实验参考方法
In Vitro | In vitro activity: Calcifediol induced CYP24A1 expression with EC50 at 70 nM. Calcifediol stimulated the expression of thrombomodulin with EC50 at 10-100 nM. Confocal microscopy revealed that calcifediol at 0.1 - 10 μM induced VDR translocation into the nucleus dose-dependently; the VDR localization pattern was similar in cells treated with calcitriol. |

In Vivo | Spontaneously hypertensive rats and normotensive Wistar-Kyoto (WKY) rats were injected with either 50 ng/d calcifediol or vehicle alone for 3 days. Decreased calbindin-D9K and cellular Ca2+ flux were observed in control SHR. Calcifediol increased total cell and brush border calbindin-D9K. In contrast, Ca2+ flux, which increased in vit-D animals, remained lower in SHR for plasma calcitriol levels similar to those in WKY rats. |
