Combination of s-methyl cysteine and protocatechuic acid provided greater lipid-lowering and anti-inflammatory effects in mice liver against chronic alcohol consumption

Objective(s): Protective effects of s-methyl cysteine (SMC) alone, protocatechuic acid (PCA) alone, and SMC plus PCA against chronic ethanol consumption induced hepatic steatosis and inflammation were investigated.  Materials and Methods: Mice were divided into six groups: normal diet (ND) group, Lieber-DeCarli liquid diet without ethanol (LD diet) group, LD diet with ethanol (LED diet) group, SMC group (LED diet plus ۰.۲۵% SMC), PCA group (LED diet plus ۰.۲۵% PCA), and SMC+PCA group (LED diet plus ۰.۱۲۵% SMC + ۰.۱۲۵% PCA).  After ۸ weeks of supplementation, blood and liver were used for analysis.  Results: Biochemical and histological data showed that SMC plus PCA led to a greater reduction in lipid droplets in the liver than SMC or PCA treatment alone.  SMC plus PCA resulted in greater suppression in hepatic mRNA expression of peroxisome proliferator-activated receptor-gamma, sterol regulatory element-binding protein ۱c, stearoyl-CoA desaturase-۱, cyclooxygenase-۲, and myeloperoxidase than SMC or PCA treatment alone.  SMC plus PCA led to a greater decrease in hepatic reactive oxygen species and inflammatory cytokine levels than SMC or PCA treatment alone.  Conclusion: These novel findings suggest that the combination of SMC and PCA was a potent remedy for alcoholic liver disorders.
