Noncalcemic Actions of Vitamin D Receptor Ligands | Endocrine Reviews | Oxford Academic

The vitamin D analogue EB prevents skeletal metastasis and prolongs survival time in nude mice transplanted with human breast cancer cells. Human TAF II potentiates transcriptional activation by the AF-2s of the retinoic acid, vitamin D3, and thyroid hormone receptors in mammalian cells.

Mocanu V, Vieth R. Human TAF II 55 interacts with the vitamin D 3 and thyroid hormone receptors and with derivatives of the retinoid X receptor that have calcitrikl transactivation properties. Physiological and pharmacological actions of 1, OH 2 D 3 in various systems, along with the detection of VDR in target cells, have indicated potential therapeutic applications of VDR ligands in inflammation rheumatoid arthritis, psoriatic arthritisdermatological indications psoriasis, actinic czlcitriol, seborrheic dermatitis, photoagingosteoporosis postmenopausal and steroid-induced osteoporosiscancers prostate, colon, breast, myelodysplasia, leukemia, head and neck squamous cell carcinoma, and basal cell carcinomacalcitrill hyperparathyroidism, and autoimmune diseases systemic lupus erythematosus, type I diabetes, multiple sclerosis, and organ transplantation.

Circulating hydroxyvitamin D levels indicative of vitamin D ubla Epidemiological studies have shown an inverse correlation between UV light exposure or plasma 1, OH 2 D 3 levels and blood pressure. It is currently an approved treatment for osteoporosis in Japan because the Japanese diet contains less calcium and therefore its side effect is manageable in that population.

The case against ergocalciferol vitamin D2 as a vitamin supplement. Apoptosis is induced by the active metabolite of vitamin D3 and its analogue EB in colorectal adenoma and carcinoma cells: Vitamin D status and ill health: Vitamin D status, parathyroid function, bone turnover, and BMD in postmenopausal women with osteoporosis: As a result, VDR is also known to be involved in cell proliferation, differentiation, and immunomodulation.

Treatment of psoriatic arthritis with oral 1,dihydroxyvitamin D 3: However, treatment was ineffective if administrated at 8 wk of age when insulitis was well established Therefore, the use of hydroxylase inhibitors may enhance the growth inhibitory activity of 1, OH 2 D 3 and its synthetic calcitiol in prostate cancer.

Localization of 1,dihydroxyvitamin D3 receptor VDR expression in human prostate. Demonstration of 1,dihydroxyvitamin D3 receptors in human skin biopsies. Antibacterial effects of vitamin D. Several attempts have calctriol made to synthesize analogs of 1, OH 2 D 3 that exhibit a lower occurrence of hypercalcemia in vivo. J Clin Lab Anal. A number of reports have shown prevention and decrease of vertebral fractures and an increase in total body and spine bone mineral density BMD in osteoporotic women with 1, OH 2 Blua 3 treatment 6— Regulation of lymphokine production and clcitriol T lymphocyte activation by 1,dihydroxyvitamin D3.

Evidence for tissue- and cell-type selective activation of the vitamin D receptor by Ro, a noncalcemic analog of vitamin D3. Comparison of vitamin D2 calcitriiol vitamin Calcigriol supplementation in raising serum hydroxyvitamin D status: Cardiovascular remodelling in coronary artery disease and heart failure. Therefore, it appears that the differential action of 1, OH 2 D 3 in normal and disease state is part and parcel of vitamin D pharmacology.

Krishnan AV, Feldman D. The ensuing immune response recruits T cells and macrophages into the CNS, resulting in localized areas of inflammation and demyelination known as MS lesions. Vitamin D — Effects on skeletal and extraskeletal health and the need for supplementation.

Modulation of cell cycle control by vitamin D3 and its analogue, EBin human breast cancer cells. However, its location can be seen in panel A, which is represented as cylinders.

Success in treating osteoporosis with alfacalcidol is believed to be the result of the ability to administer higher doses of this compound compared with 1, OH 2 D 3before the detection of hypercalcemia Vitamin D and cardiovascular outcomes: Ro decreased bone resorption and increased the number of differentiated osteoblasts in ovariectomized rats and showed approximately 3-fold separation between bone-protecting effect and hypercalciuria.

Furthermore, encouraging results have been obtained with VDR ligands in clinical trials of prostate cancer and hepatocellular carcinoma. Treatment of vitamin D deficiency increases lower limb muscle strength in institutionalized older people independently of regular physical activity: I tof was then calculated by substracting the current recording with Figure 1A and without Figure 1B the inactivating prepulse. Because hydroxylase is involved in 1, OH 2 D 3 degradation, its amplification may lead to decreased serum 1, OH 2 D 3 levels, thus providing a microenvironment conducive for cell growth in the absence of vitamin D-mediated growth control Clinical uses for calciotropic hormones 1,dihydroxyvitamin D3 and parathyroid hormone-related peptide in dermatology: Figure 2B shows mean current-voltage IV curves for I total calcigriol.

Inhibition of c-myc in breast and ovarian carcinoma cells by 1,dihydroxyvitamin D 3retinoic acid and dexamethasone.

Vitamin D deficiency and secondary hyperparathyroidism in the elderly: When EAE was induced in B The molecular events involving cell cycle proteins lead vula vitamin D-dependent induction of apoptosis, bax redistribution, decreased bcl-2 levels, cytochrome c release, polyADP ribose polymerase cleavage, external display of phosphatidylserine, and DNA fragmentation. Based on these observations, 1, OH 2 D 3 and its analogs have been tested either as single agents or calcitril combination with other immunosuppressive agents calcitrioll as cyclosporin in many experimental models, including heart, liverpancreatic islets, and skin The presence of VDR in keratinocytes and the ability of 1, OH 2 D 3 to induce keratinocyte differentiation and inhibit their proliferation also indicated its potential usefulness in squamous cell carcinoma SCC of head and neck and aerodigestive tract.

In addition, VDR ligands have shown some efficacy in limited open clinical trials for prostate cancer, myelodysplasia a precancerous statepsoriatic arthritis, and RA. Mol Nutr Food Res. Current 25 hydroxyvitamin D assays: The conjugated diene connecting the A and C rings nicely fits against the hydrophobic planar Trp stabilized by planar interactions. In this sense, we previously demonstrated that calcitriol can increase L-type calcium current I CaL density in ventricular myocytes Tamayo et al.

Figure 3A left panel shows representative recordings of I tof obtained in 1 myocyte treated with vehicle and in 1 myocyte treated with 10 nM calcitriol a, and Figure 3A right panel shows IV curves for I tof density.
