Hypoxia-dependent proteins and VTE
Venous thrombi originate in the valve pocket of the deep veins, in a milieu that is characterized by intermittent hypoxia and vortex flow (stasis). To study the involvement of hypoxia in the pathogenesis of VTE, we have recently characterized endothelial cells and monocytes responses to sustained and intermitted (pulsatile) hypoxia by multi-color flow cytometry and RNA seq. The main aim of the project is to identify hypoxia-induced proteins that are causally related to VTE and to unravel novel mechanisms for the initiation of disease. For this, we will identify hypoxia-induced proteins from a whole transcriptome analysis of hypoxic endothelial cells and monocytes. The association between hypoxia induced proteins and VTE will be investigated in a case-cohort study. Protein quantitative loci analysis and Mendelian Randomization will be performed to reveal potential causal relationships, and the prothrombotic potential of the proteins will be tested in in vitro experiments.
