The Relationship between Th1/Th2 Balance and 1α, 25-Dihydroxyvitamin D3 in Patients with Allergic Rhinitis [PDF]
Objective:With regard to the correlation between T helper1/T helper2 (Th1/Th2) cell balance and 1α,25-dihydroxyvitamin D3, active metabolite of vitamin D, we studied Th1/Th2 cell balance by measuring levels of the cytokines interleukin (IL)-4, IL-10 and ...

Differential Metabolic Stability of 4α,25- and 4β,25-Dihydroxyvitamin D3 and Identification of Their Metabolites. [PDF]
Vitamin D3 (1) is metabolized by various cytochrome P450 (CYP) enzymes, resulting in the formation of diverse metabolites. Among them, 4α,25-dihydroxyvitamin D3 (6a) and 4β,25-dihydroxyvitamin D3 (6b) are both produced from 25-hydroxyvitamin ...

1,25-dihydroxyvitamin-D3 but not the clinically applied marker 25-hydroxyvitamin-D3 predicts survival after stem cell transplantation [PDF]
The serum level of 25-hydroxyvitamin-D3 is accepted as marker for a person’s vitamin D status but its role for the outcome of allogeneic hematopoietic stem cell transplantation (HSCT) is controversially discussed.

Detection of 7-Dehydrocholesterol and Vitamin D3 Derivatives in Honey
20(S)-Hydroxyvitamin D3 (20(OH)D3) is an endogenous metabolite produced by the action of CYP11A1 on the side chain of vitamin D3 (D3). 20(OH)D3 can be further hydroxylated by CYP11A1, CYP27A1, CYP24A1 and/or CYP27B1 to several hydroxyderivatives. CYP11A1

Gene expression profiles in human and mouse primary cells provide new insights into the differential actions of vitamin D3 metabolites. [PDF]
1α,25-Dihydroxyvitamin D3 (1α,25(OH)2D3) had earlier been regarded as the only active hormone. The newly identified actions of 25-hydroxyvitamin D3 (25(OH)D3) and 24R,25-dihydroxyvitamin D3 (24R,25(OH)2D3) broadened the vitamin D3 endocrine system ...

Vitamin D Metabolites and Risk of Cardiovascular Disease in Chronic Kidney Disease: The CRIC Study
Background The ratio of 24,25‐dihydroxyvitamin D3/25‐hydroxyvitamin D3 (vitamin D metabolite ratio [VDMR]) may reflect functional vitamin D activity. We examined associations of the VDMR, 25‐hydroxyvitamin D (25[OH]D), and 1,25‐dihydroxyvitamin D (1,25 ...

Affinity Labeling of the 1α,25-Dihydroxyvitamin D3 Receptor [PDF]
Genomic actions of the calciotropic hormone 1 alpha, 25-dihydroxyvitamin D3 (1,25(OH)2D3) involves a multistep process that is triggered by the highly specific binding of 1,25(OH)2D3 to 1 alpha, 25-dihydroxyvitamin D3 receptor, VDR. In order to study this key step in the cascade, we synthesized 1 alpha,25-dihydroxy[26(27)-3H]vitamin D3-3-deoxy-3 beta ...
