When You Take Exenatide Matters: Morning Dosing Protects the Liver's Internal Clock

Exenatide time-dependently modulates the hepatic circadian clock through CNS GLP-1 receptors. Morning-equivalent dosing (ZT12) counteracted clock disruption from irregular eating; evening-equivalent dosing (ZT0) worsened it. CNS GLP-1 receptor knockdown attenuated these effects.
