Genetic manipulation cuts nerve damage, boosts life span

A novel genetic manipulation significantly extends the life spans of flies by reducing the amount of wear and tear suffered by nerve cells in adults, according to new work published in Cell Metabolism. The findings support the idea that therapies designed to protect the adult nervous system by curbing the production of damaging free radicals might effectively increase longevity in other animals, including humans, the researchers said.

Paradox suggests reasons why COX-2 inhibitors hurt and help

Laboratory studies at Johns Hopkins have revealed that certain products of the enzymes COX-1 and COX-2 can both protect and damage the brain. The findings, published in the February 2005 issue of the Journal of Neurochemistry, offer tantalizing clues to why drugs like Vioxx and Celebrex, which block COX-2, can ease arthritis but potentially harm the heart and brain.

Origins of racial health disparities can involve both genes and environment and the interactions between them

New understanding of the dynamic interplay between genes and environment, made possible by technologies arising from the Human Genome Project, helps support the individualization of medicine and makes focusing on racial or ethnic group differences in disease less relevant, say Penn State researchers.
