The team was hoping to hook a protein (or proteins) that, post-GLP-1 activation, had a particular chemical modification called phosphorylation
Connecting those anecdotal accounts with the fact that there are GLP-1 receptors in the brain in regions that modulate reward processing, and therefore might affect cravings, Al-Aly and his collaborators investigated whether GLP-1s could treat all substance use disorders
Retatrutide remains investigational and is not FDA-approved, so patients should only consider it within legitimate clinical trial settings
Key features Sensitive and easy-to-use colorimetric SEAP bioassay Convenient readout using QUANTI-Blue Solution Strong response to GLP-1R agonists Suitable for kinetic studies (no cell lysis required) Stability guaranteed for 20 passages Applications Therapeutic development Drug screening Release assay Glucagon-like peptide-1 (GLP-1) is an incretin hormone produced primarily by intestinal L-cells in response to rising glucose concentrations
