Man and mouse share genome structures

In the most detailed large-scale study to date of the proteins that package DNA, researchers have mapped a family of switches that turn genes on and off. Their findings may help scientists understand regulatory mechanisms underlying cancer and human development. The res...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

... called PGC-1beta. Until now, scientists lacked a detailed explanation of how saturated and trans fats caused an increase in blood cholesterol and triglycerides, while diets high in unsaturated and polyunsaturated fats did not. Evidence pointed to the liver, which is responsible for the body's synthesis of t...

Male circumcision reduces risk of HIV transmission from women to men

...lleaguesfrom the United States and Kenya collected detailed sexual data from agroup of male Kenyan truckers and, using statistical models, developedinfectivity measures that estimate the per-sexual-act probability ofHIV transmission. The study is the first to calculate the probabilityof infection for men who ...

Ecological destruction fuels emerging diseases

... different diseases, something that will require a detailed understanding of their often complex multi-host life cycles. "It's very difficult to link these things up," he says. "It's very time consuming to do that, but without that information we don't know how these parasites are transmitted." And without ...

Breakthrough Microarray-based Technology for the Study of Cancer

...ity and flexibility of themicroarray platforms. As detailed in the PNAS paper, Agilent'sbreakthrough is founded on the modification of its gene-expressionprofiling microarray technology to improve its utility for DNA analysisapplications. This new platform provides high sensitivity, enabling CGHresearchers to...

Spider Venom Could Yield Eco-Friendly Insecticides

... King's NSF-funded research has provided the first detailed descriptions of the regions of the toxins that are essential for interaction with insect ion channels. (Ion channels allow the movement of ions -- small charged molecules -- across cell membranes.) His next challenge is to use this information to de...

Protein Packages Found To Activate Genes; May Be What Regulates Development And Disease

...of Technology (M.I.T.). They did the largest, most detailed study to date of the protein structure that surrounds the human genome. Their findings reveal surprising and previously unknown specifics of how genes get switched on during development of the human body and in diseases such as cancer. "Each type o...
