Figure 4

Effect of CDDO-Me and enzalutamide (ENZ) combination on cell viability of PC cells. Cytotoxic effect of CDDO-Me (250 and 500 nM) alone and in combination with ENZ (20 μM) at 72 h post treatment in (A) 22Rv1, (B) C4-2B, and (C) LNCaP cells is shown. PC cells were treated with CDDO-Me alone and in combination with ENZ and cell viability was measured at 72 h using MTT. The data (% of control) are expressed as the mean ± SEM of three independent experiments (n = 3) and significant differences between groups are shown as p-values (*p < 0.05).
