Hepatic lipid analysis Liver tissue pieces have been homogenized in ice-cold 26 PBS and lipids have been extracted. Triglycerides were assessed using a kit. Values have been normalized to TNF-a, tumor necrosis factor alpha; IL-1b, interleukin 1 beta; h, human; IL-8R, interleukin 8 receptor; ChREBP, carbohydrate response-element binding protein; ACC1, acetyl-CoA carboxylase 1; FAS, fatty acid synthase. doi:ten.1371/journal.pone.0080169.t001 LGG Ameliorates Non-Alcoholic Fatty Liver Illness species distinct primer for LGG was developed by Brandt and Alatossava. PCR amplification and detection was performed applying an ABI PRISM 7900HT sequence detection method in optical-grade 96-well plates sealed with optical sealing tape. Each and every reaction mixture was composed of 12.five ml of QuantiTect SYBR Green PCR Master Mix, 2 ml primer mix, 9 ml sterile distilled H2O, and 1.five ml stool DNA. For the damaging manage, 2 ml of sterile distilled H2O was added for the reaction option as an alternative to the template DNA solution. A standard curve was created applying the suitable reference organism to quantify the qPCR values into quantity of bacteria/g. The regular curves had been ready inside the exact same PCR assay as for the samples. The fluorescent goods had been detected inside the final step of each cycle. A melting curve evaluation was carried out following amplification to distinguish the 1516647 targeted PCR solution from the non-targeted PCR item. The melting curves had been obtained by slow heating at temperatures from 55 to 95uC at a rate of 0.2uC/s, with continuous fluorescence collection. The information was analyzed using the ABI Prism software. The real-time PCRs were performed in triplicate, and average values have been applied for enumeration. Protein expression To prepare total tissue protein, snap-frozen compact intestine samples had been homogenized within a lysis buffer containing a protease inhibitor mix. Protein lysates have been separated in a 10% SDS-polyacrylamide gel and transferred to HybondTM-P polyvinylidene difluoride membranes. Blots 
were then probed with antibodies against occludin, claudin-1, IkB/pIkB kinase, or ZO-1/2, respectively. The bands were visualized using Super Signal Western Dura kit. To ensure equal loading, all blots have been stained with Ponceau red; signals had been normalized to bactin. Protein bands were analyzed by densitometry applying the Flurochem Software AlphaEaseFS. Lipopolysaccharides assay Portal plasma samples had been heated at 73uC for 20 min. Lipopolysaccharides concentration was determined applying a limulus amebocyte lysate 
assay kit. Human epithelial cell culture The human epithelial cell line caco2 is not only accepted as a model for intestinal barrier but for fructose metabolism also.
