Three is the magic number: A chain reaction required to prevent tumor formation
Protein p53 is known for controlling the life and death of a cell and has a key role in cancer research. P53 is known to be inactive in 50 percent of cancer patients. If researchers succeed in re-establishing the presence ...

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 ...

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 ...

Cancer cells and stem cells share same origin: study
Oncogenes are generally thought to be genes that, when mutated, change healthy cells into cancerous tumor cells. Scientists at the Keck School of Medicine of the University of Southern California (USC) have proven that those ...

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 ...

The genome guardian's dimmer switch: Regulating p53 is a matter of life or death
Scientists at the Salk Institute for Biological Studies have found clues to the functioning of an important damage response protein in cells. The protein, p53, can cause cells to stop dividing or even to commit suicide when ...

8 hours of resistance: Why do cancer cells easily give in to the temptation to divide?
Temptations to exceed the speed limit are always plentiful, but only reckless drivers give in to such impulses. Likewise, numerous growth factors always abound in our bodies, but only cancerous cells are quickly "tempted" ...

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.
