Fig. 4. (a) Results of the CCK-8 assay of MDA-MB-231 cells incubated with Rh-T, Nph-A, and Nph-A/Rh-T (1 : 1) at various concentrations (0 μM, 6.25 μM, 12.5 μM, 25 μM, and 50 μM). (b) Results of the scratch wound healing assays of MDA-MB-231 cells with Rh-T (12.5 μM), Nph-A (12.5 μM), and Nph-A/Rh-T (1 : 1, 12.5 μM) with and without cilengitide (Cil, 40 μM). (c) Quantification of the migration rates of cells (%). ns ≥ 0.05, ***p < 0.001, ****p < 0.0001.
