Calcium metabolism modulation

Calcium metabolism modulation refers to the complex physiological regulation of calcium ion balance in the body, primarily controlled by hormones such as parathyroid hormone, calcitonin, and active vitamin D (calcitriol). This process involves multiple organs (bone, kidney, gut) and molecular mediators (receptors, channels, transporters, and enzymes) that together maintain plasma calcium within narrow limits, support bone health, and enable key cellular functions. Aberrant regulation can result in disorders of bone, neuromuscular, cardiovascular, or malignant diseases; therefore, drug targets are typically components of calcium signaling or transport pathways, not 'calcium metabolism modulation' as an entity itself [2][4][5][1][3]. Calcium metabolism is regulated by the parathyroid hormone (PTH), calcitonin, and active vitamin D (calcitriol), with bone serving both as a reservoir and effector organ in this process [2][7]. Modulation of calcium metabolism as a drug target generally refers to targeting specific hormones, channels (like voltage-gated or ligand-gated calcium channels), receptors (e.g., calcium-sensing receptor, vitamin D receptor), or enzymes involved in calcium uptake, storage, and release [2][4][5][1]. Therefore, "calcium metabolism modulation" is too broad to be a canonical drug target or receptor and should be broken down into its individual molecular components for structured drug discovery use.
