摘要
背景:胆汁酸是胆汁的主要成分之一。最近,它们也被认为是重要的信号分子,不仅通过调节它们自身的合成,而且还发挥作用i。多种代谢性疾病。 目的:研究脱氧胆酸钠(NaDOC)、熊去氧胆酸(UDCA)和利胆酸(LCA)及其组合对肠道Ca2+吸收的影响。制作CL倾听这些BAs在这个生理过程中的作用,概述目前关于肠道Ca2+发生的机制的信息。 方法:检索PubMed数据库至2017年,使用胆汁酸、NaDOC、UDCA、LCA、氧化还原状态、细胞凋亡、自噬和肠钙吸收等关键词。 结果:氧化还原状态的调节、细胞凋亡和自噬是BAS对肠内Ca2+吸收的作用机制。尽管这些机制还没有完全实现最后,我们提供了有关BAS对肠道钙吸收影响的最新知识。 结论:BAS影响肠道对Ca2+的吸收反应,但与BA的类型和剂量有关。当有一个单一的管理,NaDOC有一个抑制的ef。FECT,UDCA是刺激器,而LCA没有任何影响。然而,BAS的组合改变了响应。无论是UDCA还是LCA都能保护肠道免受氧化损伤的影响。D通过阻断氧化/亚硝基应激、凋亡和自噬作用而被NaDOC所阻断。

摘要: Background: Bile acids (BAs) are among the main components of bile. Lately, they are also considered important signaling molecules, not only by regulating their own synthesis, but also having a role in several metabolic diseases.
Objective: In this review we focus on the effect of sodium deoxycholate (NaDOC), ursodeoxycholic (UDCA) and litocholic (LCA) acids and their combination upon the intestinal Ca2+ absorption. To make clear the actions of those BAs on this physiological process, an overview of current information about the mechanisms by which the intestinal Ca2+ occurs is described.
Methods: The PubMed database was searched until 2017, using the keywords bile acids, NaDOC, UDCA and LCA and redox state, apoptosis, autophagy and intestinal Ca2+ absorption.
Results: The modulation of redox state, apoptosis and autophagy are mechanisms that are involved in the action of BAs on intestinal Ca2+ absorption. Although the mechanisms are still not completely understood, we provide the latest knowledge regarding the effect of BAs on intestinal Ca2+ absorption.
Conclusion: The response of the intestine to absorb Ca2+ is affected by BAs, but it is different according to the type and dose of BA. When there is a single administration, NaDOC has an inhibitory effect, UDCA is an stimulator whereas LCA does not have any influence. However, the combination of BAs modifies the response. Either UDCA or LCA protects the intestine against the oxidative injury caused by NaDOC by blocking the oxidative/nitrosative stress, apoptosis and autophagy.
