Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

The genome sequence of the parasitic amoeba Entamoeba histolytica, a leading cause of severe diarrheal disease in developing countries, includes an unexpectedly complex repertoire of sensory genes as well as a variety of bacterial-like genes that contribute to the organism's unique biology. The report, which appears in the February 24 issue of Nature, presents the first genome-wide study...

An HIV Protein Plays a Surprising Role in Gene Activation

Retroviruses are expert manipulators when it comes to co-opting their host's cellular resources. A great deal of human complexity stems from the vast repertoire of proteins and mechanisms dedicated to the business of regulating gene expression, and retroviruses like HIV have evolved myriad ways of redirecting that machinery to their own benefit. Humans and other eukaryotes have three type...

But while most of those surveyed felt it personally important to help support HIV vaccine research, a majority expressed reluctance to support a friend or family member’s participation in an HIV vaccine clinical trial.<...

A surprising pair of proteins help make healthy eggs

Human eggs rely on handmaidens. Called granulosa cells, they surround eggs and deliver nutrients and hormones. Without granulosa cells, eggs cannot mature and be successfully fertilized. How do these handmaidens grow? Biologists at Brown University and the University of California–Berkeley have discovered that two proteins ?TAF4b and c-Jun ?team up to turn on about two dozen genes inside t...
