Figure Lengend Snippet: a The targets of miR-149 predicted using the miRDB, starbase and TargetScan databases are shown using Venn diagram. b The KEGG enrichment analysis of these targeted genes. c The predicted complementary sequences of RAP1B and miR-149. d , e Luciferase reporter ( d ) and RNA pull-down assays ( e ) were used to determine the targeting relationship. f , g qPCR ( f ) and western blotting ( g ) were applied to detect RAP1B expression after circPHGDH and miR-149 knockdown. h The RAP1B levels in PCa tissues and para-PCa tissues were detected by qPCR ( n = 51). i The correlation of miR-149 and RAP1B expression in PCa tissues were analyzed using Pearson correlation coefficient. j , k The RAP1B levels in WPMY1 and PCa cell lines were tested by qPCR ( j ) and western blotting ( k ). l The RAP1B-correlated genes were predicted using the LinkedOmics database. m The KEGG enrichment analysis of all RAP1B-correlated genes. n The 22Rv1 and VCap cells were transfected RAP1B overexpression plasmids, the protein levels of RAP1B, phosphorylated (p)-PI3K, PI3K, p-AKT and AKT were detected using western blotting. n = 3. * P < 0.05, ** P < 0.01, *** P < 0.001, ## P < 0.01 versus the sh-circPHGDH + nc inhibitor group.
Article Snippet: Prostatic epithelial cells (WPMY1) and PCa cell lines (22Rv1, DU145, DuCaP, VCaP, LNCaP and C4-2), obtained from the American Type Culture Collection (ATCC), were cultured in Dulbecco’s modified Eagle medium (Thermo Fisher Scientific) supplemented with 10% fetal bovine serum and 1% penicillin–streptomycin at 37 °C in a 5% CO 2 .
