Figure 1. HO and biliverdin reductase (BvR) expression in microsomes and mitochondria. A) Typical Western blot analysis of HO-1, HO-2, and BvR expression in a control (C) animal and in animals treated with hemin (H) and hemin plus tin-protoporphyrin-IX (H+S) in mitochondria, microsomes, and cytosol. B) Typical Western blot analysis of COX subunits I and VIc and VDAC1 (a mitochondrial marker) expression in mitochondria from a control (C) animal and from animals treated with hemin and hemin plus SnPP (H and H+S, respectively).
