Researchers create 'suped up' gene that forces cancer cells to self destruct

Researchers at the University of Rochester have designed a gene that produces a thousand times more protein in cancer cells than in healthy cells.

Restaurant workers and carpenters have highest risks for oesophagal cancer

A new study led by Spanish researchers has revealed that exposure to certain substances may increase the risk of cancer of the oesophagus.

Key survival circuit discovered in Salmonella bacteria

Hundreds of trillions of bacteria make their home in the vertebrate gut. Though many of these microbes perform helpful duties for their host, others - the pathogens - are unwelcome visitors, causing disease.

Cardiac stent patients with diabetes may benefit from drug that counteracts the effects of leptin

The naturally high levels of leptin in diabetic patients may reduce the effectiveness of drug-eluting stents used to treat heart blockages, but using a chemical that differs from the one commonly used to coat stents could counteract this effect.

Biopure submits IND for trial in patients with acute myeloid leukemia

Biopure Corporation has announced that it has submitted to the Food and Drug Administration (FDA) an investigational new drug (IND) application to conduct a pilot phase 2 clinical trial of the company's oxygen therapeutic Hemopure [hemoglobin glutamer - 250 (bovine)].

New anti-tumor gene called SARI

Researchers from Virginia Commonwealth University have identified a new anti-tumor gene called SARI that can interact with and suppress a key protein that is overexpressed in 90 percent of human cancers.

Discovery of new way a man can transmit the HIV virus to a woman

Scientists had long believed that the normal lining of the female vaginal tract was an effective barrier to invasion of the HIV virus during sexual intercourse. They thought the large HIV virus couldn't penetrate the tissue.

Researcher refines aptamers to prevent HIV resistance

Evolving HIV viral strains and the adverse side effects associated with long-term exposure to current treatments propel scientists to continue exploring alternative HIV treatments.

Trans-splicing therapy for spinal muscular atrophy closer to clinical use

Spinal muscular atrophy, a neurodegenerative disorder that causes the weakening of muscles, is the leading cause of infant death and occurs in 1 in 6,000 live births.

MRI scans can predict effects of multiple sclerosis 'flare-ups' on optic nerve

One of the most pernicious aspects of multiple sclerosis (MS) - its sheer unpredictability - may finally be starting to yield to advanced medical imaging techniques.

Just a little squeeze lets proteins assess DNA

To find its target, all a protein needs to do is give quick squeezes as it moves along the DNA strand, suggests new research from The University of Arizona in Tucson.

Mucosal lining of the female genital tract no barrier to HIV sexual transmission

Contrary to a widely-held assumption about heterosexual transmission of HIV, the normal mucosal lining of the female genital tract is not a foolproof barrier to viral penetration, scientists at the Northwestern University School of Medicine in Chicago report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Evolutionary roots of ancient bacteria may open new line of attack on cystic fibrosis

The redox-active pigments responsible for the blue-green stain of the mucus that clogs the lungs of children and adults with cystic fibrosis (CF) are primarily signaling molecules that allow large clusters of the opportunistic infection agent, Pseudomonas aeruginosa, to organize themselves into structured communities.

Both theories about human cellular aging supported by new research

Aging yeast cells accumulate damage over time, but they do so by following a pattern laid down earlier in their life by diet as well as the genes that control metabolism and the dynamics of cell structures such as mitochondria, the power plants of cells.

Single letter in the human genome points to risk for high cholesterol

Write out every letter in the human genome, one A, C, T or G per millimeter, and the text would be 1,800 miles long, roughly the distance from New York to Colorado.

Study of placenta unexpectedly leads to cancer gene

University of Rochester Medical Center scientists discovered a gene mutation that impairs the placenta and also is influential in cancer development, according to a study published online December 16, 2008, in the journal PLoS (Public Library of Science) Biology.

New technique to view labeled tumor cells in 'real' time

A breakthrough technique that allows scientists to view individually-labeled tumor cells as they move about in real time in a live mouse may enable scientists to develop microenvironment-specific drugs against cancer, researchers report at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.

Tracking the molecular pathway to mixed-lineage leukemia

Infants and adults with the blood cancer mixed-lineage leukemia (MLL) typically have a poor prognosis, and most infants die before their first birthdays.

New bone and tissue regeneration technique

Using stem cell lines not typically combined, researchers at Columbia University Medical Center have designed a new way to "grow" bone and other tissues.

Researchers stop ovarian cancer cell cycle in its tracks

Ovarian cancer cells are "addicted" to a family of proteins produced by the notorious oncogene, MYC, and blocking these Myc proteins halts cell proliferation in the deadliest cancer of the female reproductive system, according to a presentation by University of California, Berkeley scientists at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco.
