Abstract Ischemia‐reperfusion injury (IRI) is the leading cause of hepatic graft dysfunction, resulting from hepatocyte damage. Nevertheless, given few specialized therapeutics available in IRI, additional mechanistic insights into damage are required. Here, protein solute carrier family 39 member 14 (SLC39A14) identified as a pro‐ferroptosis target hepatocytes human liver allografts through single‐cell RNA sequencing analysis. SLC39A14 knockdown significantly mitigated IRI by preventing ferroptosis vivo and vitro. Mechanistically, inhibition suppressed non‐transferrin‐bound iron (NTBI) uptake hepatocytes, thereby reducing overload cell ferroptosis. Moreover, bone marrow‐derived mesenchymal stem cells (hBMSCs) found to exhibit notable therapeutic effect on downregulating expression. Exosomes derived hBMSCs delivered abundant miR‐16‐5p which post‐transcriptionally expression reduced induced IRI. In conclusion, triggers mediating NTBI inducing hBMSC‐based therapy promising reverse this progression

The process of dead cell clearance by phagocytic cells, called efferocytosis, prevents inflammatory necrosis and promotes resolution repair. Defective efferocytosis contributes to the progression numerous diseases in which death prominent, including liver disease. Many gaps remain our understanding how macrophages carry out this goes awry various types diseases. Studies thus far have suggested that, upon injury, resident Kupffer cells (KCs) infiltrating monocyte-derived (MoMϕs) clear limit inflammation, and, through macrophage reprogramming, repair damage. However, unusual settings, can promote In review, we will focus on acute chronic diseases, metabolic dysfunction-associated steatohepatitis.

Baicalin is an active compound extracted from Scutellaria baicalensis with antioxidant and anti-inflammatory properties. Bone mesenchymal stem cells (BMSCs)-derived exosomes have shown promise for the treatment of hepatic ischemia-reperfusion (I/R) injury. This study aims to investigate role Baicalin-pretreated BMSCs-derived in I/R injury its mechanisms. BMSCs were pretreated or without Baicalin, their (Ba-Exo Exo) collected characterized. These administered mice via tail vein injection. Treatment Exo Ba-Exo significantly suppressed elevation ALT AST induced by Additionally, both treatments resulted a reduction liver weight-to-body weight ratio. RT-PCR results revealed significant downregulation pro-inflammatory cytokines treatment. Both improved Th17/Treg cell imbalance reduced cocultured normal cells, expression fibroblast growth factor 21 (FGF21) was elevated through After treatment, JAK2/STAT3 pathway inhibited, FOXO1 upregulated. Finally, recombinant FGF21 injected into mouse veins assess effects. Recombinant injection further inhibited pathway, increased expression, imbalance. In conclusion, this confirms protective effects against mitigates injury, achieved inducing inhibiting activating expression. Therefore, baicalin pretreatment emerges as promising strategy enhance therapeutic capability I/R.

Cell death is crucial for maintaining tissue balance and responding to diseases. However, under pathological conditions, the surge in dying cells results an overwhelming presence of cell debris release danger signals. In liver, this gives rise hepatic inflammation hepatocellular death, which are key factors various liver diseases caused by viruses, toxins, metabolic issues, or autoimmune factors. Both clinical vivo studies strongly affirm that hepatocyte serves as a catalyst progression disease. This advancement characterized successive stages inflammation, fibrosis, cirrhosis, culminating higher risk tumor development. review, we explore pivotal forms including apoptosis, pyroptosis, necroptosis, examining their roles both acute chronic cancer.

Cysteine dioxygenase type 1 (Cdo1) is a tumor suppressor gene. It regulates the metabolism of cysteine, thereby influencing cellular antioxidative capacity. This function puts Cdo1 in prominent position to promote ferroptosis and apoptosis. promotes mainly by decreasing amounts antioxidants, leading autoperoxidation cell membrane through Fenton reaction. apoptosis product cysteine metabolism, taurine, low level antioxidants. Many cancers exhibit altered Cdo1, underscoring its crucial role cancer survival. Genetic epigenetic alterations have been found, with methylation promoter as most common mutation. The fact that no was found be caused alone indicates mild. By compiling current knowledge about apoptosis, ferroptosis, this review suggests possibilities for how mild anticancer could harnessed new therapies. Here, developing drugs targeting considered meaningful neoadjuvant therapies, example, helping against development anti-cancer drug resistance cells.

Abstract Hepatic steatosis significantly elevates the vulnerability of graft to ischemia-reperfusion (I/R) injury during liver transplantation (LT). We investigated protective role insulin-induced gene 2 (Insig2) in steatotic liver’s I/R and underlying mechanisms. Employing mouse model with Insig2 knock-out or hepatocyte-specific overexpression high-fat diets induce steatosis, we subjected these mice hepatic injury. The primary hepatocytes isolated from were used vitro hypoxia/reoxygenation (H/R) experiment. Our integrated vivo approach uncovered that deficiency exacerbated damage following injury, whereas its offers protection. Mechanically, integrative analysis transcriptome, proteome, metabolome found disturbed lipid metabolism oxidative stress homeostasis, particularly inhibiting GPX4 expression ferroptosis. Furthermore, chemical inhibition ferroptosis reversed deleterious effect deficiency; influence was negated by target GPX4, leading an exacerbation damage. These insights underscored potential Insig2-GPX4 axis as a therapeutic target, presenting novel avenue for enhancing resilience grafts against
