High-fat diet stimulates the gut pathogenic microbiota and maintains hepatic injury in antibiotic-treated rats.

High-fat diet stimulates the gut pathogenic microbiota and maintains hepatic injury in antibiotic-treated rats. Cell Mol Biol (Noisy-le-grand). 2018 Jan 31;64(1):103-106 Authors: Al-Daihan S, Ben Bacha A, Al-Dbass AM, Alonazi MA, Bhat RS Abstract The gut and the liver are closely linked to each other, as changes in the gut microbiota can play a significant role in the development of many liver diseases. Gut bacteria respond rapidly to changes in diet and thus can affect the liver through their metabolites. The impact of a high lipid diet on the liver in the presence of an altered gut flora modulated by ampicillin was investigated. The study was performed on 30 male Western albino rats randomly divided into 3 groups: control (phosphate buffered saline treated), group II (ampicillin 50 mg/kg for three weeks to induce microbiota alterations and fed on standard diet) and group III (same dose of ampicillin and fed on a lipid rich diet). Stool samples were collected for qualitative determination of bacteria. Serum hepato-specific markers, in addition to Glutathione (GSH), Lipid peroxidase (MDA), Glutathione-S- transferase(GST), and vitamin C in liver tissues, were measured. Altered gut microbiota significantly increased the level of the hepato-specific marker MDA and reduced the GST, GSH and vitamin C levels. However, animals fed a lipid rich diet displayed a more significant shift in hepatic markers and antioxidants. Moreover, a new switch in composition of th...

Nonalcoholic fatty liver disease (NAFLD) arises from mitochondrial dysfunction under sustained imbalance between energy intake and expenditure, but the underlying mechanisms controlling mitochondrial respiration have not been entirely understood. Heterotrimeric G proteins converge with activated GPCRs to modulate cell-signaling pathways to maintain metabolic homeostasis. Here, we investigated the regulatory role of G protein α12 (Gα12) on hepatic lipid metabolism and whole-body energy expenditure in mice. Fasting increased Gα12 levels in mouse liver. Gα12 ablation markedly augmented fasting-induced ...

This study aims to investigate XKQ mechanisms on diabetes and diabetic liver disease by using the KKAy mice model. Our results indicate that XKQ can significantly reduce food and water intake. XKQ treatment also remarkably decreases both the fasting blood glucose and blood glucose in the oral glucose tolerance test. Additionally, XKQ can significantly decrease the serum alanine aminotransferase level and liver index and can alleviate the fat degeneration in liver tissues. Moreover, XKQ can ameliorate insulin resistance and upregulate the expression of IRS-1, PI3K (p85), p-Akt, and GLUT4 in the skeletal muscle of KKAy mice....

(Children's Hospital Colorado) Children's Hospital Colorado (Children's Colorado) pediatric gastroenterologist, Michael Narkewicz, MD, recently shared results of the Prospective Study of Ultrasound to Predict Hepatic Cirrhosis in Cystic Fibrosis (PUSH), which sought to determine if liver ultrasounds could identify children and adolescents with cystic fibrosis who are at greater risk of developing advanced liver disease.

Integral, biochemical, and morphological parameters and concentrations of vitamins, particularly lipid soluble vitamins, were analyzed in female mice of inbred DBA/2J line, outbred ICR-1 (CD-1) line, and DBCB tetrahybrid mice on thein vivo model of metabolic syndrome induced by consumption of 30% sucrose for 2 days. In contrast to inbred and outbred lines, DBCB tetrahybrid mice developed abdominal obesity, hypercholesterolemia, and pronounced morphological picture of fatty liver disease. The lipid-coupled transport of vitamin E to the liver is also enhanced in these animals, which compensated decreased supply of vitamin E ...

Hepatocellular carcinoma (HCC) is mainly associated with chronic liver disease. Indeed, its incidence is highest in Asia and Sub-Saharan Africa, where chronic hepatitis B virus infection is endemic. Until recently, the hepatitis C virus was the leading cause of HCC, but non-alcoholic fatty liver disease (NAFLD) is now emerging as a major risk factor for HCC, especially in Western countries [1-3]. Obesity and metabolic disorders represent the most important risk factors for HCC and currently account for 36.6% of HCC cases in the US.

AbstractPurpose of reviewLike the rest of the gastrointestinal tract, the small intestine is colonised by microbes, but how this “microbiome” affects the immune system and digestive functions has largely been overlooked, especially in the “omics” era. Here, we present recent findings that show that the diversity, density and interactions of these microbes in the small intestine can play an important role in the pathog enesis of a number of gastrointestinal and extraintestinal disorders.Recent findingsChanges in the small intestinal mucosa-associated microbiota (SI-MAM) have been shown to occur with ...

The European Association for the Study of the Liver (EASL) read with interest the letter to the Editors by Stamm et al. The authors of the letter conclude that “the 12-week, single-tablet regimen of sofosbuvir/velpatasvir […] is a highly effective treatment for all patients with compensated liver disease, irrespective of genotype, extent of liver fibrosis or prior interferon treatment history”. This statement is too simplistic as the combination of s ofosbuvir and velpatasvir without ribavirin is suboptimal in patients with cirrhosis infected with HCV genotype 3 carrying the Y93H resistance-associated su...
