High and long‐term von Willebrand factor expression after Sleeping Beauty transposon‐mediated gene therapy in a mouse model of severe von Willebrand disease

Essentials von Willebrand disease (VWD) is the most common inherited bleeding disorder. Gene therapy for VWD offers long-term therapy for VWD patients. Transposons efficiently integrate the large von Willebrand factor (VWF) cDNA in mice. Liver-directed transposons support sustained VWF expression with suboptimal multimerization.Background Type 3 von Willebrand disease (VWD) is characterized by complete absence of von Willebrand factor (VWF)....
