Fig. 1. Combined cytotoxic effect of sTRAIL and proteasome inhibitors in human glioma cell lines.
U87 and HOG glioma cell lines were treated with hrTRAIL for 24 hours followed by measurement of cytotoxicity (upper panel). The combined cytotoxic effects of epoxomicin and bortezomib and sTRAIL are presented in middle and lower panel, respectively. Data are shown as mean±SD, * p<0.05.
