Faults in p53 gene could help predict beneficial drug combination for ovarian cancer

FAULTS in a gene commonly inactivated in many different types of cancer could be used to predict which drug combination ovarian cancer patients are most likely to benefit from, according to results presented at the American Society for Clinical Oncology.

Specific forms of lymphoma create their own survival niche

Cancer cells do not grow equally well everywhere in the body. Often, they first create the conditions in which they can grow. Many years ago researchers discovered that solid tumors attract blood vessels to ensure their supply of nutrients by secreting specific factors.

Silencing two microRNAs may help treat age-related macular degeneration

Blocking two tiny molecules of RNA - a chemical cousin of DNA - appears to suppress the abnormal growth of blood vessels that occurs in degenerative eye disorders, UT Southwestern Medical Center researchers have found.

Moderate consumption of desserts with low glycemic index and glycemic load may help treat pediatric obesity

Overweight girls lose more weight and can better stay on a healthy diet if they eat sugar-free, low-fat desserts several times weekly, as opposed to any dessert once a week, a new study finds. The results will be reported Monday at The Endocrine Society's 93rd Annual Meeting in Boston.

Non-steroidal, oral contraceptive for men

Researchers at Columbia University Medical Center are honing in on the development of what may be the first non-steroidal, oral contraceptive for men. Tests of low doses of a compound that interferes with retinoic acid receptors (RARs), whose ligands are metabolites of dietary vitamin A, showed that it caused sterility in male mice.

Researchers reveal surprising link between cell's skeleton and organ size

A group of scientists at the Instituto Gulbenkian de Ci-ncia, in Portugal, have uncovered a surprising link between the cell's skeleton and organ size. The team, led by Florence Janody, show in the journal Development, that one of the proteins that regulates the skeleton of the cell also acts to blocks activation of genes that promote cell survival and proliferation.

Frog skin proteins could treat cancer, diabetes and stroke: New discovery

Scientists at Queen's University Belfast have discovered proteins in frog skins which could be used to treat cancer, diabetes, stroke and transplant patients by regulating the growth of blood vessels.

Life Technologies develops qPCR-based accurate test to detect E. coli

Life Technologies Corporation today announced that it has developed a custom test (assay) to accurately detect the E. coli bacterium that has killed at least 22 people and affected more than 2,100 worldwide, including four new cases reported in the United States. Shipments of the TaqMan® E. coli 0104 Detection Kit to test foods thought to be associated with the outbreak are now in Europe.

Senescent melanoma cells express an inflammatory secretome

Malignant melanoma is a highly aggressive and notoriously chemoresistant form of cancer. In this paper, Ohanna et al. reveal that anti-melanoma drugs may, paradoxically, induce a senescence-associated secretory profile ("secretome") that can ultimately promote metastasis and contribute to melanoma relapse.

Brown fat could help treat obesity and diabetes

A new study suggests that many adults have large amounts of brown fat, the "good" fat that burns calories to keep us warm, and that it may be possible to make even more of this tissue.

Mind-body dissonance prompts the brain to break normal cognitive boundaries

Think of the old saying, "grin and bear it." Can forcing a smile really have a positive impact on how people see the world, even to the point of becoming more open-minded? According to new research from the Kellogg School of Management at Northwestern University, the answer is yes.

Bruker to introduce unique CaptiveSpray ion source for proteomics at ASMS 2011

At ASMS 2011, Bruker is introducing the breakthrough, proprietary CaptiveSpray electrospray ion source for nano-HPLC applications in proteomics. Using CaptiveSpray technology in many cases increases bottom-up protein identifications significantly, and CaptiveSpray is presently the best available technology for robust, reproducible protein ID or quantitative proteomics applications, with excellent, stable sensitivity over long time periods

Light exposure can enhance brain's visual circuits

Any parent knows that newborns still have a lot of neurological work to do to attain fully acute vision. In a wide variety of nascent animals, genes provide them with only a rough wiring plan and then leave it to the developing nervous system to do its own finish work.

Cancer risk assessment in Lynch syndrome

Among various genetic mutations for individuals with Lynch syndrome, a hereditary cancer syndrome that carries a high risk of colon cancer and an above-normal risk of other cancers, researchers have identified mutations associated with a lower cancer risk and mutations associated with an increased risk for ovarian and endometrial cancer, according to a study in the June 8 issue of JAMA, a theme issue on cancer.
