Blood was collected from the IVC, and the livers were recovered. Serum alanine transaminase (ALT) was measured using analytical kits from Pointe Scientific (Uncoln Park, MI) [8 (link)]. Histology was performed using hematoxylin-eosin (H&E) staining. Necrotic areas were quantified in a blinded manner by image analysis of 10 randomly selected fields per liver in slides stained with H&E using a IPlab 3.7v software (BD Biosciences, Rockville, MD) [9 (link)]. Apoptosis was assessed by terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) using an In Situ Cell Death Detection Kit [10 (link)]. RT-PCR was used to determine the expression of transforming growth factor-β (TGF-β) mRNA.
