8. detected in chondrocytes of healthy-looking knee cartilage in osteoarthritis patients

9. colorectal cancer (CRC) patients had a higher frequence of insufficient vitamin D and a higher concentration of active vitamin D. These concentration were higher between patients with polymorphic genotypes variants of ApaI and BsmI, CYP24A1 and CYP27B1. Polymorphic genotypes cause a lower correlation between the forms of vitamin D.

13. primary human osteoblasts in the presence of high calcium concentrations increase their CYP27B1 mRNA levels by 1.3-fold

14. The multiple sclerosis-associated regulatory variant rs10877013 affects expression of CYP27B1 and VDR under inflammatory or vitamin D stimuli.

15. Vascular Calcification Induced by Chronic Kidney Disease Is Mediated by an Increase of 1alpha-Hydroxylase Expression in Vascular Smooth Muscle Cells

16. The local regulation of vitamin D in sinonasal tissue during chronic rhinosinusitis may be independent of serum 25(OH)D levels. Vitamin D may be dysregulated at multiple levels, with decreased transcription of the metabolic gene CYP27B1 and increased transcription of the catabolic gene CYP24A1.

17. IL-13 suppressed cyp27b1 expression in CD14(+) cells. IL-13 increased expression of miR-19a in CD14(+) cells. IL-13 suppresses cyp27b1 expression in peripheral CD14(+) cells via up regulating miR-19a expression.

18. Uremic serum increased the intracellular expression of IL-6, IFN-gamma, TLR7, TLR9, VDR, CYP27b1 and CYP24a1

19. Women with Recurrent Miscarriage have a lower level of CYP27B1 expression in chorionic villi and decidua compared with normal pregnant women, suggesting that reduced CYP27B1 expression may be associated with Recurrent Miscarriage.

20. Mutation in CYP27B1 is associated with Vitamin D-Dependent Rickets Type 1.

Mouse (Murine) Cytochrome P450, Family 27, Subfamily B, Polypeptide 1 (CYP27B1) interaction partners

1. Absence of calcitriol does not impair post-lactation bone recovery in Cyp27b1 null mice.

2. AQP-1 was decreased in renal papilla and AQP-4 expressions were increased in proximal tubule by suppressing renin activity or supplement of Vitamin D analogue. After injecting renin into the lateral ventricle of the 1alpha(OH)ase knockout mice, the renin expression level was decreased in the kidney, followed by the decrease of AQP-1 in renal papilla and increase of AQP-4 in proximal tubule

3. Vascular Calcification Induced by Chronic Kidney Disease Is Mediated by an Increase of 1alpha-Hydroxylase Expression in Vascular Smooth Muscle Cells

4. These results reveal that differential regulation of Cyp27b1 expression represents a mechanism whereby 1,25(OH)2D3 can fulfill separate functional roles, first in the kidney to control mineral homeostasis and second in extra-renal cells to regulate target genes linked to specific biological responses.

5. The data indicate that abnormal osteoclastogenesis due to the absence of CYP27B1 expression, consistent with the notion that endogenous metabolism of 25-hydroxyvitamin D optimizes osteoclastogenesis and ameliorates the resulting activity of mature osteoclasts.

6. The absence of 25-hydroxyvitamin D3-1alpha-hydroxylase potentiates the suppression of EAE in mice by ultraviolet light.

7. Cyp27b1(-/-) mice exhibited hypocalcemia, growth defects, and skeletogenesis dysfunction, similar to Vdr(-/-) mice, but do not display alopecia

8. Findings demonstrate that in-tumor CYP27B1 1-alpha-hydroxylase activity plays a crucial role in controlling early oncogene-mediated mammary carcinogenesis events, at least in part by modulating tumoral cell NF-kappaB p65 nuclear translocation.

9. the effect of 25-hydroxyvitamin D-1-alpha-hydroxylase on the atherosclerosis disease both in apolipoprotein (apo) E-/- mice and wild-type mice, was investigated.

10. P450C1 alpha deficiency results in abnormal calcium handling and cardiac dysfunction in mice with defective vitamin D signaling.

13. Data show that the absence of either of the two key hydroxylases, vitamin D 25-hydroxylase (CYP2R1) or vitamin D 25-hydroxyvitamin D-1alpha-hydroxylase (CYP27B1)neither inhibits nor enhances the development of experimental autoimmune encephalomyelitis (EAE).

14. These results confirm the expression of vitamin D receptor and Cyp27b1 in vivo and suggest a potential role for vitamin D(3) in skeletal muscle regeneration following injury.

15. Bone formation parameters were increased significantly in all pups fed by dams on the rescue diet but were still lower in 1alpha(OH)ase(-/-) pups than in 1alpha(OH)ase(+/-) pups.

16. 1alpha-hydroxylase may have a role in enhanced radiosensitivity

17. regulation of bone CYP27B1 is unique from that in the kidney, and may play an important role in bone formation

18. study shows CYP27B1 can hydroxylate 25-hydroxyvitamin D2 & 25-hydroxyvitamin D3 associated with phospholipid membranes; low activity found at higher membrane levels of 25-hydroxyvitamin D; substrate inhibition may contribute to enzyme activity regulation

19. findings demonstrate that regulation of both the 25-hydroxyvitamin D-1 alpha-hydroxylase and 25-hydroxyvitamin D-24-hydroxylase genes by phosphorus is disordered in hypophosphatemic mice at the level of renal mRNA expression
