Targeting developmental regulators of zebrafish exocrine pancreas as a therapeutic approach in human pancreatic cancer.

ABSTRACT: Histone deacetylases (HDACs) and RNA polymerase III (POLR3) play vital roles in fundamental cellular processes, and deregulation of these enzymes has been implicated in malignant transformation. Hdacs and Polr3 are required for exocrine pancreatic epithelial proliferation during morphogenesis in zebrafish. We aim to test the hypothesis that Hdacs and Polr3 cooperatively control exocrine pancreatic growth, and combined inhibition of HDACs and POLR3 produces enhanced growth suppression in pancreatic cancer. In zebrafish larvae, combination of a Hdac inhibitor (Trichostatin A) and an inhibitor of Polr3 (ML-60218) synergistically prohibited the expansion of exocrine pancreas. In human pancreatic adenocarcinoma cells, combination of the HDAC inhibitor suberoylanilide hydroxamic acid (SAHA) and
