Figure 5From: TFPI-2 is a putative tumor suppressor gene frequently inactivated by promoter hypermethylation in nasopharyngeal carcinoma Treatment with 5-aza-dC restores TFPI-2 expression in 3 NPC cell lines. TFPI-2 mRNA expression level was evaluated by RT-PCR. GAPDH was amplified as an internal control. NNE8 was used as positive control. A water blank control was also included.Back to article page
