Expression profile of TRPV6 and calbindin D9k in mouse duodenum at baseline (solid bars) on a Ca²⁺-replete diet and plain water and 8 h after ip 1,25(OH)₂D₃ administration (shaded bars). Expression assays were performed as described in the legend for Fig. 8. Data are means ± SE (n = 6–8/genotype per condition). *P < 0.05, baseline vs. 8 h within genotypes. ¶ P < 0.05, baseline comparison, C⁺P⁺ vs. C⁺P⁻. T P < 0.05; W P < 0.05, 8-h comparisons. There were no significant differences for other comparisons for which P values are not given.
