【 摘 要 】

Aim: To investigate the prophylactic efficacy of gut microbiota-based treatments on nonalcoholic steatohepatitis (NASH) management via modulation of Hippo signaling pathway-related genes (YAP1, LATS1 and NF2), and their epigenetic regulators (miR-1205 and lncRNA SRD5A3-AS1) retrieved from in-silico data analysis. Materials & methods: Histopathological, biochemical, molecular and immunohistochemistry analyses were used to assess the effects of multistrain probiotic mixture and prebiotic inulin fiber on high sucrose high fat (HSHF) diet-induced NASH in rats. These treatments were administered orally either alone or in combination, along with HSHF diet. Results: Both probiotic mixture and prebiotic inulin fiber attenuated steatosis, inflammation and fibrosis grades in HSHF diet-induced NASH rats. Moreover, the applied treatments significantly prevented the elevation of serum liver enzymes and improved lipid panel. At the molecular level, both treatments down-regulated hepatic YAP1 mRNA and miR-1205 expressions, and concomitantly up-regulated the expression of hepatic LATS1& NF2 mRNAs and the lncRNA SRD5A3-AS1. At the protein level, both treatments decreased the hepatic content of the inflammatory marker IL6 and the fibrotic marker TGFβ1. Moreover, an observable reduction in α-SMA together with noticeable elevation in LATS1/2 protein expression levels were detected in liver sections compared to the untreated rats. Conclusion: Probiotic mixture and prebiotic inulin fiber, either alone or in combination, attenuated NASH progression and ameliorated both fibrosis and hepatic inflammation in the applied animal model. The produced effect was correlated with modulation of the retrieved (YAP1, LATS1 and NF2) – (miR-1205) – (lncRNA SRD5A3-AS1) RNA panel.
