Abstract
Objectives: Deep-venous thrombosis (DVT) refers to abnormal blood clotting in the deep vein cavity, and post-thrombotic syndrome (PTS) is the most frequent complication. The study explored the impact of microRNA 181b-5p on DVT progression based on human umbilical vein endothelial cells (HUVECs).
Methods: Levels of miR-181b-5p were examined in 150 cases with acute lower extremity DVT. ROC curve and K-M plot were drawn for clinical value assessment. The role of miR-181b-5p in HUVECs viability, migration, apoptosis, inflammatory response and adhesion factors' release was investigated. Target gene of miR-181b-5p was predicted, and its role in cell function was explored.
Results: Low-expressed miR-181b-5p showed favorable diagnostic performance in differentiating DVT with the AUC of 0.948. Patients with low miR-181b-5p had a high incidence of PTS. miR-181b-5p overexpression promoted HUVECs' viability and migration, while inhibiting cell apoptosis and release of inflammatory and adhesion cytokines. As the target gene of miR-181b-5p, HEY2 overexpression reversed the role of miR-181b-5p in HUVECs.
Conclusion: MiR-181b-5p serves as a potential biomarker for DVT diagnosis and PTS development. Overexpression of this miRNA targeted HEY2 to alleviate endothelial cell damage.
期刊介绍:
Hematology is an international journal publishing original and review articles in the field of general hematology, including oncology, pathology, biology, clinical research and epidemiology. Of the fixed sections, annotations are accepted on any general or scientific field: technical annotations covering current laboratory practice in general hematology, blood transfusion and clinical trials, and current clinical practice reviews the consensus driven areas of care and management.
