Antioxidant properties of glutamine and its role in VEGF-Akt pathways in portal hypertension gastropathy

Figure 3 Expression of endothelial nitric oxide synthase and vascular endothelial growth factor determined by Western blotting in gastric tissue from rats in the sham-operated group, the partial portal vein ligation group and rats subjected to partial portal vein ligation and glutamine treatment. A: An increase in eNOS expression was observed in the PPVL group vs the SO group. The PPVL + G group showed reduced expression of this enzyme vs the PPVL group; B: An increase in VEGF expression was detected in the PPVL group vs the SO group. The PPVL + G group did not show a reduction in the expression of VEGF vs the PPVL group. SO: Sham-operated; PPVL: Partial portal vein ligation; G: Glutamine; VEGF: Vascular endothelial growth factor; eNOS: Endothelial nitric oxide synthase; WB: Western blotting. ^aP < 0.05 vs the SO group.
