Abstract:
OBJECTIVETo explore the effect of quercetin on the invasion, migration, proliferation and cell cycle of glioma U87 cells.
METHODSGlioma U87 cells were treated with 50, 100, or 150 µmol/L quercetin (Q(50), Q(100) and Q(150) groups, respectively) or with DMSO (Q(0) group). Transwell in vitro invasion and migration assays, Click-iT Edu test and flow cytometry were performed to evaluate the effect of quercetin on the invasion, migration, proliferation and cell cycle of U87 cells.
RESULTSAfter 36 h of quercetin treatment, the cells in Q(50), Q(100) and Q(150) groups showed invasive cell percentages (relative to Q(0) group) of 52.08%, 24.63%, and 13.13%, respectively (P<0.05). After quercetin treatment for 12 h, the migrating cell percentages (relative to Q(0) group) in Q(50), Q(100) and Q(150) groups were 49.46%, 26.78%, and 14.56%, respectively (P<0.05). After 24 h of quercetin treatment, the cell proliferation ratios in Q(0), Q(50), Q(100) and Q(150) groups were 25.21%, 18.38%, 16.74% and 15.24%; the cell percentages in phase G0/Gl were 71.14%, 72.71%, 69.29%, and 66.47%, phase S were 25.32%, 22.48%, 21.96%, and 23.32%, and phase G(2)/M were 3.53%, 4.80%, 8.75%, and 10.25% in the 4 groups, respectively, showing a significant difference between groups Q(100), Q(150) and group Q(0) in phase G(2)/M cell percentages (P<0.05).
CONCLUSIONSQuercetin can significantly inhibit the invasion, migration and proliferation of glioma U87 cells by blocking the cell cycle progression.
