Time-course and dose-response of allyl-isothiocyanate (A) and sulforaphane (B) treatment effects on proliferation of PC-3 (black pillar) and DU 145 (grey pillar) cells as determined by trypan blue dye exclusion assay. Prostate cancer cells were plated, allowed to attach overnight, and treated with dimethyl sulfoxide (DMSO) (control) or desired concentration of allyl-isothiocyanate (AITC) or sulforaphane (SFN) and/or DOCE (docetaxel) for specified time intervals. Both floating and adherent cells were collected and used for counting of dead and live cells. Data are shown as the mean ± SD of three independent experiments. a, p < 0.05, ITC treatment alone significantly different compared with control treatment; b, p < 0.05, ITC treatment alone for 48 or 72 h significantly different compared with ITC treatment alone for 24 h; c, p < 0.05, ITC treatment alone for 72 h significantly different compared with ITC treatment alone for 48 h; d, p < 0.05, ITC treatment alone significantly different compared with 2 nM DOCE alone; e, p < 0.05, combination treatment (ITC + DOCE 1 nM) significantly different compared with 1 nM DOCE alone; f, p < 0.05, combination treatment (ITC + DOCE 2 nM) significantly different compared with 2 nM DOCE alone (one-way ANOVA).
