Apolipoprotein O (ApoO) was recently observed in the cellular mitochondrial inner membrane, which plays a role in mitochondrial function and is associated with myocardiopathy. Empirical information on the physiological functions of apoO is therefore limited. In this study, we aimed to elucidate the effect of apoO on hepatic fatty acid metabolism. An adenoviral vector expressing hApoO was constructed and introduced into chow diet and high-fat diet induced mice and the L02 human hepatoma cell line. High levels of hApoO mRNA and protein were detected in the liver, and the expression of lipid metabolism genes was significantly altered compared with negative controls...

Ischemia-reperfusion injury (IRI), induced by abnormal mitochondrial fission related apoptosis, is a major concern in liver transplantation settings. Our previous studies have demonstrated that hepatic stimulator substance (HSS) is an anti-apoptotic effector and could protect liver from IRI. However, the underlying mechanism remains unclear. In the present study, we report that in vitro and in vivo HSS could regulate mitochondrial fission and hepatocyte apoptosis during liver IRI by orchestrating the translocation and activation of dynamin-related protein 1 (Drp1)...

Alcoholic liver diseases and virus-induced hepatic dysfunctions are prevalent in western countries. Evidence also suggests that hyperglycemia and insulin resistance are key players in the development of hepatic diseases and their complications. Since the comorbid diseases like obesity, diabetes and vascular dysfunctions primarily affect liver, the modern therapies against other hepatic dysfunctions are becoming a major challenge to treat. In addition to these, polypharmacy and adverse drug reactions (ADRs) are further aggravating the phenomenon...

AIMS: Non-alcoholic steatohepatitis (NASH) is characterized by steatosis, panlobular inflammation, liver fibrosis and increased cardiovascular mortality. Dipeptidyl peptidase-4 (DPP-4) inhibitors (gliptins) are indirect glucagon like peptide 1 (GLP-1) agonists with antidiabetic and anti-inflammatory activity, used for the treatment of type 2 diabetes. Their potential and underlying mechanisms to treat metabolic liver inflammation and fibrosis as well as the associated vascular dysfunction remain to be explored...

To identify an agent with specific activity against B-lineage leukemia stem cells (B-LSCs), we generated norcantharidin (NCTD)-encapsulated liposomes modified with a novel humanized anti-human CD19 monoclonal antibody, Hm2E8b (Hm2E8b-NCTD-liposomes). These liposomes were specially designed to recognize and kill B-LSCs in vitro, and to decrease non-specific cytotoxicity to untargeted cells. Hm2E8b-NCTD-liposomes selectively ablated B-LSCs through targeting hepatic leukemia factor (HLF), which is implicated in hematopoietic stem cell regulation and is overexpressed in LSCs...

BACKGROUND: Cystathionine-γ-lyase (CSE) was shown to have a regulatory role in glucose metabolism. Circulatory shock can induce metabolic stress, thereby leading to hyperglycemia and mitochondrial dysfunction. In vitro data suggest an effect of high glucose on CSE expression. Therefore, the aim of this study was to investigate the effects of hyperglycemia on CSE expression in resuscitated murine septic shock. METHODS: Normo- (80-150 mg/dl) and hyperglycemic (>200 mg/dl) male C57/BL6J mice (n = 5-6 per group) underwent cecal ligation and puncture (CLP)-induced polymicrobial sepsis or sham procedure (n = 6 per group) and, 15 h afterwards, were anesthetized again, surgically instrumented and received intensive care treatment, including antibiotics, lung protective mechanical ventilation, circulatory support, and intravenous (i...

The incidence of non-alcoholic fatty liver disease (NAFLD) increases with age. Cellular senescence refers to a state of irreversible cell-cycle arrest combined with the secretion of proinflammatory cytokines and mitochondrial dysfunction. Senescent cells contribute to age-related tissue degeneration. Here we show that the accumulation of senescent cells promotes hepatic fat accumulation and steatosis. We report a close correlation between hepatic fat accumulation and markers of hepatocyte senescence. The elimination of senescent cells by suicide gene-meditated ablation of p16(Ink4a)-expressing senescent cells in INK-ATTAC mice or by treatment with a combination of the senolytic drugs dasatinib and quercetin (D+Q) reduces overall hepatic steatosis...

Soy protein is effective at preventing hepatic steatosis; however, the mechanisms are poorly understood. We tested the hypothesis that soy vs. dairy protein-based diet would alter microbiota and attenuate hepatic steatosis in hyperphagic Otsuka Long-Evans Tokushima fatty (OLETF) rats. Male OLETF rats were randomized to "Western" diets containing milk protein isolate (MPI), soy protein isolate (SPI) or 50:50 MPI/SPI (MS) (n=9-10/group; 21% kcal protein) for 16 weeks. SPI attenuated (P<.05) fat mass and percent fat by ~10% compared with MS, but not compared with MPI...

Mitochondrial dysfunction is associated with several clinical manifestations including diabetes, neurological disorders, renal and hepatic diseases and myopathy. While mitochondrial dysfunction is associated with increased bone resorption and decreased bone formation in mouse models, effects of alterations in mitochondrial function on bone remodelling and mass have not been investigated in humans. We recruited 45 carriers (29 females, 16 males) with the m.3243A > G mutation and healthy controls matched for gender, age, height and menopausal status...

BACKGROUND: Liver inflammation or hepatitis is a result of pluripotent interactions of cell death molecules, cytokines, chemokines and the resident immune cells collectively called as microenvironment. The interplay of these inflammatory mediators and switching of immune responses during hepatotoxic, viral, drug-induced and immune cell-mediated hepatitis decide the fate of liver pathology. The present review aimed to describe the mechanisms of liver injury, its relevance to human liver pathology and insights for the future therapeutic interventions...

Rosiglitazone and pioglitazone are thiazolidinedione (TZD) compounds that have been used clinically as insulin-sensitizing drugs and are generally believed to mediate their effects via activation of the peroxisome proliferator-activated receptor γ (PPARγ). Recent work has shown that it is possible to synthesize TZD compounds with potent insulin-sensitizing effects and markedly-diminished affinity for PPARγ. Both clinically-used TZDs and investigational PPARγ-sparing TZDs, such as MSDC-0602, interact with the mitochondrial pyruvate carrier (MPC) and inhibit its activity...

INTRODUCTION: Organ-specific autoimmune diseases are believed to result from immune responses generated against self-antigens specific to each organ. However, when such responses target antigens expressed promiscuously in multiple tissues, then the immune-mediated damage may be wide spread. METHODS: In this report, we describe a mitochondrial protein, branched chain α-ketoacid dehydrogenase kinase (BCKDk ) that can act as a target autoantigen in the development of autoimmune inflammatory reactions in both heart and liver...

Pan-genotypic nucleoside HCV inhibitors display a high genetic barrier to drug resistance and are the preferred direct acting agents to achieve complete sustained virologic response in humans. Herein, we report, the discovery of a -D-2'-Cl,2'-F-uridine phosphoramidate nucleotide 16, as a non-toxic pan-genotypic anti-HCV agent. Phosphoramidate 16 in its 5'-triphosphate form specifically inhibited HCV NS5B polymerase with no marked inhibition of human polymerases and cellular mitochondrial RNA polymerase. Studies on the intracellular half-life of phosphoramidate 16-TP in live cells demonstrated favorable half-life of 11...

Due to the epidemic of obesity across the world, nonalcoholic fatty liver disease (NAFLD) has become one of the most prevalent chronic liver disorders in children and adolescents. NAFLD comprises a spectrum of fat-associated liver conditions that can result in end-stage liver disease and the need for liver transplantation. Simple steatosis, or fatty liver, occurs early in NAFLD and may progress to nonalcoholic steatohepatitis, fibrosis and cirrhosis with increased risk of hepatocellular carcinoma. The mechanism of the liver injury in NAFLD is currently thought to be a "multiple-hit process" where the first "hit" is an increase in liver fat, followed by multiple additional factors that trigger the inflammatory activity...

Nuclear receptors Farnesoid X Receptor (FXR) and Small Heterodimer Partner (SHP) are important regulators of bile acid, lipid and glucose homeostasis. Here we show that global Fxr (-/-) Shp(-/-) double knockout (DKO) mice are refractory to weight gain, glucose intolerance and hepatic steatosis when challenged with high-fat diet. DKO mice display an inherently increased capacity to burn fat and suppress de novo hepatic lipid synthesis. Moreover, DKO mice are also very active and that correlates well with the observed increase in Pepck expression, type IA fibers and mitochondrial function in the skeletal muscle...

Non-alcoholic fatty liver disease (NAFLD) is in parallel with the obesity epidemic and it is the most common cause of liver diseases. The development of hepatic steatosis in majority of patients is linked to dietary fat ingestion. NAFLD is characterized by excess accumulation of triglyceride in the hepatocyte due to both increased inflow of free fatty acids and de novo hepatic lipogenesis. Insulin resistance with the deficiency of insulin receptor substrate-2 (IRS-2)-associated phosphatidylinositol 3-kinase (PI3K) activity causes an increase in intracellular fatty acid-derived metabolites such as diacylglycerol, fatty acyl CoA or ceramides...

Mono(2-ethylhexyl) phthalate (MEHP), the active metabolite of di(2-ethylhexyl) phthalate (DEHP), has been known to have adverse effects on the reproductive system, urologic systems, hepatic, developmental toxicities and carcinogenicity. However, the effect of MEHP on cardiovascular toxicity remains unclear. Therefore, we aimed to evaluate the cytotoxic effects of MEHP and the possible molecular mechanism. We found that treatment of EA.hy 926 cells with MEHP induced autophagy at earlier time (6 h) in this study...

Nonalcoholic fatty liver disease (NAFLD), the hepatic manifestation of the metabolic syndrome, has emerged as one of the most common causes of chronic liver disease in developed countries over the last decade. NAFLD comprises a spectrum of pathological hepatic changes, including steatosis, steatohepatitis, advanced fibrosis, and cirrhosis. Autophagy, a homeostatic process for protein and organelle turnover, is decreased in the liver during the development of NAFLD. Previously, we have shown that carbon monoxide (CO), a reaction product of heme oxygenase (HO) activity, can confer protection in NAFLD, though the molecular mechanisms remain unclear...
