Chicken-liver hydrolysates (CLHs) have been characterized as performing several biofunctions by our team. This study aimed to investigate if a CLH-based supplement (GBHP01) can ameliorate liver fibrogenesis induced by thioacetamide (TAA) treatment. Our results showed that the TAA treatment caused lower body weight gains and enlarged livers, as well as higher serum ALT, AST, and ALP levels ( < 0.05). This liver inflammatory and fibrotic evidence was ameliorated ( < 0.05) by supplementing with GBHP01; this partially resulted from its antioxidant abilities, including decreased TBARS values but increased TEAC levels, reduced GSH contents and catalase/GPx activities in the livers of TAA-treated rats ( < 0.05). Additionally, fewer nodules were observed in the appearance of the livers of TAA-treated rats after supplementing with GBHP01. Similarly, supplementing GBHP01 decreased fibrotic scars and the fibrotic score in the livers of TAA-treated rats ( < 0.05). Moreover, the increased hepatic IL-6, IL-1β, and TNF-α levels after TAA treatment were also alleviated by supplementing with GBHP01 ( < 0.05). Meanwhile, GBHP01 could decrease the ratio of LC3B II/LC3B I, but upregulated P62 and Rab7 in the livers of TAA-treated rats ( < 0.05). Taking these results together, the CLH-based supplement (GBHP01) can be characterized as a natural agent against liver fibrogenesis.
我们团队已将鸡肝水解物(CLHs)的特征描述为具有多种生物功能。本研究旨在调查基于CLH的补充剂(GBHP01)是否能改善硫代乙酰胺(TAA)治疗诱导的肝纤维化。我们的结果表明,TAA治疗导致体重增加降低和肝脏肿大,以及血清ALT、AST和ALP水平升高(P<0.05)。补充GBHP01可改善这种肝脏炎症和纤维化证据(P<0.05);这部分归因于其抗氧化能力,包括TAA处理大鼠肝脏中TBARS值降低但TEAC水平升高、GSH含量降低以及过氧化氢酶/谷胱甘肽过氧化物酶(catalase/GPx)活性降低(P<0.05)。此外,补充GBHP01后,TAA处理大鼠肝脏外观上观察到的结节减少。同样,补充GBHP01可降低TAA处理大鼠肝脏中的纤维化瘢痕和纤维化评分(P<0.05)。此外,补充GBHP01还可减轻TAA处理后肝脏中IL-6、IL-1β和TNF-α水平的升高(P<0.05)。同时,GBHP01可降低TAA处理大鼠肝脏中LC3B II/LC3B I的比值,但上调P62和Rab7(P<0.05)。综合这些结果,基于CLH的补充剂(GBHP01)可被视为一种抗肝纤维化的天然制剂。
