Deregulation of 2 Potassium Channels in Pancreas Adenocarcinomas

Abstract

This is the first report of deregulation of 2 K channels in pancreatic adenocarcinoma. GIRK1 was highly expressed in pancreatic adenocarcinomas, corresponding to its role in cell proliferation. Methylation of KV1.3 gene promoter could explain the decrease of KV1.3 expression in adenocarcinomas. New therapeutic agents, such as DNA methylation inhibitors, could be useful against this dramatic cancer.
