siRNA-mediated VDR knockout in HUVEC. (a) HUVECs were transfected with either control siRNA (10 nM) or VDR siRNA (10 nM), and VDR expression was measured 72 h later by Western blot. (b) Western blot was quantified, and VDR expression is presented as percentage. ^∗p < 0.05, relative to normal cells and cells transfected with control siRNA.
