  3. Calcitriol - Wikipedia

    en.wikipedia.org/wiki/Calcitriol

    Calcitriol is a hormone and the active form of vitamin D, normally made in the kidney. [8] [9] [10] It is also known as 1,25-dihydroxycholecalciferol.It binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. [11]

  4. Calcium metabolism - Wikipedia

    en.wikipedia.org/wiki/Calcium_metabolism

    Calcium release from bone is regulated by parathyroid hormone in conjunction with calcitriol manufactured in the kidney under the influence of PTH. Calcitonin (a hormone secreted by the thyroid gland when plasma ionized calcium levels are high or rising; not to be confused with "calcitriol" which is manufactured in the kidney) stimulates ...

  5. Parathyroid gland - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_gland

    Parathyroid hormone (also known as parathormone) is a small protein that takes part in the control of calcium and phosphate homeostasis, as well as bone physiology. Parathyroid hormone has effects antagonistic to those of calcitonin .

  6. Vitamin D - Wikipedia

    en.wikipedia.org/wiki/Vitamin_D

    A third important effect of PTH on the kidneys is stimulation of the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol). [221] This form of vitamin D is the active hormone which promotes calcium uptake from the intestine via the action of calbindin . [ 223 ]

  7. Calcium in biology - Wikipedia

    en.wikipedia.org/wiki/Calcium_in_biology

    Parathyroid hormone secreted by the parathyroid gland regulates the resorption of Ca 2+ from bone, reabsorption in the kidney back into circulation, and increases in the activation of vitamin D 3 to calcitriol. Calcitriol, the active form of vitamin D 3, promotes absorption of calcium from the intestines and bones.

  8. Parathyroid hormone family - Wikipedia

    en.wikipedia.org/wiki/Parathyroid_hormone_family

    Parathyroid hormone (PTH) is a polypeptidic hormone primarily involved in calcium metabolism. The parathyroid hormone-related protein (PTH-rP) is a related protein with predominantly paracrine function and possibly an endocrine role in lactation, as PTHrP has been found to be secreted by mammary glands into the circulation and increase bone ...

    Calcitriol: secosteroid (1,25-dihydroxyvitamin D 3) skin/proximal tubule of kidneys: VDR: Active form of vitamin D 3. Increase absorption of calcium and phosphate from gastrointestinal tract and kidneys inhibit release of PTH. Calcidiol: secosteroid (25-hydroxyvitamin D 3) skin/proximal tubule of kidneys: VDR: Inactive form of vitamin D 3
