Figure 1: VPS9D1-AS1 level is elevated in prostate cancer. (a) Volcano plot of differentially expressed lncRNAs in prostate cancer in The Cancer Genome Atlas (TCGA) database, in which upregulated and downregulated lncRNAs in prostate cancer were represented by red dots and green dots, respectively. (b) Specific expression of VPS9D1-AS1 in prostate cancer and normal groups in TCGA database, with normal tissues shown with green and prostate cancer tissues shown with red. (c) In quantitative real-time reverse transcription polymerase chain reaction assay, VPS9D1-AS1 expression of RWPE-1, VCaP, PC-3, and DU-145 cells. *P < 0.05 relative to RWPE-1 group, n = 3.
