Popis: The aim of the present study was to investigate the preconditioning effect and underlying mechanisms of cobalt-protoporphyrin (CoPP) in a mouse model of liver ischemia‑reperfusion (I/R) injury. Mice were divided into five groups: Sham‑operated (control), I/R, I/R + CoPP, I/R + CoPP and zinc‑protoporphyrin (ZnPP) and I/R + ZnPP. Serum levels of aspartate transaminase (AST) and alanine aminotransferase (ALT) were detected using commercial kits. The expression of the pro‑apoptotic protein caspase‑3 was detected by immunohistochemistry and the expression levels of the anti‑apoptotic protein B‑cell lymphoma 2 (Bcl‑2) and heme oxygenase 1 (HO‑1) were analyzed by western blotting. Sections of liver tissue were stained with hematoxylin and eosin to observe pathologic alterations. Furthermore, hepatocyte apoptosis was detected using a terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. AST and ALT levels of the CoPP preconditioned group were significantly reduced compared with the IR injury group (P
