Peptide receptor radionuclide therapy controls inappropriate calcitriol secretion in a pancreatic neuro-endocrine tumor: a case report

BMC Gastroenterology, 2020
Background Hypercalcemia of malignancy is not uncommon in patients with advanced stage cancer. In rare cases the cause of the hypercalcemia is excessive production of calcitriol, the active form of vitamin D.

Physiological Basis for Using Vitamin D to Improve Health

Biomedicines, 2023
Vitamin D is essential for life—its sufficiency improves metabolism, hormonal release, immune functions, and maintaining health. Vitamin D deficiency increases the vulnerability and severity of type 2 diabetes, metabolic syndrome, cancer, obesity, and ...

Characterisation of bovine leukocyte Ig-like receptors [PDF]

, 2012
Leukocyte Immunoglobulin-like receptors (LILR) are innate immune receptors involved in regulating both innate and adaptive immune functions. LILR show more interspecies conservation than the closely related Killer Ig-like receptors, and homologues have ...

Vitamin D and Glomerulonephritis

Medicina, 2021
Vitamin D presents a plethora of different functions that go beyond its role in skeletal homeostasis. It is an efficient endocrine regulator of the Renin–Angiotensin–Aldosterone System (RAAS) and erythropoiesis, exerts immunomodulatory effects, reduces ...

Simultaneous changes in the calcium-sensing receptor and the vitamin D receptor under the influence of calcium and calcitriol [PDF]

Nephrology Dialysis Transplantation, 2008
The regulatory mechanisms of parathyroid hormone (PTH) synthesis are complex, involving calcium, calcitriol, the calcium-sensing receptor (CaR) and the vitamin D receptor (VDR). In this study, the effects of calcium and calcitriol on the simultaneous expression of CaR and VDR mRNA and protein levels were assessed in parathyroid glands cultured in vitro.

[The role of calcium, calcitriol and their receptors in parathyroid regulation].

Nefrologia : publicacion oficial de la Sociedad Espanola Nefrologia, 2009
The mechanism of regulation of Parathyroid hormone (PTH) is complex, and diverse factors are involved: the fundamental ones are calcium, calcitriol and phosphorus. Calcium and calcitriol's mechanism of action takes place through its specific receptors, the calcium-sensing receptor (CaR) and the Vitamin D Receptor (VDR). These two factors have an effect

Effect of Schiff base formation on the function of the calcitriol receptor

Kidney International, 1996
The genomic action of calcitriol is mediated through the interaction of the calcitriol receptor (VDR) with vitamin D response elements (VDREs) of the target genes. We have shown that the interaction of VDRs with VDREs is inhibited by uremic toxins.

Decreased expression of vitamin D receptors in neointimal lesions following coronary artery angioplasty in atherosclerotic swine. [PDF]

PLoS ONE, 2012
Inflammatory cytokines, such as TNF-α, play a key role in the pathogenesis of occlusive vascular diseases. Activation of vitamin D receptors (VDR) elicits both growth-inhibitory and anti-inflammatory effects. Here, we investigated the expression of TNF-α

Inhibition of nuclear uptake of calcitriol receptor by uremic ultrafiltrate

Kidney International, 1994
The biological action of calcitriol is mediated through a hormone-receptor complex interacting with nuclear chromatin. Interaction of the calcitriol receptor (VDR) with VDR response elements produces bioactive proteins which carry out the physiological actions of calcitriol.
