Regulating dietary fat absorption may impact progression of nonalcoholic fatty liver disease (NAFLD). Here we asked if inducible inhibition of chylomicron assembly, as observed in intestine-specific microsomal triglyceride transfer protein knockout mice (Mttp-IKO), could retard NAFLD progression and/or reverse established fibrosis in two dietary models. Mttp-IKO mice fed a methionine/choline deficient (MCD) diet exhibited reduced hepatic triglycerides (TG), inflammation and fibrosis, associated with reduced oxidative stress and downstream activation of JNK and NFκB signaling pathways. However, when Mtt
