Wip1 could be new target for cancer treatment

Researchers have uncovered mutations in the phosphatase Wip1 that enable cancer cells to foil the tumor suppressor p53, according to a study in The Journal of Cell Biology. The results could provide a new ...

Deficiency in p53 anti-tumor protein delays DNA repair after radiation

Researchers at Moffitt Cancer Center have found that a deficiency in an important anti-tumor protein, p53, can slow or delay DNA repair after radiation treatment. They suggest that this is because p53 regulates the expression ...

Study finds key to calling back-up help when tumor-fighter p53 goes down

Tumor suppression, the family business of the sibling genes p53, p63 and p73, is undermined from within by the split personalities of p63 and p73, which each produce protein forms that not only block the work of the other ...

Scientists find new role for P53 genetic mutation -- initiation of prostate cancer

A team of UC Davis investigators has found that a genetic mutation may play an important role in the development of prostate cancer. The mutation of the so-called p53 (or Tp53) gene was previously implicated in late disease ...

Elimination of two ribosome subunits activates cell cycle control

Alterations in the formation of ribosomes (the elements of the cell where proteins are made) cause the induction of p53 protein and cell cycle disruption. This process is crucial to understand fundamental biological processes ...

Drug kills cancer cells by restoring faulty tumor suppressor

A new study describes a compound that selectively kills cancer cells by restoring the structure and function of one of the most commonly mutated proteins in human cancer, the "tumor suppressor" p53. The research, published ...

DGK-alpha helps cancer cells gain traction and mobilize

Metastasizing cancer cells often express integrins that provide better traction. A new study in The Journal of Cell Biology reveals how a lipid-converting enzyme helps the cells mobilize these integrins.

Gene found to play role in early cancer

(Medical Xpress) -- Mutations to a gene called p53 have been linked to half of all cancers, leading to tumor growth and the spread of cancerous cells. Now, a Cornell-led study identifies for the first time the mechanisms ...
