Tonsil epithelial factors may influence oropharyngeal HIV transmission

Current research demonstrates that the tonsils may possess the necessary factors to act as a transmission site for the spread of HIV.

Scientits devise dimmer swith to regulate gene expression in mammal cells

Three Boston University biomedical engineers have created a genetic dimmer switch that can be used to turn on, shut off, or partially activate a gene's function. Professor James Collins, Professor Charles Cantor and doctoral candidate Tara Deans invented the switch, which can be tuned to produce large or small quantities of protein, or none at all.

New findings on gene-transcription machinery

For some time, scientists have been tracking down the sequence of biochemical steps required to attract and assemble at the head end of a gene the molecular machinery needed to transcribe that gene to put to work the information it encodes.

Call for EU to launch major project to map out all our proteins

Biologists still have no clear idea how many active genes there are coding for proteins in humans and other organisms, even though for some species the genomes have been completely sequenced.

New gene therapy for 200 inherited forms of blindness

An improved approach to gene therapy may one day treat some of the nearly 200 inherited forms of blindness, scientists at Washington University School of Medicine in St. Louis suggest.

Itchy and scratchy gene discovered

Itching for a better anti-itch remedy? Your wish may soon be granted now that scientists at Washington University School of Medicine in St. Louis have identified the first gene for the itch sensation in the central nervous system.

Tetrabenazine protects brain cells in Huntington's disease model

A drug used in some countries to treat the symptoms of Huntington's disease prevents death of brain cells in mice genetically engineered to mimic the hereditary condition, UT Southwestern Medical Center researchers have found.

Effects of aging hematopoietic stem cells

There is little disagreement that the body's maintenance and repair systems deteriorate with age, even as there is plenty of disagreement as to why.

Discovery of novel 'molecular dictator with a conscience'

University of New South Wales (UNSW) researchers have uncovered an important naturally occurring mechanism in the body where "bad" cells that cause blockages in our blood vessels are kept under strict growth control, while "good" cells that keep our blood vessels free of clots and growths are left unaffected.

Good diet + exercise = less insulin in the brain and a longer life!

Scientists in the U.S. say reducing the action of insulin in the brain could well be the secret to longevity.

Protein IKKa protects checkpoint gene from chemical shutdown

A protein that is largely absent in one type of skin cancer protects an important gene in a cell's defense against harmful mutations from being silenced, researchers at The University of Texas M. D. Anderson Cancer Center report in the July 20 edition of Molecular Cell.

Xenotransplantation from pigs getting closer

Experiments using pigs genetically engineered for compatibility with the human immune system have raised hopes that cross-species transplantation could soon become an option for patients with diabetes and other currently incurable diseases.

Eat a good diet and exercise to live longer

The traditional prescriptions for a healthy life sensible diet, exercise and weight control extend life by reducing signaling through a specific pathway in the brain, according to Howard Hughes Medical Institute researchers who discovered the connection while studying long-lived mice.

Three gene variants discovered that help fight HIV

An international team of researchers has identified three gene variants in the DNA of 486 people infected with HIV that appear to have helped some of the patients fight off the virus and delay the onset of full-blown AIDS.

Clearer picture of host responses to HIV virus

The first genome-wide association study of an infectious disease, conducted by an international group of researchers through the Center for HIV/AIDS Vaccine Immunology (CHAVI), has yielded a new understanding of why some people can suppress virus levels following HIV infection.
