A better 'mousetrap' discovered in fruit flies might stop a human cancer-driving kinase in its tracks A seemingly obscure gene in the female fruit fly that is only active in cells that will become eggs has led researchers at the Stowers Institute for Medical Research to the discovery of a atypical protein that lures, traps, and inactivates the powerful Polo kinase, widely considered the master regulator of cell division. Its human homolog, Polo-like kinase-1 (Plk1), is misregulated in many...

[ Watch the Video ] After more than a century of study, mysteries still remain about the process of meiosis—a special type of cell division that helps insure genetic diversity in sexually-reproducing organisms. Now, researchers at Stowers Institute for Medical Research shed light on an early and critical step in meiosis. The research, to be published in the Nov. 8, 2011 issue of Current Biology, clarifies the role of key chromosomal regions called centromeres in the formation of a...
