Generation of a severe memory-deficit mutant mouse by exclusively eliminating the kinase activity of CaMKIIalpha

Ca2+/calmodulin-dependent protein kinase II alpha (CaMKII alpha) is an enzyme that adds phosphates to a variety of protein substrates to modify their functions. CaMKII alpha is enriched in the hippocampus, the memory center of the brain, and is believed to be an essential mediator of activity-dep...

Stem cell transplant in mouse embryo yields heart protection in adulthood

Rochester, Minn. May 14, 2009 - Stem cells play a role in heart muscle rejuvenation by attracting cells from the body that develop into heart muscle cells. They have been successfully used to halt or reverse cardiac injury following heart attack, but not to prevent injury before it occurs. A ...
