Representative examples of MSP analysis of DST, FLT3, PTCH2 and TIAM1 in 8 HCC cell lines. DNA extracted from 8 HCC cell lines were amplified with primers specific to the methylated (M) or unmethylated (UM) CpG islands of each gene after modification with sodium bisulfite. +, positive control; DW, distilled water. Positive controls for methylated MSP and unmethylated DNA are M.SssI-treated placental DNA and whole-genome amplified DNA, respectively.
