Deficiency of heme oxygenase-1 impairs renal hemodynamics and exaggerates systemic inflammatory responses to renal ischemia  M.J. Tracz, J.P. Juncos, A.J. Croatt, A.W. Ackerman, J.P. Grande, K.L. Knutson, G.C. Kane, A. Terzic, M.D. Griffin, K.A.

2 Figure 1 Renal hemodynamics in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). The data demonstrate the following hemodynamic parameters: glomerular filtration rate (GFR), renal blood flow (RBF), renal vascular resistance (RVR), and filtration fraction (FF). n=4 in each of the HO-1+/+ and HO-1−/− groups subjected to sham ischemia; n=6 and n=8 (GFR), and n=5 and n=7 (RBF, RVR, and FF) in HO-1+/+ and HO-1−/− groups subjected to IR respectively. *P<0.05 versus HO-1+/+ mice subjected to the same condition.

3 Figure 2 Cardiac function in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). The data demonstrate the following: heart rate (beats per minute), circumferential shortening velocity (circumferences/s), fractional shortening (%), and cardiac output (ml/min/30 g). n=5 in each of the HO-1+/+ Sham and HO-1+/+ IR groups, and n=6 in each of HO-1−/− Sham and HO-1−/− IR groups.

4 Figure 3 HO-1 expression in the kidney 4 h after sham or IR injury. Upper panel: Western analysis for HO-1 protein expression in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). Each lane represents protein extracted from a single kidney of an individual mouse. Equivalency of protein loading was verified by Ponceau staining (not shown). Lower panel: HO-1 mRNA by quantitative real-time reverse transcriptase-PCR in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). n=4 in each of the HO-1+/+ Sham and HO-1−/− Sham groups, and n=6 and n=8 in HO-1+/+ IR and HO-1−/− IR groups respectively.

5 Figure 4 IL-6 mRNA determination by quantitative real-time reverse transcriptase-PCR in the kidney in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). n=4 and n=5 in the HO-1+/+ Sham and HO-1−/− Sham groups respectively, and n=8 and n=7 in the HO-1+/+ IR and HO-1−/− IR groups respectively. *P<0.05 versus HO-1+/+ mice subjected to the same condition.

6 Figure 5 Western analysis for pSTAT3 and STAT3 expression in the kidney in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). Each lane represents protein extracted from a single kidney of an individual mouse, and equivalency of protein loading was verified by immunoblotting for β-actin.

7 Figure 6 Serum levels of IL-6 in HO-1+/+ and HO-1−/− mice subjected to ischemia– reperfusion injury (IR) or sham ischemia (Sham). n=4 and n=5 in the HO-1+/+ Sham and HO-1−/− Sham groups respectively, and n=8 and n=7 in the HO-1+/+ IR and HO-1−/− IR groups respectively. *P<0.05 versus HO-1+/+ mice subjected to the same condition.

8 Figure 7 Serum levels of IL-12 (p40) in HO-1+/+ and HO-1−/− mice subjected to ischemia– reperfusion injury (IR) or sham ischemia (Sham). n=4 and n=5 in the HO-1+/+ Sham and HO-1−/− Sham groups respectively, and n=8 and n=7 in the HO-1+/+ IR and HO-1−/− IR groups respectively. *P<0.05 versus HO-1+/+ mice subjected to the same condition.

9 Figure 8 Serum levels of IL-5 and macrophage inflammatory protein (MIP)-1α in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). n=4 and n=5 in the HO-1+/+ Sham and HO-1−/− Sham groups respectively, and n=8 and n=7 in the HO-1+/+ IR and HO-1−/− IR groups respectively. *P<0.05 versus HO-1+/+ mice subjected to the same condition.

10 Figure 9 IL-6 mRNA determination by quantitative real-time reverse transcriptase-PCR in the heart and lung in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). For studies in either organ, n=4 and n=5 in the HO-1+/+ Sham and HO-1−/− Sham groups respectively, and n=8 and n=7 in the HO-1+/+ IR and HO-1−/− IR groups respectively. *P<0.05 versus HO-1+/+ mice subjected to the same condition.

11 Figure 10 Western analysis for pSTAT3 and STAT3 expression in the lung in HO-1+/+ and HO-1−/− mice subjected to ischemia–reperfusion injury (IR) or sham ischemia (Sham). Each lane represents protein extracted from a single lung of an individual mouse, and equivalency of protein loading was verified by immunoblotting for β-actin.
