Abstract
Retinal ischemia exists in various ischemic retinopathies including glaucoma, contributing to the death of retinal neurons. Calcium binding protein S100A4 is important in tumors, and our previous study found that S100A4 protects retinal ganglion cells (RGCs) against retinal ischemia-reperfusion (I/R) injury. This study was aimed to further discuss the neuroprotection and mechanisms of S100A4 in retinal I/R of mice. The rAAV-EF1α-s100a4-EGFP-WPRE or rAAV-EF1α-EGFP-WPRE-Pa was injected intravitreally 4 weeks before I/R. S100A4, molecules in TLR4 signaling pathway and endoplasmic reticulum (ER) stress branches, inflammatory molecules, and surviving RGCs and cholinergic amacrine (ChAT) cells were determined by quantitative PCR, western blot, or immunofluorescent staining. The apoptosis and necrosis of retinal neurons induced by I/R were inhibited by overexpressed S100A4. RGCs, ChAT cells, and the retinal function were preserved by S100A4 overexpressing 7 days after I/R. Mechanistically, the beneficial effects of S100A4 may be mediated by inhibiting the activation of TLR4 signaling pathway and alleviating ER stress, leading to the attenuation of inflammatory response of the retina after I/R. Our findings indicated that S100A4 has neuroprotective effect against retinal I/R injury, and promoting S100A4 expression may be an effective strategy to inhibit retinal neurons from degeneration in ischemic retinopathy.

Toxicol Res (Camb) 2022; 11:718-729. [PMID: 36337252 PMCID: PMC9618097 DOI: 10.1093/toxres/tfac045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Revised: 06/15/2022] [Accepted: 06/27/2022] [Indexed: 12/27/2022] Open
Abstract
BACKGROUND Verapamil (VER) and cilostazol (Cilo) are mostly used as cardiovascular drugs; they have beneficial effects on different organs toxicities. AIM we investigated whether the Nuclear factor erythroid 2-related factor 2 (Nrf2), Glycogen synthase kinase-3β (GSK-3β), and Nuclear factor-kappa B (NF-κB) pathway involved in the protective role of these drugs against Thioacetamide (TAA) induced hepatotoxicity. METHOD male rats were randomized divided into five groups, each group (n = 10): control, TAA, VER+TAA, Cilo+TAA, and VER+Cilo+TAA groups. Hepatotoxicity induced in rats by TAA injection once on the 7th day of the experiment. RESULTS TAA-induced hepatotoxicity indicated by a significant elevated in serum markers (Alanine aminotransferases (ALT), Aspartate aminotransferases (AST), and bilirubin), oxidative stress markers (Malondialdehyde (MDA), and Nitric oxide (NO)), and protein levels markers (NF-κB, and S100 calcium-binding protein A4 (S100A4)). Also, TAA decreased Nrf2, and increased GSK-3β genes expression. Histopathological alterations in the liver also appeared as a response to TAA injection. On the other hand VER and/or Cilo significantly prevented TAA-induced hepatotoxicity in rats through significantly decreased in ALT, AST, bilirubin, MDA, NO, NF-κB, and S100A4 protein levels. Also, they increased Nrf2 and decreased GSK-3β genes expression which caused improvement in the histopathological changes of the liver. CONCLUSION the addition of verapamil to cilostazol potentiated the hepatoprotective activity, and inhibited the progression of hepatotoxicity caused by TAA through the Nrf2/GSK-3β/NF-κBpathway and their activity on oxidative stress, inflammation, and NF-κB protein expression.

Abstract
Background Alcoholic liver disease (ALD) is one of the most prevalent chronic liver disease worldwide. Alcohol-induced alterations in hepatic lipids play an important role in ALD develpoment and progression. The present study aimed to thoroughly describe the changes of lipid profiling in liver of mice with early-stage alcoholic liver disease. Methods C57BL/6J male mice aged 7-week were randomized into alcohol-fed (AF) group and pair-fed control group (PF) (n = 10 per group). The early stage of ALD was induced with Lieber-DeCarli liquid diet. The lipids profiling was analyzed by absolute quantitative lipidomics with UHPLC-QTRAP-MS/MS. Results Alcohol intake significantly increased the levels of alanine aminotransferase (ALT) in plasma, and tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and triacylglycerols (TAG) levels in liver. Lipidomis analyses showed that 41 TAGs were up-regulated and 8 TAGs were down-regulated in response to alcohol intake. The 8 decreased TAGs were with more double bond, longer carbon chain length and mostly contained docosahexaenoic acid (C22:6n-3) and eicosapentaenoic acid (C20:5n-3), compared with the up-regulated TAGs. Furthermore, the down-regulated TAG(56:9)_FA20:5 was inversely associated with ALT and IL-6 levels. In addition, several altered lysophosphatidylcholines (LPC), lysophosphatidylethanolamines (LPE) and hexosylceramides (HCER) were all significantly decreased in response to alcohol consumption, especially HCer(18:1/22:0), with the top reduction among all the down-regulated lipids. Conclusions These findings suggest that not only the up-regulated lipids, alcohol-induced reduction in some specific lipids might also contribute to the ALD development, especially TAG(56:9)_FA20:5 and HCer(18:1/22:0). Their physiological functions and effects on ALD development warrants further investigation.

Abstract
Hepatic encephalopathy (HE) following acute and chronic liver failure is defined as a complex of neuropsychiatric abnormalities, such as discrete personal changes, sleep disorder, forgetfulness, confusion, and decreasing the level of consciousness to coma. The use and design of suitable animal models that represent clinical features and pathological changes of HE are valuable to map the molecular mechanisms that result in HE. Among different types of animal models, thioacetamide (TAA) has been used extensively for the induction of acute liver injury and HE. This agent is not directly hepatotoxic but its metabolites induce liver injury through the induction of oxidative stress and produce systemic inflammation similar to that seen in acute HE patients. In this short review article, we shortly review the most important pathological findings in animal models of acute HE following the administration of TAA.

Abstract
The administration with high dose (close to LD50) of thioacetamide (TAA), a hepatotoxicant used widely to induce experimental liver lesions, develops hepatocellular necrosis and subsequent inflammation (mainly M1-/M2-macrophages without neutrophil infiltration) in rats. We analyzed rat livers treated with a low dose TAA (50 mg/kg/body weight) at 6, 12, 18, 24 and 48 hr. The lesions in the affected centrilobular areas consisted of slight hepatocyte degeneration at 12 hr, and inflammatory cell infiltration at 18 and 24 hr; the lesions recovered until 48 hr. Translocation of intranuclei to cytoplasm of HMGB1, a representative molecule of damage-associated molecular patterns, was seen in some hepatocytes mainly at 6, 12, and 18 hr. As an interesting finding, at 12 hr, myeloperoxidase-positive neutrophil infiltration was observed in the affected centrilobular area. Additionally, CD68 M1-/CD163 M2-macrophages increased consistently at 12 to 48 hr. CXCL1, a chemokine for induction of neutrophils, began to increase at 6 hr and gradually increased at 12, 18 and 24 hr, apparently corresponding to the appearance of neutrophils. Collectively, the present findings at the low dose TAA indicated that along with M1-/M2-macrophages, neutrophils were characteristically seen, which might be elicited by cytoplasmic translocation of HMGB1 from nuclei. These finding would be useful for evaluation of hepatotoxicity at the early stages.

Abstract
ABSTRACT Host cells recognize molecules that signal danger using pattern recognition receptors (PRRs). Toll-like receptors (TLRs) are the most studied class of PRRs and detect pathogen-associated molecular patterns and danger-associated molecular patterns. Cellular TLR activation and signal transduction can therefore contain, combat, and clear danger by enabling appropriate gene transcription. Here, we review the expression, regulation, and function of different TLRs, with an emphasis on TLR-4, and how TLR adaptor protein binding directs intracellular signaling resulting in activation or termination of an innate immune response. Finally, we highlight the recent progress of research on the involvement of S100 proteins as ligands for TLR-4 in inflammatory disease.

Abstract
Resident and infiltrative macrophages play important roles in the development of
pathological lesions. M1/M2 macrophage polarization with respective CD68 and CD163
expression remains unclear in chemically induced liver injury. This study was aimed at
investigating the influence of macrophages on normal and chemically induced liver injury.
For this, dexamethasone (DX), an immunosuppressive drug, was administered in normal rats
and thioacetamide (TAA)-treated rats. Liver samples were collected and analyzed with
immunohistochemical methods. Repeated injections of DX (0.5 or 1.0 mg/kg BW) for 3, 7 and
11 days reduced the number of CD163 positive hepatic resident macrophages (Kupffer cells)
in normal livers, while increasing AST and ALT levels. In TAA (300 mg/kg BW)-treated rats
injected with DX (0.5 mg/kg BW) pretreatment, the number of M1 and M2 macrophages showed a
significant decrease compared with that of TAA-treated rats without DX treatment.
Additionally, reparative fibrosis resulting from hepatocyte injury induced by TAA
injection was suppressed by DX pretreatment. Our data suggested that macrophages could
influence not only normal hepatic homeostasis (reflected by AST and ALT levels) but also
chemically induced hepatic lesion development (reduced reparative fibrosis).

Abstract
Macrophages and myofibroblasts are important in fibrogenesis. The cellular characteristics in pancreatic fibrosis remain to be investigated. Pancreatic fibrosis was induced in F344 rats by a single intravenous injection of dibutyltin dichloride. Histopathologically, the induced pancreatic fibrosis was divided into 3 grades (1+, 2+, and 3+), based on collagen deposition. Immunohistochemically, CD68-expressing M1 macrophages increased with grade and CD163-expressing M2 macrophages also increased later than M1 macrophage appearance. Double immunofluorescence showed that there were macrophages coexpressing CD68 and CD163, suggesting a possible shift from M1 to M2 types; similarly, increased major histocompatibility complex class II- and CD204-expressing macrophages were polarized toward M1 and M2 types, respectively. These findings indicated the participation of M1- and M2-polarized macrophages. Mesenchymal cells staining positive for vimentin, desmin, and α-smooth muscle actin (α-SMA) increased with grade. There were mesenchymal cells coexpressing vimentin/α-SMA, desmin/α-SMA, and glial fibrillary acidic protein (GFAP)/α-SMA; Thy-1-expressing immature mesenchymal cells also increased in fibrotic lesions. Because α-SMA expression is a reliable marker for myofibroblasts, α-SMA-expressing pancreatic myofibroblasts might be originated from GFAP-expressing pancreatic stellate cells or Thy-1-expressing immature mesenchymal cells; the myofibroblasts could simultaneously express cytoskeletal proteins such as vimentin and desmin. The present findings would provide useful information for analyses based on features of macrophages and myofibroblasts in chemically induced pancreatic fibrosis.

Abstract
The natural compound Zerumbone (hereinafter referred to as ZER), a monocyclic sesquiterpenoid, has been reported to possess many pharmacological properties, including antioxidant and anti-inflammatory properties. This study aimed to investigate the underlying mechanism of ZER against acute liver injury (ALI) in CCl4-induced mice models. ICR mice were pretreated intraperitoneally with ZER for five days, then received a CCl4 injection two hours after the last ZER administration and were sacrificed 24 h later. Examination of serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities and the histopathological analysis confirmed the hepatoprotective effect of ZER. Biochemical assays revealed that ZER pretreatment recovered the activities of antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), restored the glutathione (GSH) reservoir, and reduced the production of malondialdehyde (MDA), all in a dose-dependent manner. Furthermore, administration of ZER in vivo reduced the release amounts of pro-inflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) and inhibited the increased protein levels of Toll-like receptor 4 (TLR4), nuclear factor-kappaB (NF-κB) p-p65, and cyclooxygenase (COX-2). Further studies in lipopolysaccharide (LPS)-induced Raw264.7 inflammatory cellular models verified that ZER could inhibit inflammation via inactivating the TLR4/NF-κB/COX-2 pathway. Thus, our study indicated that ZER exhibited a hepatoprotective effect against ALI through its antioxidant and anti-inflammatory activities and the possible mechanism might be mediated by the TLR4/NF-κB/COX-2 pathway. Collectively, our studies indicate ZER could be a potential candidate for chemical liver injury treatment.

Abstract
Liver macrophages make up the largest proportion of tissue macrophages in the host and consist of two dissimilar groups: Kupffer cells (KCs) and monocyte-derived macrophages (MoMø). As the liver is injured, KCs sense the injury and initiate inflammatory cascades mediated by the release of inflammatory cytokines and chemokines. Subsequently, inflammatory monocytes accumulate in the liver via chemokine-chemokine receptor interactions, resulting in massive inflammatory MoMø infiltration. When live r injury ceases, restorative macrophages, derived from recruited inflammatory monocytes (lymphocyte antigen 6 complex, locus Chi monocytes), promote the resolution of hepatic damage and fibrosis. Consequently, a large number of studies have assessed the mechanisms by which liver macrophages exert their opposing functions at different time-points during liver injury. The present review primarily focuses on the diverse functions of macrophages in experimental liver injury, fibrosis and repair in mice and illustrates how macrophages may be targeted to treat liver disease.

Abstract
AIMS Stevioside is a diterpenoid obtained from the leaves of Stevia rebaudiana (Bertoni) that exhibits antioxidant, antifibrotic, antiglycemic and anticancer properties. Therefore, we aimed to study whether stevioside has beneficial effects in liver injury induced by long-term thioacetamide (TAA) administration and investigated the possible underlying molecular mechanism using in vivo, in vitro and in silico approaches. MAIN METHODS Liver injury was induced in male Wistar rats by TAA administration (200 mg/kg), intraperitoneally, three times per week. Rats received saline or stevioside (20 mg/kg) twice daily intraperitoneally. In addition, cocultures were incubated with either lipopolysaccharide or ethanol. Liver injury, antioxidant and immunological responses were evaluated. KEY FINDINGS Chronic TAA administration induced significant liver damage. In addition, TAA upregulated the protein expression of nuclear factor (NF)-κB, thus increasing the expression of proinflammatory cytokines and decreasing the antioxidant capacity of the liver through downregulation of nuclear erythroid factor 2 (Nrf2). Notably, stevioside administration prevented all of these changes. In vitro, stevioside prevented the upregulation of several genes implicated in liver inflammation when cocultured cells were incubated with lipopolysaccharide or ethanol. In silico assays using tumor necrosis factor receptor (TNFR)-1 and Toll-like receptor (TLR)-4-MD2 demonstrated that stevioside docks with TNFR1 and TLR4-MD2, thus promoting an antagonistic action against this proinflammatory mediator. SIGNIFICANCE Collectively, these data suggest that stevioside prevented liver damage through antioxidant activity by upregulating Nrf2 and immunomodulatory activity by blocking NF-κB signaling.

[PMID: 29151689 PMCID: PMC5685841 DOI: 10.3748/wjg.v23.i41.7347] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2017] [Revised: 08/22/2017] [Accepted: 09/13/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To studied iron metabolism in liver, spleen, and serum after acute liver-damage, in relation to surrogate markers for liver-damage and repair.
METHODS Rats received intraperitoneal injection of the hepatotoxin thioacetamide (TAA), and were sacrificed regularly between 1 and 96 h thereafter. Serum levels of transaminases and iron were measured using conventional laboratory assays. Liver tissue was used for conventional histology, immunohistology, and iron staining. The expression of acute-phase cytokines, ferritin light chain (FTL), and ferritin heavy chain (FTH) was investigated in the liver by qRT-PCR. Western blotting was used to investigate FTL and FTH in liver tissue and serum. Liver and spleen tissue was also used to determine iron concentrations.
RESULTS After a short initial decrease, iron serum concentrations increased in parallel with serum transaminase (aspartate aminotransferase and alanine aminotransferase) levels, which reached a maximum at 48 h, and decreased thereafter. Similarly, after 48 h a significant increase in FTL, and after 72h in FTH was detected in serum. While earliest morphological signs of inflammation in liver were visible after 6 h, increased expression of the two acute-phase cytokines IFN-γ (1h) and IL-1β (3h) was detectable earlier, with maximum values after 12-24 h. Iron concentrations in liver tissue increased steadily between 1 h and 48 h, and remained high at 96 h. In contrast, spleen iron concentrations remained unchanged until 48 h, and increased mildly thereafter (96 h). Although tissue iron staining was negative, hepatic FTL and FTH protein levels were strongly elevated. Our results reveal effects on hepatic iron concentrations after direct liver injury by TAA. The increase of liver iron concentrations may be due to the uptake of a significant proportion of the metal by healthy hepatocytes, and only to a minor extent by macrophages, as spleen iron concentrations do not increase in parallel. The temporary increase of iron, FTH and transaminases in serum is obviously due to their release by damaged hepatocytes.
CONCLUSION Increased liver iron levels may be the consequence of hepatocyte damage. Iron released into serum by damaged hepatocytes is obviously transported back and stored via ferritins.

Abstract
Chronic liver disease patients often have complications, such as hepatocellular carcinoma (HCC) and acute bacterial infection. Model for end‐stage liver disease and Child‐Pugh scores are useful prognostic factors for chronic liver diseases but not for all chronic conditions, such as HCC. Our investigative aim targeted the prognostic abilities of neutrophil gelatinase‐associated lipocalin (NGAL) in rat and human chronic liver diseases. Blood NGAL levels were measured by enzyme‐linked immunosorbent assay in rats with cirrhosis and 96 patients with chronic liver disease and HCC. We examined the correlation between blood NGAL levels and liver functions as well as survival. In our rat model, liver NGAL expression was assessed by immunostaining, real‐time quantitative polymerase chain reaction, and immunoblot. In rats with cirrhosis, blood NGAL levels were continuously and significantly elevated in the deceased group and were significantly correlated with liver functions. Liver NGAL, toll‐like receptor 4, and interleukin‐6 levels were increased in the deceased group compared to the survival group. Blood NGAL levels were significantly correlated with liver NGAL levels, indicating blood NGAL was derived from the liver. In patients with chronic liver disease, blood NGAL levels were associated with liver function and renal function. Blood NGAL levels were significantly increased in patients with chronic liver disease with HCC compared to without HCC. For the survival group, 38 out of 96 patients were dead in the average follow‐up period of 9.9 months. The patients with blood NGAL ≤119 ng/mL had significantly longer rates of survival compared to patients with blood NGAL >119 ng/mL. Conclusion: Blood NGAL predicts the survival rate in rat and human chronic liver diseases. Our findings suggest blood NGAL may be prognostic of survival in chronic liver diseases complicated by HCC.

Attenuation of thioacetamide-induced hepatocellular injury by short-term repeated injections associated with down-regulation of metabolic enzymes and relationship with MHC class II-presenting cells. ACTA ACUST UNITED AC 2017; 69:589-597. [PMID: 28559049 DOI: 10.1016/j.etp.2017.05.005] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2017] [Revised: 05/13/2017] [Accepted: 05/15/2017] [Indexed: 12/15/2022]
Abstract
The liver is the primary organ participating in the metabolism of xenobiotics and is therefore an important target in the safety assessment of drugs, chemicals and environmental toxins. Drug-induced liver injury (DILI) has recently become widely recognized in human medicine as an adverse event. The progression of DILI often involves "damage-associated molecular patterns" (DAMPs) of gene and protein expression such as high-mobility group boxes (HMGBs), S100 proteins and heat shock proteins (Hsp). DAMPs are released from injured or necrotic cells and are bound to Toll-like receptors (TLRs) and modulate inflammatory reactions. Previously, in thioacetamide (TAA; 300mg/kg body weight, single injection)-induced rat liver, we demonstrated that the expressions of DAMPs, TLR4 and major histocompatibility complex (MHC) class II were simultaneously increased, accompanied with progression of hepatocellular injury and inflammation. Here we investigated the association of DILI and DAMPs, TLRs and MHC class II by using rat livers repeated injections with TAA (100mg/kg body weight, once, three times). Two days after TAA single injection, centrilobular hepatocellular necrosis with infiltration of mononuclear cells was observed, being paralleled with increase in serum levels of aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP). However, two days after duplicate and triplicate injections, only mild degenerative change of hepatocytes and slight infiltration of mononuclear cells were seen in the affected centrilobular area. Serum levels of AST, ALT and ALP were also decreased to the same levels of control. mRNA expressions of DAMPs (HMGBs, S100A4 and Hsp 70-2), TLR4 and MHC class II tended to be increased only on single injection, although the number of MHC class II-positive cells in the centrilobular area was still increased on each examination point. The analysis of enzymes (CYP2E1 and Flavin monooxygenase (FMO) 3), which metabolize TAA in hepatocytes, showed a significant decrease in FMO3 on the duplicate and triplicate injections. Autophagy and regulatory T cells were not significantly changed for the attenuation of hepatocyte injury. Collectively, these results suggest that hepatocytes may adapt accumulation of the toxicant by changing their enzyme functions; furthermore, MHC class II cells, which still showed increased number in the duplicate and triplicate injections, may be related with protection from the toxicant.

Histopathological Analysis of Rat Hepatotoxicity Based on Macrophage Functions: in Particular, an Analysis for Thioacetamide-induced Hepatic Lesions. Food Saf (Tokyo) 2016; 4:61-73. [PMID: 32231908 DOI: 10.14252/foodsafetyfscj.2016012] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2016] [Accepted: 08/30/2016] [Indexed: 12/21/2022] Open
Abstract
Hepatic macrophages play an important role in homeostasis. The functional abnormalities of hepatic macrophages primarily or secondarily influence chemically induced hepatotoxicity. However, the evaluation system based on their functions has not yet been established. Recently, a new concept (M1-/M2-macrophage polarization) was proposed; M1-macropahges are induced by INF-γ, and show high phagocytosis/tissue damage, whereas M2-macropahges are induced by IL-4 and play roles in reparative fibrosis by releasing IL-10 and TGF-β1. In hepatogenesis, CD68-expressing M1-macrophages predominantly exist in embryos; in neonates, in contrast, CD163-/CD204-expressing M2-macrophages appear along the sinusoids and mature as Kupffer cells. Activated Kupffer cells by liposome decrease AST and ALT values, whereas AST and ALT values are increased under Kupffer cells depleted with clodronate treatment. Since Kupffer cells may be involved in clearance of liver enzymes, macrophage condition should be taken into consideration when hepatotoxicity is analyzed. In TAA-induced acute hepatic lesions, INF-γ, TNF-α and IL-6 for M1-factors and IL-4 for M2-factors are already increased before histopathological change; the appearance of CD68-expressing M1-macrophages and CD163-expressing M2-macrophages follows in injured centrilobular lesions, and TGF-β1 and IL-10 are increased for reparative fibrosis. CD68-expressing M1-macrophages co-express MHC class II and Iba-1, whereas CD163-expressing M2-macrophages also express CD204 and Galectin-3. Under macrophage depletion by clodoronate, TAA-treated rat livers show prolonged coagulation necrosis of hepatocytes, and then develop dystrophic calcification without reparative fibrosis. The depletion of hepatic macrophages influences hepatic lesion development. Collectively, a histopathological analysis method for hepatotoxicity according to M1-/M2-macrophage polarization would lead to the refinement of hazard characterization of chemicals in food and feed.
