WebFarnesoid X receptor (FXR) is a key nuclear transcription factor in regulating bile acid (BA) homeostasis (Byun et al., 2024). In liver, FXR can inhibit 7-α-hydroxylase (CYP7A1) expression, thereby inhibiting the synthesis of BA (Duan et al., 2024). CYP7A1 is a rate-limiting enzyme for BA synthesis (Kouno et al., 2024).
