Evaluation of one-alpha-hydroxy-cholecalciferol alone or in combination with cholecalciferol in CaP deficiency diets on development of tibial dyschondroplasia in broiler chickens

Animal Nutrition, 2018
This experiment was conducted to determine whether dietary cholecalciferol will alleviate a calcium and phosphorous (CaP) deficiency when one-alpha-hydroxy-cholecalciferol, 1α(OH)D3, is supplemented, and to determine the effects of adequate and ...

24R,25-Dihydroxyvitamin D3 Protects against Articular Cartilage Damage following Anterior Cruciate Ligament Transection in Male Rats. [PDF]

PLoS ONE, 2016
Osteoarthritis (OA) in humans is associated with low circulating 25-hydroxyvitamin D3 [25(OH)D3]. In vitamin D replete rats, radiolabeled 24R,25-dihydroxyvitamin D3 [24R,25(OH)2D3] accumulates in articular cartilage following injection of [3H]-25(OH)D3 ...

Influence of dietary 1αlpha-hydroxycholecalciferol, individually or in combination with microbial phytase in calcium and phosphorus deficient diets on growth performance and tibia parameter of Japanese quails (Coturnix japonica)

Acta Scientiarum: Animal Sciences, 2018
The effect of 1α-OH-D3 in calcium-phosphorus (Ca-P) deficient diets on Japanese quail growth performance and tibia parameters was investigated. Eight-day-old (n = 160) newly hatched quails were weighed and randomly allocated to 20 groups, each with 4 ...

Enhanced insulin activity achieved in VDRa/b ablation zebrafish

Frontiers in Endocrinology, 2023
Introduction1α,25-dihydroxyvitamin D3 (1α,25[OH]2VD3) is a hormone known for its key roles in calcium absorption and nutrient metabolism. In teleost fishes, 1α,25(OH)2VD3 insufficiency causes impaired glucose metabolism and lipid oxidation.

1α,25(OH)2-3-epi-vitamin D3, a natural physiological metabolite of vitamin D3: its synthesis, biological activity and crystal structure with its receptor.

PLoS ONE, 2011
BackgroundThe 1α,25-dihydroxy-3-epi-vitamin-D3 (1α,25(OH)2-3-epi-D3), a natural metabolite of the seco-steroid vitamin D3, exerts its biological activity through binding to its cognate vitamin D nuclear receptor (VDR), a ligand dependent transcription ...

Effects of calcium to non-phytate phosphorus ratio and different sources of vitamin D on growth performance and bone mineralization in broiler chickens

Revista Brasileira de Zootecnia, 2016
- A 7 × 2 factorial experiment was designed to test the effects of calcium (Ca) to non-phytate phosphorus (NPP) ratio (1.14, 1.43, 1.71, 2.00, 2.29, 2.57, and 2.86) and different sources of vitamin D (1α-hydroxycholecalciferol (1α-OH-D3) and 25 ...

Co-expression of 1α-hydroxylase and vitamin D receptor in human articular chondrocytes

BMC Musculoskeletal Disorders, 2017
Background The aim was to investigate whether resident chondrocytes in human articular cartilage and in subculture express vitamin D receptor (VDR) and the enzyme that hydroxylates the prohormone 25(OH)D3 to the active hormone 1α,25(OH)2D3, namely 1α ...
