Carbon tetrachloride does not promote hepatic fibrosis in ob/ob mice via downregulation of lipocalin-2 protein.

ABSTRACT: Although leptin-deficient ob/ob mice have been investigated to determine whether hepatic steatosis promotes susceptibility to hepatotoxic insults, carbon tetrachloride (CCl₄)-induced hepatic fibrosis in ob/ob mice remains largely unknown. In this study, we evaluate the pathogenic mechanisms of hepatic fibrosis in CCl₄-treated wild-type (WT) and ob/ob mice and analyze some parameters related to lipogenesis, inflammation, fibrosis, oxidative stress, apoptosis, and autophagy. CCl₄ treatment attenuated liver weight and lipogenesis in ob/ob mice. Increased hepatic fibrosis-related proteins were reduced in CCl₄-treated ob/ob mice compared with CCl₄-treated WT mice. Specifically, the expression of lipocalin-2 (LCN2) was markedly reduced in CC
