Mechanistic studies revealed that celecoxib‐induced cardiac protection against CH and cardiac dysfunction was due to inhibition of apoptosis via the murine double mimute 2/P53 pathway, inhibition of inflammation via the AKT/mTOR/NF‐κB pathway and inhibition of oxidative stress via increases in nuclear factor E2‐related factor‐2‐mediated gene expression of multiple antioxidants. This evidence concerns the gene MTOR and cyclic hematopoiesis.
