Effect of NAR on the cell viability and apoptosis. (A) HCT116 and SW480 cells were treated with NAR at the indicated concentrations for 24 h. (B) HT-29 and LoVo cells were treated with 200 μM of NAR for 24 h. Cell viability was measured using MTT assay system and expressed as % cell viability. ^*p<0.05 compared to cells without NAR. (C) HCT116 cells were treated with NAR at the indicated concentrations for 24 h. Cell lysates were subjected to SDS-PAGE and Western blot was performed using antibodies against Cleaved PARP and actin.
