Alcoholic Fatty Liver Disease

Early detection of insulin resistance (IR) or non-alcoholic fatty liver disease (NAFLD) is crucial to preventing future risks of developing chronic diseases. The Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), Liver Fat Score (LFS), and Fatty Liver Index (FLI) are generally employed to measure severity stages of IR and NAFLD. The study of gene expressions could explain the molecular mechanisms that occur early on in IR and NAFLD; thus providing potential early markers for both diseases. This study was conducted to evaluate the gene expressions that could potentially be early markers of IR and NAFLD. All participants (n = 21) had normal blood glucose and were categorized as without hepatosteatosis (n = 10), at higher risk of hepatosteatosis (n = 6), and hepatosteatosis (n = 5). Gene expression analysis was performed using the 2-∆∆CT relative quantification method. There were significant differences in galnt2 (p < 0.002) and sirt1 (p < 0.010) expression between the first and the third tertiles of HOMA-IR; and in ptpn1 (p < 0.012) expression between the first and the second tertiles of LFS. In conclusion, the expressions of galnt2 and sirt1 could be used as early markers of IR, while the expression of ptpn1 could be employed as an early marker of NAFLD.

Observational studies indicate that selenium may contribute to the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Transcriptomic exploration of the aetiology and progression of NAFLD may offer insight into the role selenium plays in this disease. This study compared gene expression levels of known selenoprotein pathways between individuals with a healthy liver to those with NAFLD. Publicly available gene expression databases were searched for studies that measured global gene expression in liver samples from patients with steatosis and non-alcoholic steatohepatitis (NASH) and healthy controls (with [HOC] or without [HC] obesity). A subset of five selenoprotein-related pathways (164 genes) were assessed in the four datasets included in this analysis. The gene TXNRD3 was less expressed in both disease groups when compared with HOC. SCLY and SELENOO were less expressed in NASH when compared with HC. SELENOM, DIO1, GPX2, and GPX3 were highly expressed in NASH when compared to HOC. Disease groups had lower expression of iron-associated transporters and higher expression of ferritin-encoding sub-units, consistent with dysregulation of iron metabolism often observed in NAFLD. Our bioinformatics analysis suggests that the NAFLD liver may have lower selenium levels than a disease-free liver, which may be associated with a disrupted iron metabolism. Our findings indicate that gene expression variation may be associated with the progressive risk of NAFLD.

Abstract Objectives The prevalence of non-alcoholic fatty liver disease (NAFLD) in children has increased over the past decades, creating a need for animal models that recapitulate the features of the pediatric disease. Iberian pigs have a leptin-resistant phenotype characterized by hyperleptinemia, hyperphagia, and extreme adipogenesis. We hypothesized that neonatal Iberian pigs fed a high-fat high-fructose (HFF) diet will develop a pattern of liver injury resembling pediatric NAFLD. In addition, we sought to determine if a mixture of probiotics would prevent the disease. Methods Animals were fed 1 of 4 diets containing (g/kg body weight × d) 0 g fructose, 11 g fat and 199 kcal (CON-N; n = 8), 22 g fructose, 16 g fat and 300 kcal (HFF-N; n = 6), CON + probiotic (CON-P; n = 6), or HFF + probiotic (HFF-P; n = 6) every 6 h for 70 d. The probiotic mixture (6.2 × 104cfu/mL) contained Pediococcus, Lactobacillus and Bacillus. Body weight was recorded every 3 d. Serum markers of liver injury and dyslipidemia were measured on d 65 at 2 h post feeding. Fasting leptin, insulin, glucose and homeostatic model assessment (HOMA) values were assessed on d 70. Liver tissue was collected on d 70 for histology, triacylglyceride (TG) quantification, and gene expression of tumor necrosis factor (TNF) α, tumor growth factor (TGF) β, interleukin (IL) 1α, peroxisome proliferator-activated receptor (PPAR) γ, carbohydrate-responsive element-binding protein (ChREBP) and sterol regulatory element-binding protein (SREBP) 1c. Results Body weight was higher in CON-P, and insulin and HOMA values in HFF-P and CON-P (P ≤ 0.05). Leptin, alanine and aspartate aminotransferases, alkaline phosphatase, lactate dehydrogenase and total bilirubin were increased (P ≤ 0.001), and high and low density lipoproteins decreased (P ≤ 0.05) in HFF-N and HFF-P. Livers in HFF-P and HFF-N had higher relative weight and TG (P ≤ 0.001), micro and macrovesicular steatosis, ballooning degeneration, Mallory-denk bodies, inflammation and necrosis, increased gene expression of TNFα, TGFβ, IL1α and PPARγ (P ≤ 0.001), and decreased ChREBP (P ≤ 0.001). Conclusions Iberian pigs fed a HFF diet recapitulate many pediatric NAFLD-associated features, in the absence of obesity and independently of probiotic supplementation, suggesting a potentially suitable model for pediatric NAFLD research.
