Gastrointestinal absorption of calcium and magnesium

Gastrointestinal absorption of calcium and magnesium" refers to the physiological process by which calcium and magnesium ions are taken up from the intestinal lumen into the bloodstream. This occurs through both passive paracellular (between cells via tight junction proteins such as claudins for Mg2+) and active transcellular (through cells, involving ion channels like TRPM6 for Mg2+) pathways. The process is tightly regulated and influenced by dietary intake, hormones (notably vitamin D and parathyroid hormone), and specific molecular transporters or channels. Disruption can result in clinically significant disturbances of mineral homeostasis, but "gastrointestinal absorption of calcium and magnesium" is not itself a discrete molecular target for drug development[2][3][1]. For a true canonical drug target, you should refer to individual molecular mediators such as: - "Transient receptor potential cation channel subfamily M member 6" (TRPM6) for transcellular magnesium absorption - "Epithelial calcium channel" (such as TRPV6) for transcellular calcium absorption - "Claudin-16" or "Claudin-19" for paracellular transport If you intend to catalog a molecular target, please specify a particular transporter, channel, or receptor involved in calcium or magnesium absorption.

Not applicable to a "target"; however, drugs may act by: - Modulating expression or activity of key ion channels (e.g., TRPM6) - Altering electrochemical gradients affecting paracellular absorption - Regulating hormone levels (parathyroid hormone, vitamin D)[2]
