Expression of vitamin D receptor, CYP27B1 and CYP24A1 hydroxylases and 1,25-dihydroxyvitamin D levels in stone formers.

The expression of vitamin D receptor (VDR) and 1,25-dihydroxyvitamin D [1,25(OH)D] levels exceed the values of controls in some but not all hypercalciuric stone formers (HSF). We aimed to evaluate serum 1,25(OH)D levels, the expression of VDR, CYP27B1, and CYP24A1 hydroxylases in HSF in comparison with normocalciuric stone formers (NSF) and healthy subjects (HS). Blood samples, 24-h urine collections and a 3-day dietary record were obtained from 30 participants from each of the groups.
