Hepatic ischemia-reperfusion injury (IRI) is an important factor in the recovery of liver function and prognosis after liver surgery. 15-hydroxyprostaglandin dehydrogenase (15-PGDH) small molecule inhibitor SW033291 is thought to play an important role in promoting tissue regeneration. The aim of this study was to investigate the effect of 15-PGDH on ischemia-reperfusion injury in mouse liver. In this study, mice in the administered group showed lower necrosis and inflammation than control mice, partly due to reduced macrophage and neutrophil infiltration in liver tissue, as well as reduced serum or tissue levels of pro-inflammatory cytokines and oxidative stress. In addition, mice in the administered group showed increased post-injury reparation due to IRI-induced injury compared to control mice. CONCLUSION: The small molecule inhibitor SW033291 played a better role in preventing hepatic ischemia-reperfusion injury in mice and may be a potential option to prevent the development and progression of hepatic I/R.

Background: The protective function of the tetrandrine (TET)-mediated transient receptor potential vanilloid 2 (TRPV2) channel in myocardial ischemia/reperfusion injury (MI/RI) has been established in numerous investigations. The objective of the current study was to explain how TRPV2 further modulates downstream factors to influence the progression of MI/RI.
Methods: To this end, an MI/RI model in rats and a hypoxia-reoxygenation (H/R) cell model in H9c2 cells were constructed.

Acute kidney injury (AKI) is a group of common clinical syndromes characterized by a rapid decline in renal function over a short period of time. At present, the treatment methods are limited, and research is needed to identify drugs that could alleviate renal ischemia-reperfusion (I/R) injury. Tetramethylpyrazine (TMP) is a bioactive alkaloid extracted from the Chinese herbal medicine Chuanxiong.

Protein kinases have crucial roles in intracellular signal transduction pathways that affect a wide range of biochemical processes, including apoptosis, metabolism, proliferation, and protein synthesis. Vascular endothelial cells are important regulators of vasomotor tone, tissue/organ perfusion, and inflammation. Since its discovery in the late 1970s, a growing body of literature implicates protein kinase C (PKC) in pathways involving angiogenesis, endothelial permeability, microvascular tone, and endothelial activation.

Notoginsenoside R1 (NGR1), a natural triterpenoid saponin, is extracted from , and has cardiovascular and cerebrovascular protective effects due to anti-inflammatory, anti-oxidant, and anti-apoptotic properties. Previous research has suggested a protective role for NGR1 in myocardial ischemia/reperfusion (MI/R) injury. However, the potential mechanisms involved have not been fully elucidated.
