Levels of vitamin D receptor and CYP24A1 in patients with end-stage renal disease

Objective: This study was performed to detect the expression of vitamin D receptor (VDR) and cytochrome P450, family 24, subfamily A, polypeptide 1 (CYP24A1) in 24 end stage renal disease (ESRD) patients and 24 healthy controls. Method: In this study, 24 ESRD patients and 24 healthy controls were included. Results: In our study, the levels of VDR in patients with ESRD were reduced when compared with those from healthy controls (5.20 +/- 0.32 vs 8.59 +/- 1.03; P<0.01). However, the levels of CYP24A1 in ESRD patients were increased than those from healthy controls (50.18 +/- 21 vs 7.78 +/- 1.31; P<0.01). Correlation analysis showed that VDR levels were negatively correlated with CYP24A1 (r=-0.723; P. 0.01). Conclusion: VDR levels were reduced and CYP24A1 levels were increased in patients with ESRD, and VDR levels were negatively correlated with CYP24A1.
