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.
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 0.25% SMC), PCA group (LED diet plus 0.25% PCA), and SMC+PCA group (LED diet plus 0.125% SMC + 0.125% PCA). After 8 weeks of supplementation, blood and liver were used for analysis.
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 1c, stearoyl-CoA desaturase-1, cyclooxygenase-2, 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.
These novel findings suggest that the combination of SMC and PCA was a potent remedy for alcoholic liver disorders.
研究S-甲基半胱氨酸(SMC)、原儿茶酸(PCA)单独使用以及SMC与PCA联合使用对慢性乙醇摄入诱导的肝脂肪变性和炎症的保护作用。
将小鼠分为六组:正常饮食(ND)组、不含乙醇的Lieber-DeCarli液体饮食(LD饮食)组、含乙醇的LD饮食(LED饮食)组、SMC组(LED饮食加0.25% SMC)、PCA组(LED饮食加0.25% PCA)和SMC + PCA组(LED饮食加0.125% SMC + 0.125% PCA)。补充8周后,采集血液和肝脏进行分析。
生化和组织学数据表明,与单独使用SMC或PCA相比,SMC与PCA联合使用能使肝脏中的脂滴减少得更多。与单独使用SMC或PCA相比,SMC与PCA联合使用对肝脏中过氧化物酶体增殖物激活受体γ、固醇调节元件结合蛋白1c、硬脂酰辅酶A去饱和酶-1、环氧化酶-2和髓过氧化物酶的mRNA表达具有更强的抑制作用。与单独使用SMC或PCA相比,SMC与PCA联合使用能使肝脏中的活性氧和炎性细胞因子水平下降得更多。
这些新发现表明,SMC与PCA联合使用是治疗酒精性肝病的有效方法。
