Abstract
Aims: Mitochondrial dysfunction is the primary mechanism of liver ischemia/reperfusion (I/R) injury. The lysine desuccinylase sirtuin 5 (SIRT5) is a global regulator of the mitochondrial succinylome and has pivotal roles in mitochondrial metabolism and function; however, its hepatoprotective capacity in liver I/R remains unclear. In this study, we established liver I/R model in SIRT5-silenced and SIRT5-overexpressed mice to examine the role and precise mechanisms of SIRT5 in liver I/R injury. Results: Succinylation was strongly enriched in liver mitochondria during I/R, and inhibiting mitochondrial succinylation significantly attenuated liver I/R injury. Importantly, the levels of the desuccinylase SIRT5 were notably decreased in liver transplant patients, as well as in mice subjected to I/R and in AML12 cells exposed to hypoxia/reoxygenation. Furthermore, SIRT5 significantly ameliorated liver I/R-induced oxidative injury, apoptosis, and inflammation by regulating mitochondrial oxidative stress and function. Intriguingly, the hepatoprotective effect of SIRT5 was mediated by PRDX3. Mechanistically, SIRT5 specifically desuccinylated PRDX3 at the K84 site, which enabled PRDX3 to alleviate mitochondrial oxidative stress during liver I/R. Innovation: This study denoted the new effect and mechanism of SIRT5 in regulating mitochondrial oxidative stress through lysine desuccinylation, thus preventing liver I/R injury. Conclusions: Our findings demonstrate for the first time that SIRT5 is a key mediator of liver I/R that regulates mitochondrial oxidative stress through the desuccinylation of PRDX3, which provides a novel strategy to prevent liver I/R injury.

Abstract
Background Sevoflurane can protect organs from ischemia-reperfusion (IR) injury, but the mechanism is still unclear. MicroRNA-122 (miR-122) is a liver-specific microRNA (miRNA) and regulates liver function. Therefore, this study aims to elucidate the relationship between the protective effect of sevoflurane and miR-122 in liver IR injury. Methods Wistar rats were divided into the following groups: sham, IR, IR + sevoflurane, IR + miR-122 antagomir, and IR + miR-122 antagomir + sevoflurane. Hematoxylin and eosin (H&E) staining and Suzuki score were used to evaluate the pathological damage of the liver. The levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH), tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6, and IL-10 in the serum and the levels of malondialdehyde (MDA), superoxide dismutase (SOD), and nitric oxide (NO) in the liver homogenate supernatant were detected by using the corresponding kit. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling (TUNEL) and flow cytometry was applied to evaluate the apoptosis of liver tissues. The expression of nuclear factor E2-related factor 2 (Nrf2), miR-122, p53, and HO-1 in liver tissue was evaluated by using immunohistochemistry, qRT-PCR, and western blot as needed. Results Compared to the IR group, the sevoflurane post-treatment or miR-122 antagomir groups showed improved liver injury, decreased Suzuki score, inhibited the levels of AST, ALT, LDH, MDA, NO, TNF-α, IL-1β, and IL-6, increased levels of SOD, IL-10, and inhibited hepatocyte apoptosis. Regarding the molecular mechanism, sevoflurane post-treatment fostered the expression of HO-1, promoted the transport of Nrf2 from cytoplasm to the nucleus, and decreased the expression of miR-122 and p53. The combined use of miR-122 antagomir and sevoflurane enhanced the protective effect of miR-122 antagomir in liver injury in IR rats. Conclusions Sevoflurane protected the liver from IR damage by regulating the miR-122/Nrf2/HO-1 pathway.

Dihydromyricetin protects against liver ischemia/reperfusion induced apoptosis via activation of FOXO3a-mediated autophagy. Oncotarget 2018; 7:76508-76522.

Abstract
Liver ischemia and reperfusion (I/R) injury is characterized by defective liver autophagy accompanied by alterations to the endogenous defense system. Dihydromyricetin (DHM) is a natural flavonoid that demonstrates a wide range of physiological functions, and has been implicated as a regulator of autophagy. This study investigates the protective effects of DHM pretreatment on liver injury caused by ischemia/reperfusion (I/R) and elucidates the potential mechanism of DHM-mediated protection. Mice were subjected to 60 minutes of ischemia followed by 5 hours of reperfusion. DHM (100 mg/kg bw/day) or the vehicle was administered daily by gavage 7 days before ischemia and immediately before reperfusion. In this study, DHM markedly decreased serum aminotransferase activity and inhibited liver I/R -stimulated apoptosis. Moreover, DHM exerted hepatoprotective effects by upregulating mRNA levels of various essential autophagy-related genes including ATG5, ATG12, BECN1, and LC3. Autophagy inhibitor chloroquine or Atg5 knockdown blocked DHM -mediated elevation in liver function. Specifically, DHM significantly increased FOXO3a expression, and enhanced FOXO3a nuclear translocation and Ser588 phosphorylation modification. Importantly, the inhibition of FOXO3a with FOXO3a-siRNA in mice decreased DHM-induced autophagy-related genes and diminished the protective effects of DHM against liver I/R injury. In summary, these findings identify DHM as a novel hepatoprotective small molecule by elevating FOXO3a expression and nuclear translocation, stimulating autophagy-related genes and suppressing liver I/R-induced apoptosis, suggesting FOXO3a may have therapeutic value in liver cell protection in liver I/R injury.

Abstract
In recent years, hyperbaric oxygen (HBO) has been used in the treatment of a lot of diseases such as decompression sickness, arterial gas embolism, carbon dioxide poisoning, soft tissue infection, refractory osteomyelitis, and problematic wound, but little is known about its application in liver transplantation. Although several studies have been conducted to investigate the protective effects of HBO on liver transplantation and liver preservation, there are still some controversies on this issue, especially its immunomodulatory effect. In this short review, we briefly summarize the findings supporting the application of HBO during liver transplantation (including donors and recipients).

Abstract
Hydrogen has been demonstrated to function as a novel antioxidant and exert therapeutic antioxidant activity in a number of diseases. The present study was designed to investigate the effect of hydrogen inhalation on liver ischemia/reperfusion (I/R) injury in rats. The portal triad to the left lobe and the left middle lobe of the liver were completely occluded for 90 min. This was followed by reperfusion for 180 min. The rats subsequently underwent syngeneic orthotopic liver transplantation. Inhalation of various concentrations (1, 2 and 3%) of hydrogen gas and its administration for different durations (1, 3 and 6 h) immediately prior to the I/R injury allowed the optimal dose and duration of administration to be determined. Liver injury was evaluated through biochemical and histopathological examinations. The expression levels of proinflammatory cytokines, including tumor necrosis factor (TNF)-α and interleukin (IL)-6, were measured by enzyme-linked immunosorbent assay and quantitative polymerase chain reaction (qPCR). Liver nuclear factor κB (NF-κB) was detected by qPCR and western blot analysis. Inhalation of hydrogen gas at 2% concentration for 1 h significantly reduced the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, the expression of cytokines, including IL-6, TNF-α, early growth response protein 1 (Egr-1) and IL-1β, and morphological damage. In addition, the mRNA and protein expression levels of NF-κB, heme oxygenase-1 (HO-1), B-cell lymphoma 2 (Bcl-2) and zinc finger protein A20 (A20) in rats where only the donors received hydrogen were significantly increased compared with those in rats where both the donor and recipient, or only the recipient received hydrogen. The results indicate that hydrogen inhalation at 2% concentration for 1 h prior to liver transplantation protected the rats from ischemia/reperfusion injury by activation of the NF-κB signaling pathway.

Abstract
BACKGROUND AND AIM The purpose of the present study was to determine the effects of interleukin-37 (IL-37) on liver cells and on liver inflammation induced by hepatic ischemia/reperfusion (I/R). METHODS Mice were subjected to I/R. Some mice received recombinant IL-37 (IL-37) at the time of reperfusion. Serum levels of alanine aminotransferase, and liver myeloperoxidase content were assessed. Serum and liver tumor necrosis factor-α (TNF-α), macrophage inflammatory protein-2 (MIP-2) and keratinocyte chemokine (KC) were also assessed. Hepatic reactive oxygen species (ROS) levels were assessed. For in vitro experiments, isolated hepatocytes and Kupffer cells were treated with IL-37 and inflammatory stimulants. Cytokine and chemokine production by these cells were assessed. Primary hepatocytes underwent induced cell injury and were treated with IL-37 concurrently. Hepatocyte cytotoxicity and Bcl-2 expression were determined. Isolated neutrophils were treated with TNF-α and IL-37 and neutrophil activation and respiratory burst were assessed. RESULTS IL-37 reduced hepatocyte injury and neutrophil accumulation in the liver after I/R. These effects were accompanied by reduced serum levels of TNF-α and MIP-2 and hepatic ROS levels. IL-37 significantly reduced MIP-2 and KC productions from lipopolysaccharide-stimulated hepatocytes and Kupffer cells. IL-37 significantly reduced cell death and increased Bcl-2 expression in hepatocytes. IL-37 significantly suppressed TNF-α-induced neutrophil activation. CONCLUSIONS IL-37 is protective against hepatic I/R injury. These effects are related to the ability of IL-37 to reduce proinflammatory cytokine and chemokine production by hepatocytes and Kupffer cells as well as having a direct protective effect on hepatocytes. In addition, IL-37 contributes to reduce liver injury through suppression of neutrophil activity.
