1 | OBJECTIVE: This study was designed to investigate whether 1, 25-dihydroxyvitamin D3 (1,25-(OH)2D3), produced by activated synovial fluid macrophages, promotes its own catabolism by upregulating vitamin D-24-hydroxylase (24-OHase) in synovial fibroblasts through a vitamin D receptor (VDR) mediated mechanism. | Calcitriol | cytochrome P450 family 24 subfamily A member 1 | Homo sapiens |
2 | OBJECTIVE: This study was designed to investigate whether 1, 25-dihydroxyvitamin D3 (1,25-(OH)2D3), produced by activated synovial fluid macrophages, promotes its own catabolism by upregulating vitamin D-24-hydroxylase (24-OHase) in synovial fibroblasts through a vitamin D receptor (VDR) mediated mechanism. | Calcitriol | cytochrome P450 family 24 subfamily A member 1 | Homo sapiens |

4 | OBJECTIVE: This study was designed to investigate whether 1, 25-dihydroxyvitamin D3 (1,25-(OH)2D3), produced by activated synovial fluid macrophages, promotes its own catabolism by upregulating vitamin D-24-hydroxylase (24-OHase) in synovial fibroblasts through a vitamin D receptor (VDR) mediated mechanism. | Calcitriol | cytochrome P450 family 24 subfamily A member 1 | Homo sapiens |
5 | 1,25-(OH)2D3 increased fibroblast 24-OHase activity, yielding 24-hydroxylated, and more polar, metabolites. | Calcitriol | cytochrome P450 family 24 subfamily A member 1 | Homo sapiens |
6 | CONCLUSIONS: 1, 25-(OH)2D3 is produced by macrophages in vitro at biologically relevant concentrations and can increase its own catabolism by synovial fibroblasts; this effect is probably mediated via upregulation of both synovial fibroblast VDR and 24-OHase. | Calcitriol | cytochrome P450 family 24 subfamily A member 1 | Homo sapiens |
