  • Product Description

The most common cancers of adults include lung, colon and breast carcinoma. The PP2A-A? gene (PPP2R1B) encodes a component of protein phosphatase 2A. The important role of protein phosphatase 2A in down regulating cell growth and the mutations of PP2A-A? in many human cancers suggest PP2A-A? is a tumor suppressor gene. Screening of cancer patient DNAs revealed alterations of PP2A-A? in various cancers and a germline alteration associated with breast carcinoma. Biochemical studies showed mutations in PP2A-A? reducing its ability to bind the PP2A complex. Transfecting the PP2A-A? gene into cancer cell lines conferred a relative growth disadvantage to transfected cells. Cell lines expressing exogenous PP2A-A? are found to have lower levels of ?-catenin, suggesting the PP2A-A? gene is involved in regulating the Wnt signaling pathway. These studies elucidate the tumor suppressor qualities of the PP2A-A? gene, its role in heritable cancer susceptibility, the potential it has as a target for gene directed therapy of cancer, and should be useful to professionals studying the mechanisms and treatment of cancer.
