Abstract
AbstractPrevious studies suggest that activation of SIRT1 protects liver from acetaminophen (APAP)-induced injury; however, the detailed mechanism of SIRT1 modulation in this process is still incomplete. Therefore, this study was to investigate the pathophysiological role of SIRT1 in APAP-mediated hepatotoxicity. We found that SIRT1 mRNA and protein were markedly upregulated in human LO2 cells and mouse liver upon APAP exposure. In vitro, the specific knockdown of SIRT1 expression ultimately aggravated APAP-evoked cellular antioxidant defense in LO2 cells. Moreover, lentivirus-mediated knockdown of hepatic SIRT1 expression exacerbated APAP-induced oxidative stress and liver injury, especially reduction of Nrf2 and subsequent downregulation of several antioxidant genes. Intriguingly, 30 mg/kg SRT1720, the specific SIRT1 activator, which greatly enhanced Nrf2 expression and antioxidant defense, and then eventually reversed APAP-induced hepatic liver injury in mice. Furthermore, APAP responsive miR-19b played an important role in regulating SIRT1 expression, whereas overexpression miR-19b largely abolished the induction of SIRT1 by APAP in vitro and in vivo. Specific SIRT1 3′-UTR mutation, which disrupted the interaction of miRNA-3′UTR, and successfully abrogated the modulation by miR-19b. Notably, hepatic miR-19b overexpression worsened the APAP-induced hepatotoxicity. In general, our results support the notion that the strong elevation of SIRT1 by APAP responsive miR-19b may represent a compensatory mechanism to protect liver against the drug-induced damage, at least in part by enhancing Nrf2-mediated antioxidant capacity in the liver.

Abstract
BACKGROUND AND AIM Overdose of acetaminophen (APAP) leads to liver injury, which is one of the most common causes of liver failure in the United States. We previously demonstrated that pharmacological activation of autophagy protects against APAP-induced liver injury in mice via removal of damaged mitochondria and APAP-adducts (APAP-ADs). Using an image-based high-throughput screening for autophagy modulators, we recently identified that chlorpromazine (CPZ), a dopamine inhibitor used for anti-schizophrenia, is a potent autophagy inducer in vitro. Therefore, the aim of the present study is to determine whether CPZ may protect against APAP-induced liver injury via inducing autophagy. METHODS Wild type C57BL/6J mice were injected with APAP to induce liver injury. CPZ was administrated either at the same time with APAP (co-treatment) or 2 h later after APAP administration (post-treatment). Hemotoxyline and eosin (H&E) staining of liver histology, terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end labeling (TUNEL) staining of necrotic cell death as well as serum levels of alanine aminotransferase (ALT) were used to monitor liver injury. RESULTS We found that CPZ markedly protected against APAP-induced liver injury as demonstrated by decreased serum levels of ALT, liver necrotic areas as well as TUNEL-positive cells in mice that were either co-treated or post-treated with CPZ. Mechanistically, we observed that CPZ increased the number of autolysosomes and decreased APAP-induced c-Jun N-terminal kinase activation without affecting the metabolic activation of APAP. Pharmacological inhibition of autophagy by chloroquine partially weakened the protective effects of CPZ against APAP-induced liver injury. CONCLUSIONS Our results indicate that CPZ ameliorates APAP-induced liver injury partially via activating hepatic autophagy and inhibiting JNK activation.

Abstract
Acetaminophen (APAP) is a widely used analgesic and antipyretic drug that leads to severe hepatotoxicity at excessive doses. Fucoidan, a sulfated polysaccharide derived from brown seaweeds, possesses a wide range of pharmacological properties. However, the impacts of fucoidan on APAP-induced liver injury have not been sufficiently addressed. In the present study, male Institute of Cancer Research (ICR) mice aged 6 weeks were subjected to a single APAP (500 mg/kg) intraperitoneal injection after 7 days of fucoidan (100 or 200 mg/kg/day) or bicyclol intragastric administration. The mice continued to be administered fucoidan or bicyclol once per day, and were sacrificed at an indicated time. The indexes evaluated included liver pathological changes, levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in the serum, levels of reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione (GSH) and catalase (CAT) in the liver, and related proteins levels (CYP2E1, pJNK and Bax). Furthermore, human hepatocyte HL-7702 cell line was used to elucidate the potential molecular mechanism of fucoidan. The mitochondrial membrane potential (MMP) and nuclear factor-erythroid 2-related factor (Nrf2) translocation in HL-7702 cells were determined. The results showed that fucoidan pretreatment reduced the levels of ALT, AST, ROS, and MDA, while it enhanced the levels of GSH, SOD, and CAT activities. Additionally, oxidative stress-induced phosphorylated c-Jun N-terminal protein kinase (JNK) and decreased MMP were attenuated by fucoidan. Although the nuclear Nrf2 was induced after APAP incubation, fucoidan further enhanced Nrf2 in cell nuclei and total expression of Nrf2. These results indicated that fucoidan ameliorated APAP hepatotoxicity, and the mechanism might be related to Nrf2-mediated oxidative stress.

Abstract
Sirtuin3 (SIRT3) plays an important role in maintaining normal mitochondrial function and alleviating oxidative stress. After carbon tetrachloride (CCl4 ) administration, the expression of SIRT3 decreased in the liver of mice, which indicated that the SIRT3 might play a crucial role during chemical-induced acute hepatic injury. To verify the hypothesis, CCl 4 was given to induce acute hepatic injury in SIRT3 knockout (KO) mice and wild-type (WT) mice. CCl 4 -induced liver injury was more severe in SIRT3 KO mice compared with the WT mice. In addition, the oxidative stress induced by CCl 4 was enhanced in the SIRT3 KO mice. Furthermore, the increased expression of dynamin-related protein 1 was also aggravated in SIRT3 KO mice after CCl 4 administration. In conclusion, our study demonstrated that SIRT3 deficiency exacerbated CCl 4 -induced impairment of the liver in mice, and the mechanism might be related to enhanced oxidative stress.

Carbon monoxide releasing molecule A-1 attenuates acetaminophen-mediated hepatotoxicity and improves survival of mice by induction of Nrf2 and related genes. Toxicol Appl Pharmacol 2018; 360:99-108.

Abstract
Acute liver injury is frequently associated with oxidative stress. Here, we investigated the therapeutic potential of carbon monoxide releasing molecule A-1 (CORM A-1) in oxidative stress-mediated liver injury. Overnight-fasted mice were injected with acetaminophen (APAP; 300 mg/kg; intraperitoneally) and were sacrificed at 4 and 12 h. They showed elevated levels of serum transaminases, depleted hepatic glutathione (GSH) and hepatocyte necrosis. Mice injected with CORM A-1 (20 mg/kg) 1 h after APAP administration, had reduced serum transaminases, preserved hepatic GSH and reduced hepatocyte necrosis. Mice that received a lethal dose of APAP (600 mg/kg), died by 10 h; but those co-treated with CORM A-1 showed a 50% survival. Compared to APAP-treated mice, livers from those co-treated with CORM A-1, had upregulation of Nrf2 and ARE genes (HO-1, GCLM and NQO-1). APAP-treated mice had elevated hepatic mRNA levels of inflammatory genes (Nf-κB, TNF-α, IL1-β and IL-6), an effect blunted in those co-treated with CORM A-1. In tert-butyl hydroperoxide (t-BHP)-treated HepG2 cells, CORM A-1 augmented cell viability, reduced oxidative stress, activated the nuclear factor erythroid 2-related factor 2 (Nrf2) and anti-oxidant response element (ARE) genes. The molecular docking profile of CO in the kelch domain of Keap1 protein suggested that CO released from CORM A-1 mediated Nrf2 activation. Collectively, these data indicate that CORM A-1 reduces oxidative stress by upregulating Nrf2 and related genes, and restoring hepatic GSH, to reduce hepatocyte necrosis and thus minimize liver injury that contributes to an overall improved survival rate.

J Clin Pharmacol 2018; 59:131-138.

Abstract
Acetaminophen (APAP)-induced liver injury is initiated by metabolism of APAP by the cytochrome P-450 (CYP) system, primarily CYP2E1. We previously demonstrated CYP inhibition following administration of a liquid APAP formulation containing propylene glycol, a CYP2E1 inhibitor, and other excipients. This study was undertaken to determine if propylene glycol specifically inhibits production of CYP-derived metabolites and if propylene glycol reduces the rise in alanine aminotransferase (ALT) seen following prolonged APAP dosing. Human subjects were randomized to receive 4 g of APAP daily in one arm of the study or 4 g of APAP with 5 mL of 99% propylene glycol in the other arm, both for 14 days. After a washout period of at least 14 days, subjects were crossed over between arms. Outcomes were rise of ALT greater than 2 times baseline (responders) and proportion of randomly sampled CYP-derived metabolites relative to total metabolites produced. There was no difference in percentage of responders between treatment groups: 6 of 21 in the APAP group (29%) compared with 8 of 20 in the APAP + propylene glycol group (40%); chi-square, P = .59. For all subjects, the mean percentage of CYP-derived metabolites produced was 5.8% (APAP) versus 4.3% (APAP + propylene glycol); P = .018. This effect was solely attributable to the responders: the mean percentage of CYP metabolites of responders was 7.7% (APAP) versus 4.6% (APAP + propylene glycol), P = .050, whereas there was no difference for the nonresponders. Five subjects were responders in both arms (2% probability of random occurrence). Our data indicates that propylene glycol inhibits CYP2E1 metabolism of APAP in some subjects but does not effect hepatocellular indury at the dose given.
