...ng Akt to contribute to tumor growth. "When a cell loses PTEN through, say, a mutation, Akt goes gangbusters," says Sabatini. The exact means by which Akt switches on when it reaches the cell membrane has only been partially understood.

...e, it is not methylated. If, on the other hand, it loses at least 30 percent of its intensity, it is regarded as methylated. In the study, the research team tested 2447 fragments in each animal. They found anywhere from 45 to 209 (.8 percent to 8.5 percent) of the fragments methylated in the mice with can...Researchers discover a good side to cholesterol in controlling cell signals
... ERK. When lipid domain cholesterol gets low, OSBP loses its cholesterol and no longer is able to bind the enzymes that deactivate ERK, keeping it active.

To determine the extent to which ARLTS1 appears in various populations, researchers compared tumor tissue or blood samples from 325 patients with different forms of familial or sp...Discovery at UCSB may lead to new drugs to treat cancer, control fertility

This same loss has been linked to head and neck, esophageal, colorectal, breast and cervical cancers as well.
