The ABCC4 gene is a promising target for pancreatic cancer therapy

Abstract Pancreatic cancer is a malignant neoplasm of the pancreas that usually has a poor prognosis. The investigation of targets that effectively inhibit pancreatic cancer cell proliferation should provide a fundamental basis for the clinical application of gene therapy. Here, high expression levels of ABCC4 protein in thirty-six pancreatic cancer specimens were quantified using an immunohistochemical assay, and the potential of ABCC4 as a therapeutic target for pancreatic cancer was investigated. Inhibition of ABCC4 expression at the mRNA and protein levels was achieved in Panc-1 and BxPC-3 pancreatic cancer cells infected with a lentivirus expressing an ABCC4 short hairpin RNA (shRNA). The downregulation of ABCC4 expression in Panc-1 and BxPC-3 cells significantly inhibited their proliferation and colony formation in vitro, compared to cells infected with mock control ( p
