From: 1,25-Dihydroxyvitamin D3 increases the expression of the CaT1 epithelial calcium channel in the Caco-2 human intestinal cell line

Figure 5

Comparison of the Time Course of CaT1 mRNA and Calbindin D 9K mRNA Induction by 1,25-dihydroxyvitamin D in Caco-2 Cells. Caco-2 cells were treated with 1,25-dihydroxyvitamin D (10 -7 mol/L) for 0, 2, 4, 8 or 24 h. The bar graph indicates the mean (SEM) fold-increase in CaT1 mRNA and calbindin D mRNA expression at each of the time points. The early induction of CaT1 mRNA by 4 h and 8 h following 1,25-dihydroxyvitamin D treatment is not evident for calbindin D mRNA, which did not increase above control until the 24 h time point. The data for CaT1 is the same as presented in Figure 3.
