Researchers discover inherited mutation for leukemia

...ylation. Healthy cells use this process to silence unneeded genes. But abnormal DNA methylation can turn off genes that control cell growth, and that lead to tumor growth. "Our findings identify for the first time a gene that appears to be associated with hereditary CLL," says coauthor John C. Byrd, profe...

Heart failure: Intervention possibilities from imaging programmed cell loss

... cell loss—the body's normal way of getting rid of unneeded or abnormal cells—may help in early identification of those individuals who are at risk of developing heart failure, say researchers in the April Journal of Nuclear Medicine. "Our study indicates that it is feasible to noninvasively identify cell lo...

Dying of excitement

...is deadly. To avoid this, brain cells must sop up unneeded neurotransmitters from the synapse through membrane-bound transporters. If these transporters fail, neurons and other brain cells get excited to death-- a phenomenon that may contribute to brain damage during stroke and Alzheimer's disease. Indeed,...

Bacterial protein mimics host to cripple defenses

...otential cancers in the bud, and get rid of old or unneeded cells. However, runaway PCD leads to everything fr...cells use to attach the small protein ubiquitin to unneeded or defective proteins. Other enzymes then chew up and "recycle" the ubiquitin-tagged proteins. To c...
