Figure 3From: TFPI-2 is a putative tumor suppressor gene frequently inactivated by promoter hypermethylation in nasopharyngeal carcinoma Methylation-specific PCR analysis of the TFPI-2 promoter region in NPC primary tumors and normal nasopharyngeal epithelia (NNE). Four NPC primary tumors (NPC 13, 16, 24 and 34) and 4 NNE (NNE3, 7, 9 and 12) are shown as examples. U: unmethylated alleles; M: methylated alleles. The data are representative of 2 independent experiments.Back to article page
