ABSTRACT
Venous thromboembolism (VTE), the third leading cardiovascular complication, requires more understanding at molecular levels. Here, we have identified miR-145 as a key molecule for regulating thrombus formation in venous thrombosis (VT) employing network based bioinformatics approach and in vivo experiments. Levels of miR-145 showed an inverse correlation with thrombus load determined by coagulation variables. MiRNA target prediction tools and in vitro study identified tissue factor (TF) as a target gene for miR-145. The restoration of miR-145 levels in thrombotic animals via in vivo miR-145 mimic delivery resulted in decreased TF level and activity, accompanied by reduced thrombogenesis. MiR-145 levels were also reduced in VT patients and correlated with increased TF levels in patients, thereby, confirming our preclinical findings. Our study identifies a previously undescribed role of miRNA in VT by regulating TF expression. Therefore, restoration of miR-145 levels may serve as a promising therapeutic strategy for management of VT.
