Cancer biology: Keeping bad company
The p53 tumor suppressor protein manages DNA repair mechanisms in response to genetic damage and kills off precancerous cells before they multiply. The loss of p53 due to mutation greatly increases risk of ...

New technique catalogs lymphoma-linked genetic variations
(Medical Xpress)—As anyone familiar with the X-Men knows, mutants can be either very good or very bad—or somewhere in between. The same appears true within cancer cells, which may harbor hundreds of mutations that set ...

A study of fruit fly genes reveals how molecules cooperate to induce tumor formation
Cancer biologists have known for decades that even the most potent cancer-causing genes do not act alone. Yet, identifying which combinations of genetic changes can cause a tumor to form and disease to progress ...

COUP-TFII sparks prostate cancer progression
Prostate cancer presents a dilemma for patients and the physicians who treat them. Which cancers are essentially indolent and present no risk and which are life threatening? Which can be watched and which need aggressive ...
