MW-19, a dihydropyrazole derivative, induces human triple-negative breast cancer cell apoptosis by targeting apoptosis-related pathways
Previous studies have indicated that heterocyclic substituted dihydropyrazole derivatives, particularly MW-19, potentially exert anticancer activity in vitro; however, the underlying mechanism remains unknown. The present study was designed to investigate the mechanisms underlying MW-19 activity in triple-negative breast cancer cells. A sulforhodamine B assay was performed to evaluate cell proliferation inhibition rates, and the antitumor effect of MW-19 was evaluated in mice with HCC-1806 xenografts. Apoptosis was analyzed by Hoechst 33342 and annexin V/propidium iodide staining. Expression of pro- and antiapoptotic proteins and mRNA were analyzed by western blotting and reverse transcription-quantitative (RT-q) PCR, respectively. We found that MW-19 significantly inhibited HCC-1806 cell proliferation in a dose- and time-dependent manner, and significantly inhibited MDA-MB-231 cell migration. Importantly, oral administration of MW-19 significantly inhibited HCC-1806 tumor growth in BALB/c-nu/nu mice. Moreover, MW-19 treatment induced marked apoptosis and G2/M arrest in the sensitive cell line, HCC-1806. RT-qPCR analysis showed that levels of proapoptotic genes (Bax, caspase-3, caspase-7, and Fas) were considerably increased in the MW-19 group relative to the control group, while those of antiapoptotic factors (Bcl-2, C-MYC) were dramatically decreased. Consistently, Bax, caspase-3, and caspase-7 were significantly induced after MW-19 treatment, while levels of phosphorylated (p-)AKT, p-PI3K, p-ERK, and the antiapoptotic protein, Bcl-2, were clearly diminished, and the P38 MAPK signaling pathway was activated. Furthermore, P38 pharmacological inhibitors abrogated MW-19-induced apoptosis. Together, our findings indicate that MW-19 exerts antitumor effects by targeting PI3K/AKT and ERK/P38 signaling pathways.
