This was the first study that examined the effects of oat β-glucan and inulin on diet-induced nonalcoholic steatohepatitis (NASH) in circadian-disrupted (CD)-male C57BL/6J mice. CD intensified NASH, significantly increasing alanine aminotransferase and upregulating hepatic tumor necrosis factor α (TNFα) and transforming growth factor β 1 (TGFβ1). However, these observations were significantly alleviated by oat β-glucan and inulin treatments. Compared to CD NASH mice, oat β-glucan significantly decreased the liver index, aspartate aminotransferase (AST), and insulin. In prebiotic-treated and CD NASH mice, significant negative correlations were found between enrichment of bacterium Isolate-036 (Harlan), bacterium Isolate-001 (NCI), and after oat β-glucan supplementation with TNFα and TGFβ1 levels; and enrichment of bacterium Isolate-110 (HZI) after inulin supplementation with AST level. In conclusion, oat β-glucan and inulin exhibited similar antiliver injury, anti-inflammatory, and antifibrotic activities but had no effect on cecal short-chain fatty acids and gut microbiota diversity in CD NASH mice.
这是第一项研究,旨在探讨燕麦β-葡聚糖和菊粉对昼夜节律紊乱(CD)雄性 C57BL/6J 小鼠饮食诱导的非酒精性脂肪性肝炎(NASH)的影响。CD 加剧了 NASH,显著增加了丙氨酸氨基转移酶,并上调了肝肿瘤坏死因子α(TNFα)和转化生长因子β 1(TGFβ1)。然而,燕麦β-葡聚糖和菊粉处理显著缓解了这些观察结果。与 CD-NASH 小鼠相比,燕麦β-葡聚糖显著降低了肝指数、天门冬氨酸氨基转移酶(AST)和胰岛素。在益生菌处理和 CD-NASH 小鼠中,在补充燕麦β-葡聚糖后,丰度较高的细菌分离株 036(Harlan)、细菌分离株 001(NCI)与 TNFα和 TGFβ1 水平呈显著负相关,而在补充菊粉后,丰度较高的细菌分离株 110(HZI)与 AST 水平呈显著负相关。总之,燕麦β-葡聚糖和菊粉在 CD-NASH 小鼠中表现出相似的抗肝损伤、抗炎和抗纤维化活性,但对盲肠短链脂肪酸和肠道微生物多样性没有影响。
