SSE decreased the viability and proliferation of two renal cancer cell lines. 786-O and ACHN cells were treated with a range of SSE doses for up to 24 h. A Cell viability was determined using an MTT assay. Data from cells without SSE were as a baseline (100%). B The inhibitory effects of SSE on cell proliferation were determined using a colony formation assay. The black bars and white bars denote the quantitative analysis of 786-O cells and ACHN cells respectively. Data were expressed as means ± SD (n = 4), *P < 0.05 and ***P < 0.001
