Fig. 3From: Limb ischemic preconditioning ameliorates renal microcirculation through activation of PI3K/Akt/eNOS signaling pathway after acute kidney injuryInhibition of PI3K significantly decreased phosphorylation of Akt and eNOS. Representative photomicrographs of kidney sections of CI-AKI sections with p-eNOS staining (a). Score of p-eNOS staining was significantly decreased in WORT + LIPC + CM (b). Representative western blots and quantitative analysis of p-Akt and Akt (c), p-eNOS and eNOS (d). WORT significantly decreased the ratios of phosphorylated Akt and eNOS in LIPC + CM. Original magnification ×400. **P < 0.01; n = 6 each. The values shown are the mean ± SDBack to article page
