Figure 4. Gene expression for two types of 1,25(OH)₂D₃ receptors in wild type and heterozygous mice.

RNA was isolated from the livers of wild type and heterozygous mice at 5, 10, 15, and 30-weeks of age. The gene expression of Pdia3 (A) and nVdr (B) were analyzed by real-time PCR and normalized to S18. N = 6, *P<0.05 vs. wild type, ^# P<0.05 vs. week 5.
