Cholangiocarcinoma (CCA), also known as biliary tract cancer, is a heterogeneous group of malignancies formed by the differentiation of epithelial cells in the biliary tract. CCA is the second most common primary liver tumor and it has both an increasing rate and high mortality worldwide with its late diagnosis, refractory type, and aggressiveness. The effects of autophagy modulators and HDAC inhibitors in CCA are not fully known. This study is proposed a novel treatment approach with the combinational therapy of autophagy and HDAC inhibitors for CCA patients. In results obtained with alone HDACis, alone autophagy modulators, and combinations of HDACis and autophagy modulators, Nocodazole from autophagy modulators and MS-275 and Romidepsin from HDAC inhibitors showed a better synergistic effect on the TFK-1 and EGI-1 cell lines of the cholangiocarcinoma. In cell cycle analysis of the combination, was achieved arrest at the S phase and G2/M phase. In conclusion, this study highlights the important combination of HDAC inhibitors and autophagy modulators, which is a promising therapy in CCA.
