Ursodeoxycholic acid alleviates aortic aneurysm and dissection through the intestinal farnesoid X receptor/ceramide synthesis 2 axis

The farnesoid X receptor (FXR) is a nuclear receptor mainly expressed in the liver and intestine. In the intestine, FXR plays a crucial role in regulating lipid metabolism, bile acid homeostasis, and intestinal barrier function.Activation of FXR can lead to the regulation of a variety of genes involved in these processes. For example, it can affect the absorption and transport of lipids and bile acids through the intestine,in this paper,we Ursodeoxycholic acid alleviates aortic aneurysm and dissection through the intestinal farnesoid X receptor/ceramide synthesis 2 axis. Chromatin immunoprecipitation DNA-sequencing (ChIP-seq) for FXR in mice intestine.
