TNFAIP6 and Venous thrombosis: The association of ANXA3, TNFAIP6, TXK, BACH2, and SERPINB2 mRNA expression with the type of thrombosis (arterial or venous) in t-PAPS is shown in Figure 4, Panel A. ANXA3 mRNA upregulation was more evident in arterial thrombosis than in venous thrombosis when compared with controls.
