Meth-DOP-PCR in serum DNA. (a) Methylation analysis of MGMT, RASSF1A, DCR2 and CDKN2A gene promoter sequences determined by Meth-DOP-PCR in the circulating DNA from four lung cancers patients. (b) Comparison between Meth-DOP-PCR and MSP for the analysis of the methylation status of the RASSF1A gene in 12 serum samples from lung cancer patients.
