Abstract
KHC-4 is a 2-phenyl-4-quinolone analogue that exhibits anticancer activity. Aberrant activation of β-catenin signaling contributes to prostate cancer development and progression. Therefore, targeting β-catenin expression could be a useful approach to treating prostate cancer. We found that KHC-4 can inhibit β-catenin expression and its signaling pathway in DU145 prostate cancer cells. Treatment with KHC-4 decreased total β-catenin expression and concomitantly decreased β-catenin levels in both the cytoplasm and nucleus of cells. KHC-4 treatment also inhibited β-catenin expression and that of its target proteins, PI3K, AKT, GSK3β and TBX3. We monitored the stability of β-catenin with the proteasomal inhibitor, MG132, in DU145 cells and found that MG132 reversed KHC-4-induced proteasomal β-catenin degradation. We verified CDK1/β-catenin expression in KHC-4 treated DU145 cells. We found that roscovitine treatment reversed cell proliferation by arresting the cell cycle at the G2/M phase and β-catenin expression caused by KHC-4 treatment. We suggest that KHC-4 inhibits β-catenin signaling in DU145 prostate cancer cells.

Abstract
In this study, the antitumor activity of KHC-4 was analyzed using human prostate cancer (CaP) cells and the underlining anticancer mechanisms of KHC-4 were identified. KHC-4 inhibited cell proliferation and induced cytotoxicity in the castration-resistant CaP DU145 cell line. The most effective concentration of KHC-4 was 0.1 μM. Cell cycle analysis demonstrated that KHC-4 treatment caused G2/M arrest and a subsequent increase in the sub-G1 population. Furthermore, KHC-4 is up-regulated p21, p27, and p53 in a time- and concentration-dependent manner. The exposure of cells to KHC-4 induced Cdk1/cyclin B1 complex activity, which led to cell cycle arrest. Moreover, KHC-4 inhibited the activities of MMP-2 and MMP-9 to inhibit tumor cell metastasis. © 2015 Wiley Periodicals, Inc. Environ Toxicol 31: 1879-1887, 2016.
