Intraperitoneal infusion of LPS upregulates NADPH oxidase subunits and antioxidants in RVLM. Representative gels (inset) and densitometric analysis of results from Western blot showing changes in expression of gp91phox (A), p47phox (B), Cu/ZnSOD (C), MnSOD (D), ecSOD (E), catalase (F), or glutathione peroxide (GPx) (G) in RVLM, determined on day 7 after intraperitoneal infusion of saline or LPS (1.2 mg/kg/day), alone or with additional intracisternal infusion of NS398 (1.5 nmol/μL/h) or minocycline (9 nmol/μL/h). Values are mean ± SEM (n=8 to 10 animals in each experimental group). *P <0.05 vs. saline-treatment group; #
P <0.05 vs. LPS-treatment group in the post hoc Scheffé multiple-range test.
