Interestingly, despite the lack of metabolic consequence in hepatocyte RAMP2-overexpressing mice, hepatocyte-specific knockdown of the endosomal protein VPS37a within in vitro and ex vivo settings increases ligand-bound GcgR localization into G s accessible endosomes, enhances total G s /cAMP signaling, reduces lysosomal targeting, and alters endosomal localization which when applied in vivo significantly upregulates glucose production and biases hepatic metabolic flux away from fatty acid oxidation [164]

Rapid weight loss can also increase gallstone risk
The approval was supported by results from the SURMOUNT-OSA trial that revealed Zepbound led to a significant reduction in the apnea-hypopnea index at 52 weeks compared to placebo in individuals who were and were not receiving PAP therapy
