[PMID: 38599475 DOI: 10.1016/j.jep.2024.118107] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 03/14/2024] [Accepted: 03/23/2024] [Indexed: 04/12/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Paeonia lactiflora Pall. (PLP), a traditional Chinese medicine, is recognized for its antioxidative and anti-apoptotic properties. Despite its potential medicinal value, the mechanisms underlying its efficacy have been less explored, particularly in alleviating acute liver injury (ALI) caused by excessive intake of acetaminophen (APAP). AIM OF THE STUDY This study aims to elucidate the role and mechanisms of PLP in mitigating oxidative stress and apoptosis induced by APAP. MATERIALS AND METHODS C57BL/6 male mice were pre-treated with PLP for seven consecutive days, followed by the induction of ALI using APAP. Liver pathology was assessed using HE staining. Serum indicators, immunofluorescence (IF), immunohistochemical (IHC), and transmission electron microscopy were employed to evaluate levels of oxidative stress, ferroptosis and apoptosis. Differential expression proteins (DEPs) in the APAP-treated and PLP pre-treated groups were analyzed using quantitative proteomics. Subsequently, the potential mechanisms of PLP pre-treatment in treating ALI were validated using western blotting, molecular docking, molecular dynamics simulations, and surface plasmon resonance (SPR) analysis. RESULTS The UHPLC assay confirmed the presence of three compounds, i.e., albiflorin, paeoniflorin, and oxypaeoniflorin. Pre-treatment with PLP was observed to ameliorate liver tissue pathological damage through HE staining. Further confirmation of efficacy of PLP in alleviating APAP-induced liver injury and oxidative stress was established through liver function serum biochemical indicators, IF of reactive oxygen species (ROS) and IHC of glutathione peroxidase 4 (GPX4) detection. However, PLP did not demonstrate a significant effect in alleviating APAP-induced ferroptosis. Additionally, transmission electron microscopy and TUNEL staining indicated that PLP can mitigate hepatocyte apoptosis. PKC-ERK pathway was identified by proteomics, and subsequent molecular docking, molecular dynamics simulations, and SPR verified binding of the major components of PLP to ERK protein. Western blotting demonstrated that PLP suppressed protein kinase C (PKC) phosphorylation, blocking extracellular signal-regulated kinase (ERK) phosphorylation and inhibiting oxidative stress and cell apoptosis. CONCLUSION This study demonstrates that PLP possesses hepatoprotective abilities against APAP-induced ALI, primarily by inhibiting the PKC-ERK cascade to suppress oxidative stress and cell apoptosis.

Abstract
Acetaminophen (APAP)-induced liver injury is one of the most frequent causes of acute liver failure worldwide. Significant increases in the levels of miRNA-21 in both liver tissues and plasma have been observed in APAP-overdosed animals and humans. However, the mechanistic effect of miRNA-21 on acute liver injury remains unknown. In this study, we generated a new hepatocyte-specific miRNA-21 knockout (miR-21-HKO) mouse line. miR-21-HKO and the background-matched sibling wild-type (WT) mice were treated with a toxic dose of APAP. Compared with WT mice, miR-21 HKO mice showed an increased survival, a reduction of necrotic hepatocytes, and an increased expression of light chain 3 beta, which suggested an autophagy activation. The expression of PPARγ was highly induced in the livers of miR-21-HKO mice after a 2-h APAP treatment, which preceded the activation of LC3B at the 12 h APAP treatment. miR-21 negatively regulated PPARγ protein expression by targeting its 3'-UTR. When PPARγ function was blocked by a potent antagonist GW9662 in miR-21-HKO mice, the autophage activation was significantly diminished, suggesting an indispensable role of PPARγ signaling pathway in miR-21-mediated hepatotoxicity. Taken together, hepatocyte-specific depletion of miRNA-21 alleviated APAP-induced hepatotoxicity by activating PPARγ and autophagy, demonstrating a crucial new regulatory role of miR-21 in APAP-mediated liver injury.

Protective Effect of Water-Soluble Acacetin Prodrug on APAP-Induced Acute Liver Injury Is Associated with Upregulation of PPARγ and Alleviation of ER Stress. Int J Mol Sci 2023; 24:11320. [PMID: 37511082 PMCID: PMC10380069 DOI: 10.3390/ijms241411320] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/28/2023] [Accepted: 06/29/2023] [Indexed: 07/30/2023] Open
Abstract
A water-soluble acacetin prodrug has been synthesized and reported by our group previously. Acetaminophen (APAP) overdose is a leading cause of acute liver injury. We found that subcutaneous injection of acacetin prodrug (5, 10, 20 mg/kg) decreased serum ALT, AST, and ALP, corrected the abnormal MDA and GSH in liver, and improved intrahepatic hemorrhage and destruction of liver structures in APAP (300 mg/kg)-treated mice. Molecular mechanism analysis revealed that the expressions of endoplasmic reticulum (ER) stress markers ATF6, CHOP, and p-PERK, apoptosis-related protein BAX, and cleaved caspase 3 were decreased by acacetin in a dose-dependent manner in vivo and in vitro. Moreover, via the acacetin-upregulated peroxisome-proliferator-activated receptor gamma (PPARγ) of HepG2 cells and liver, the suppressive effect of acacetin on ER stress and apoptosis was abolished by PPARγ inhibitor (GW9662) or PPARγ-siRNA. Molecular docking revealed that acacetin can bind to three active pockets of PPARγ, mainly by hydrogen bond. Our results provide novel evidence that acacetin prodrug exhibits significant protective effect against APAP-induced liver injury by targeting PPARγ, thereby suppressing ER stress and hepatocyte apoptosis. Acacetin prodrug is likely a promising new drug candidate for treating patients with acute liver injury induced by APAP.

Low 15d-PGJ2 status is associated with oxidative stress in chronic obstructive pulmonary disease patients. Inflamm Res 2023; 72:171-180. [PMID: 36371490 DOI: 10.1007/s00011-022-01637-4] [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: 07/02/2022] [Revised: 08/23/2022] [Accepted: 09/01/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND Peroxisome proliferator-activated receptor γ (PPARγ) is a ligand-dependent nuclear receptor and highly expressed in human and rodent lungs. 15-Deoxy-delta-12,14-prostaglandin J2 (15d-PGJ2), known for cyclopentenone prostaglandin, is the endogenous ligand of PPARγ. However, the associations among PPARγ, 15d-PGJ2 and chronic obstructive pulmonary disease (COPD) were unclear. METHODS All 130 fasting blood samples and 40 lung specimens were obtained from COPD patients and control subjects. Serum 15d-PGJ2 was detected by ELISA. The expressions of oxidative stress indicators were measured using western blotting and PPARγ nuclei were evaluated with immunohistochemistry in lungs. The associations among serum 15d-PGJ2, pulmonary PPARγ and oxidative stress indicators, and COPD were estimated. RESULTS Serum 15d-PGJ2 was reduced in COPD patients compared with healthy volunteers. Linear and logistic regression analysis indicated that serum 15d-PGJ2 was positively associated with pulmonary function in COPD patients. In addition, PPARγ-positive nuclei were reduced and oxidative stress indicators, included HO-1 and NOX-4, were increased in lungs of COPD patients. Further correlative analysis suggested that pulmonary function parameters was positively correlated with serum 15d-PGJ2 and pulmonary PPARγ-positive nuclei, inversely related to oxidative stress indicators in lungs of COPD patients. Pretreatment with 15d-PGJ2 obviously attenuated TNFα-induced oxidative stress in BEAS-2B cells. CONCLUSIONS Serum 15d-PGJ2 and pulmonary PPARγ are reduced, and oxidative stress is elevated in COPD patients. Serum 15d-PGJ2 is inversely associated with oxidative stress in COPD patients.

Abstract
Background and Objectives An overdose of acetaminophen (APAP) usually leads to acute liver injury, and oxidative stress is one of the fundamental mechanisms used to characterize it. Procyanidins (PCs) can reduce the oxidative stress in the liver of mice. This study aimed to investigate the potential protective role of PCs against APAP-induced acute liver injury. Materials and Methods Experiments were performed on male Kunming mice in six groups: phosphate-buffered saline, PCs, APAP, and PCs pretreated with 10, 50, and 100 mg/kg. The mice were peritoneally injected with PCs 30 min before the administration of APAP. First, survival rates of mice were scored every 12 hr for three days in succession. Furthermore, serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (T-Bil), total cholesterol (TC), triglyceride (TG), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-1 (IL-6) were determined. Additionally, histological analysis and hepatic oxidative stress including the levels of superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione (GSH) were assessed. Finally, the protein expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and SOD-1 was detected by Western blotting. Results The data indicated that PCs improved survival rates of APAP-induced liver injury in mice models. Moreover, PCs could reduce the elevated serum levels of ALT, AST, T-Bil, TC, TG, TNF-α, IL-1β, and IL-6 due to APAP exposure with a dose-dependent manner. Besides, PCs pretreatment attenuated hepatic histopathological damage and oxidative stress which manifested the increases of SOD and GSH, whereas the decrease of MDA. Furthermore, PCs enhanced the protein expression of Nrf2 and SOD-1 in the PCs pretreatment groups compared with the APAP group. Conclusion PCs ameliorated APAP-induced acute liver injury, and Nrf2 signaling pathway modulating antioxidative stress might be involved in it.

BIOMED RESEARCH INTERNATIONAL 2022; 2022:6098592.

Abstract
Background Excessive acetaminophen (APAP) use can lead to acute liver injury (ALI) by inducing endoplasmic reticulum stress (ERS). We previously found that pretreatment with the peroxisome proliferator-activated receptor-γ (PPAR-γ) ligand rosiglitazone (RSG) alleviated ALI in APAP-treated mice. Objective To examine if RSG-mediated hepatoprotection is associated with ERS suppression. Methods Forty-eight male CD-1 mice were randomly divided into control, RSG, APAP 4 h, APAP 24 h, RSG + APAP 4 h, and RSG + APAP 24 h groups. The RSG and RSG + APAP groups received RSG (20 mg/kg) by gavage 48, 24, and 1 h before intraperitoneal injection of 300 mg/kg APAP, while the APAP group received APAP alone and the control group received only normal saline. Animals were sacrificed immediately (RSG and control groups), 4 h (APAP 4 h and RSG + APAP 4 h), or 24 h (APAP 24 h and RSG + APAP 24 h) post-APAP injection. Liver tissues were collected for hematoxylin-eosin staining, TUNEL staining, and Western blotting for ERS-associated proteins. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels were also measured. A second cohort received APAP or RSG + APAP as described and were monitored for survival over one week. Results At 4 and 24 h following APAP injection alone, serum ALT and AST levels were significantly elevated, and central lobular necrosis of the liver was observed. Necrosis area reached 21.7% at 4 h and 32.1% at 24 h post-APAP, while apoptotic fractions reached 25.6% and 32.4%. Further, 50% of mice in the survival analysis cohort died within one week post-APAP. At 4 h post-APAP, the ERS marker glucose-regulated protein-78 (GRP78) and ERS-associated proteins pJNK, GRP78, p-eIF2α, pPERK, and pIRE were all significantly upregulated. Pretreatment with RSG significantly reduced serum ALT and AST, liver necrosis area, apoptosis rate, and expression of ERS-associated proteins compared to APAP alone, while increasing survival to 80%. Conclusions Rosiglitazone pretreatment can alleviate APAP-induced ALI by suppressing three branches of ERS signaling.

Abstract
The goal of this study was to analyze whether mitochondria-associated endoplasmic reticulum membrane (MAMs) dysfunction mediated arsenic (As)-evoked pulmonary ferroptosis and acute lung injury (ALI). As exposure led to alveolar structure damage, inflammatory cell infiltration and pulmonary function decline in mice. Ferritin, the marker of iron overload, was increased, GPX4, the index of lipid peroxidation, was decreased in As-exposed lungs and pulmonary epithelial cells (MLE-12). Pretreatment with ferrostatin-1 (Fer-1), the inhibitor of ferroptosis, alleviated As-evoked ALI. In addition, As-induced non-heme iron deposition was inhibited in Fer-1 pretreated-mice. Moreover, As-triggered mitochondria damage and ferroptosis were mitigated in Fer-1 pretreated-MLE-12 cells. Mechanistically, PERK phosphorylation and mitofusin-2 (Mfn-2) reduction was observed in As-exposed MLE-12 cells and mice lungs. Additionally, the interaction between PERK and Mfn-2 was downregulated and MAMs dysfunction was observed in As-exposed MLE-12 cells. Intriguingly, PERK inhibitor and Mfn-2-overexpression all mitigated As-induced ferroptosis in MLE-12 cells. Additionally, CLPP and mtHSP70, the markers of mitochondrial stress, were upregulated, mitochondrial ROS (mtROS) was elevated, mitochondrial membrane potential (MMP) and ATP were decreased in As-exposed MLE-12 cells. Mitoquinone mesylate (MitoQ), a novel mitochondrial-targeted antioxidant, alleviated As-induced excess mtROS, mitochondrial stress, MAMs dysfunction in pulmonary epithelial cells. Similarly, in vivo experiments indicated that MitoQ pretreatment countered As-induced pulmonary ferroptosis and ALI. These data indicated that mtROS-initiated MAMs dysfunction is, at least partially, implicated in As-evoked ferroptosis and ALI.

Abstract
The optimal oxygen concentration is unclear for normothermic machine perfusion (NMP) of livers from donation after circulatory death (DCD). Our purposes were to investigate the effect of air-ventilated NMP on the DCD liver, analyze the underlying mechanism and select the targets to predict liver functional recovery with NMP. NMP was performed using the NMP system with either air ventilation or oxygen ventilation for 2 h in the rat liver following warm ischemia and cold-storage preservation. Proteomics and metabolomics were used to reveal the significant molecular networks. The bioinformation analysis was validated by administering peroxisome proliferator activator receptor-γ (PPARγ) antagonist and agonist via perfusion circuit in the air-ventilated NMP. Results showed that air-ventilated NMP conferred a better functional recovery and a less inflammatory response in the rat DCD liver; integrated proteomics and metabolomics analysis indicated that intrahepatic docosapentaenoic acid downregulation and upregulation of cytochrome P450 2E1 (CYP2E1) expression and activity were associated with DCD liver functional recovery with air-ventilated NMP; PPARγ antagonist worsened liver function under air-oxygenated NMP whereas PPARγ agonist played the opposite role. In conclusion, air-ventilated NMP confers a better liver function from DCD rats through the DAP-PPARγ-CYP2E1 axis; CYP2E1 activity provides a biomarker of liver functional recovery from DCD.

Acetaminophen (APAP), one of the most widely used antipyretics and analgesics, principally results in acute liver injury (ALI) in developed countries when taken overdose. Ferulic acid (FA) is a natural polyphenol compound existing in many plants that has free radical scavenging, anti-inflammatory and liver-protective properties. However, the effect and underlying mechanism of FA in treating APAP-induced ALI have not been fully elucidated. Herein, we established a mouse model of APAP-induced ALI and used APAP-stimulated mouse primary hepatocytes for biochemical assessment of molecular parameters. After constructing networks and obtaining predicted targets from public databases, we further verified the putative pathways using immune-blotting assays both in vivo and in vitro. The reign of liver necrosis, serum levels of ALT and AST and oxidative stress in livers significantly elevated after APAP treatment, which were almost recovered back to normal levels by FA administration. In addition, FA significantly upregulated the APAP-induced downregulation of hepatic specific markers, including HNF4a, Foxa2 and ALB. Then, the results of functional enrichment indicated the possible signaling pathways of FA against APAP challenge, mainly including AMPK, autophagy, apoptosis and other metabolic process. Furthermore, FA markedly reversed the APAP-induced decline of mitochondria membrane potential, increased ratio of BAX/BCL2 and CASPASE 3 expression, and promoted autophagy flux of hepatocytes by upregulating AMPK phosphorylation, which were abrogated by a specific AMPK inhibitor, compound C. Overall, the hepatoprotective effect of FA on APAP-induced ALI might be associated with anti-oxidant and anti-apoptosis, which were at least partly attributed to AMPK-mediated protective autophagy.

Abstract
Taraxacum syriacum (TS) with natural antioxidant and pharmacological activities may be considered for treatment of oxidative stress induced by acetaminophen (APAP). The aim of this study was to evaluate the ameliorative effects of the ethanol extract of TS root against hepatorenal toxicity induced by APAP in comparison to N-acetylcysteine (NAC) as a standard drug. Thirty male Wistar rats were randomly divided into five groups. Control group; APAP (1 g/kg) group; APAP-NAC (160 mg/kg) group and APAP-TS100 and APAP-TS200 groups: APAP plus 100 and 200 mg/kg of TS extract, respectively. After 7 days treatment, serum and liver and kidney tissues were prepared and evaluated. TS extract ameliorated the increased lipid peroxidation level and decreased antioxidant enzymes activities and glutathione level in liver and kidney of APAP-treated rats. Moreover, treatment with the TS extract caused significant reduction in the histopathological damages and high levels of serum biochemical markers of hepatic and renal functions after APAP treatment. This study suggests that the extract of TS roots has dose-dependent ameliorative effect against APAP-induced oxidative damage in liver and kidney due to its free radical scavenging and antioxidant properties. The overall efficacy of the extract at 200 mg/kg dose is comparable with NAC.

Mol Pharmacol 2021; 100:224-236. [PMID: 34210765 DOI: 10.1124/molpharm.121.000256] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2021] [Accepted: 06/21/2021] [Indexed: 11/22/2022] Open
Abstract
Mounting evidence has revealed that despite the high degree of sequence homology between cytochrome P450 3A isoforms (i.e., CYP3A4 and CYP3A5), they have the propensities to exhibit vastly different irreversible and reversible interactions with a single substrate. We have previously established that benzbromarone (BBR), a potent uricosuric agent used in the management of gout, irreversibly inhibits CYP3A4 via mechanism-based inactivation (MBI). However, it remains unelucidated if CYP3A5-its highly homologous counterpart-is susceptible to inactivation by BBR. Using three structurally distinct probe substrates, we consistently demonstrated that MBI was not elicited in CYP3A5 by BBR. Our in silico covalent docking models and molecular dynamics simulations suggested that disparities in the susceptibilities toward MBI could be attributed to the specific effects of BBR covalent adducts on the F-F' loop. Serendipitously, we also discovered that BBR reversibly activated CYP3A5-mediated rivaroxaban hydroxylation wherein apparent V max increased and K m decreased with increasing BBR concentration. Fitting data to the two-site model yielded interaction factors α and β of 0.44 and 5.88, respectively, thereby confirming heterotropic activation of CYP3A5 by BBR. Furthermore, heteroactivation was suppressed by the CYP3A inhibitor ketoconazole in a concentration-dependent manner and decreased with increasing preincubation time, implying that activation was incited via binding of parent BBR molecule within the enzymatic active site. Finally, noncovalent docking revealed that CYP3A5 can more favorably accommodate both BBR and rivaroxaban in concert as compared with CYP3A4, which further substantiated our experimental observations. SIGNIFICANCE STATEMENT: Although it has been previously demonstrated that benzbromarone (BBR) inactivates CYP3A4, it remains uninterrogated whether it also elicits mechanism-based inactivation in CYP3A5, which shares ∼85% sequence similarity with CYP3A4. This study reported that BBR exhibited differential irreversible and reversible interactions with both CYP3A isoforms and further unraveled the molecular determinants underpinning their diverging interactions. These data offer important insight into differential kinetic behavior of CYP3A4 and CYP3A5, which potentially contributes to interindividual variabilities in drug disposition.

Abstract
Several experiments confirmed that vitamin D3 protected against acetaminophen (APAP)-induced acute liver injury (ALI). This research aimed to evaluate the influence of vitamin D deficiency (VDD) on APAP-induced ALI. In VDD and VDD + APAP groups, mice were fed with VDD diet. In APAP and VDD + APAP groups, mice were intraperitoneally injected with a sublethal dose of APAP (150 mg/kg). A sublethal dose of APAP caused a slight elevation of ALT and AST. Interestingly, APAP-induced elevation of ALT and AST was aggravated in VDD-fed mice. APAP-induced hepatic necrosis was exacerbated in VDD-fed mice. In addition, APAP-induced hepatocyte death, measured using TUNEL assay, was exacerbated in VDD-fed mice. Additional experiment showed that APAP-induced hepatic GSH depletion and lipid peroxidation were exacerbated in VDD-fed mice. Moreover, APAP-induced upregulation of antioxidant genes, such as hepatic heme oxygenase-1 (Ho-1), glutathione peroxidase (Gshpx), superoxide dismutase 1 (Sod1) and catalase enzymes (Cat), was aggravated in VDD-fed mice. Although a sublethal dose of APAP did not cause hepatic inflammation, hepatic proinflammatory cytokines and chemokines, such as Tnf-α, Kc, Mcp-1 and Mip2, were upregulated in VDD-fed mice treated with APAP. These results provide experimental data that VDD exacerbates hepatic oxidative stress and inflammation during APAP-induced ALI.

Abstract
Risk factors related to the development of acetaminophen (APAP)-induced adverse reactions and liver injury remain uncertain. Sleep disorders have been linked to some health outcomes. This study examined the associations of sleep disorders with APAP-induced adverse reactions or liver injury and the possible mechanisms. From NIS database, adverse reactions, liver injury and sleep disorders were identified. Factors associated with the risk of the total adverse effects or liver injury were examined with logistic regression. From Gene Expression Omnibus database, datasets GSE111828, containing transcriptome data based on RNA-seq analysis from liver samples extracted from mice post APAP administration, and GSE92913, containing transcriptome data based on microarray analysis from liver samples extracted from mice with sleep deprivation, were analyzed. A total of 4372754 patients without and 91314 patients with sleep disorders were eligible for analyses. Both before and after propensity score matching, APAP-induced adverse reactions were higher in patients with sleep disorders than in patients without. In multivariate regression, sleep disorders were associated with higher odds of APAP-induced adverse reactions (adjusted OR [aOR] 2.005, 95 % CI 1.343-2.995) and liver injury (aOR 2.788, 95 % CI 1.310-5.932). Genes that were enriched in bile secretion and retinol metabolism and PPAR signaling pathways were basically down-regulated in livers of mice after APAP administration and livers of mice with sleep deprivation. This study shows that sleep disorders may be novel independent risk factors for APAP-associated adverse reactions and liver injury and provides bioinformation linking sleep disorders to increased risk of APAP-induced liver injury.

Abstract
Liver fibrosis is a dynamic wound-healing process associated with the deposition of extracellular matrix produced by myofibroblasts. HSCs activation, inflammation, oxidative stress, steatosis and aging play critical roles in the progression of liver fibrosis, which is correlated with the regulation of the peroxisome proliferator-activated receptor (PPAR) pathway. As nuclear receptors, PPARs reduce inflammatory response, regulate lipid metabolism, and inhibit fibrogenesis in the liver associated with aging. Thus, PPAR ligands have been investigated as possible therapeutic agents. Mounting evidence indicated that some PPAR agonists could reverse steatohepatitis and liver fibrosis. Consequently, targeting PPARs might be a promising and novel therapeutic option against liver fibrosis. This review summarizes recent studies on the role of PPARs on the pathogenesis and treatment of liver fibrosis.

Omega-3 fatty acids protect against acetaminophen-induced hepatic and renal toxicity in rats through HO-1-Nrf2-BACH1 pathway. Arch Biochem Biophys 2020; 687:108387.

Abstract
Although acetaminophen (APAP) is a commonly used analgesic antipyretic drug, hepatotoxicity and nephrotoxicity are common after the overdose. The main mechanism of APAP toxicity is oxidative stress based. Stress may induce the production of heme oxygenase 1 (HO)-1 which is regulated by interleukin (IL)-10 and inhibit the production of tumor necrosis factor-alpha (TNF-α). HO-1 expression is further regulated by nuclear factor erythroid 2-related factor 2 (Nrf2) and the transcription factor BTB and CNC homology 1 (BACH1). Drug-induced toxicity can be relieved by several natural products, which are preferred due to their dietary nature and less adverse reactions. Of these natural products, omega-3 (ω-3) fatty acids are known for anti-inflammatory and antioxidant actions. However, effects of ω-3fatty acids on APAP-induced hepatic and renal toxicity are not well addressed. We designed this study to test the potential protecting actions of ω-3 fatty acids (270 mg/kg Eicosapentaenoic acid and 180 mg/kg docosahexaenoic acid, orally, for 7 days) in hepatotoxicity and nephrotoxicity induced by APAP (2 g/kg, once orally on day 7) in rats. Moreover, we focused on the molecular mechanism underlying APAP hepatotoxicity and nephrotoxicity. Pre-treatment with ω-3 fatty acids enhanced liver and kidney functions indicated by decreased serum aminotransferases activities and serum creatinine and urea concentrations. These results were further confirmed by histopathological examination. Moreover, ω-3 fatty acids showed antioxidant properties confirmed by decreased malondialdehyde level and increased total antioxidant capacity. Antioxidant Nrf2, its regulators (HO-1 and BACH1) and the anti-inflammatory cytokine (IL-10) were up-regulated by APAP administration as a compensatory mechanism and they were normalized by ω-3 fatty acids. ω-3 fatty acids showed anti-inflammatory actions through down-regulating nuclear factor kappa B (NF-ĸB) and its downstream TNF-α. Moreover, Western blot analysis showed that ω-3 fatty acids promoted Nrf2 translocation to the nucleus; BACH1 exit from the nucleus and inhibited NF-ĸB nuclear translocation. These findings suggested the protecting actions of ω-3 fatty acids against APAP-induced hepatic and renal toxicity through regulation of antioxidant Nrf2 and inflammatory NF-ĸB pathways.

Abstract
Background & Aims Endothelial precursor cell (EPC) dysfunction is one of the risk factors for diabetes mellitus (DM) which results in delayed wound healing. Rosiglitazone (RSG) is a frequently prescribed oral glucose-lowering drug. Previous studies have shown the positive effects of RSG on ameliorating EPC dysfunction in diabetic patients. Interestingly, knowledge about RSG with regard to the wound healing process caused by DM is scarce. Therefore, in this study, we investigated the possible actions of RSG on wound healing and the related mechanisms involved in db/db diabetic mice. Methods Db/db mice with spontaneous glucose metabolic disorder were used as a type 2 DM model. RSG (20 mg/kg/d, i.g.,) was administered for 4 weeks before wound creation and bone marrow derived EPC (BM-EPC) isolation. Wound closure was assessed by wound area and CD31 staining. Tubule formation and migration assays were used to judge the function of the BM-EPCs. The level of vascular endothelial growth factor (VEGF), stromal cell derived factor-1α (SDF-1α) and insulin signaling was determined by ELISA. Cell viability of the BM-EPCs was measured by CCK-8 assay. Results RSG significantly accelerated wound healing and improved angiogenesis in db/db mice. Bioactivities of tube formation and migration were decreased in db/db mice but were elevated by RSG. Level of both VEGF and SDF-1α was increased by RSG in the BM-EPCs of db/db mice. Insulin signaling was elevated by RSG reflected in the phosphorylated-to-total AKT in the BM-EPCs. In vitro, RSG improved impaired cell viability and tube formation of BM-EPCs induced by high glucose, but this was prevented by the VEGF inhibitor avastin. Conclusion Our data demonstrates that RSG has benefits for wound healing and angiogenesis in diabetic mice, and was partially associated with improvement of EPC function through activation of VEGF and stimulation of SDF-1α in db/db mice.

Abstract
AIMS We previously reported that Hovenia dulcis Thunb. extract, a traditional Chinese medicine rich in dihydromyricetin (DHM), exhibited a significant hepatoprotective effect against acetaminophen (APAP)-induced liver injury. However, whether DHM plays a protective role in APAP hepatotoxicity and what mechanisms are involved remain unclear. In this study, we evaluated the hepatoprotective effects of DHM against APAP-induced liver injury. MAIN METHODS Male C57BL/6 mice were used for the experiment. LC-MS, q-PCR, immunochemistry and western blot analysis were employed to mechanism analysis. KEY FINDINGS DHM exhibited a protective effect against APAP-induced liver injury. Further mechanistic investigations revealed that the protective effect of DHM against APAP hepatotoxicity had multi-target and multi-pathway characteristics involving APAP metabolism, lipid regulation, and hepatocyte death and regeneration. DHM pretreatment resulted in cytochrome P450 2E1 inhibition and UDP-glucuronosyltransferase 1A1 activation, affecting APAP biotransformation. Moreover, DHM pretreatment significantly ameliorated lipid dysregulation via peroxisome proliferator-activated receptor and sterol regulatory element-binding protein-1c (SREBP-1c) signalling pathways. Furthermore, DHM regulated the expression of cell death- and liver regeneration-associated proteins. SIGNIFICANCE These results suggested that DHM alleviated APAP-induced liver injury in mice by inhibiting hepatocyte death, promoting p53-related regeneration, and regulating lipid homeostatic imbalance and APAP transformation. Based on these findings, DHM provides a potential and novel approach for preventing and treating APAP-induced liver damage, and SREBP-1c signalling might be a new therapeutic target for APAP hepatotoxicity.

[PMID: 30602693 PMCID: PMC6337302 DOI: 10.3390/molecules24010131] [Citation(s) in RCA: 42] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 12/21/2018] [Accepted: 12/26/2018] [Indexed: 12/25/2022] Open
Abstract
Baicalein (BAI), one of the main components of Scutellaria baicalensis Georgi, possesses numerous pharmacological properties, including anti-cancer, anti-oxidative, anti-virus and anti-bacterial activities. The purpose of this study was to evaluate the hepatoprotective effect of baicalein against acetaminophen (APAP)-exposed liver injury in mice, and elucidate the underlying hepatoprotective mechanism. Baicalein pretreatment significantly alleviated the elevation of IL-6, IL-1β and TNF-α in serum and hepatic in a dose-dependent manner. It also dose-dependently reduced the hepatic malondialdehyde (MDA) concentration, as well as the depletion of hepatic superoxide dismutase (SOD), hepatic glutathione (GSH) and hepatic catalase (CAT). Moreover, pretreatment with baicalein significantly ameliorated APAP-exposed liver damage and histological hepatocyte changes. Baicalein also relieved APAP-induced autophagy by regulating AKT/mTOR pathway, LC3B and P62 expression. Furthermore, the hepatoprotective effect of baicalein to APAP-induced liver injury involved in Jak2/Stat3 and MAPK signaling pathway. Taken together, our findings suggested that baicalein exhibits the ability to prevent liver from APAP-induced liver injury and provided an underlying molecular basis for potential applications of baicalein to cure liver injuries.

Abstract
The accurate prediction of hepatotoxicity demands validated human in vitro models that can close the gap between preclinical animal studies and clinical trials. In this study we investigated the response of primary human liver cells to toxic drug exposure in a perfused microscale 3D liver bioreactor. The cellularized bioreactors were treated with 5, 10, or 30 mM acetaminophen (APAP) used as a reference substance. Lactate production significantly decreased upon treatment with 30 mM APAP (p < 0.05) and ammonia release significantly increased in bioreactors treated with 10 or 30 mM APAP (p < 0.0001), indicating APAP-induced dose-dependent toxicity. The release of prostaglandin E2 showed a significant increase at 30 mM APAP (p < 0.05), suggesting an inflammatory reaction towards enhanced cellular stress. The expression of genes involved in drug metabolism, antioxidant reactions, urea synthesis, and apoptosis was differentially influenced by APAP exposure. Histological examinations revealed that primary human liver cells in untreated control bioreactors were reorganized in tissue-like cell aggregates. These aggregates were partly disintegrated upon APAP treatment, lacking expression of hepatocyte-specific proteins and transporters. In conclusion, our results validate the suitability of the microscale 3D liver bioreactor to detect hepatotoxic effects of drugs in vitro under perfusion conditions.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2018; 25:3468-3479. [PMID: 29152699 DOI: 10.1007/s11356-017-0750-3] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/20/2017] [Accepted: 11/14/2017] [Indexed: 06/07/2023]
Abstract
This study aimed to investigate the possible protective role of curcumin (CUR) vs. N-acetyl cysteine (NAC) against paracetamol (PCM)-induced oxidative damage and impairment of liver, kidney, and testicular functions, as well as hematotoxicity, in albino rats. A large single dose of PCM induced lipid peroxidation along with a significant decline in glutathione content and catalase activity in the liver, kidneys, and testicles. The apparent oxidative damage was associated with evident hepatic, renal, and testicular dysfunction, which was confirmed in histopathological lesions, and increased serum aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase activities. PCM decreased serum total protein, albumin, and globulin contents; increased bilirubin, urea, and creatinine contents; and induced hematotoxicity. PCM also reduced the sperm cell count, sperm motility, and alive sperm rate and increased the sperm abnormality rate. Pretreatment of PCM-intoxicated animals with CUR or NAC substantially alleviated the increase in malondialdehyde and maintained the antioxidants at control levels. These pretreatments also minimized liver, kidney, and testicular histopathological changes and normalized their functions. CUR similarly mitigated the PCM hemato- and hepatotoxicity compared with NAC. However, it exhibited a pronounced nephroprotection, rather than reproductive protection as did NAC. Our findings demonstrate that a large single dose of PCM is not only associated with hepatotoxicity but also nephrotoxicity and reproductive toxicity. Both CUR and NAC administration provided substantial organ protection with pronounced efficacy against PCM nephrotoxicity with CUR and reproductive toxicity with NAC, which was possibly mediated through their antioxidant activities, as well as their specific characteristics.

Abstract
BACKGROUND Acetaminophen (APAP) is a readily available and safe painkiller. However, its overdose is the most common cause of acute liver injury (ALI). Many predisposing factors contribute to susceptibility to APAP-induced ALI. Non-alcoholic fatty liver disease (NAFLD), the major cause of chronic liver disease, is considered an important predictor of APAP-induced ALI, although the exact mechanism controversial. In this study, we aimed to elucidate the effects of NAFLD on APAP-induced ALI. METHODS Two groups of mice, normal chow (NC) diet-fed and fast food (FF) diet-fed mice for 14 weeks, were further divided into two subgroups: intraperitoneally injected with either saline (NC-S and FF-S groups) or APAP (NC-A and FF-A groups). Biochemical tests, histological analysis, quantitative PCR, and western blotting were conducted. RESULTS Alanine aminotransferase (ALT) level (199.0 ± 39.0 vs. 63.8 ± 7.4 IU/L, p < 0.05) and NAFLD activity score (0 vs. 4.5 ± 0.22) were significantly higher in mice in FF-S group than those in NC-S group. ALI features such as ALT level (8447.8 ± 1185.3 vs. 836.6 ± 185.1 IU/L, p < 0.001) and centrizonal necrosis were prominent and mRNA levels of Trib3 (RR, 1.81) was high in mice in the NC-A group. Levels of CYP2E1 and anti-inflammatory molecules such as PPAR-γ, p62, and NRF2 were high in mice in the FF-A group. CONCLUSIONS Our results showed that while the FF diet clearly induced non-alcoholic steatohepatitis and metabolic syndrome, NAFLD also attenuates APAP-induced ALI by inducing anti-inflammatory molecules such as PPAR-γ.

Biochemical targets of drugs mitigating oxidative stress via redox-independent mechanisms. Biochem Soc Trans 2017; 45:1225-1252. [PMID: 29101309 DOI: 10.1042/bst20160473] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2017] [Revised: 09/24/2017] [Accepted: 09/26/2017] [Indexed: 12/13/2022]
Abstract
Acute or chronic oxidative stress plays an important role in many pathologies. Two opposite approaches are typically used to prevent the damage induced by reactive oxygen and nitrogen species (RONS), namely treatment either with antioxidants or with weak oxidants that up-regulate endogenous antioxidant mechanisms. This review discusses options for the third pharmacological approach, namely amelioration of oxidative stress by 'redox-inert' compounds, which do not inactivate RONS but either inhibit the basic mechanisms leading to their formation (i.e. inflammation) or help cells to cope with their toxic action. The present study describes biochemical targets of many drugs mitigating acute oxidative stress in animal models of ischemia-reperfusion injury or N-acetyl-p-aminophenol overdose. In addition to the pro-inflammatory molecules, the targets of mitigating drugs include protein kinases and transcription factors involved in regulation of energy metabolism and cell life/death balance, proteins regulating mitochondrial permeability transition, proteins involved in the endoplasmic reticulum stress and unfolded protein response, nuclear receptors such as peroxisome proliferator-activated receptors, and isoprenoid synthesis. The data may help in identification of oxidative stress mitigators that will be effective in human disease on top of the current standard of care.
