Bacteria found in the mouth can block the HIV virus

Certain strains of bacteria that occur naturally in the human mouth can snare the HIV virus and even cells it has infected, according to researchers at the University of Illinois at Chicago College of Dentistry. They report their findings today at the 104th General Meeting of the American Society for Microbiology.

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals

Researchers have identified the first gene linked to the productivity of the stem cells that produce sperm in mammals. The discovery was made by applying the latest laboratory methods to a strain of mice restored from embryos frozen since the early 70s.

Genome research sheds light on Bardet-Biedl syndrome

By comparing the genomes of an alga, a weed and humans, a team of researchers has identified a new gene behind Bardet-Biedl syndrome (BBS), a complex condition marked by learning disabilities, vision loss and obesity.

Tumour suppressor gene family may be key to new colon cancer drugs

In the hunt for new cancer drug targets, scientists from the Johns Hopkins Kimmel Cancer Center and the Howard Hughes Medical Institute have discovered mutations in a family of genes linked to more than a quarter of colon cancers, as well as several other common cancers including breast and lung.

Cell division can be halted in multiple ways, with implications for cancer

Brown University researchers have found that there are multiple independent ways to stop cell division, a phenomenon that prevents the spread of genetic mutation, which can make cells cancerous. Results of this research, along with an accompanying editorial, were published in the current issue of the journal Molecular Cell.

Closer to understanding the function of a protein linked to an inherited form of the movement disorder dystonia

The protein, torsinA, is defective in patients with DYT1 dystonia, an inherited condition that causes uncontrollable movements in the limbs and torso. Learning what torsinA does could be an important step toward developing a treatment for the disorder.

Discovery of the gene for Cornelia de Lange syndrome

An international team of researchers has discovered the gene for Cornelia de Lange syndrome, a disabling, multisystem genetic disease that affects an estimated one in 10,000 children. The finding is expected to lead to a genetic test, enabling rapid and definitive diagnosis of the syndrome, as well as prenatal testing for families who already have one child with the disease.

Genetically engineered viruses may create new class of cancer therapies

A genetically engineered virus can selectively kill cancerous cells in the lung and colon while leaving healthy cells intact, according to new research published today in Cancer Research by William Wold and colleagues at Saint Louis University School of Medicine.

Risk of artery plaques increased by use of HIV drugs

An Italian study has provided evidence that HIV drugs called protease inhibitors may increase the risk of artery "plaques."

Particles in the air we breathe may pose genetic risks to humans

Particles in the air we breathe may pose genetic risks to humans and wildlife, according to new findings by researchers at McMaster University.

3 people with drug-resistant HIV become first to undergo a new form of gene therapy

The idea is to use a modified form of HIV to deliver an "antisense" gene to the immune cells that HIV infects. This is integrated into the cells' genome, and stays there until a cell is infected. Then it is switched on, and produces RNA complementary to the "sense" RNA encoding a viral protein. In theory, the RNAs should bind together, blocking viral replication.

Researchers identify new genes that control the formation of cilia found throughout the human body

Howard Hughes Medical Institute researchers have used a combination of brainpower and computer power to identify a multitude of new genes that control the formation of tiny, hair-like cilia that stipple the surfaces of many organs in a wide variety of creatures.

Chronic Fatigue Syndrome is nearly four times as common in veterans of the first Persian Gulf War as in nonveterans

Chronic Fatigue Syndrome (CFS) is nearly four times as common in veterans of the first Persian Gulf War as in nonveterans, according to a new study.

Ingenium's acquisition of US patents may lead to drug discovery and development

Ingenium Pharmaceuticals AG has acquired outright US patents no. 5,994,075 and no. 6,015,670 from Incyte Corporation, the company announced today.

Fat fighting undermined by over active eating pacemaker

They have revealed a set of pacemaker nerve cells in the brain that appear to underlie the drive to feed which itself feeds on a complex web of signals.

Soybeans may reduce the risk of colon cancer

A substance found in soybeans may reduce the risk of colon cancer, the third most common form of cancer in the world according to the World Health Organization.

New way by which cells can become cancerous may solve mystery with lung cancer

Researchers at The University of Texas M. D. Anderson Cancer Center are describing an entirely new way by which cells can become cancerous. And they say their finding provides an answer to a mystery in lung and other cancers.

Researchers find an entirely new way by which cells can become cancerous

Finding provides an answer to a mystery in lung and other cancers: why a potent tumor suppressor gene called FUS1 functions as it should, yet none of the protein it produces can be found anywhere in a cancer cell.

Research uncovers critical pieces of human genome

Researchers have found precisely the same sequences in the genomes of humans, rats, and mice; sequences that are 95 to 99 percent identical to these can be found in the chicken and dog genomes, as well.

Neurobiologists pinpoint region of the brain responsible for storing distant memories

For the first time, UCLA neurobiologists have pinpointed a region of the brain called the anterior cingulate as responsible for retrieving and storing distant memories. Published in the May 7 edition of Science, the findings may suggest new ways of treating memory disorders, including Alzheimer's disease and other dementias.
