Gene deletion drives more than a quarter of breast cancers

A new study shows that the lack of a certain gene occurs in almost 28 percent of human breast cancers, playing a role in some 60,000 breast cancer cases in the United States and 383,000 worldwide this year.

Taking a hit or two

Cancer only arises if two or more genes are mutated. Learning which combinations of mutations cause cancer represents an extremely laborious endeavor. In the current issue of the journal Nature Methods Robert Eferl and colleagues ...

Molecular switch identified that controls key cellular process

The body has a built-in system known as autophagy, or 'self-eating,' that controls how cells live or die. Deregulation of autophagy is linked to the development of human diseases, including neural degeneration and cancer.

Protein may represent a switch to turn off B cell lymphoma

Researchers studying the molecular signals that drive a specific type of lymphoma have discovered a key biological pathway leading to this type of cancer. Cancerous cells have been described as being "addicted" to certain ...

Outwitting a brainy gene

(Medical Xpress) -- The very first in the series of mutations causing colon cancer occurs in the beta-catenin gene; this gene is abnormally activated in about 90 percent of colorectal cancer patients, and in a much smaller ...

Advanced pancreatic tumors depend on continued oncogene activity

Researchers at Dana-Farber Cancer Institute have shown that advanced pancreatic cancers in mice can't survive without continued expression of a mutant oncogene that "rewires" key metabolic pathways to fuel the cancer cells.
