| dc.description.abstractEn | BACKGROUND: The thrombin generation assay (TGA) evaluates the potential of plasma to generate thrombin over time, providing a global picture of an individual's hemostatic balance. OBJECTIVES: This study aimed to identify novel biological determinants of thrombin generation using a multi-omics approach. METHODS: Associations between TGA parameters and plasma levels of 377 antibodies targeting 236 candidate proteins for cardiovascular risk were tested using multiple linear regression analysis in 770 individuals with venous thrombosis from the MARTHA study. Proteins associated with at least three TGA parameters were selected for validation in an independent population of 536 healthy individuals (EFS-AM). Proteins with strongest associations in both groups underwent additional genetic analyses and in vitro experiments. RESULTS: Eighteen proteins were associated (p<1.33x10-4) with at least three TGA parameters in MARTHA, among which 13 demonstrated a similar pattern of associations in EFS-AM. Complement proteins C5 and C9 had the strongest associations in both groups. Ex vivo supplementation of platelet-poor plasma with purified C9 protein had a significant dose-dependent effect on TGA parameters. No effect was observed with purified C5. Several single nucleotide polymorphisms associated with C5 and C9 plasma levels were identified, with the strongest association for the C5 missense variant rs17611, which was associated with a decrease in C5 levels, ETP and Peak in MARTHA. No association of this variant with TGA parameters was observed in EFS-AM. CONCLUSIONS: This study identified complement proteins C5 and C9 as potential determinants of thrombin generation. Further studies are warranted to establish causality and elucidate the underlying mechanisms. | |
