(A) Comparison between rat and human Biliverdin Reductase (rBVRA and hBVRA) activity in the presence of 0, 15, 30 or 60 μM Montelukast or (B) 0, 15, 30 or 60 μM Disulfiram. The conversion of biliverdin to bilirubin was determined by measuring absorbance over a period of 60 minutes at wavelengths 453 nm (bilirubin) and 670 nm (biliverdin). Biliverdin reductase activity was determined by calculating the slope over the linear part of the reaction and is expressed as residual activity relative to the vehicle control 1% DMSO. Data represent the mean ± SD of the data obtained from three independent experiments (n = 3). Two-way analysis of variance (ANOVA) was used for statistical analysis, **p < 0.01, ***p < 0.001.
