Hypertensive DS rats had a significant increase in mRNA expression of gp91phox (A), p22phox (B) compared with normotensive DS rats', BMT significantly reduced mRNA expression of gp91phox and p22 phox in hypertensive but not in normotensive DS rats. Hypertensive DS rats exhibited a reduction in eNOS (C) expression and an increase in the expression of proinflammatory cytokine TNFa (D) and MCP1 (E), BMT normalized eNOS expression but not inflammatory cytokines in hypertensive DS rats. N=4, *P<0.05 vs. NS group, #p<0.05 vs. HS group.
