Modulations on the expression and phosphorylation of proteins involved in apoptosis, proliferation and drug resistance. LAPC-4-AI (A) and PC-3 (B) cells were treated with vehicle control, 40μM EGCG+5μM Q, 5nM Doc, or EGCG+Q+Doc at same concentrations for 48h. Protein expression and phosphorylation were analyzed with Western blot. Data are presented as mean values. * Compared to NT, ** compared to NT, GT+Q or Doc group, P<0.05. NT: non-treatment, DMSO control; Q: quercetin; Doc: docetaxel.
