Reciprocal Effects of Oxidative Stress on Heme Oxygenase Expression and Activity Contributes to Reno-Vascular Abnormalities in EC-SOD Knockout Mice

Figure 3

(a) Superoxide levels in femoral arteries of WT mice, EC-SOD(−/−) mice, and mice injected with CoPP. Superoxide levels were determined as described in methods. Results are mean ± SE, ; * versus WT, versus EC-SOD(−/−); + versus WT + CoPP. (b) Dose-response curves for acetylcholine-induced vascular relaxation after preconstriction with phenylephrine. Results are mean ± SE, ; * versus WT, versus EC-SOD(−/−), + versus WT + CoPP, and (c) systolic blood pressure measurements at the completion of the study ( ). Mice were injected with CoPP once a week as described in Methods. Blots are representative of four separate experiments. Results are expressed as mean ± SE, * versus WT, versus EC-SOD(−/−), + versus WT + CoPP mice, and Western blot and densitometry analysis of (d) eNOS and p-eNOS.
