Role for microRNAs in limb regeneration

In the March 15th issue of G&D, Dr. Kenneth Poss (Duke University Medical Center) and colleagues reveal that microRNA depletion is a necessary step in tissue regeneration - a discovery with interesting implications for their use in regenerative medicine.

Penn researchers identify first sex chromosome gene involved in meiosis and male infertility

A team of scientists led by University of Pennsylvania veterinary researchers have identified a gene, TEX11, located on the X chromosome, which when disrupted in mice renders the males sterile and reduces female fecundity.

How diabetes drives atherosclerosis

Researchers have discovered how diabetes, by driving inflammation and slowing blood flow, dramatically accelerates atherosclerosis, according to research to be published in the March 14 edition of the journal Circulation Research. Experts once believed that atherosclerosis, or hardening of the arteries, developed when too much cholesterol clogged arteries with fatty deposits called plaques.
