Curcumin, the major component of the spice turmeric, used in 50- micro M concentration, induced cell death in multidrug-resistant CEM(P-gp4) and LoVo(P-gp4) cells as well as in their sensitive counterparts as assessed by TUNEL method and morphological observation. In all cells induced to undergo cell death with curcumin, there was no caspase-3 activation because only the unprocessed form of caspase-3 was observed using immunoblotting.
