apoptosis

Apoptosis and necrosis are considered to be distinct modes of cell death; however, apoptosis can progress to secondary necrosis if apoptotic cells are not efficiently removed by phagocytic cells. Secondary necrosis was thought to be unregulated and to occur through passive cell swelling. However, research shows that...

In the years since the discovery of RNA interference, researchers have found that this process is far more widespread than we might expect, and that small pieces of RNA play many functional roles. Small (or short) interfering RNA (siRNA) is the most commonly used RNA interference (RNAi) tool for inducing short-term ...
