Researchers find new role for cancer protein p53

The gene for the protein p53 is the most frequently mutated in human cancer. It encodes a tumor suppressor, and traditionally researchers have assumed that it acts primarily as a regulator of how genes are made into proteins. ...

Protein and microRNA block cellular transition vital to metastasis

Like a bounty hunter returning escapees to custody, a cancer-fighting gene converts organ cells that change into highly mobile stem cells back to their original, stationary state, researchers report online at Nature Cell ...

Advances reported in quest for drugs targeting childhood cancer

Investigators believe they have identified the founding member of a chemical family they hope will lead to a new class of cancer drugs, the first designed specifically against a childhood tumor, according to research led ...

Toward new drugs that turn genes on and off

Scientists in Michigan and California are reporting an advance toward development of a new generation of drugs that treat disease by orchestrating how genes in the body produce proteins involved in arthritis, cancer and a ...

MicroRNA undermines tumor suppression

A small piece of RNA, or microRNA (miRNA), ratchets down the activity of the tumor-suppressor gene p53, according to a study by Whitehead Institute and National University of Singapore researchers.
