The adaptor protein alpha-syntrophin (SNTA) is differentially expressed in varying types of cancer and affects triglyceride levels, inflammatory response and cell proliferation. However, little is known about the expression of SNTA in liver diseases. Non-alcoholic steatohepatitis (NASH) is characterized by hepatic steatosis, inflammation and eventually fibrosis, and may progress to hepatocellular carcinoma (HCC). Here, SNTA mRNA was analyzed in liver tissues from 71 non-alcoholic fatty liver disease patients and 32 controls to assess associations with disease characteristics...

Low-density lipoprotein nanoparticles reconstituted with the natural omega-3 fatty acid, docosahexaenoic acid (LDL-DHA), have been reported to selectively kill hepatoma cells and reduce the growth of orthotopic liver tumors in the rat. To date, little is known about the cell death pathways by which LDL-DHA nanoparticles kill tumor cells. Here we show that the LDL-DHA nanoparticles are cytotoxic to both rat hepatoma and human hepatocellular carcinoma (HCC) cell lines. Following LDL-DHA treatment both rat and human HCC cells experience pronounced lipid peroxidation, depletion of glutathione and inactivation of the lipid antioxidant glutathione peroxidase-4 (GPX4) prior to cell death...

Purpose: We have developed a systemic hepatic-damage index (SHI) based on serum total cholesterol (TC) and high density lipoprotein levels (HDL) and determined its prognostic significance in hepatocellular carcinoma (HCC) patients undergoing resection. Experimental Design: The SHI was analyzed in the training cohort of 188 HCC patients and in the validation cohort of 177 HCC patients. The systemic immune-inflammation index (SII) scores in the validation cohorts were also measured. Area under the receiver operating characteristic curve (AUC) was used to explore the prediction accuracy in HCC patients...

Agrin is utilized by motor neurons to stimulate the LRP4-MuSK receptor in muscles for neuromuscular junction (NMJ) formation. Recent studies of cancer have identified novel functions of the low-density lipoprotein receptor-related protein 4-muscle-specific kinase (LRP4-MuSK) pathway. Agrin may act as a mechanotransduction signal in the extracellular matrix (ECM) to coordinate the cross-talk between the LRP4-MuSK pathway and integrin-focal adhesion pathway. Ensuing Yes-associated protein (YAP) activation promotes hepatocellular carcinoma (HCC)...

Hepatocellular carcinoma (HCC) treatment remains lack of effective chemopreventive agents, therefore it is very attractive and urgent to discover novel anti-HCC drugs. In the present study, the effects of chlorogenic acid (ChA) and caffeic acid (CaA) on HCC induced by diethylnitrosamine (DEN) were evaluated. ChA or CaA could reduce the histopathological changes and liver injury markers, such as alanine transarninase, aspartate aminotransferase, alkaline phosphatase, total bile acid, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol...

BACKGROUND: Hepatocellular carcinoma (HCC) most commonly occurs in the setting of liver cirrhosis which is characterized by low serum lipids. We hypothesized that composition of lipoproteins and consequently lipid species ratios are mostly unchanged in patients with cirrhosis compared to controls. This approach may be appropriate to identify lipid ratios altered in HCC irrespective of liver dysfunction. PATIENTS AND METHODS: Lipids were measured in serum of 21 patients with HCC, 41 patients with liver cirrhosis and 22 controls...

BACKGROUND/AIMS: Previous studies have observed disturbances in the (1)H nuclear magnetic resonance (NMR) blood spectral profiles in malignancy. No study has metabotyped serum or plasma of hepatocellular carcinoma (HCC) patients from two diverse populations. We aimed to delineate the HCC patient metabotype from Nigeria (mostly hepatitis B virus infected) and Egypt (mostly hepatitis C virus infected) to explore lipid and energy metabolite alterations that may be independent of disease aetiology, diet and environment...

BACKGROUND: Hepatocellular carcinoma has high incidence and mortality worldwide. Liver is the site of most metabolic biotransformation, which could reflect the status of cells. Most plasma apolipoproteins, endogenous lipids and lipoproteins are synthesized in the liver. Therefore, the effects of lipid metabolites on prognosis of HCC deserved to be explored. METHODS: We prospectively included 58 healthy donors (HD), 50 chronic hepatitis (CH) patients and a training cohort of 189 patients with HCC who underwent curative resections at Zhongshan Hospital from January 2012 to August 2012...

Nonalcoholic fatty liver disease (NAFLD) spans steatosis through nonalcoholic steatohepatis, cirrhosis, and hepatocellular carcinoma (HCC) associated with striking systemic features and excess cardiovascular and liver-related mortality. The pathogenesis of NAFLD is complex and multifactorial. Endocrine derangements are closely linked with dysmetabolic traits. For example, in animal and human studies, female sex is protected from dysmetabolism thanks to young individuals' ability to partition fatty acids towards ketone body production rather than very low density lipoprotein (VLDL)-triacylglycerol, and to sex-specific browning of white adipose tissue...

Present study, was an effort to scrutinize the molecular and biochemical role of ibuprofen and thiamine combination in diethylnitrosamine (DEN)-induced HCC in Wistar rats. Single intraperitoneal injection of DEN (200 mg/kg) was used for induction of HCC in rats. The rats were divided into eight various groups. DEN induced rats were treated with pure ibuprofen (40 mg/kg) and thiamine in combination for the period of 12th weeks. The protocol was terminated after the 16th week. Exposure of DEN up-regulated the levels of different serum biochemical parameters, antioxidant enzyme level, Alfa-fetoprotein (AFP) and reduced the level of High density lipoprotein (HDL) in Wistar rats along with the alteration in pro-inflammatory cytokines viz...

Actinidia chinensis Planch root extract (acRoots) is a traditional Chinese medicine with anti-tumor efficacy. To investigate the mechanisms responsible for this activity, we examined the effects of acRoots on cholesterol metabolism in hepatocellular carcinoma (HCC). mRNA chip analysis was used to identify the metabolic genes regulated by acRoots. The effects of acRoots on cholesterol synthesis and uptake were evaluated by measuring intracellular cholesterol levels and 3,3'-dioctadecylindocarbocyanine-labeled low-density lipoprotein (Dil-LDL) uptake...

BACKGROUND: The mechanism for hypercoagulability in malignancy is not entirely understood. Although several studies report contrasting finding about the link between elevated plasma levels of the lipoprotein(a) [Lp(a)] and the possible recurrence of venous thromboembolism, we perform a study to evaluate the impact of the Lp(a) in the development of portal vein thromboembolism (PVT) in patients with HCC. METHODS: We compared 44 PVT patients with 50 healthy subjects and 50 HCC patients...

As a major protein constituent of high density lipoprotein, Apolipoprotein A1 (ApoA-1) might be associated with cancer progression. Our study investigated the serum ApoA-1 level for the prognosis of 443 patients with hepatocellular carcinoma (HCC) and its effects on tumor cells. We found that the serum ApoA-1 level was significantly lower in HCC patients with tumor recurrence, and was an independent indicator of tumor-free survival and overall survival. Low serum ApoA-1 levels were significantly associated with multiple tumors and high Barcelona Clinic Liver Cancer stage...

BACKGROUND & AIMS: Although it is well established that fatty acids (FA) are indispensable for the proliferation and survival of cancer cells in hepatocellular carcinoma (HCC), inhibition of Fatty Acid Synthase (FASN) cannot completely repress HCC cell growth in culture. Thus, we hypothesized that uptake of exogenous FA by cancer cells might play an important role in the development and progression of HCC. Lipoprotein lipase (LPL) is the enzyme that catalyses the hydrolysis of triglycerides into free fatty acids (FFA) and increases the cellular uptake of FA...

BACKGROUND: Hepatitis B virus (HBV) infection correlated with the development of cirrhosis, liver failure and hepatocellular carcinoma (HCC), poses a huge health burden on the global community. However, the pathogenesis of chronic hepatitis B (CHB) remains unclear. Apolipoprotein A1 (ApoA1) mainly secreted by hepatocytes, represents the major protein component of high-density lipoprotein. ApoA1 secretion may be disrupted by HBV infection. In this study, we mainly investigated the molecular mechanism of ApoA1 down regulated by HBV for revealing the pathogenesis of CHB...
