Anti-ageing gene could improve effects of getting old

According to scientists in the United States they have discovered a gene that can keep mice alive for 30% longer than normal.

Malaria researchers find the parasite's housebreaking tool

Plasmodium falciparum, the most lethal malaria parasite, is a housebreaking villain of the red blood cell world. Like a burglar searching for a way in to his targeted premises, the parasite explores a variety of potential entry points to invade the red blood cells of its human victims. When a weak point is found, the intrusion proceeds.

New vaccine protects more effectively against tuberculosis

Max Planck researchers have uncovered the mechanism by which the new genetically engineered tuberculosis vaccine functions.

Previously unknown family of plague virulence factors identified

Researchers at Duke University Medical Center have identified a previously unknown family of virulence factors that make the bacterium responsible for the plague especially efficient at killing its host.

Ataxin-1 affects the development of the nervous system

In some neurological diseases, too much of what is usually a good thing can be bad, said researchers at Baylor College of Medicine in a report in this week's issue of the journal Cell.

Nitric oxide synthase plays a role in peripheral vascular disease

The enzyme nitric oxide synthase plays a role in peripheral vascular disease, a common disease that impairs the mobility of 25 percent of people over the age of 50, according to a Yale study in the Proceedings of the National Academy of Sciences (PNAS).

UCI study helps identify one reason why women have lower stroke risk than men

Estrogen's role as an inhibitor of toxic-free radicals in cerebral blood vessels may be a key reason why premenopausal women have a lower stroke risk than men.

New knowledge into the molecular mechanisms involved in tumor growth

Scientists at the University of North Carolina at Chapel Hill have identified a molecular protein's critical role in cell division and growth.

Inflammation plays an important role in post-operative stroke

Duke University Medical Center researchers have discovered that patients who have two specific gene variants are more than three times as likely to suffer a stroke after heart surgery.

New strategy to turn off the function of a special group of T cells to suppress immune response to tumors

A special stretch of genetic material may turn off the immune suppression that stymies attempts to fight cancer with a vaccine, said researchers at Baylor College of Medicine (BCM) at Houston.

First clinical trial of a biologic nanoparticle designed to give back to cancer patients the tumor-busting gene they have lost

The phase I clinical study will enroll 20 patients with advanced solid cancers (including most common tumor types), and is the culmination of more than a decade of work by a team of researchers led by Professor Esther H. Chang, Ph.D. at the Lombardi Comprehensive Cancer Center.

Genomics reveals mechanisms that engineer remarkable heat resistance in bacteria

Warm-blooded creatures maintain a relatively stable body temperature that cannot tolerate the stress of intense heat (or cold). When it's too hot proteins destabilize and degrade--in some cases, with fatal results.

First human gene mutation that causes extreme farsightedness

Working with an Amish-Mennonite family tree, Johns Hopkins researchers at the Wilmer Eye Institute have discovered what appears to be the first human gene mutation that causes extreme farsightedness.

Hundreds of identified genes involved in the pathophysiology of ulcerative colitis and Crohn disease

In a paper published in PLoS Medicine researchers from the German Genome Research Network have analysed the expression of thousands of genes from patients with inflammatory bowel disease (ulcerative colitis and Crohn disease) using a genome wide approach to produce a comprehensive picture of which genes are activated in these conditions.

Mouse model of Rett Syndrome displays reduced cortical activity

Sacha Nelson of Brandeis University in Waltham, MA and Rudolf Jaenisch of the Whitehead Institute of Biomedical Research in Cambridge, MA and their colleagues report online in the Proceedings of the National Academy of Sciences Early Edition that spontaneous neuronal activity is reduced in the cortex of a knockout mouse model for the childhood neurodevelopmental disorder, Rett Syndrome.
