ppENK Gene Methylation Status in the Development of Pancreatic Carcinoma

Figure 2

RT-PCR analysis of 5 pancreatic carcinoma cell lines. The ppENK PCR band is 179 bp. Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) serves as an RNA control: lane 1, normal pancreatic tissue (frozen tissue); lane 2, Panc-1; lane 3, Pupan-1; lane 4, SW1990; lane 5, PC3; lane 1, Aspc-1.
