmacy has received three new federally-funded grants to hasten the discovery of new therapeutic treatments.

PFKFB4 gene leads to excessive growth of prostate cancer cells

Cancer cell metabolism may present a new target for therapy as scientists have uncovered a possible gene that leads to greater growth of prostate cancer cells.

Verapamil drug may reverse diabetes-related death of pancreatic beta cells

A common high-blood-pressure medication appears to reverse the diabetes-related death of pancreatic beta cells, according to a University of Alabama at Birmingham study published today in the journal Diabetes.

Study identifies abnormal brain gene expression patterns in autism

A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets that could lead to discoveries of new prevention strategies and treatment for the disorder.

WCI technique uses MRS to detect oncometabolites

Researchers at Winship Cancer Institute have developed a technique for detecting an "oncometabolite", a chemical produced by some brain tumors' warped metabolism, via non-invasive imaging.
