Caption : figure s1. combination treatment of luteolin and quercetin significantly reduction of ube2s in a431-iii cells. (a) cell variability analysis of a431-iii cells combined treatment with luteolin and quercetin for 24 h using an mtt assay. (b) quantification of the transcript levels of ube2s by a qpcr with 0.1% dmso (control), individual or combined with 20 μm of luteolin and quercetin treatment for 24 h. (c) western blot analysis of ube2s expression levels after either 0.1% dmso (control), 10 and 20 μm of luteolin, 20 μm and 40 μm of quercetin and combined with 20 μm of luteolin and 20 μm of quercetin treatment for 24 h. *** indicates a significant difference compared to the control (p<0.001).
