A tumor suppressor gene inhibits one or more function(s) required for malignant transformation, including self-sufficiency in growth signals, insensitivity to antigrowth signals, evasion of apoptosis, limitless replicative potential, and tissue invasion and metastasis or sustained angiogenesis. 1 Some tumor suppressor genes are lost in the germ line, whereas the function of other tumor suppressor genes is lost through somatic change. At present, loss of function has been described for some 16 putative tumor suppressor genes in epithelial ovarian cancer (Table 5.1). During oncogenesis, loss of tumor suppressor gene function can occur through deletion, mutation, or epigenetic silencing. Loss of heterozygosity has been observed in 11 putative tumor suppressors, inactivating mutations in four of these genes ( p53, PTEN, BRCA1, and BRCA2), and promoter methylation and silencing in eight. In each case, only a fraction of ovarian cancers from different patients lose the function...
