Evasion of apoptosis is a feature of cancer cells. As a mechanism of apoptosis inactivation in cancer cells, somatic mutations of pro-apoptotic genes have been reported in many cancers. Caspase-10 is an initiation-phase caspase, and somatic mutation of CASP10 that encodes caspase-10 has been found in non-Hodgkin's lymphoma and gastric carcinoma. ⋯ Our data indicate that somatic mutation of CASP10 is rare in colon, breast, lung, and hepatocellular carcinomas. However, the data also suggest that CASP10 mutation might contribute to the pathogenesis of some colon carcinomas together with other CASP gene mutations.
