DAPK1 and cervical carcinoma: For this study, we selected a set of 10 TSGs (APC, CCNA, CDH1, CDH13, DAPK1, FHIT, RARB, SLIT2, TIMP3, and WIF1) that, based on a survey of the literature, had previously been shown to be targets for aberrant DNA methylation in cervical cancer but not comprehensively tested using quantitative methods.
