Inhibition of Notch1 signaling causes an increased Caspase-8 cleavage and DISC formation upon TRAIL treatment. (a) U251MG cells transduced with control-AdV or Notch1sh-AdV (72 h) were treated with TRAIL (40 ng/ml) for the indicated times. Total cell lysates were subjected to immunoblot analysis for Notch1 and Caspase-8. Asterisk indicate cleaved Caspase-8 fragments (*=p41/p43; **=p24/p26). (b) Control-AdV and Notch1sh-AdV transduced U251MG cells (72 h) were treated with Flag-TRAIL (500 ng/ml) for the indicated time points. Subsequently, Flag was immunoprecipitated and immunoblots were probed with DR5 and Caspase-8 antibodies. Whole cell lysates were used for input controls
