BACKGROUND: Studies have demonstrated that resveratrol (a natural polyphenol) and caloric restriction activate Sirtuin-1 (SIRT1) and induce autophagy. Furthermore, autophagy is induced by the SIRT1-FoxO signaling pathway and was recently shown to be a critical protective mechanism against non-alcoholic fatty liver disease (NAFLD) development. We aimed to compare the effects of resveratrol and caloric restriction on hepatic lipid metabolism and elucidate the mechanism by which resveratrol supplementation and caloric restriction alleviate hepatosteatosis by examining the molecular interplay between SIRT1 and autophagy...

INTRODUCTION: Little is known about hepatotoxicity in patients with schistosome and HIV co-infections. Several studies have reported increased liver enzymes and bilirubin levels associated with schistosome infection. We investigated whether HIV-infected adults on antiretroviral therapy who had S. mansoni co-infection had a higher prevalence of hepatotoxicity than those without. METHODOLOGY/PRINCIPAL FINDINGS: We determined the presence and grade of hepatotoxicity among 305 HIV-infected outpatients who had been on medium-term (3-6 months) and long-term (>36 months) antiretroviral therapy in a region of northwest Tanzania where S...

AIMS: In patients with type 1 diabetes, basal insulin peglispro (BIL) lowers weight and increases plasma triglycerides (TG) and hepatic fat relative to insulin glargine (GL). To explain this, we hypothesised that BIL's attenuated peripheral effects may include increased free fatty acid flux to the liver, causing increased VLDL-TG secretion and lipid oxidation, and decreased TG adipose tissue deposition. MATERIALS AND METHODS: In this open-label, randomised, 2-period crossover study, 14 patients with type 1 diabetes received once-daily, individualised, stable BIL or GL doses for 3 weeks...

Kallikrein 14 (KLK14) is a serine protease linked to several pathologies including prostate cancer and positively correlates with Gleason score. Though KLK14 functioning in cancer is poorly understood, it has been implicated in HGF/Met signaling, given that KLK14 proteolytically inhibits HGF activator-inhibitor 1 (HAI-1), which strongly inhibits pro-HGF activators, thereby contributing to tumor progression. In this work, KLK14 binding to either hepatocyte growth factor activator inhibitor type-1 (HAI-1) or type-2 (HAI-2) was essayed using homology modeling, molecular dynamic simulations and free-energy calculations through MM/PBSA and MM/GBSA...

Metastasis is the major cause of the poor prognosis of hepatocellular carcinoma (HCC), and increasing evidence supports the contribution of miRNAs to cancer progression. However, the exact relationship between the level of miR-1301 expression and HCC cell migration, invasion, and angiogenesis remains largely unknown. Quantitative PCR was used to evaluate the level of miR-1301 expression in HCC tissues and cell lines. Transwell and tube-formation assays were used to measure the effects of miR-1301 on HCC cell migration and invasion, and angiogenesis, respectively...

Platelet, neutrophil, and lymphocyte ratio (PNLR) has its own unique role in influencing postoperative recurrence for patients with hepatocellular carcinoma (HCC). Surgical stress can change systemic inflammatory response of patients. Thus the aim of this study was to identify the prognostic value of changes of platelet times neutrophil to lymphocyte ratio in hepatitis B related HCC within Barcelona clinical liver cancer (BCLC) stage A.Data of patients with HCC within BCLC stage A were reviewed. Pre-, intra- and postoperative variables were retrospectively and statistically analyzed...

Recently, it has been suggested that peritumoral decreased uptake area (PDUA) in the hepatobiliary phase (HBP) of gadoxetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) was associated with vascular invasion in hepatocellular carcinoma (HCC). We aimed to investigate correlations between microvascular invasion and PDUA, and elucidate the predictability of PDUA for tumor recurrence after resection.We retrospectively analyzed clinicopathological and radiological data from 126 consecutive patients with single HCC ≤5 cm without macrovascular invasion who underwent preoperative Gd-EOB-DTPA-enhanced MRI and surgical resection...

Metformin is widely used in the treatment of type 2 diabetes to lower blood glucose. Although metformin is a relatively safe and effective drug, its clinical efficacy is variable and under certain circumstances it may contribute to life-threatening lactic acidosis. Thus, additional understanding of metformin pharmacokinetics and pharmacodynamics could provide important information regarding therapeutic use of this widely prescribed drug. Here we report a significant effect of time of day on acute blood glucose reduction in response to metformin administration and on blood lactate levels in healthy mice...

This study investigated the effects of Akebia quinata (AQ) leaf and fruit extract on acute alcohol-induced hepatotoxicity in AML12 cells. Different concentrations of AQ extracts (250 and 2500 μg/mL) were used to treat the AML12 cells with or without ethanol for 24 h for inducing acute alcohol cytotoxicity. AQ extract-treated AML12 cells showed enhanced expression of GSH-synthesizing enzymes and suppressed expression of oxidative stress makers such as NOX4, and decreased expression of tumor necrosis factor-α, inflammatory marker, in acute alcohol-induced hepatotoxicity...

Research findings that suggest beneficial health effects of dietary supplementation with virgin coconut oil (VCO) are limited in the published literature. This study investigated the in vivo effects of a 5-week VCO-supplemented diet on lipid profile, hepatic antioxidant status, hepatorenal function, and cardiovascular risk indices in normal rats. Rats were randomly divided into 3 groups: 1 control and 2 treatment groups (10% and 15% VCO-supplemented diets) for 5 weeks. Serum and homogenate samples were used to analyze lipid profile, hepatorenal function markers, hepatic activities of antioxidant enzymes, and malondialdehyde level...

Potent mechanism-based inactivators can be rationally designed against PLP-dependent drug targets, such as ornithine aminotransferase (OAT) or γ-aminobutyric acid aminotransferase (GABA-AT). An important challenge, however, is the lack of selectivity towards other PLP-dependent off-target enzymes, because of similarities in mechanisms of all PLP-dependent aminotransferase reactions. On the basis of complex crystal structures, we investigate the inactivation mechanism of OAT, a hepatocellular carcinoma (HCC) target, by (1R,3S,4S)-3-amino-4-fluorocyclopentane-1-carboxylic acid (FCP), a known inactivator of GABA-AT...

A hepatitis B virus (HBV) transgenic mice model was used to establish the fatty liver superimposed model by feeding the methionine choline-deficient (MCD) diet for 8 weeks, with or without the gavage of 2 mg/kg zeaxanthin dipalmitate (ZD) three times per week. Both wild-type and HBV transgenic mice, with MCD diet, gained typical non-obese non-alcoholic steatohepatitis (NASH) and HBV symptoms. Coadministration with ZD exhibited evident therapeutic effects through alleviating those pathological events. Moreover, long-term vehicle-ZD treatment was found to be safe...

WWC family proteins negatively regulate HEK293 cell proliferation and organ growth by suppressing the transcriptional activity of Yes-associated protein (YAP), a major effector of the Hippo pathway. The function of the scaffolding protein WWC1 (also called KIBRA) has been intensively studied in cells and animal models. However, the expression and clinicopathologic significance of WWC2 in cancer are poorly characterized. This study aimed to clarify the biological function and mechanism of action of WWC2 in hepatocellular carcinoma (HCC)...

There are gender-specific variations in the epidemiology and clinical course of hepatitis C virus (HCV) infection. However, few long-term longitudinal studies have examined trends in the incidence and prevalence of serious liver complications among women compared with men with HCV infection. We used the Veterans Administration Corporate Data Warehouse to identify all veterans with positive HCV viraemia from January 2000 to December 2013. We calculated gender-specific annual incidence and prevalence rates of cirrhosis, decompensated cirrhosis and hepatocellular cancer (HCC) adjusting for age, diabetes, HIV and alcohol use...

Abnormal gametogenesis and embryonic development may lead to poor health status of the offspring. The operations involved in the assisted reproductive technologies (ARTs) occur during the key stage of gametogenesis and early embryonic development. To assess the potential risk of abnormal lipid metabolism in the liver of adult ARTs offspring, two ARTs mice models derived from preimplantation genetic diagnosis (PGD group) and in vitro cultured embryos without biopsy (IVEM group) were constructed. And control mice were from in vivo naturally conceived (Normal group)...
