PRDM5 and cervical carcinoma: Methylation-specific PCR (MSP) results showed that PRDM5 was frequently methylated in silenced cell lines, including 80% (4/5) nasopharyngeal, 44% (8/18) esophageal, 76% (13/17) gastric, 25% (3/12) hepatocellular, and 50% (2/4) cervical carcinoma cell lines (Figure 2, Table 1), with the exception of only infrequent PRDM5 methylation detected in lung, colon, ovarian and bladder cancer cell lines (Figure S1).
