Analysis of CE expression in human lung and kidney microsomes.
A - Graph indicating the levels of CE activity (black bars) and SN-38 production (white bars) from individual kidney microsomal samples.
B – Graph indicating the levels of CE activity (black bars) and SN-38 production (white bars) by both pooled and individual lung microsomal samples. NS – non smokers; S – smokers.
C – Western analysis of hiCE and hCE1 expression in individual human kidney microsomal extracts. Purified hiCE and hCE1 protein (50ng) were included as positive controls.
D – Western analysis of hiCE and hCE1 expression in pooled human lung microsomal extracts isolated from 4 individuals. Purified hiCE and hCE1 protein (50ng) were included as positive controls. As before, NS – non smokers; S – smokers.
E – Coomassie blue stained gel demonstrating equal loading of the samples analyzed in panel C.
F – Prolonged exposure of a western analysis using larger amounts (200μg) of lung microsomal extracts following immunoblotting with hiCE antibody. L - human liver microsomes.
G – Coomassie blue stained gel demonstrating equal loading of the samples analyzed in the western analyses. As above, NS – non smokers; S – smokers.
