Liver fibrosis was induced in BALB/C mice with carbon-tetrachloride (CCl4) for 8 weeks with either vitamin D [100 ng/kg] or InVivoMAb anti-mouse OPN [100 μg/kg] 2X/week started at week-4 of CCl4. The liver injury profile of serum ALT, AST, and inflammatory cytokines were evaluated. This evidence concerns the gene GPT and Hepatic fibrosis.
