Oncologists welcome gene expression profiling tests for women with early-stage breast cancer but have concerns

Oncologists welcome gene expression profiling tests as an added tool in deciding whether women with early-stage breast cancer should have chemotherapy, a new study has found. But they have significant reservations about the cost of the test and whether it is being overused and used for the right patients.

Rare, aggressive subtype of pediatric acute lymphoblastic leukemia has surprisingly few mutations

The St. Jude Children's Research Hospital--Washington University Pediatric Cancer Genome Project reports that a highly aggressive form of leukemia in infants has surprisingly few mutations beyond the chromosomal rearrangement that affects the MLL gene. The findings suggest that targeting the alteration is likely the key to improved survival.

Unregulated Internet marketing of cancer-related gene tests poses challenges for consumers, physicians

Websites that market personalized cancer care services often overemphasize their purported benefits and downplay their limitations, and many sites offer genetic tests whose value for guiding cancer treatment has not been shown to be clinically useful, according to a new study from Dana-Farber Cancer Institute.

Severe mortality-associated diseases less prevalent in members of long-lived families

Recent research from the Long Life Family Study (LLFS) confirms that severe mortality-associated diseases are less prevalent in the families of long-lived individuals than in the general population. The Journals of Gerontology, Series A will publish these findings in the article titled, "Are Members of Long-Lived Families Healthier than Their Equally Long-Lived Peers? Evidence from the Long Life Family Study" on March 5, 2015.

Anthropology researchers find skeletal variation in pre-Columbian South America

A team of anthropology researchers has found significant differences in facial features between all seven pre-Columbian peoples they evaluated from what is now Peru - disproving a longstanding perception that these groups were physically homogenous. The finding may lead scholars to revisit any hypotheses about human migration patterns that rested on the idea that there was little skeletal variation in pre-Columbian South America.

Consuming popular dietary supplement ubiquinone unlikely to provide any benefit

The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study by scientists at McGill University finds that ubiquinone is not a crucial antioxidant -- and that consuming it is unlikely to provide any benefit.

Researchers present new findings about 'key players' involved in brain inflammation

Inflammatory processes occur in the brain in conjunction with stroke and neurological diseases such as Alzheimer's and Parkinson's disease. Researchers from Lund University and Karolinska Institutet in Sweden, in close cooperation with a group led by Professor José L. Venero at the University of Seville, have presented new findings about some of the 'key players' in inflammation.
