BCL2 and ovarian carcinoma: To examine whether mRNA levels of BCL2 family proteins could be a predictive marker for ovarian cancer treatment efficacy, ovarian cancer patient data from gene expression profiling interactive analysis (GEPIA) and Kmplot (Kaplan Meier Plot) databases were obtained, and overall survival was analyzed between groups with high expression versus low expression of each BCL2 family member at the mRNA level.
