Abstract
Acute liver failure (ALF) is a clinical syndrome characterized by the accelerated development of hepatocyte necrosis and significant mortality. Given that liver transplantation is now the only curative treatment available for ALF, there is an urgent need to explore innovative therapies. Mesenchymal stem cells (MSCs) have been applied in preclinical studies for ALF. It had been demonstrated that human embryonic stem cell-derived immunity-and-matrix regulatory cells (IMRCs) met the properties of MSCs and had been employed in a wide range of conditions. In this study, we conducted a preclinical evaluation of IMRCs in the treatment of ALF and investigated the mechanism involved. ALF was induced in C57BL/6 mice via intraperitoneal administration of 50% CCl4 (6 mL/kg) mixed with corn oil, followed by intravenous injection of IMRCs (3 × 106 cells/each). IMRCs improved histopathological changes in the liver and reduced alanine transaminase (ALT) or aspartate transaminase (AST) levels in serum. IMRCs also promoted cell renewal in the liver and protected it from CCl4 damage. Furthermore, our data indicated that IMRCs protected against CCl4-induced ALF by regulating the IGFBP2-mTOR-PTEN signaling pathway, which is associated with the repopulation of intrahepatic cells. Overall, IMRCs offered protection against CCl4-induced ALF and were capable of preventing apoptosis and necrosis in hepatocytes, which provided a new perspective for treating and improving the prognosis of ALF.

Liver Protection of a Low-Polarity Fraction from Ficus pandurata Hance, Prepared by Supercritical CO 2 Fluid Extraction, on CCl 4-Induced Acute Liver Injury in Mice via Inhibiting Apoptosis and Ferroptosis Mediated by Strengthened Antioxidation. Molecules 2023; 28:molecules28052078. [PMID: 36903326 PMCID: PMC10004706 DOI: 10.3390/molecules28052078] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 02/11/2023] [Accepted: 02/13/2023] [Indexed: 02/25/2023] Open
Abstract
Ficus pandurata Hance (FPH) is a Chinese herbal medicine widely used for health care. This study was designed to investigate the alleviation efficacy of the low-polarity ingredients of FPH (FPHLP), prepared by supercritical CO2 fluid extraction technology, against CCl4-induced acute liver injury (ALI) in mice and uncover its underlying mechanism. The results showed that FPHLP had a good antioxidative effect determined by the DPPH free radical scavenging activity test and T-AOC assay. The in vivo study showed that FPHLP dose-dependently protected against liver damage via detection of ALT, AST, and LDH levels and changes in liver histopathology. The antioxidative stress properties of FPHLP suppressed ALI by increasing levels of GSH, Nrf2, HO-1, and Trx-1 and reducing levels of ROS and MDA and the expression of Keap1. FPHLP significantly reduced the level of Fe2+ and expression of TfR1, xCT/SLC7A11, and Bcl2, while increasing the expression of GPX4, FTH1, cleaved PARP, Bax, and cleaved caspase 3. The results demonstrated that FPHLP protected mouse liver from injury induced by CCl4 via suppression of apoptosis and ferroptosis. This study suggests that FPHLP can be used for liver damage protection in humans, which strongly supports its traditional use as a herbal medicine.

Abstract
Acute liver failure (ALF) is an unfavorable condition characterized by the rapid loss of liver function and high mortality. Chrysophanol-8-O-glucoside (CPOG) is an anthraquinone derivative isolated from rhubarb. This study aims to evaluate the protective effect of CPOG on lipopolysaccharide (LPS)/D-GalN-induced ALF and its underlying mechanisms. LPS/D-GalN-induced mice ALF model and LPS treatment model in RAW 264.7 and LX2 cells were established. It was found that CPOG ameliorated LPS/D-GalN-induced liver injury and improved mortality as indicated by Hematoxylin-eosin (H&E) staining. Molecularly, qPCR and ELISA results showed that CPOG alleviated LPS/D-GalN-induced release of alanine aminotransferase and aspartate transaminase and the secretion of TNF-α and IL-1β in vivo. LPS/D-GalN-induced intracellular ROS production was also attenuated by CPOG in liver tissue. Further, CPOG attenuated ROS generation and inhibited the expression of p-IκB and p-p65 as well as the expression of TNF-α and IL-1β stimulated by LPS in RAW 264.7 cells. In addition, CPOG alleviated LPS-induced up-regulation of LC3B, p62, ATG5 and Beclin1 by attenuating ROS production and inhibiting MAPK signaling in LX2 cells. Taken together, our data indicated that the CPOG protected against LPS/D-GalN-induced ALF by inhibiting oxidative stress, inflammation response and autophagy. These findings suggest that CPOG could be potential drug for the treatment of ALF in clinic.

Abstract
Materials and Methods The potential bioactive compounds of PCRR and their targets were collected from TCMSP, TCMID, and BATMAN-TCM databases with absorption, distribution, metabolism, and excretion protocols (oral bioavailability ≥30% and drug-likeness ≥0.18). The ALF-related target genes were identified using the GeneCards and OMIM databases. A protein-protein interaction (PPI) network among these targets was constructed using the Cytoscape software to obtain the core targets. The genes associated with ALF were analyzed via Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses to identify the signaling pathways related to the therapeutic effect of PCRR in ALF. Results In total, 10 bioactive compounds of PCRR and 200 targets related to them were obtained, and 2913 ALF-related target genes were identified. PPI network analysis pinpointed 15 core targets, namely, TP53, AKT1, JUN, HSP90AA1, MAPK1, RELA, TNF, ESR1, IL6, MYC, MAPK14, FOS, RB1, CDKN1A, and EGFR. GO enrichment and KEGG pathway analyses revealed that the therapeutic mechanisms of PCRR in ALF are related to cell metabolism, oxidative stress, inflammation, and hepatocyte apoptosis. Conclusion This is the first study to explore the therapeutic mechanisms of PCRR in ALF via network pharmacology and molecular docking. This study provides a research platform with candidate ALF-related targets of PRCC for the development of therapeutics against ALF.

Abstract
BACKGROUND AND AIM The epithelial cells are the strongest determinants of the physical intestinal barrier. Tight junctions (TJs) hold the epithelial cells together and allow for selective paracellular permeability. Larazotide acetate (LA) is a synthetic octapeptide that reduces TJ permeability by blocking zonulin receptors. In this study, we aimed to investigate the effects of LA, a TJ regulator, on the liver and intestinal histology in the model of acute liver failure (ALF) in rats. MATERIALS AND METHODS The thioacetamide (TAA) group received intraperitoneal (ip) injections of 300 mg/kg TAA for 3 days. The TAA+LA(dw) (drinking water) group received prophylactic 0.01 mg/mL LA orally for 7 days before the first dose of TAA. The LA(dw) group received 0.01 mg/mL LA orally. The TAA + LA(g) (gavage) group received prophylactic 0.01 mg/mL LA via oral gavage for 7 days before the first dose of TAA. The LA(g) group received 0.01 mg/mL LA via oral gavage. While liver tissue was evaluated only with light microscopy, intestinal samples were examined with light and electron microscopy. RESULTS Serum ammonia, AST, and ALT levels in the TAA group were significantly higher than in control groups (all p < 0.01). Serum ALT levels in the TAA + LA(dw) group were significantly lower than in the TAA group (p < 0.05). However, serum ammonia and ALT levels did not differ between the TAA and other groups. Serious liver damage in the TAA group was accompanied by marked intestinal damage. There was no significant difference between the TAA and TAA + LA(dw) groups and TAA and TAA + LA(g) groups for liver damage scores. However, intestinal damage scores significantly decreased in the TAA + LA(dw) group compared to the TAA group. In the TAA + LA(dw) group, fusion occurred between the surface epithelial cells of neighboring villi and connecting regions formed as epithelial bridges between the villi. CONCLUSION Our findings suggest that LA reduced intestinal damage by acting on TJs in the TAA-induced ALF model in rats.

Abstract
The haemorrhagic disease virus (RHDV) is a non‐cultivable virus that promotes in rabbits an acute disease which accomplishes many characteristics of an animal model of fulminant hepatic failure (FHF). Beneficial effects of melatonin have been reported in RHDV‐infected rabbits. This study investigated whether protection against viral‐derived liver injury by melatonin is associated with modulation of mitophagy, innate immunity and clock signalling. Rabbits were experimentally infected with 2 × 104 haemagglutination units of a RHDV isolate and killed at 18, 24 and 30 hours after infection (hpi). Melatonin (20 mg/kg body weight ip) was administered at 0, 12 and 24 hpi. RHDV infection induced mitophagy, with the presence of a high number of mitophagosomes in hepatocytes and increased expression of mitophagy genes. Greater expression of main innate immune intermediaries and inflammasome components was also found in livers with RHDV‐induced FHF. Both mitophagy and innate immunity activation was significantly hindered by melatonin. FHF induction also elicited an early dysregulation in clock signalling, and melatonin was able to prevent such circadian disruption. Our study discloses novel molecular routes contributing to RHDV‐induced damage progression and supports the potential of melatonin as a promising therapeutic option in human FHF.

Abstract
Pyroptosis is known as a novel form of pro-inflammatory cell death program, which is exceptional from other types of cell death programs. Particularly, pyroptosis is characterized by Gasdermin family-mediated pore formation and subsequently cellular lysis, also release of several pro-inflammatory intracellular cytokines. In terms of mechanism, there are two signaling pathways involved in pyroptosis, including caspase-1, and caspase-4/5/11 mediated pathways. However, pyroptosis plays important roles in immune defense mechanisms. Recent studies have demonstrated that pyroptosis plays significant roles in the development of liver diseases. In our review, we have focused on the role of pyroptosis based on the molecular and pathophysiological mechanisms in the development of liver diseases. We have also highlighted targeting of pyroptosis for the therapeutic implications in liver diseases in the near future.

Therapeutic benefits of apocynin in mice with lipopolysaccharide/D-galactosamine-induced acute liver injury via suppression of the late stage pro-apoptotic AMPK/JNK pathway. Biomed Pharmacother 2020; 125:110020. [PMID: 32106375 DOI: 10.1016/j.biopha.2020.110020] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 02/12/2020] [Accepted: 02/13/2020] [Indexed: 12/14/2022] Open
Abstract
The excessive generation of reactive oxygen species (ROS) plays crucial roles in the development of acute liver injury. Nicotinamide adenine dinucleotide phosphate oxidase (NOX) is responsible for the robust production of ROS under inflammatory circumstance, but the pathological roles of NOX and the pharmacological significance of NOX inhibitor in acute liver injury remains unclear. In the present study, the potential roles of NOX in acute liver injury were investigated in a mouse model with lipopolysaccharide (LPS)/D-galactosamine (D-Gal)-induced acute liver injury. The results indicated that LPS/D-Gal exposure time-dependently increased the level of ROS in liver tissue. Pretreatment with the NOX inhibitor apocynin suppressed LPS/D-Gal induced upregulation of ROS, 8-hydroxy-2-deoxyguanosine (8-OH-dG), protein carbonyl content and thiobarbituric acid reactive substances (TBARS). Pretreatment with apocynin also suppressed LPS/D-Gal-induced elevation of aminotransferase, alleviated histological abnormalities, inhibited the production of pro-inflammatory cytokine tumor necrosis factor α (TNF-α), blocked the activation of caspase cascade, reduced the count of TUNEL-positive cells and prevented LPS/D-Gal-induced mortality. Interestingly, post insult treatment with apocynin also suppressed LPS/D-Gal-induced oxidative stress, hepatocyte apoptosis, liver damage but improved the survival rate. Mechanistically, posttreatment with apocynin prohibited LPS/D-Gal-induced activation of the late stage pro-apoptotic AMP-activated protein kinase (AMPK)/c-Jun N-terminal kinase (JNK) pathway. Post-insult treatment with the antioxidant N-acetylcysteine also resulted in suppressed activation of AMPK/JNK, mitigated apoptosis and alleviated liver injury. These data suggest that NOX-derived ROS might be a crucial late stage detrimental factor in LPS/D-Gal-induced acute liver injury via promoting the activation of the pro-apoptotic AMPK/JNK pathway, and the NOX inhibitor might have important value in the pharmacological intervention of inflammation-base liver damage.

Abstract
Acute liver failure is a severe clinical syndrome accompanied with excessive inflammatory response. Our previous study demonstrated that SKLB023, a novel thiazolidinedione derivative, showed potent anti-inflammatory activity in rheumatoid arthritis. The purpose of the present study is to evaluate the protective effect of SKLB023 on lipopolysaccharide (LPS)/D-GalN-induced liver failure and to explore the underlying molecular mechanisms. Our results showed that SKLB023 significantly improved mortality and liver injury as indicated by reduced serum levels of aminotransferases and alleviated pathological damage. Additionally, SKLB023 decreased the percentage of activated T cells and macrophages as well as the serum levels of cytokines in vivo. Furthermore, SKLB023 decreased levels of TNF-α and IL-6 secreted from liver macrophages (Kupffer cells) stimulated by LPS in vitro. Our results indicated that the protective effects of SKLB023 were associated with its significant impact on the inflammatory cytokines, which were produced by both T cells and macrophages. A novel thiazolidinedione derivative SKLB023 offers a potent therapeutic strategy for the treatment of acute liver failure.![]()
