NQO1/CPT1A promotes the progression of pancreatic adenocarcinoma via fatty acid oxidation.

ABSTRACT: NQO1, a cytosolic enzyme, is closely related to the progression of cancers and poor outcome of cancer patients. However, the molecular biological mechanism of NQO1 tumorigenicity in pancreatic adenocarcinoma (PAAD) has not been clearly understood. In this study, we demonstrate the molecular mechanism of NQO1 in PAAD proliferation, metastasis and fatty acid oxidation (FAO). Multiple databases and western blot analysis show that NQO1 is overexpressed in PAAD and associated with lymph node metastasis and shorter survival. Furthermore, in vitro and in vivo experiments reveal that overexpression of NQO1 improves tumor growth, metastasis and FAO in PAAD. Mechanistically, NQO1 is able to bind to carnitine palmitoyltransferase 1A (CPT1A), a key enzyme controlling FAO. Therefore, Co-I
