A body of evidence suggests that many molecular alterations occur during ovarian carcinogenesis, of which the activated Notch, Wnt and STAT3 signaling pathways are supposed to play active roles in the carcinogenic process by up-regulating the expression of some tumor promoting genes such as c-Myc, survivin and Bcl-2 [46,47]. This evidence concerns the gene STAT3 and neoplasm.
