Figure Lengend Snippet: Figure 5. lncRNA H19 promoted VSMC proliferation and migration by suppressing miR-125a-3p to induce FLT1 expression (A) Bioinformatics analysis of the binding sites between miR-125a-3p and FLT1. (B) Relative mRNA expression of FLT1 in arteries collected from mouse sham carotid arteries and injured carotid arteries. *P<0.05 versus the sham group (n=5). (C) Western blot analysis of FLT1 in human VSMCs treated with NC or miR-125a-3p mimics. (D) Quantitative analysis of the FLT1 protein level. *P<0.05 versus the NC group (n=3). (E) Western blot analysis of FLT1 in human VSMCs. (F) Quantitative analysis of the FLT1 protein level in (D). *P<0.05 versus the vector group (n=3). (G) Dual-luciferase reporter assay of human 293T cells treated with NC mimics, miR-125a-3p mimics, and the FLT1-WT or FLT1-Mut luciferase reporters. *P<0.05 versus the FLT1 (WT)+NC group; &P<0.05 versus the FLT1(WT)+miR-125a-3p+vector group (n=3). (H) Western blot analysis of FLT1 in human VSMCs infected with vector or FLT1 lentivirus. (I) Quantitative analysis of the FLT1 protein level. *P<0.05 versus the vector group (n=3). (J) The proliferation of human VSMCs infected with vector or FLT1 lentivirus was measured by a CCK-8 assay. *P<0.05 versus the vector group (n=5). (K) The migration of human VSMCs infected with vector or FLT1 lentivirus. Magnification: 100×. (L) Quantitative analysis of the migration distance. *P<0.05 versus vector (n=3).
Article Snippet: Cell culture The human aortic vascular smooth muscle cell line T/G HA-VSMCs (ATCC CRL-1999) and human embryonic kidney 293T cells (ATCC CRL-3216) were cultured in Dulbecco’s modified Eagle’s medium (DMEM)/Ham’s F12 medium (Gibco, Carlsbad, USA) supplemented with 10% fetal bovine serum (FBS; PAN Biotech, Aidenbach, Germany) and 1% penicillin/streptomycin sulfate in a 5% CO2 incubator at 37°C.
