BACKGROUND: Human hepatocellular carcinoma (HCC) has a high rate of tumor recurrence and metastasis, resulting in shortened survival time. The aim of this study is to evaluate the synergistic anti-tumor effects and underlying mechanism of κ-selenocarrageenan (KSC) in combination with the chemotherapy drug epirubicin (EPI) in H22 tumor-bearing mice. METHODS: Hepatocellular carcinoma H22 cells were implanted into mice. After the transplants were successfully established, the animals were divided into four groups: namely the control group, the KSC group, the EPI group and the KSC+EPI group...

The liver disease related to chronic alcohol consumption is one of the leading causes of death for alcoholics. The efficient drug to ameliorate the alcoholic liver injury was needed urgently. The present study was performed to investigate whether artemisinin possessed the protective effect against chronic alcohol consumption. 50 male Kunming mice were divided into 5 groups: control group (C): 10ml/kg saline+10ml/kg saline, alcohol group (A): 10ml/kg 56%(v/v) alcohol+10ml/kg saline, low dose group of artemisinin (L): 10ml/kg 56%(v/v) alcohol+30mg/kg/day artemisinin, medium dose group of artemisinin (M): 10ml/kg 56%(v/v) alcohol+60mg/kg/day artemisinin, high dose group of artemisinin (H): 10ml/kg 56%(v/v) alcohol+120mg/kg/day artemisinin...

The liver and the kidney are the most common targets of chemical toxicity, due to their major metabolic and excretory functions. However, since the liver is directly involved in biotransformation, compounds in many currently and normally used drugs could affect it adversely. Most chemical compounds are already labeled according to FDA-approved labels using DILI-concern scale. Drug Induced Liver Injury (DILI) scale refers to an adverse drug reaction. Many compounds do not exhibit hepatotoxicity at early stages of development, so it is important to detect anomalies at gene expression level that could predict adverse reactions in later stages...

It is now apparent that antigen-specific T-cells are activated in certain patients with drug-induced liver injury (DILI). Since cross-talk between hepatocytes and immune cells is likely to be critical in determining the outcome of drug exposure, the aim of this study was to profile the signals released by drug-treated hepatocytes and to characterise the impact of these molecules on dendritic cells. Human hepatocytes were exposed to three drugs (flucloxacillin, amoxicillin and isoniazid) associated with DILI potentially mediated by the adaptive immune system as drug-specific T-cells have been isolated from DILI patients, and the metabolite nitroso-sulfamethoxazole (SMX-NO)...

Interest in drug-induced liver injury (DILI) has dramatically increased over the past decade, and it has become a hot topic for clinicians, academics, pharmaceutical companies and regulatory bodies. By investigating the current state of the art, the latest scientific findings, controversies, and guidelines, this review will attempt to answer the question: Do we know everything? Since the first descriptions of hepatotoxicity over 70 years ago, more than 1000 drugs have been identified to date, however, much of our knowledge of diagnostic and pathophysiologic principles remains unchanged...

Reported hepatotoxicity induced by corticosteroids is very rare, and the diagnosis is highly challenging in the context of auto-immune disease. We report here a case of high-dose methylprednisolone (MP)-induced acute hepatitis confirmed by liver histology in a patient with multiple sclerosis (MS) and a case series (n=4) notified to the French Pharmacovigilance center of Lyon. In all 5 cases, other common causes of hepatitis were excluded. The causal relationship with MP pulse therapy was supported by the fact that MP was the only culprit drug...

Drug liver-induced injury (DILI) due to minocyclin, alpha methyldopa or nitrofurantoin may be responsible for chronic liver damage that mimic the biological and/or histological features of chronic autoimmune hepatitis and, in rare cases, progresses to cirrhosis(1). Olmesartan medoxomil is an antihypertensive drug that acts by blocking the angiotensin II receptor and is metabolized into its pharmacologically active form, olmesartan, in the intestine and in the liver before being released into the systemic circulation...

The role of bile salt export protein (BSEP) inhibition in drug-induced liver injury (DILI) has been investigated widely, while inhibition of the canalicular multidrug resistant protein 3 (MDR3) has received less attention. This transporter plays a pivotal role in secretion of phospholipids into bile and functions coordinately with BSEP to mediate the formation of bile acid-containing biliary micelles. Therefore, inhibition of MDR3 in human hepatocytes was examined across 125 drugs (70 of Most- and 55 of No-DILI-concern)...

Drug-induced liver injury (DILI) is a major safety issue during drug development, as well as the most common cause for the withdrawal of drugs from the pharmaceutical market. The identification of DILI biomarkers is a labor-intensive area. Conventional biomarkers are not specific and often only appear at significant levels when liver damage is substantial. Therefore, new biomarkers for early identification of hepatotoxicity during the drug discovery process are needed, thus resulting in lower development costs and safer drugs...

Hepatic solute transport is a complex process whose disruption is associated with liver disease and drug-induced liver injury. Intravital multiphoton fluorescence excitation microscopy provides the spatial and temporal resolution necessary to characterize hepatic transport at the level of individual hepatocytes in vivo and thus to identify the mechanisms and cellular consequences of cholestasis. Here we present an overview of the use of fluorescence microscopy for studies of hepatic transport in living animals, and describe how we have combined methods of intravital microscopy and digital image analysis to dissect the effects of drugs and pathological conditions on the function of hepatic transporters in vivo...

Acetaminophen (APAP) overdose is one of the most common inducements of drug-induced liver injury (DILI) in the world. The main purpose of this paper was to investigate the liver protection activity of saponins (ginsenosides) from the leaves of Panax quinquefolius (PQS) against APAP-induced hepatotoxicity, and the involved mechanisms were demonstrated for the first time. Mice were pretreated with PQS (150 and 300 mg/kg) by oral gavage for 7 days before being treated with 250 mg/kg APAP. Severe liver injury was exerted at 24 h post-APAP, and hepatotoxicity was assessed...

INTRODUCTION AND AIMS: Drug-induced liver injury (DILI) is rare; however, it is one of the important causes of acute liver failure which results in significant morbidity or mortality. MATERIAL AND METHODS: Patients with suspected DILI were enrolled based on predefined criteria and followed up for at least 6 months or until normalization of liver tests. Causality assessment was done by applying the Roussel Uclaf Causality Assessment Method model. RESULTS: We collected data from 82 individuals diagnosed with DILI at our hospital from 2014 through 2015 (41 men; median age, 38 years)...

Pyrazinamide (PYZ)-an essential component of primary drug regimen used for the treatment and management of multidrug resistant or latent tuberculosis-is well known for its hepatoxicity. However, the mechanism of PYZ-induced hepatotoxicity is still unknown to researchers. Studies have shown that the drug is metabolized in the liver to pyrazinoic acid (PA) and 5-hydroxy pyrazinoic acid (5-OHPA) which individually may cause different degrees of hepatotoxicity. To evaluate this hypothesis, PYZ, PA, and 5-OHPA were administered to albino Wistar rats orally (respectively, at 250, 125, and 125 mg kg(-1) for 28 days)...

Cimaglermin alfa (GGF2) is a recombinant human protein growth factor in development for heart failure. Phase 1 trials were suspended when 2 cimaglermin alfa-treated subjects experienced concomitant elevations in serum aminotransferases and total bilirubin meeting current FDA criteria for a serious liver safety signal (i.e. "Hy's Law"). We assayed mechanistic biomarkers in archived clinical trial serum samples which confirmed the hepatic origin of the aminotransferase elevations in these two subjects and identified apoptosis as the major mode of hepatocyte death...

In the development of drugs, we sometimes encounter fatty change of the hepatocytes (steatosis) which is not accompanied by degenerative change in the liver in non-clinical toxicity studies. In this study, we investigated the relationships between fatty change of the hepatocytes noted in non-clinical toxicity studies of compound X, a candidate compound in drug development, and mitochondrial dysfunction in order to estimate the potential risk of the compound to induce drug-induced liver injury (DILI) in humans...

BACKGROUND: Radiotherapy is one of the most important modalities in cancer treatment; however, normal tissue damage is a serious concern. Drug development for the protection or reduction of normal tissue damage is therefore a clinical issue. Herein, we evaluated the protective properties of Panax ginseng Meyer and its corresponding mechanisms. METHODS: C56BL/6 mice were orally pretreated with P. ginseng water extract (PGE; 25 mg/kg, 50 mg/kg, or 100 mg/kg) or intraperitoneally injected melatonin (20 mg/kg) for 4 d consecutively, then exposed to 15-Gy X-ray radiation 1 h after the last administration...

Improper usage of unprocessed Radix bupleuri root (chaihu) may cause cardiotoxicity and liver injury. Baking herb with vinegar is believed to attenuate the adverse responses. However, the chemical and molecular basis involved remained unclear. To this end, we investigated the in vitro toxicity of saikosaponin a, c, d, and their hydrolysates saikosaponin b1 and b2. Results showed that SSa and SSd possessed higher affinity with sarcoplasmic/endoplasmic reticulum calcium ATPase (SERCA) by molecular docking, and exhibited stronger toxic responses on cardiomyocytes and hepatocytes than the other three saikosaponins in equivalent concentrations...

Alcoholic liver disease (ALD), a leading cause of chronic liver injury worldwide, comprises a range of disorders including simple steatosis, steatohepatitis, cirrhosis, and hepatocellular carcinoma. Over the last five decades, many animal models that have been useful for the study of ALD pathogenesis have been developed. Recently, a chronic-plus-binge ethanol feeding model was reported. This model induces significant steatosis, hepatic neutrophil infiltration, and liver injury. A clinically relevant model of high-fat diet feeding plus binge ethanol was also developed, which highlights the risk of excessive binge drinking in obese/overweight individuals...

Sepsis, a clinical syndrome occurring in patients following infection or injury, is a leading cause of mortality worldwide. It involves uncontrolled inflammatory response resulting in multi-organ failure and even death. Isoalantolactone (IAL), a sesquiterpene lactone, is known for its anti-cancer effects. Nevertheless, little is known about the anti-inflammatory effects of IAL, and the role of IAL in sepsis is unclear. In this study, we demonstrated that IAL decreased lipopolysaccharide (LPS)-mediated production of nitric oxide, PEG2 and cytokines (IL-6, TNF-α) in peritoneal macrophages and RAW 264...
