This study aimed to investigate the impact of abdominal aortic occlusion (AAO)-induced injury on the kidney, lower limb muscles, heart, and brain in mice, and the potential protective effects of hypoxic postconditioning (HyC). The experimental design employed an abdominal aortic occlusion (AAO) model, and involved three groups of mice: sham, AAO, and AAO+HyC. Ten minutes after the AAO model, mice were subjected to hypoxic treatment lowering oxygen concentration to 5% within 45 minutes, and then returned to a normal oxygen environment. Hematoxylin-eosin (HE) stain was used for Histopathological examinations, and Quantibody Mouse Array was used for detecting apoptosis and inflammation-related protein expression. Histopathological examinations showed that HyC mitigated pathological damage to proximal organs (kidneys and lower limb muscles), distal organs (heart and brain), and reduced inflammatory cell infiltration. Expression of apoptosis-and inflammation-related proteins in brain and heart tissues were also evaluated. HyC significantly increased cellular inhibitor of apoptosis 2 (cIAP2) in the brain and Bcl-2 and insulin-like growth factor 2 (IGF-2) in the heart. Additionally, HyC regulated the expression of several inflammation-related factors in both brain and heart tissues. Although further investigation is needed, particularly in human subjects, this study highlights the potential of HyC as a promising therapeutic strategy for reducing AAO-associated organ damage.
