From: Disruption of the kringle 1 domain of prothrombin leads to late onset mortality in zebrafish

Direct oral anticoagulants prevent occlusive thrombus formation in zebrafish. 5 dpf larvae were exposed to chemical inhibitors of thrombin (dabigatran) and FXa (apixaban, rivaroxaban) for 24 hours. This resulted in the inability to form occlusive venous thrombi at 6 dpf in wild-type larvae following laser-mediated endothelial injury.
