Figure 1 Methylation-specific polymerase chain reaction analyses of retinoblastoma protein-interacting zinc finger 1 promoter methylation status using genomic DNA extracted from 6 human esophageal squamous cell carcinoma cell lines, products of 177 bp and 175 bp were expected for methylated (M) and unmethylated (U) DNA. M: Methylation-specific amplification (177 bp); U: Unmethylation-specific amplification (175 bp).
