Figure S4. The efficiency of knockdown of VPO1 by shRNA. We used four shRNA

TargetSeqs against VPO1 to establish the VPO1-shRNA VSMCs and found that the second sequence had the best efficiency to inhibit the VPO1 expression. We therefore used the second shRNA TargetSeq to establish the VPO-shRNA VSMCs in the sequent experiments.
