Ivermectin inhibited ovarian cancer cells proliferation in vitro. a Cell viability was measured by the CCK8 assay in IOSE80, SKOV3, and TOV-21G cells treated with the different concentrations of ivermectin for 24 h (n = 3, X = Log (ivermectin concentration)). b CCK8 cell proliferation test on SKOV3 (n = 3). c CCK8 cell proliferation test on TOV-21G (n = 3). d EdU cell proliferation test on SKOV3. e EdU cell proliferation test on TOV-21G. f Histogram statistics of EdU cell proliferation test on SKOV3 and TOV-21G (n = 3). g Clonogenic survival test on SKOV3 and TOV-21G. h Histogram statistics of clonogenic survival test on SKOV3 and TOV-21G (n = 3). *p < 0.05, **p < 0.01, ***p < 0.001
