New way to study proteins in live cells

For the first time, Johns Hopkins researchers were able to easily jumpstart the activity of a well-known cancer protein in live cells with a small molecule, a strategy that pinpointed key players in the cancer process and can be used to determine new therapeutic targets.

Genetic switch that turns off an oxygen-poor cell's combustion engine - finding has potential to limit toxic molecules

Johns Hopkins researchers have discovered a previously unrecognized role played by the gene HIF-1 as it helps cell survive when a lack of oxygen decreases production of an energy-rich molecule called ATP and increases production of toxic molecules.

Father-daughter inbreeding avoidance in a wild primate population

A 14 year behavioral and genetic study of a population of wild capuchin monkeys has shown that fathers almost never mate with their daughters, even though alpha males sire the majority of offspring produced by females unrelated to them.

ATF2 protein may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment

Researchers at Purdue University have discovered a molecular mechanism that may play a crucial role in cancer's ability to resist chemotherapy and radiation treatment and that also may be involved in Alzheimer's and heart disease.
