WRN exonuclease structure and molecular mechanism imply an editing role in DNA end processing

A team of scientists from Lawrence Berkeley National Laboratory and the Scripps Research Institute has determined the crystal structure and molecular mechanisms of a key part of WRN, a protein that protects humans from premature aging and cancer.

Genetic data from an island population proves to be a useful tool in understanding disease

With fewer than 4,000 residents, the genetically isolated Micronesian island of Kosrae, in the West Pacific, provides an ideal population in which to research heritability of disease.

Researchers find gene connected to Lupus

Researchers at the University of Minnesota have identified a variant of a gene that is present in most people with lupus, a complex and chronic autoimmune disease.

New method designed to analyze the genes that regulate the immune system

Seattle scientists have developed a new method for analyzing the Major Histocompatibility Complex (MHC) of the human genome.

St. Jude develop strategy to speed future development of more effective and less toxic treatments for medulloblastoma

Investigators at St. Jude Children’s Research Hospital have developed a strategy to speed future development of more effective and less toxic treatments for medulloblastoma, a type of brain cancer. Medulloblastomas arise in the back of the brain and account for about 20 percent of childhood brain tumors.

Microarray analysis could lead to better understanding of mechanisms underlying the genetic propensity toward excessive drinking

The meta analysis, which examined more than 4.5 million data points on more than 100 microarrays from mouse models, also identified more than 1,300 functional groups, including signaling and transcription pathways, which may also play an important role in establishing a capacity for a "high level of alcohol consumption."

Fast tracking the healing process for common ear infections

The research will aim to understand why some eardrums heal by themselves (and why some do not heal at all) by identifying which genes are responsible for the wound-healing process of an infected human ear drum.

miR 155 overexpression can lead to cancer

Scientists in the Ohio State University Comprehensive Cancer Center say that just one, single, malfunctioning microRNA is sufficient to cause cancer in mice.

Researchers develop system for observing nuclear motion

The cell is understood to be highly organized, with specialized areas for different functions and molecular motors shuttling components around.

Genetic switch that links animal growth and cancer

Laboratory discoveries by scientists at two universities may lead to new directions in cancer therapy drugs. The researchers have discovered that a genetic switch involved in growth and development of an animal is the same one used to prevent normal cells from becoming cancerous.

Important new global mechanism for gene repression

Most of the time in most cells of the body, the great majority of genes are silenced, locked away within the compacted but orderly material that makes up chromosomes.

Chimpanzees and humans have gene variant, for different reasons

Gene variants determine which humans and which chimpanzees can taste bitter substances. For humans, this taste sensitivity may influence nutritional choices and ultimately their health, as well as behaviors, such as smoking.

Sticky proteins for neuro-chip chat

EU-funded researchers have taken the firsts steps towards future technologies combining silicon circuits and the nervous systems of mammals. Applications could include advanced drug screening and, perhaps one day, implants to help combat neurological disorders.

217 new targets for anti-cancer drugs

By identifying novel genes critical to cancer progression, biologists at the U.S. Department of Energy's Argonne National Laboratory have expanded the number of drug targets researchers have available for study to find ways to stop tumors in their tracks.

Obese may have gene which makes them fat

According to scientists in the U.S. there is a genetic explanation why some people are obese while others are not.

First gene therapy human trial in the United States for a form of muscular dystrophy under way

The clinical trial for Duchenne muscular dystrophy (DMD) tests the safety and effectiveness of a therapy that was developed over two decades by scientists at the University of North Carolina Chapel Hill's School of Medicine and the University of Pittsburgh.

Researchers find genetic "signature" that accurately identifies colon cancer

Researchers at Jefferson Medical College in Philadelphia have uncovered a genetic "signature" that accurately identifies colon cancer--a key, they hope, to better understand how the cancer develops.
