A chaperone for the 'guardian of the genome'

The protein p53 plays an essential role in the prevention of cancer by initiating the controlled death of a cell with damaged genes which is in danger to transform into a cancerous cell. The heat shock protein Hsp90, in turn, ...

Novel compound selectively kills cancer cells

A cancer cell may seem out of control, growing wildly and breaking all the rules of orderly cell life and death. But amid the seeming chaos there is a balance between a cancer cell's revved-up metabolism and skyrocketing ...

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. ...

Eggs' quality control mechanism explained

To protect the health of future generations, body keeps a careful watch on its precious and limited supply of eggs. That's done through a key quality control process in oocytes (the immature eggs), which ensures elimination ...

Genetic abnormalities identified in pluripotent stem cell lines

A multinational team of researchers led by stem cell scientists at the University of California, San Diego School of Medicine and Scripps Research Institute has documented specific genetic abnormalities that occur in human ...

'Mahjong' gene is key player when cancer, normal cells compete

A landmark study by Florida State University biologists, in collaboration with scientists in Britain, is the first to identify a life-or-death "cell competition" process in mammalian tissue that suppresses cancer by causing ...

Study finds key protein controls T-cell proliferation

New research has identified that a key protein called PEA-15 stops T-cell proliferation by blocking the cell's ability to reproduce. The control of T-cell proliferation is essential in preventing certain blood cancers and ...
