Direct and Metabolite Effects: While direct GLP-1R expression on -cells is low, degradation products of GLP-1, such as GLP-1(9-36) , may also inhibit glucagon secretion by activating inhibitory G proteins (Gi/o) and modulating calcium channels (Zheng et al., 2024)

1 Introduction Cholesterol is an organic compound classified within the steroid family, characterized by its distinctive chemical structure: four fused hydrocarbon rings, which provide the molecule with extreme rigidity, a proximal hydrophilic hydroxyl (-OH) group at the 3-position, and a distal hydrophobic hydrocarbon tail extending from the 17-position ( Figure 1A ) ( Figure 1 Cholesterol and its derivatives, including cholesterol esters and oxysterols, play several critical roles in cancer progression ( in vitro assays, comparing them to clinically relevant therapeutic doses to provide a more accurate perspective of their potential impact on cancer treatment

Without the DAC linker, its plasma half-life is approximately 30 minutes meaning each injection produces a discrete GH pulse rather than a sustained elevation

This suggests that vitamin K should be added to future formulations
