Gulated genes soon after Alivec knockdown. (E ) RT-qPCR of 22 validation of indicated chondrogenic genes after Alivec knockdown in RVSMCs treated AngII (one hundred nM, 3 h). Data presented as mean SD, one-way ANOVA followed by Tukey’s post-hoc test and p 0.01 and p 0.001 vs. indicated groups) n = 3 biological replicates.cipitation (ChIP) assays with all the Sox9 antibody. ChIP-qPCR showed enrichment of Sox9 in the predicted Sox9-binding area, upstream in the Alivec TSS, as compared with sevRT-qPCR validation of microarray data confirmed downregulation of Acan and the manage pcDNACtrl plasmid-transfected cells (Figure 5B). Transfection of(Figure 3E ), following eral other chondrogenic genes, including Tnfaip6, Runx1, Olr1 and Spp1 RVSMCs using the siRNAs targeting Sox9RVSMCs. decreased the Sox9 protein and transcript levels inwith the Alivec knockdown in (siSox9), Additionally, Acan downregulation is consistent controland AngII-treated cells (Figure 5C,D). Sox9 knockdown also decreased the AngII-induced identified part of lncRNAs in regulating adjacent genes (Figure 3B). expression of Alivec and Acan (Figure 5E,F). Conversely, the overexpression ofof Alivec inConversely, in gain-of-function experiments, transient overexpression Sox9 utilizing the pcDNASox9levels of Acan, Runx1,increasedOlr1 and Runx2, relative controlcontrols creased mRNA plasmid in RVSMCs Tnfaip6, Alivec and Acan vs. the towards the vectortransfected cells (Figure 5G ). These benefits demonstrate that Sox9 can regulate Alivec and (Figure 4A ). Together, these benefits demonstrate that lncRNA Alivec plays a key part in Acan expression in response to AngII in RVSMCs. the regulation of AngII-induced chondrogenic genes in RVSMCs.Figure four. Alivec overexpression promotes and its knockdown inhibits the chondrogenic/osteogenic phenotype in RVSMCs. Figure 4.
