Protein found to shield pancreatic cancer cells from self-destruction

An overexpressed protein protects human pancreatic cancer cells from being forced to devour themselves, removing one of the body's natural defenses against out-of-control cell growth, researchers at The University of Texas M. D. Anderson Cancer Center report in the March issue of Molecular Cancer Research.

The protein tissue transglutaminase, known by the abbreviation TG2, previously has been found by researchers at M. D. Anderson and elsewhere to be overexpressed in a variety of drug-resistant cancer cells and in cancer that has spread from its original organ (metastasized).

"In general, you rarely see overexpression of TG2 in a normal cell," says Kapil Mehta, Ph.D., professor in the M. D. Anderson Department of Experimental Therapeutics, who began 10 years ago studying TG2 as an inflammatory protein.
