FXR is expressed at high levels in the liver and intestine. Chenodeoxycholic acid and other bile acids are natural ligands for FXR. Similar to other nuclear receptors, when activated, FXR translocates to the cell nucleus, forms a dimer (in this case a heterodimer with RXR) and binds to hormone response elements on DNA, which up- or down-regulates the expression of certain genes.
The FXR was the base model with solid black paint and laced wheels. The FXRS was the deluxe model with two tone paint, lowered suspension, mag wheels and a backrest. The FXR chassis was essentially an FLT Tour Glide chassis with slightly bigger diameter frame tubes and a more conventional design around the steering head. [10]

Bile acids bind to some other proteins in addition to their hormone receptors (FXR and TGR5) and their transporters. Among these protein targets, the enzyme N-acyl phosphatidylethanolamine-specific phospholipase D (NAPE-PLD) generates bioactive lipid amides (e.g. the endogenous cannabinoid anandamide ) that play important roles in several ...
FXR-dependent processes in liver and intestine were proposed as therapeutic targets in human diseases. [7] Obeticholic acid is the first FXR agonist to be used in human drug studies. [medical citation needed] The FDA has flagged cases of serious liver injury associated with the use of obeticholic acid. [8]

The discovery of farnesoid X receptor (FXR) which is located in the liver, has opened new insights. Bile acid activation of FXR represses the expression of CYP7A1 via, raising the expression of small heterodimer partner (SHP, NR0B2), a non-DNA binding protein.
