Decreased lung tumorigenesis in mice genetically deficient in cytosolic phospholipase A2.

abstract：:Many chemoradiation therapies cause DNA damage through oxidative stress. An important cellular mechanism that protects cells against oxidative stress involves DNA repair. One of the primary DNA repair mechanisms for oxidative DNA damage is base excision repair (BER). BER involves the tightly coordinated function of fo...
