Functional regulatory variants of MCL1 contribute to enhanced promoter activity and reduced risk of lung cancer in nonsmokers: implications for context-dependent phenotype of an antiapoptotic and antiproliferative gene in solid tumor.

Abstract excerpt

BACKGROUND: Dysfunction of molecules that regulate both apoptosis and proliferation is involved in tumorigenesis. A common insertional polymorphism in promoter of MCL1, a member of BCL2 family gene with the dual regulatory functions, has been shown to be functional in leukemia, but its association with cancer predisposition and prognosis has not been well established. We hypothesized that MCL1 promoter variants...
