A protein called CDC7, long thought to play an essential role early in the cell division process, is in fact replaceable by another protein called CDK1, according to a study by investigators at Weill Cornell Medicine and the Dana Farber Cancer Institute. The finding represents a fundamental advance in cell biology and may lead to new cancer therapies...

Novel study documents marked slowdown of cell division rates in old age
Clearer understanding of lower cell replication rates in old age may have implications for preventing cancer and slowing aging JOHNS HOPKINS MEDICINE In a novel study comparing healthy cells from people in their 20s with cells from people in their 80s, researchers at the Johns Hopkins Kimmel Cancer Center say they have documented that cell...

Better together: Mitochondrial fusion supports cell division
Mitochondria are the powerhouses of the cell. And for mitochondria, much like for double-header engines stacked together in a steam train, working in multiples has its benefits. New research from Washington University in St. Louis shows that when cells divide rapidly, their mitochondria are fused together. In this configuration, the cell is able to more...
