Figure Lengend Snippet: Figure 1. Identification of Vegfa as a direct target of miR-29a-3p in VSMCs using bioinformatics and dual-luciferase assay. (A) Venn diagram depicting the overlap of miR-29a-3p target genes predicted by four miRNA target prediction tools: miRTarBase, miRWalk, TargetScan, and miRDB. The box highlights the seven genes identified as common targets across all tools. (B) Sequence alignment of miR-29a-3p with the 3′-UTR region of wild-type and mutated Vegfa mRNA. The predicted binding site and seed region are marked in red. (C) Dual-luciferase reporter assay results for VSMCs co-transfected with a control vector, a vector containing the wild type (WT) Vegfa 3′-UTR sequence, or the MUT Vegfa sequence, along with miR-29a-3p mimics or a negative control miRNA (NT). Relative luciferase activity was measured, and data are presented as mean ± SD from three independent experiments.
Article Snippet: VSMCs recovered by centrifugation were homogenized and separated using 10% sodium dodecyl sulfate-polyacrylamide gel electrophoresis (China National Pharmaceutical Group Corporation Chemical reagent Co., Ltd., China; Cat. #30166428). the proteins were then transferred to polyvinylidene fluoride membranes (Millipore Co., uSa; Cat. #ISEQ00010). the blots were stained with rabbit polyclonal antibodies against VEGFa (1:10,000; Proteintech, uSa; Cat. #19003-1-aP), and mouse monoclonal antibodies against β-actin (1:10,000, Servicebio, China; Cat. #Gb15001), followed by anti-rabbit IgG (1:10,000, SIMubIotECH, China; Cat. #S2001), and anti-mouse IgG horseradish peroxidase conjugates (1:10,000, abclonal, China; Cat. #aS003).
