Researchers identify potential molecular target to prevent growth of cancer cells
Researchers have shown for the first time that the protein fortilin promotes growth of cancer cells by binding to and rendering inert protein p53, a known tumor suppressor. This finding by researchers at the University of ...

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 link between DNA damage and immune response
Researchers offer the first evidence that DNA damage can lead to the regulation of inflammatory responses, the body's reaction to injury. The proteins involved in the regulation help protect the body from infection.

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 ...

Cancer cell survival is not 'miR-ly' dependent on p53
Squamous cell carcinoma (SCC) is a common type of skin cancer. In this paper, Leif Ellisen and colleagues at Mass General Hospital investigated the p53-related proteins p63 and p73 in SCC cells, and discovered a feedback ...
