Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer
...teristic of more complex organisms. For example, a family
of membrane receptors appears to be one of the mechanisms by which the parasite senses the presence of its human host and translates environmental cues into signaling events, which are processed by the parasite. Another unusual feature of the g...
Newly-discovered class of genes determines and restricts stem cell fate

of genes--they can both determine the cell type, but also put the breaks on differentiation," says Epstein. "We have named them pangenes, after the Greek god Pan and Peter Pan, who were able to orchestrate complex events while never growing old." Eps...

of enzymes that oxidize drugs, steroids, and carcinogens. Oxidation of these potentially harmful substances makes them more water-soluble and easier to clear out of cells. The P450s are also involved in vascular autoregulation, particularly in the br...
Researchers identify gene that plays major role in age-related blindness disease
