Determination of hepatotoxic drugs is critical for both clinical diagnosis and quantity control of their pharmaceutical formulations. In this work, a facile and sensitive sensor based on MXene modified screen-printed electrode (MXene/SPE) has been developed for detection of acetaminophen (ACOP) and isoniazid (INZ), which are two commonly used drugs but might induce liver damage in certain circumstances. MXene showed excellent electrocatalytic activity toward the oxidation of ACOP and INZ compared with bare SPE in 0...

During a randomized Phase 1 clinical trial the drug candidate, PF-04895162 (ICA-105665), caused transaminase elevations (≥grade 1) in six of eight healthy subjects treated at 300 mg twice daily for 2-weeks (NCT01691274). This was unexpected since studies in rats (<6 months) and cynomolgus monkeys (<9 months) treated up to 100 mg/kg/day did not identify the liver as a target organ. Mechanistic studies showed PF-04895162 had low cytotoxic potential in human hepatocytes, but inhibited liver mitochondrial function and bile salt export protein (BSEP) transport...

A combination therapy of multiple drugs including isoniazid, rifampicin, ethambutol and pyrazinamide has been proven to be an effective option for the vast majority of tuberculosis (TB) patients. However, various adverse drug reactions (ADRs) limit its merit, with anti-TB drug-induced hepatotoxicity (ATDH) being a common and sometimes severe ADR. This study aimed to investigate the association between polymorphisms in two nuclear receptor genes, pregnane X receptor (PXR) and constitutive androstane receptor (CAR), and the risk of ATDH in a Chinese population...

Exposure to high doses of acetaminophen is the most common cause of drug induced liver injury. We investigated the protective effects of Hedera helix extract against acetaminophen induced oxidative stress and hepatotoxicity using a mouse model. We used two control groups: group A was given 0.9% NaCl, group B was an acetaminophen control that was given a single injection of 600 mg/kg acetaminophen. T1-T4 groups were pretreated orally with different doses of H. helix extract. The mice were sacrificed and blood samples were collected to estimate the levels of glutathione peroxidase (GPx), malondialdehyde (MDA), superoxide dismutase (SOD) and total bilirubin...

WHAT IS KNOWN AND OBJECTIVE: Reactive metabolites from anti-tuberculosis (anti-TB) drugs can result in abnormal accumulation of reactive oxygen species (ROS), which plays an important role in anti-TB drug-induced liver injury (ATLI). Liver cells could keep the production of ROS in balance by antioxidant activities. The heme oxygenase 1, encoded by the HMOX1 gene and NADH:quinone oxidoreductase 1, encoded by the NQO1 gene are crucial mediators of cellular defense against ROS. The present study aimed to investigate the associations between HMOX1 and NQO1 polymorphisms and ATLI in Chinese anti-TB treatment population...

Synthetic drugs are associated with adverse side-effects and rapid increase in resistance to most of them inspires to evaluate plants for their therapeutic values. We have been aimed to suggest the medicinal use of Nigella sativa seed aqueous extract to minimize the severity of liver damage via its antioxidant properties and its role in maintenance of cell ion-homeostasis. Annoyances in serum levels of some antioxidants and trace metals in human hepatitis C infected patients were compared with that from acetaminophen-induced hepatotoxic rabbits...

The DILI-sim Initiative is a public-private partnership involving scientists from industry, academia and the FDA. The Initiative uses Quantitative Systems Toxicology (QST) to build and refine a model (DILIsym® ) capable of understanding and predicting liver safety liabilities in new drug candidates and to optimize interpretation of liver safety biomarkers used in clinical studies. Insights gained to date include the observation that most dose-dependent hepatoxicity can be accounted for by combinations of just three mechanisms (oxidative stress, interference with mitochondrial respiration, and alterations in bile acid homeostasis) and the importance of non-competitive inhibition of bile acid transporters...

HepaRG is a proliferative human hepatoma-derived cell line that can be differentiated into hepatocyte-like and biliary-like cells. Differentiated HepaRG cultures maintain key hepatic functions including drug transporters and xenobiotic-metabolizing enzymes. To gain insight into proliferative and differentiated HepaRG metabolism we profiled various bioenergetic parameters and investigated cell culture levels of adenosine triphosphate (ATP), lactate, and lactate dehydrogenase (LDH) activity. Compared to differentiated-derived HepaRG, cells from proliferative cultures had increased basal and ATP-linked respiration and decreased maximal and spare respiratory capacities...

OBJECTIVE: Antituberculosis (anti-TB) drug-induced hepatotoxicity (ATDH) is a serious adverse drug reaction, and its pathogenic mechanism has not been elucidated thoroughly to date. A recent genome-wide association study reported that seven single-nucleotide polymorphisms (SNPs) in the family with sequence similarity 65, member B gene (FAM65B), ATP/GTP-binding protein-like 4 gene (AGBL4), and cut-like homeobox 2 gene (CUX2) were associated strongly with ATDH in Ethiopian patients. We validated this relationship in a Chinese Han anti-TB treatment population...

In this study, syringic acid-loaded TPGS liposome (SA-TPGS-Ls) was successfully prepared to improve oral bioavailability of syringic acid (SA). SA is a natural and notable antioxidant activity compound with its limited bioavailability ascribable to its poor aqueous solubility and fast elimination. Recently, TPGS has become a perfect molecular biomaterial in developing several carrier systems with sustained, controlled, and targeted the drug delivery. SA-TPGS-Ls was prepared via thin-film dispersion method and characterized in terms of particle size, stability, morphology, and encapsulation efficiency (EE)...

Carbon monoxide (CO) acts as an important gasotransmitter in delivering intramolecular and intermolecular signals to regulate a variety of physiological processes. This lipid-soluble gas can freely pass through the cell membrane and then diffuse to adjacent cells acting as a messenger. Although many fluorescent probes have been reported to detect intracellular CO, it is still a challenge to visualize the release behavior of endogenous CO. The main obstacle is the lack of a probe that can anchor onto the cell membrane while having the ability to image CO in real time...

Mannan-binding lectin (MBL) acts as a soluble pattern recognition molecule in the innate immune system, which is primarily produced by the liver. MBL deficiency occurs with high frequency in the population and is reported to be associated with susceptibility to several liver diseases. In the present study, we investigated the pathophysiological role of MBL in acetaminophen (APAP)-induced hepatotoxicity. After APAP treatment, MBL-deficient (MBL-/- ) mice had significantly higher mortality and aggravated hepatic necrosis as well as elevated serum lactate dehydrogenase and alanine aminotransferase levels compared to control mice...

Acetaminophen (APAP) induced liver injury is clinically significant, and APAP overdose in mice often serves as a model for drug-induced liver injury in humans. By specifying that APAP metabolism, reactive metabolite formation, glutathione depletion, and mitigation of mitochondrial damage within individual hepatocytes are functions of intralobular location, an earlier virtual model mechanism provided the first concrete multi-attribute explanation for how and why early necrosis occurs close to the central vein (CV)...

Methotrexate (MTX) is a widely used drug for treatment of many malignant, rheumatic, and autoimmune diseases. However, hepatotoxicity remains one of the most serious side effects of MTX. The extrinsic coagulation pathway is activated after tissue injury through the release of tissue factor (TF) which activates a cascade of clotting factors including prothrombin and fibrinogen. Liver sinusoidal endothelial cells express endothelial nitric oxide synthase (eNOS) as a source for nitric oxide (NO) that serves as vasodilator and antithrombotic factor...

Lipopolysaccharide (LPS) as the major component of the outer membrane of Gram-negative bacteria activates macrophages to produce a high level of pro-inflammatory cytokines which is considered as a cause of liver dysfunction. Overproduction of nitric oxide (NO) has been suggested to have a role in hepatic injury. The aim of the present study was to explore the protective effects of aminoguanidine (AG) as inducible nitric oxide synthase (iNOS) inhibitor against LPS -induced liver dysfunction in rat. The animals were divided into five groups: (1) control (2) LPS (3) LPS-AG50, (4) LPS-AG100 and (5) LPS-AG150...

Immune checkpoint inhibitors (ICIs) block cytotoxic T lymphocyte antigen 4 (CTLA-4) and programmed cell death protein 1 (PD-1)/PD ligand 1 (PD-L1) receptors that control antitumor activities of lymphocytes. While highly efficacious, these drugs have been associated with several immune-related adverse events (irAEs) due to the disruption of self-tolerance. Immune-mediated hepatitis (IMH) usually presents as mild elevations of liver enzymes though it can rarely be associated with life-threatening hepatic injury...
