Objective To investigate the inhibitory effect of chelerythrine (CHE) on adenoid cystic carcinoma (ACC2) cells and its molecular mechanism. Methods CCK8, EdU, hoechst33342/PI double staining, and test kit method were used to detect the effects of CHE on ACC2 cell viability, cell proliferation, apoptosis and reactive oxygen species (ROS) level. The effects of CHE on the expression levels of Caspase-3, PARP, NF-κB, P-JNK and p-p38 were detected by Western blotting. The inhibitory effect of chelerythrine on the growth of ACC2 cells was detected by zebrafish xenograft tumor model. Results CCK-8 assay showed that: CHE can significantly inhibited the proliferation of ACC2 cells in a concentration dependent manner (P < 0.05 and 0.01) at the concentration of 2, 3, 4, 5, 6, 7, 8, 9, 10 μmol/L. The results showed that ROS in ACC2 cells was significantly increased at the concentration of 5 and 8 μmol/L (P < 0.05 and 0.01). EdU assay results showed that the proliferation of ACC2 cells was significantly decreased by CHE at the concentration of 5 and 8 μmol/L (P < 0.01). Hoechst/PI staining showed that apoptosis was significantly induced by CHE at the concentration of 5 and 8 μmol/L (P < 0.01). while N-acetylcysteine (NAC) significantly inhibited the increase of ROS and apoptosis induced by CHE (P < 0.01). Western blotting results showed that the expression of Cleaved Caspase 3, PARP and NF-κB were significantly up-regulated by 2, 5, and 8 mol/L CHE (P < 0.01), the expression of p-JNK was significantly up-regulated by 5 and 8 mol/L CHE (P < 0.01), and the protein expression of p-p38 was significantly up-regulated by 8 mol/L CHE (P < 0.01). NAC significantly decreased the expression of Cleaved Caspase 3, PARP, NF-κB, p-JNK, p-p38 protein induced by CHE (P < 0.01). CHE of 5 and 8 mol/L could effectively inhibit the growth of ACC2 cells in zebrafish (P < 0.01). Conclusion CHE can effectively inhibit the proliferation of ACC2 cells in vivo and zebrafish xenograft tumor model. Elevation of the ROS level induced by CHE, upregulation of NF-κB, p-JNK and p-p38 and then lead to the inhibition of proliferation and induction of apoptosis were involved in the inhibition of ACC2 cells in vivo and in vivo.
