Abstract
PURPOSE: Pancreatic cancer is a highly malignant disease with an extremely poor prognosis. The benefit of chemotherapy treatment for pancreatic cancer is very limited. Therefore, new therapeutic targets and approaches are urgently needed for this deadly disease. Multi-target therapy is a potential and feasible treatment strategy. Given the important roles that histone deacetylases (HDACs) and phosphoinositide-3-kinase (PI3K) play in pancreatic cancer, we investigated the antitumor activity and mechanism of novel HDAC and PI3K dual inhibitor CUDC-907 in pancreatic cancer. METHODS AND RESULTS: MTT assay and flow cytometric analysis were used to examine the in vitro antitumor activity of CUDC-907. A BxPC-3-derived xenograft mouse model was used to determine CUDC-907 in vivo efficacy. The TUNEL assay as used to determine apoptosis in tumors in vivo post CUDC-907 treatment. Western blots were used to determine the effect of CUDC-907 on protein levels. Our results show that CUDC-907 decreased viable cells and induced cell death in a concentration-dependent manner. Furthermore, CUDC-907 showed promising in vivo antitumor activity in the BxPC-3-derived xenograft mouse model while exhibiting tolerable toxicity. Furthermore, long-term treatment with CUDC-907 induced phosphorylation of AKT, S6 (ribosomal protein S6), and ERK (extracellular regulated protein kinase), and inhibition of PI3K (phosphatidylinositol 3-kinase), mTOR (mammalian target of rapamycin), or ERK significantly enhanced CUDC-907-induced cell death in pancreatic cell lines. CONCLUSION: Taken together, these findings support the clinical development of CUDC-907 for the treatment of pancreatic cancer and identify compensatory activation of mTOR and MEK/ERK as a possible mechanism of resistance to CUDC-907.
