SERPINB2 and Venous thrombosis: Next, the association of ANXA3, TNFAIP6, TXK, BACH2, and SERPINB2 mRNA expression with the number of previous thrombosis events (single or multiple thrombosis) is shown in Figure 4, Panel B. ANXA3 mRNA upregulation was, again, more pronounced in multiple thrombosis than in single thrombosis when compared to controls.
