Abstract: PURPOSE : To observe the effect of quercetin on human adenoid cystic carcinoma cells (ACC-M) proliferation and apoptosis. METHODS : CCK-8 staining was used to detect different concentrations of quercetin on ACC-M cell proliferation inhibition, the inhibition rate and IC50 were calculated; flow cytometry was used to detect ACC-M cell apoptosis rate and cell cycle distribution; Survivin mRNA of ACC-M cells was detected by RT-PCR. The difference between each group was analyzed with SPSS20.0 software package. RESULTS : Quercetin inhibited ACC-M cell growth obviously in a concentration dependent manner. The IC50 was 151.12 μmol/L (P<0.05); annexin V/PI double staining assay showed that quercetin can induce apoptosis of ACC-M cells in a dose and time dependent manner (P<0.05); PI staining assay showed that quercetin played an important role in G2/M cells, which were specifically arrested in G2/M phase. RT-PCR showed the quercetin concentration was negatively related with survivin mRNA in ACC-M cells and 200 μmol/L quercetin could inhibit the expression of Survivin mRNA significantly. CONCLUSION S: Quercetin can inhibit the proliferation of ACC-M cells and induce its apoptosis in a time and dose dependent manner by down-regulating the level of Survivin.
