Hypoxia preconditioning protects Ca2+-ATPase activation of intestinal mucosal cells against R/I injury in a rat liver transplantation model

Figure 1 Expression of HIF-1α in liver and intestinal tissues in a rat autologous orthotopic liver transplantation model. A: Western blot assay showed that the level of HIF-1α protein expression induced by hypoxia preconditioning was increased in rat liver tissue at 12 h postoperatively; B: The chart shows that the level of HIF-1α in the HP group was higher at different postoperative time points. At 12 h postoperatively, HIF-1α expression in liver tissue in the HP group was significantly higher than in the AT group and NC group; C: Western blot assay showed that HIF-1α expression was increased in rat intestinal tissue after hypoxia preconditioning at 12 h postoperatively; D: The chart shows that HIF-1α expression induced by hypoxia preconditioning in intestinal tissue was elevated at different postoperative time points. HIF-1α expression was significantly higher in the HP group compared with the AT group and NC group at 12 h postoperatively.
