Background & Aims: Heme oxygenase-1 (HO-1), an antioxidant defense enzyme, has been shown to protect against oxidant-induced tissue injury. We investigated the role of HO-1 in nutritional steatohepatitis in vitro and in vivo. Methods: AML-12 hepatocytes were cultured in methionine- and choline-deficient (MCD) medium. Cells were transfected with an adenovirus vector that expressed HO-1 (Ad-HO-1) or incubated with the HO-1 inducer hemin or the HO-1 inhibitor stannic mesoporphyrin for 24 hours....[Show more]
