New strategy to identify differences between non-metastatic and highly metastatic breast cancer cells

Researchers at the University of California, San Diego have used a new strategy to identify differences between non-metastatic and highly metastatic breast cancer cells. The article by Valerie Montel et al., "Expression profiling of primary tumors and matched lymphatic and lung metastases in a xenogeneic breast cancer model," appears in the May 2005 issue of The American Journal of Pathology and is accompanied by a commentary.

RNA interference permanently silences key breast cancer gene

In laboratory mouse experiments, researchers at The University of Texas M. D. Anderson Cancer Center have developed a way to use RNA interference (RNAi) so that it permanently hampers breast cancer development. The technique permanently silences activated STAT3, a crucial gene found in some human breast tumors, thus reducing the cancer's ability to become invasive.

Reducing expression of a gene called BRCC36 makes breast cancer cells more responsive to ionizing radiation

The research was presented today at the 96th Annual Meeting of the American Association for Cancer Research (AACR) in Anaheim, Calif. BRCC36 directly interacts with the BRCA1 protein. Almost all invasive breast cancer cells have elevated BRCC36 levels compared to normal breast milk-duct cells.

Researchers insert engineered human stem cells into the spinal cords of ALS-afflicted rats

Unveiling a delivery method that may one day help surgeons treat the deadly neurodegenerative disease amyotrophic lateral sclerosis (ALS), researchers at the University of Wisconsin-Madison have inserted engineered human stem cells into the spinal cords of ALS-afflicted rats.

Strawberries destroy cancer cells

Researchers specializing in the health benefits of plant compounds have shown that quercetin, a phytonutrient found in abundance in strawberries and other fruits, can induce programmed self-destruction of human cancer cells.

Green tea extract has potential as an anti-cancer agent

A new study on bladder cancer cells lines shows that green tea extract has potential as an anti-cancer agent, proving for the first time that it is able to target cancer cells while leaving healthy cells alone.

Inserting corrective genes into the brain to fight Parkinson's disease

An international team of scientists has used gene therapy in two separate studies to renew brain cells and restore normal movements in monkeys and rats with a drug-induced form of Parkinson's disease.

African drug Ibogaine blocks alcohol cravings

A naturally occurring hallucinogen advocated by some clinicians as a potent anti-addiction drug has been rigorously studied for the first time, confirming its ability to block alcohol craving in rodents, and clarifying how it works in the brain.

NIH begins Phase 1 clinical trial of HIV vaccine candidate

GenVec announced today that the National Institute of Allergy and Infectious Diseases (NIAID), National Institutes of Health (NIH), has begun the second Phase 1 clinical trial in healthy adult volunteers of an HIV vaccine candidate jointly developed by the Dale and Betty Bumpers Vaccine Research Center (VRC), a part of NIAID, and GenVec.

Rett Syndrome, the first identified epigenetic disease - linked to specific defects in the three-dimensional folding of chromatin

Sometime between the age of 6 and 18 months, after a period of seemingly normal development, girls affected with Rett Syndrome lose interest in play; they gradually become withdrawn and anxious, develop autistic-like behaviors, and acquire specific symptoms like repetitive teeth-grinding and hand-wringing.

Unusual protein pair that stops blood vessels' growth in the developing back

In experiments with mice, a research team led by Johns Hopkins scientists has discovered an unusual protein pair that stops blood vessels' growth in the developing back.

Fluorescent protein tool may speed identification of molecular changes that reveal cells' inner workings

Scientists at Johns Hopkins and the University of Texas Medical Branch have created a new tool that easily reveals when and where a key cellular signal is active.

Enzyme that normally alters the activity of other protein molecules in cells may also help prevent cancer

The enzyme is known as PTPRO (for “protein tyrosine phosphatase receptor-type O”). When the gene responsible for producing PTPRO is silenced, as can happen in lung cancer, for example, the amount of the enzyme drops, allowing the cells to grow when they shouldn’t.

Scientists are testing the effectiveness of a new type of flu vaccine

The experimental vaccine instead relies on a cell line drawn from insects known as silk moths, which are better known for their role as pests attacking crops such as corn, cotton, barley and alfalfa.

Potential new protein marker for prognosis of breast and ovarian cancer

The researchers matched tumor samples to outcomes in about 100 patients diagnosed with either breast or ovarian cancer and found that a low level of Rab25 protein on a patient's cancer sample was associated with a better clinical outcome in both cancer types.
