VDR expression levels in the caki-1 and 786–0 RCC cell lines with different treatments.

<p>VDR mRNA expression was measured by RT-PCR and was normalized to that of β-actin. VDR protein expression was analysed by WB, and β-actin was used as a loading control. *p <0.05, **p <0.01, ***p <0.001. (A) VDR expression levels in caki-1 cells were higher in 786-O cells. (B) & (C) Overexpression of VDR by infection with the VDR-expressing lentivirus (leVDR) and knockdown of VDR with shRNA lentivirus (shVDR) in caki-1 and 786-O cells.
