Alternating rise and fall of SCF - NIPA levels act as switch regulating cell division
Cells control mitosis (cell division) by assembling a biochemical switch to block it or by disassembling the switch to trigger it, according to investigators at St. Jude Children's Research Hospital and the Technical University of Munich.... The researchers found that when the switch called SCFNIPA is intact, levels of an enzyme called cyclin B1 drop, preventing the enzyme from activating a third...Working independently, two research teams funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), have identified how Nipah and Hendra viruses, closely related viruses first identified in the mid-1990s, gain entry into human and animal cells....... Nipah and Hendra are emerging viruses that cause serious respiratory and neurolo...
