Glucose release

"Glucose release" is not a specific molecule, receptor, or canonical therapeutic target. Instead, it refers to the physiological process by which **glucose is released from cells—primarily hepatocytes in the liver—into the bloodstream**. This process is central to maintaining blood glucose levels and involves several molecular mechanisms: - **Glycogenolysis** (breakdown of glycogen into glucose) and **gluconeogenesis** (synthesis of new glucose from non-carbohydrate sources) are the main pathways for endogenous hepatic glucose production[4][6]. - The hormone **glucagon**, secreted by pancreatic alpha cells when blood sugar falls, stimulates these processes in the liver[1][4]. - Only tissues expressing **glucose 6-phosphatase** (mainly liver and kidney) can dephosphorylate intracellular glucose 6-phosphate to free glucose for export into circulation[4][6]. - Glucose transporters such as GLUT2 facilitate bidirectional movement of free glucose across hepatocyte membranes[5][6]. This process is crucial in metabolic diseases like diabetes mellitus; excessive or insufficient hepatic glucose release contributes directly to hyperglycemia or hypoglycemia respectively[1][4]. However, "glucose release" itself does not refer to a single protein or druggable entity but rather a complex physiological event involving multiple enzymes (e.g., glycogen phosphorylase, G6Pase), hormones (insulin/glucagon), and transporters. Because "glucose release" does not correspond to a discrete molecular target but rather describes an outcome/process regulated by many targets, it should not be considered a canonical therapeutic target. If you are seeking information on specific proteins involved in this pathway—such as "Glucagon receptor," "Glucose transporter type 2," or "Glucose 6-phosphatase"—those would be appropriate entries for structured data extraction instead[1][4][6].
