Proteomic analysis of fatty liver induced by starvation of medaka fish larvae

ABSTRACT: When medaka fish larvae are grown in the absence of exogenous nutrition, the liver becomes dark and positive to Oil Red O staining. We examined the the mechanism of this starvation-induced development of fatty liver by proteomic analysis using livers obtained from larvae grown in the presence or absence of 2% glucose at 5 days-post-hatch.

Effect of Concentration and type of Dietary Fatty Acid on Development of Nonalcoholic Fatty Liver Disease

Project description:The current study was designed to determine if dietary fatty acid concentration and composition affects the development and progression of nonalcoholic fatty liver disease. Male SD rats were overfed diets low (5%) or high (70%) fat diets via total enteral nutrition where the fat source was olive oil (monounsaturated), or corn oil (polyunsaturated). Overfeeding 5% corn oil produced little steatosis relative to feeding 5% olive oil. This was associated with lower fatty acid synthesis and reduced SREBP-c signaling in the 5% corn oil group. Overfeeding 70% fat diets increased steatosis and lead to increased liver necrosis in the 70% corn oil but not olive oil group. Increased injury after feeding polyunsaturated fat diets was linked to peroxidizability of hepatic free fatty acids and triglycerides and appearance of peroxidaized lipid products HETES and HODES previously linked to clinical nonalcoholic steatohepatitis.

Activating transcription factor 6 is necessary and sufficient for alcoholic fatty liver disease in zebrafish

Project description:ATF6 is a key regulator of the unfolded protein response. Through use of zebrafish and cultured cells we demonstrate that ATF6 drives fatty liver disease by interaction with fatty acid synthase (FASN). Total small RNA from livers of 5 dpf larval zebrafish were collected: 2 batches of Tg(fabp10:nls-mCherry) control larvae, 2 batches of ethanol-treated Tg(fabp10:nls-mCherry) larvae, and 1 batch of Tg(fabp10:nAtf6-cherry; cmlc2:GFP). Each batch was purified for preparation of high-throughput sequencing libraries.

Protection from starvation-induced liver atrophy.

Project description:Starvation causes the accumulation of lipid droplets in the liver, a somewhat counterintuitive phenomenon that is nevertheless conserved from flies to humans. Much like fatty liver resulting from overfeeding, hepatic lipid accumulation (steatosis) during undernourishment can lead to lipotoxicity and atrophy of the liver. Here, we found that while surface populations of Astyanax mexicanus undergo this evolutionarily conserved response to starvation, the starvation-resistant cavefish larvae of the same species do not display an accumulation of lipid droplets upon starvation. Moreover, cavefish are resistant to liver atrophy during starvation, providing a unique system to explore strategies for liver protection. Using comparative transcriptomics between zebrafish, surface fish, and cavefish, we identified the fatty acid transporter slc27a2a/fatp2 to be correlated with the development of fatty liver. Pharmacological inhibition of slc27a2a in zebrafish rescues steatosis and atrophy of the liver upon starvation. Further, down-regulation of FATP2 in drosophila larvae inhibits the development of starvation-induced steatosis, suggesting the evolutionary conserved importance of the gene in regulating fatty liver upon nutrition deprivation. Overall, our study identifies a conserved, druggable target to protect the liver from atrophy during starvation.

Transcriptome analysis of garlic induced hepatoprotection against alcoholic fatty liver

Project description:Alcohol induced fatty liver cause a dangerous health problem and is the major cause of morbidity and mortality worldwide. Garlic (Allium sativum) is documented to possess anti-fatty liver properties. However the exact molecular mechanisms are unknown. The main aim of this experiment is to elucidate the underlying pathways through which garlic ameliorates alcohol induced fatty liver. Dially disulfide and garlic oil were the garlic compounds used in this study. Leiber DeCarli ethanol liquid diet was to induce fatty liver in C57BL/6 mice model. Also the expression impaired by alcohol induced fatty liver is another aim of this study. Leiber-Decarli ethanol diet was used to induce fatty liver in male C57BL/6 mice (n=12). For control, Lieber-DeCarli liquid control diet was fed to mice (n=4). The control mice were pair-fed to the ethanol mice. After adaptation, the ethanol fed mice were divided into three groups viz. alcohol (n=4), dially disulfide [DADS] (n=4) and garlic oil [GO] (n=4). The study started with the administration of DADS (15 mg/kg bw) or GO (50 mg/kg bw) mixed in 0.1 ml olive oil through gavage. For the control and alcohol groups, same amount of olive oil (0.1 ml) was gavaged. The mice were gavaged daily for 4 weeks. The mice were euthanized by CO2 and blood was collected by cardiac puncture. Liver, kidney, spleen, lungs and hearts were collected and their weights recorded. A portion of liver was snap frozen in liquid nitrogen (200 mg) for RNA extraction.

Expression data that were specifically regulated by lncRNA-LFAR1 in livers of mice undergoing hepatic fibrosis.

Project description:Long noncoding RNAs (lncRNAs) play important roles in various biological processes; however, few have been identified that regulate hepatic stellate cells (HSCs) activation and the progression of liver fibrosis. Through a detailed analysis of the expression of lncRNAs in various tissues, we discovered the existence of a liver enriched lncRNA-LFAR1 (lncRNA-Liver Fibrosis Associated RNA1). To identify the roles of lncRNA-LFAR1 in liver fiboris, we systematically analyzed the regulation of mRNAs in the livers of mice treated with oil in combination with injection of Lenti-NC (NC, n=3), CCl4 in combination with injection of Lenti-NC (NC+CCl4, n=3), oil in combination with injection of Lenti-shLFAR1 (shLFAR1, n=3) and CCl4 in combination with injection of Lenti-shLFAR1 (shLFAR1+CCl4, n=3) by mRNA microarrays, which revealed a panel of mRNAs that were specifically regulated by lncRNA-LFAR1 in livers of mice undergoing hepatic fibrosis. To identify the roles of lncRNAs-LFAR1 in regulating liver fiboris and the potential targets of lncRNA-LFAR1 in liver fiboris,we determined the mRNA expression profiles in the livers of Balb/c mice treated with oil in combination with injection of Lenti-NC (NC, n=3), CCl4 in combination with injection of Lenti-NC (NC+CCl4, n=3), oil in combination with injection of Lenti-shLFAR1 (shLFAR1, n=3) and CCl4 in combination with injection of Lenti-shLFAR1 (shLFAR1+CCl4, n=3) by mRNA microarrays.

Genomics of Hepatocellular Carcinoma

Project description:<p>Despite the growing incidence of hepatocellular carcinoma (HCC) due to increased hepatitis C virus infection and non-alcoholic steatohepatitis in Western populations, the genetic determinants of this cancer have yet to be established. A minority (15-20%) of HCC occurs in livers without cirrhosis or other chronic disease. Because the liver is functionally preserved in these patients and surgical resection of the tumor may be performed safely, and because of the scarcity of livers available for transplantation, non-cirrhotic patients undergo surgical resection for HCC treatment. These resected tumors present investigatory opportunities in two ways: First, they provide tumor specimen which have not been treated with chemotherapy and embolization. Second, the absence of cirrhosis may provide an unconfounded background from which to investigate the genetic tumorigenesis of HCC. In livers with cirrhosis, genetic instability is prevalent as assessed by assays for microsatellite instability, loss of heterozygosity and aberrant DNA methylation. In contrast, in livers without cirrhosis, the non-tumor tissue surrounding HCC have been found to have fewer genetic aberrations. It has been postulated that the pathologic process of cirrhosis may result in the accumulation of many "passenger"; as well as "driver" mutations, and that the examination of the HCC cancer genome may be facilitated in non-cirrhotic livers because of the absence of an accumulated background noise of mutations.</p>
