Inflammation is crucial to tumorigenesis and the development of metastasis. Hepatic ischemia/reperfusion injury (IRI) is an unresolved problem in liver resection and transplantation which often establishes and remodels the inflammatory microenvironment in liver. More and more experimental and clinical evidence unmasks the role of hepatic IRI and associated inflammation in promoting the recurrence of hepatocellular carcinoma (HCC). Meanwhile, approaches aimed at alleviating hepatic IRI, such as machine perfusion, regulating the gut-liver axis, and targeting key inflammatory components, have been proved to prevent HCC recurrence. This review article highlights the underlying mechanisms and promising therapeutic strategies to reduce tumor recurrence through alleviating inflammation induced by hepatic IRI.

Hepatic ischemia-reperfusion injury (IRI) poses a significant clinical challenge in liver surgery and transplantation, primarily mediated through oxidative stress, mitochondrial dysfunction, and inflammatory activation. Herein, we developed SOD2-Res@CVs, an engineered vesicular platform combining SOD2-overexpressing mesenchymal stem cell-derived vesicles with liver-targeted and ROS-responsive resveratrol (Res)-loaded liposomes for multi-mechanistic intervention. In vivo imaging demonstrated that SOD2-Res@CVs selectively accumulated in IRI-damaged hepatic tissues.

Purpose: Ex vivo machine perfusion (EVMP) is increasingly recognized as a promising technique for enhancing the preservation and viability of donor organs, particularly in donation after circulatory death (DCD) liver transplantation (LT). This study validates a transplant surgeon-innovated EVMP protocol by assessing its efficacy in preserving liver function and reducing ischemia-reperfusion injury (IRI) in a porcine DCD-simulated liver transplant (DCD sLT) model.
Materials And Methods: Twenty Yorkshire pigs were used to compare static cold storage (SCS) and EVMP.

Reactive oxygen species (ROS) play a dual role as both essential signaling molecules and harmful mediators of damage. Imbalances in the redox state of the liver can overwhelm antioxidant defenses and promote mitochondrial dysfunction, oxidative damage, and inflammation. Complex feedback loops between ROS and immune signaling pathways are a hallmark of pathological liver conditions, such as hepatic ischemia-reperfusion injury (IRI).

Background And Aims: Hepatic ischaemia-reperfusion injury (IRI), a common complication after hepatectomy and liver transplantation (LT), is a local sterile inflammatory response driven by innate immunity. Myocyte enhancer factor-2D (MEF2D) plays an important role in immune inflammatory response by transcriptionally activating or inhibiting gene expression, which is tightly associated with the pathogenic progression of hepatic disorders. However, the role of MEF2D in hepatic IRI is still unclear.

Hepatic ischemia-reperfusion injury (IRI) is a major complication following liver transplantation and significantly contributes to graft failure. Despite extensive research, an optimal preventive method remains elusive. Recently, fibroblast growth factors (FGFs) have emerged as key mediators of tissue repair and homeostasis.
