The effect of LR and BR on superoxide production. Superoxide production was determined by flow cytometry in live cells after overnight LR and BR treatment (5 and 25 μmol/L) from the detected slope. Rotenone (ROT) was used as a positive control of superoxide generation. Basal superoxide production (dashed lines) was detected in the cells without ROT treatment. *, p < 0.05; ns, not significant compared to ROT, n = 4 for each experiment CTRL, control cells without LR and BR treatment; BR, bilirubin; LR, lumirubin. Data expressed as the change in proportion of superoxide-producing cells upon various treatments.
