Circ_0020123, a New Circular RNA Biomarker for Deep Vein Thrombosis in Pregnant Women by Min Cui, Li Wang, PeiRong Xu, LiRong Fu, Rong Hu

Background: Deep vein thrombosis (DVT) commonly occurs among vascular diseases globally, for which circular RNAs (circRNAs) are becoming a promising option by mediating functions of human umbilical vein endothelial cells (HUVECs). Therefore, this study focuses on whether circ_0020123 plays a role in HUVECs.
Methods: Pregnant women with DVT (n = 39) and without DVT (n = 39) were selected as the observation group and control group, respectively. Circ_0020123 expression in serum of pregnant women with DVT was assessed by RT-qPCR. The risk factors of DVT in pregnant women were analyzed by single factor logistic regression. HUVECs were treated with oxidized low-density lipoprotein (ox-LDL) to construct an in vitro model. Cell proliferation, tube formation ability, migration, and apoptosis were determined by cell counting kit-8, tube formation assay, Transwell assay, and flow cytometry. The levels of oxidative stress, inflammatory factors, endothelin-1 (ET-1), and von Willebrand factor (VWF) in cell supernatant were detected.
Results: The mode of delivery (cesarean delivery), postpartum hemorrhage (yes), puerperal bedtime (> 72 hours), and increased circ_0020123 were independent risk factors for DVT in pregnant women. Knockdown of circ_0020123 promoted HUVEC proliferation and angiogenesis in vitro.
Conclusions: Clinical analysis of risk factors for DVT in pregnant women and positive measures for prevention can effectively avoid the formation of DVT. Circ_0020123 is a new circRNA biomarker for DVT in pregnant women.
