Fig. 1

Vitamin D3 (5 × 105 IU kg−1) was administered for 3 days, and mice were euthanized on the ninth day. a Vitamin D3 induced MDM2 expression (90 kDa band) in the mouse aorta. b Western blot analysis showing Mdm2, Runx2, and Hdac1 in aortas from Mdm2fl/fl (wild-type) and SM22α-cre;Mdm2fl/fl (VSMC-specific Mdm2 knockout) mice. c Aortas were stained with Alizarin red S. d Changes in the aortic calcium content. The data were shown as the mean ± s.e.m. values. P values for the different comparisons are shown in the figure (n = 4).
