Additionally, pretreatment of mice with the PPARγ agonist rosiglitazone can alleviate HIRI induced by ischemia by inhibiting the activation of the PI3K-AKT1-FOXO3 signaling pathway to induce autophagy.<h4>Conclusion</h4>Peroxisome proliferator activated receptor gamma inhibited the PI3K-AKT1-FOXO3 signaling pathway, which in turn activated autophagy to alleviate HIRI. This evidence concerns the gene PPARG and ischemia.
