Curcumin reverses oxaliplatin resistance in SW480 cells. (A) MTT assay was performed to calculate the growth inhibition rate of SW480 and SW480/OXA cells treated with 0.5, 1, 2, 4, 8, 16 or 32 μM OXA for 48 hrs. (B) The growth inhibition rate of SW480/OXA cells treated with the combination of OXA and curcumin. (C) SW480/OXA cell death was detected with trypan blue staining. (D) Trypan blue positive cell rate in each group was calculated. Each experiment was repeated three times. **P<0.01 compared to control group; ##P<0.01, compared to OXA alone group.
