DCAF15 knockdown eliminates the inhibitory effect of indisulam on the migration of gastric cancer cells.A and B, scratch assay was performed for shNC and shDCAF15-expressing AGS and MGC803 cells in the presence of dimethyl sulfoxide (DMSO) or indisulam (10 μM). Representative images were taken at 0 h and 48 h after treatment. Vertical yellow lines indicated the edge of the scratch. Mean ± SD (n = 12 or 10 from three biological replicates), Student’s t test, ∗∗∗p < 0.001, ∗∗∗∗p < 0.0001, ns: not significant. The scale bar represents 200 μm.
