Abstract:

Ubiquitin-proteasome system (UPS) is an adenosine triphosphate-dependent non-lysosomal protein degradation system in cells. It plays a role in many signal transduction pathways and can regulate a variety of cell biological processes, such as cell cycle regulation, signal transduction, apoptosis, DNA repair and gene expression and so on. Hepatic ischemia-reperfusion injury (HIRI) is a common pathophysiological phenomenon of liver transplantation and hepatectomy, which is one of the most important factors affecting the prognosis of patients. Recently, more and more studies have begun to focus on the role of UPS in the occurrence and development of HIRI, which provides new ideas and potential therapeutic targets for the clinical treatment and prevention of HIRI. This paper will review the research progress of UPS in HIRI.

Key words: Ubiquitin-proteasome system, Ischemia-reperfusion injury, Signal transduction, Liver transplantation
