Deep vein thrombosis (DVT) is a common postoperative complication of orthopaedic surgery with a complex pathogenesis mechanism. The effect of the miR-2467-3p/acting-binding LIM protein 1 (ABLIM1) axis on thrombus formation and human vascular endothelial cells (HUVECs) progression was evaluated aiming to identify a novel potential biomarker of DVT. DVT rat models were established by inferior vena cava stenosis. The expression of the miR-2467-3p/ABLIM1 axis was analyzed by PCR. HUVECs were induced with oxidative low-density lipoprotein (ox-LDL). Cell growth and motility were assessed by cell counting kit 8 (CCK8) and Transwell assay. The inflammation and oxidative stress were estimated by proinflammatory cytokines and generation of MDA and reactive oxygen species (ROS). ABLIM1 was downregulated in DVT rats. Overexpressing ABLIM1 could suppress the formation of thrombosis and alleviate inflammation and oxidative stress. In HUVECs, ox-LDL induced significantly increased miR-2467-3p and decreased ABLIM1, and miR-2467-3p could negatively regulate ABLIM1. The knockdown of miR-2467-3p could alleviate the inhibited cell growth and motility by ox-LDL, and the inflammation and oxidative stress were also attenuated. While silencing could reverse the effect of miR-2467-3p on ox-LDL-induced HUVECs. The miR-2467-3p/ABLIM1 axis regulates the occurrence and development of DVT through modulating HUVECs inflammation and oxidative stress.
深静脉血栓形成(DVT)是骨科手术后常见的并发症,其发病机制复杂。评估了miR-2467-3p/肌动蛋白结合LIM蛋白1(ABLIM1)轴对血栓形成和人血管内皮细胞(HUVECs)进展的影响,旨在确定一种新的潜在DVT生物标志物。通过下腔静脉狭窄建立DVT大鼠模型。采用PCR分析miR-2467-3p/ABLIM1轴的表达。用氧化型低密度脂蛋白(ox-LDL)诱导HUVECs。通过细胞计数试剂盒8(CCK8)和Transwell实验评估细胞生长和迁移能力。通过促炎细胞因子以及丙二醛和活性氧(ROS)的生成来评估炎症和氧化应激。ABLIM1在DVT大鼠中表达下调。过表达ABLIM1可抑制血栓形成,减轻炎症和氧化应激。在HUVECs中,ox-LDL诱导miR-2467-3p显著增加,ABLIM1减少,且miR-2467-3p可负向调节ABLIM1。敲低miR-2467-3p可减轻ox-LDL对细胞生长和迁移能力的抑制,炎症和氧化应激也随之减轻。而沉默ABLIM1可逆转miR-2467-3p对ox-LDL诱导的HUVECs的作用。miR-2467-3p/ABLIM1轴通过调节HUVECs的炎症和氧化应激来调控DVT的发生发展。
