Figure Lengend Snippet: EZH2-regulated miR-30a targeted KPNB1 in MPNST cells. (A) Putative miR-30a and miR-30d target site in the wild-type KPNB1 3’UTR region. (B) qRT-PCR analyses of miR-30a in MPNST724 and S462 cells transfected with a negative control or EZH2 siRNA. miR-30a expression was normalized to SNORD47. Data are shown as mean ± SD (n = 3); *p < 0.05, Student t test. (C) qRT-PCR analyses of miR-30a in S462 and MPNST724 cells treated with DZNep for 96 hours. miR-30d expression was normalized to SNORD47. Mean ± SD values are shown (n = 3); *p < 0.05, Student t test. (D) Western blot analyses of KPNB1 and actin in S462 and MPNST724 cells transfected with a negative control (Ctl) or miR-30a (30a) mimics. (E) Luciferase reporter assay showed that miR-30a inhibited wild-type (WT) KPNB1 3’UTR reporter activity but not mutant (MT) KPNB1 3’UTR reporter activity in S462 cells. Mean ± SD values are shown (n = 3); *p < 0.05, Student t test. (F) qRT-PCR analyses of miR-30a expression in normal Schwann cells (NSC) and multiple MPNST cell lines (MPNST724, S462, STS26T, MPNST624, T265, and ST88-14).
