Study of damaged gene gives insight into causes of mental illness

Scientists have pinpointed how different types of damage in types of damage to the same gene can cause some people to suffer from schizophrenia while others have major depression.

Single gene is responsible for most cool temperature sensation

The discovery, reported in the May 3 issue of the journal Neuron, might one day lead to the development of drugs that induce cold sensation as an analgesic, or block it to prevent certain forms of chronic pain associated with cold sensation.

New hope for patients with premature aging condition progeria

There is renewed hope for treatment of a rare genetic condition that causes rapidly accelerated aging and leads to an average life expectancy of 13 years.

Scientists discover molecular mechanism that keeps HSV-1 activation restricted to a single gene for months or even years

By adulthood, most people have suffered at least one bout of painful cold sores brought on by the Herpes simplex virus 1, also known as HSV-1.

To live longer - eat less!

Scientists have known for a long time that animals fed diets which border on starvation live longer, but they are now saying that a particular gene is linked to calorie restriction.

Scientists discover way to distinguish pancreatic cancer from non-cancerous tissue

The research examined pancreatic cancer cells for tiny molecules called microRNA (miRNA). It shows that relative levels of certain miRNAs can distinguish pancreatic cancer from nearby noncancerous tissue and from inflamed pancreatic tissue.

OCT1 required for therapeutic effects of diabetes drug Metformin

The drug metformin is among the most widely prescribed drugs for the treatment of type 2 diabetes and results in an array of therapeutic benefits.

Expression pattern of microRNA may be useful in differentiating between chronic pancreatitis and pancreatic cancer

Pancreatic cancer is a lethal disease, with the annual deaths nearly equaling the incidence of 33,000 in the United States, according to background information in the article.

Variants of two genes involved in the inflammatory system linked to cognitive decline after heart surgery

Duke University Medical Center researchers believe their findings could help physicians identify patients at risk of suffering mental decline after heart surgery and raises the possibility that these patients could be treated with drugs that are known to dampen the inflammatory response.

Biomarker discovery bodes well for better cancer diagnostics

While new findings from Ohio State University scientists suggest a genetic marker that could help distinguish between chronic pancreatitis and pancreatic cancer and gauge who will do well with cancer treatment, a pharmacologist at the Kimmel Cancer Center at Jefferson in Philadelphia sees the discovery as much more.

Revolutionary treatment for blindness

The first clinical trial to test a revolutionary treatment for blindness in children has been announced by researchers at UCL (University College London).

Methods for marking molecules to identify gene alterations and metabolic shifts

Physical alterations of DNA in chromosomes can cause serious diseases such as Down syndrome, Prader-Willi syndrome, or cancer.

Simvastatin may help sufferers with Alzheimer's

Treatment with Simvastatin, one of the statin drugs widely used for lowering cholesterol in humans, significantly improved spatial memory - how to navigate a water maze - in mice genetically bred to have an Alzheimer's like disease.

Zorro-LNA stops genetic disorders in their tracks

A study to appear in the June 2007 issue of The FASEB Journal describes a new agent, called "Zorro-LNA," which has the potential to stop genetic disorders in their tracks.

Estrogen fluctuation affects epileptic seizures

In more than a third of women with epilepsy, seizures fluctuate across the menstrual cycle, due in part to continually fluctuating effects of estrogen on the neural circuitry in the hippocampus, a region of the brain involved in learning and memory - and in epileptic seizures.

RNA analysis can identify rejection in lung transplant patients

Recent data from the Lung Allograft Rejection Gene expression Observational (LARGO) study provides compelling evidence that profiling gene expression in peripheral blood can detect organ rejection in lung transplant patients.

House approves bill banning genetic discrimination

House lawmakers on Wednesday voted 420-3 to pass legislation (HR 493) that would ban discrimination against U.S. residents based on the results of genetic tests, CQ Today reports (Armstrong, CQ Today, 4/25).

Unicellular microRNA discovery

In the May 15th issue of Genes & Development, an international collaboration of researchers, led by Dr. Yijun Qi (National Institute of Biological Sciences, China), report on their discovery of microRNAs in the unicellular green alga, Chlamydomonas reinhardtii.
