阿斯提尔 (AST) 通过改善肠道屏障功能和微生物群平衡,显著减少了肠道多. 这种天然化合物在预防多体和潜在的结直肠癌方面表现有前途.
科学领域:
- 胃肠道学和瘤学
- 自然产品化学 自然产品化学
- 微生物组研究 微生物组研究
背景情况:
- 已知阿斯提尔 (AST) 可以缓解肠炎.
- 它对肠的作用,结直肠癌的前体,并未得到充分理解.
研究的目的:
- 为了研究AST对肠道息肉形成的影响.
- 阐明AST作用的基本机制.
主要方法:
- 使用Apcmin/+和AOM/DSS小鼠模型进行体内多胞体评估.
- 使用Caco-2细胞单层和免疫光技术评估肠道屏障的完整性.
- 通过16S rRNA测序和代谢学分析了肠道微生物群和代谢物概况.
主要成果:
- 通过调节炎症,AST在体内减少了50-60%的肠的数量.
- 在体外,AST抑制了癌细胞的增殖,增强了屏障功能 (TEER),并降低了透性.
- AST恢复了肠道微生物群的组成和代谢平衡,其中特定的代谢物影响了炎症和屏障完整性.
结论:
- AST通过增强屏障完整性和调节肠道微生物群-代谢物网络来抑制肠道聚的形成.
- AST的多个向作用表明,它有可能作为肠和结直肠癌的预防剂.
