Gene that drives cells to commit suicide also plays key role in development of skeletal muscle
... responds to hostile environments by stimulating a cascade of biochemical reactions that executes a process called programmed cell death, or apoptosis. But this activity is blocked when an enzyme called Akt attaches a phosphate molecule to each of three sites on FKHR. Phosphate is a molecule made up of a pho...Rockefeller scientists identify 'natural' proteins that push stem cells to produce hair, not skin
...nscription factor. Then, the Wnt protein prompts a cascade of signals that turn off the machinery that degrades excess beta-catenin. This allows beta-catenin proteins to build up inside the stem cell. This excess beta-catenin binds to Lef-1. Once in the nucleus of the stem cell, the beta-catenin/Lef-1 compl...Underwater sensor system could protect reservoirs, drinking water
... and then broadcast to even more distant nodes. A cascade of parent nodes eventually covers the entire system. Periodically, the network sends data through the system. Each node sends its sensor data to its parent node. That node sends the received data and its own data to its parent node until all the d...Study of insecticide neurotoxicity yields clues to onset of Parkinson's Disease
