RT-PCR analysis (Fig. 1B) and western blot (Fig. 1C) revealed that both mRNA and protein HERG1 expression were markedly higher in pancreatic cancer cell lines PANC-1, SW1990, CFPAC-1, and BxPC-3 compared to the average HERG1 expression in normal tissues adjacent to the analyzed tumors. This evidence concerns the gene KCNH2 and familial pancreatic carcinoma.
