Additional file 3: of Isoliquiritigenin suppresses human melanoma growth by targeting miR-301b/LRIG1 signaling

Figure S1. ISL inhibits cell proliferation and induces cell apoptosis in melanoma cells in vitro. (A) MEWO cells were treated with ISL (0, 10, 20, 40, 80 μM) for 24 h, and cell viability was analyzed by CCK-8 assay. (B) MEWO cells were treated with 20 μM ISL, cell proliferation at indicated time (24, 48, 72 h) was measured by CCK-8 assay. (C, D) Flow cytometry analysis of apoptosis of MEWO cells after being treated with ISL (0, 10, 20 μM) for 24 h. (E, F) Representative images and quantification of colony formation of MEWO cells after being treated with ISL (0, 5, 10 Μm). (G, H)Western blot analysis of the protein level of apoptosis associated proteins(bcl-2, bax, parp, cleaved-caspase-3) in ISL treated A375 and A2058 cells. *P
