Plasminogen activator inhibitor‐1 augments damage by impairing fibrinolysis after traumatic brain injury
2019
Objective Plasminogen activator inhibitor-1 (PAI-1) is the key endogenous inhibitor of fibrinolysis, and enhances clot formation after injury. In traumatic brain injury, dysregulation of fibrinolysis may lead to sustained microthrombosis and accelerated lesion expansion. In the present study, we hypothesized that PAI-1 mediates post-traumatic malfunction of coagulation, with inhibition or genetic depletion of PAI-1 attenuating clot formation and lesion expansion after brain trauma. Methods We evaluated PAI-1 as a possible new target in a mouse controlled cortical impact (CCI) model of traumatic brain injury. We performed the pharmacological inhibition of PAI-1 with PAI-039 and stimulation b…
Evaluation of PAI-1 in endometriosis using a homologous immunocompetent mouse model
2018
To analyze the role of PAI-1 (plasminogen activator inhibitor 1) in endometriotic lesion growth, we studied the effect of PAI-1 inhibition by PAI-039 using a homologous mouse model of endometriosis that allows noninvasive monitoring. Endometrial tissue from donor mice was collected, labeled with mCherry adenovirus, and implanted into a subcutaneous pocket on the ventral abdomen of recipient mice. Seven days after transplantation, mice were randomly allocated in two groups and treated once daily for 2 weeks with either vehicle (control group) or PAI-1 inhibitor (PAI-039 group). Endometriotic lesion size generated in recipient mice was monitored by mCherry signal. Animals were euthanized 21 d…
