The knowledge and treatment of alcoholic liver disease is still plagued with gaps mostly due to the inherent limitations of research with patients. We developed an animal model for studying liver histopathology, Hsp-chaperones involvement, and response to treatment. The system was standardized using mice to which ethanol was orally administered alone or in combination with Lactobacillus fermentum for 4, 8 and 12 weeks and applying a battery of techniques (histology, immunohistochemistry, Western blotting, real-time PCR, immunoprecipitation, 3-nitrotyrosine labeling) to assess liver pathology and Hsp60, iNOS gene expression and protein levels, and Hsp60 post-translational modifications. Steatosis score, iNOS levels, and nitrosylated proteins (e.g., Hsp60) decreased after probiotic intake reducing considerably ethanol-induced tissue damage However, one may assume that the probiotic tested has a gut protective effect and, possibly, anti-steatotic and antioxidant effects in the liver. Our results provide novel insights that may be taken into account while devising new approaches for treating liver diseases associated with alcohol consumption.
