Abstract

Objectives: In cardiovascular disease, deep vein thrombosis is one of the vital symptoms causing pulmonary thromboembolism. However, the pathogenesis of deep vein thrombosis is still not clear. One of the critical factors leading to deep vein thrombosis is the platelet aggregation that is mediated by a set of key genes including platelet membrane protein coded by platelet glycoprotein Ib alpha chain (GPIBA).

Methods: Deep vein thrombosis model was established according to the previous protocol, and venous blood and thrombi were collected for further analysis.

Results: The dynamic changes of GPIBA and coagulation factor, von Willebrand factor, were observed in deep vein thrombosis models. Meanwhile, critical proteins participating in adhesion and binding of platelets such as epithelial membrane protein 2 (EMP2), vascular cell adhesion protein 1 (VCAM1), immunoreceptor tyrosine-based activation motif 1 (ITAM1), integrin subunit alpha M (ITGAM), or fibronectin were also differentially expressed in deep vein thrombosis models.

Conclusions: Application of heparin could reverse these dynamic changes in deep vein thrombosis models. Thus, we explained the potential synergic role of GPIBA and von Willebrand factor in regulating the occurrence of deep vein thrombosis and provide therapeutic target against cardiovascular disease.

Keywords: Deep vein thrombosis; GPIBA; platelet; von Willebrand factor.
