Primary Human Osteoblasts in Response to 25-Hydroxyvitamin D3, 1,25-Dihydroxyvitamin D3 and 24R,25-Dihydroxyvitamin D3
The most biologically active metabolite 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) has well known direct effects on osteoblast growth and differentiation in vitro. The precursor 25-hydroxyvitamin D3 (25(OH)D3) can affect osteoblast function via conversion to 1,25(OH)2D3, however, it is largely unknown whether 25(OH)D3 can affect primary osteoblast function on its own. Furthermore, 25(OH)D3 is not o...
متن کاملApoptosis Induction by 1 ,25-Dihydroxyvitamin D3 in Prostate Cancer
Calcitriol [1 ,25-dihydroxyvitamin D3] is the natural ligand of the vitamin D receptor (VDR). Using cultured prostate cancer (PC) cell lines, LN-CaP and ALVA-31, we studied the effects of 1 ,25(OH)2-Vitamin D3 (VD3) on expression of several apoptosis-regulating proteins including: (a) Bcl-2 family proteins (Bcl-2, Bcl-XL, Mcl-1, Bax, and Bak); (b) the heat shock protein 70-binding protein BAG1L...
متن کاملThe 24-hydroxylation of 1,25-dihydroxyvitamin D3.
The production of 1,24,25-trihydroxyvitamin D3 in vivo in vitamin D-deficient rats has been demonstrated from either 25-hydroxyvitamin D3 or 1,25-dihydroxyvitamin D3. The stereochemical configuration of the hydroxyl on the 24 position of 1,24,25-trihydroxyvitamin D3 has also been unambiguously established to be R. Nephrectomy failed to eliminate the conversion of 1,25-dihydroxyvitamin D3 to the...
متن کاملOral Calcium Boluses for Parturient Dairy Cows
1 Interpretative Summary: Effect of oral calcium supplementation on early lactation health 1 and milk yield in commercial dairy herds. By Oetzel and Miller, page 000. Low blood 2 calcium often occurs in older cows around calving and impairs subsequent health and milk yield. 3 Second lactation or greater cows in 2 commercial dairies with effective milk fever prevention 4 were divided into contro...
متن کاملRegulation of 25-hydroxyvitamin D3-1 -hydroxylase and production of 1 ,25-dihydroxyvitamin D3 by human dendritic cells
25-Hydroxyvitamin D3-1 -hydroxylase (25(OH)D3-1 -hydroxylase), the key enzyme of 1 ,25-dihydroxyvitamin D3 (1,25(OH)2D3) production, is expressed in monocyte-derived macrophages (MACs). Here we show for the first time constitutive expression of 25(OH)D3-1 -hydroxylase in monocyte-derived dendritic cells (DCs), which was increased after stimulation with lipopolysaccharide (LPS). Accordingly, DCs...
