Inhibition of Plasminogen Activator Inhibitor 1 Attenuates Hepatic Steatosis but Does Not Prevent Progressive Nonalcoholic Steatohepatitis in Mice.

ABSTRACT: Plasminogen activator inhibitor 1 (PAI-1), an essential regulator of fibrinolysis, is increasingly implicated in the pathogenesis of metabolic disorders, such as obesity and nonalcoholic fatty liver disease (NAFLD). Pharmacologic inhibition of PAI-1 is emerging as a highly promising therapeutic strategy for obesity and its sequelae. Given the well-established profibrotic function of PAI-1, we considered whether PAI-1 may serve as a target for antifibrotic therapy in nonalcoholic steatohepatitis (NASH). We therefore determined the effect of genetic Pai-1 deletion and pharmacologic PAI-1 inhibition on the development of NASH-related fibrosis in mice. Pai-1 knockout (Pai-1 -/-) and wild-type control (Pai-1 +/+) mice were fed a high-fat/high-cholesterol high-sugar (HFHS) diet or a methionine-
