Aldose reductase (AR) expression is increased in liver tissue of patients with ethanol‑induced liver disease. However, the exact role of AR in the development of ethanol‑induced liver disease has yet to be elucidated. The present study aimed to determine the effect of an AR inhibitor on ethanol‑induced steatosis in HepG2 cells and to identify possible underlying molecular mechanisms. Steatosis was induced in HepG2 cells by stimulating cells with 100 mM absolute ethanol for 48 h. Oil Red O staining was used to detect the lipid droplet accumulation in cells...

A high‑fat diet or high‑cholesterol diet (HCD) is a major cause of metabolic diseases, including obesity and diabetes; vascular diseases, including hypertension, stroke and arteriosclerosis; and liver diseases, including hepatic steatosis and cirrhosis. The present study aimed to evaluate the effects of deep sea water (DSW) on rats fed a HCD. DSW decreased HCD‑induced increases in total cholesterol and low‑density lipoprotein (LDL) cholesterol in the blood, and recovered high‑density lipoprotein cholesterol...

Gene-associated with retinoid-interferon-induced mortality 19 (GRIM-19) targets multiple signaling pathways involved in cell death and growth. However, the role of GRIM-19 in the pathogenesis of hepatitis virus infections remains unexplored. Here, we investigated the restrictive effects of GRIM-19 on the replication of hepatitis C virus (HCV). We found that GRIM-19 protein levels were reduced in HCV-infected Huh7 cells and Huh7 cells harboring HCV replicons. Moreover, ectopically expressed GRIM-19 caused a reduction in both intracellular viral RNA levels and secreted viruses in HCVcc-infected cell cultures...

Nuclear receptor coactivator 6 (NCOA6) is a transcriptional coactivator and crucial for insulin secretion and glucose metabolism in pancreatic β-cells. However, the regulatory mechanism of β-cell function by NCOA6 is largely unknown. In this study, we found that the transcript levels of nicotinamide phosphoribosyltransferase (Nampt) were decreased in islets of NCOA6(+/-) mice compared with NCOA6(+/+) mice. Moreover, NCOA6 overexpression increased the levels of Nampt transcripts in the mouse pancreatic β-cell line NIT-1...

Non-alcoholic fatty liver disease (NAFLD) is caused by fat accumulation and is associated with abnormal cholesterol metabolism. Previous work indicates that polysaccharides from alga Enteromorpha prolifera improve glucose metabolism and lower cholesterol in diabetic rats. Thus, we studied the possible protective effects of E. prolifera polysaccharides (EP) in the development of NAFLD and underlying mechanisms. EP (200 mg kg(-1)) significantly reduced the liver weight and significantly lowered hepatic HMG-CoA reductase (HMGCR) mRNA protein expression...

Sterol regulatory element binding proteins (SREBPs) are conserved from yeast to mammalian cells and function in the regulation of sterol homeostasis. In fungi, the SREBP pathway has been implicated in the adaptation to hypoxia and in virulence. In Neurospora crassa and Trichoderma reesei, the SREBP pathway also negatively regulates protein secretion under lignocellulolytic conditions. Here we utilized global transcriptional profiling combined with genetic and physiological analyses to address the regulatory link between the SREBP pathway and protein secretion in N...

There is controversial information about the adverse effect of sucrose (S) or fructose (F) in the development of obesity. Thus, the purpose of the study was to evaluate the effect of S or F in a high fat diet (HF) on gut microbiota and renal oxidative stress. Rats were fed for four months with either high-fat + sucrose (HFS) or high-fat + fructose (HFF) or a control diet (C). Half of the HFS or HFF groups were maintained with the same diet and the other half were switched to the consumption of C. HFS and HFF groups increased 51% and 19% body weight, respectively, compared with the C group...

Cells employ regulated transport mechanisms to ensure that their plasma membranes (PMs) are optimally supplied with cholesterol derived from uptake of low-density lipoproteins (LDL) and synthesis. To date, all inhibitors of cholesterol transport block steps in lysosomes, limiting our understanding of post-lysosomal transport steps. Here, we establish the cholesterol-binding domain 4 of anthrolysin O (ALOD4) as a reversible inhibitor of cholesterol transport from PM to endoplasmic reticulum (ER). Using ALOD4, we: 1) deplete ER cholesterol without altering PM or overall cellular cholesterol levels; 2) demonstrate that LDL-derived cholesterol travels from lysosomes first to PM to meet cholesterol needs, and subsequently from PM to regulatory domains of ER to suppress activation of SREBPs, halting cholesterol uptake and synthesis; and 3) determine that continuous PM-to-ER cholesterol transport allows ER to constantly monitor PM cholesterol levels, and respond rapidly to small declines in cellular cholesterol by activating SREBPs, increasing cholesterol uptake and synthesis...

The therapeutic use of statins has been associated to a reduced risk of Parkinson's disease (PD) and may hold neuroprotective potential by counteracting the degeneration of dopaminergic neurons. Transcriptional activation of the sterol regulatory element-binding protein (SREBP) is one of the major downstream signalling pathways triggered by the cholesterol-lowering effect of statins. In a previous study in neuroblastoma cells, we have shown that statins consistently induce the up-regulation of presynaptic dopaminergic proteins as well as changes of their function and these effects were accompanied by downstream activation of SREBP...

Sterol regulatory element binding protein 1 (SREBP-1) is well-known as the master regulator of lipogenesis in rodents. Acyl-CoA synthetase short-chain family member 2 (ACSS2) plays a key role in lipogenesis by synthesizing acetyl-CoA from acetate for lipogenesis. ATP citrate lyase (ACLY) catalyzes the conversion of citrate and coenzyme A to acetyl-CoA, hence, it is also important for lipogenesis. Although ACSS2 function in cancer cells has been elucidated, its essentiality in ruminant mammary lipogenesis is unknown...

BACKGROUND: Eicosapentaenoic acid (EPA, C20:5n-3), docosahexaenoic acid (DHA, C22:6n-3) and arachidonic acid (AA, C20:4n-6) are long-chain polyunsaturated fatty acids (LCPUFAs) with relevant roles in the organism. EPA and DHA are synthesized from the precursor alpha-linolenic acid (ALA, C18:3n-3), whereas AA is produced from linoleic acid (LA, C18:2n-6) through the action of Δ5 and Δ6-desaturases. High-fat diet (HFD) decreases the activity of both desaturases and LCPUFA accretion in liver and other tissues...
