Liver necrosis in the centrilobular areas developed after carbon tetrachloride treatment, but its histological extent and plasma ALT activities were significantly smaller in the transgenic mice aged 8 weeks than in the wild-type C57BL/6 control mice.

Northern and western blot analyses showed that OPN was increasingly expressed during the progressive activation of cultured rat HSCs, and a significant increase in OPN was observed in carbon tetrachloride-induced rat liver fibrosis.

The delayed healing was associated with a persistent inflammatory reaction, over-production of osteopontin, early and prominent dystrophic calcification, and impaired hepatocyte scattering/migration into diseased areas.

RESULTS: Two thousand seventy-three probe sets were differentially expressed in at least 1 of 3 models of HSC activation, including novel genes that encode proinflammatory and antiapoptotic mediators; transcription factors; cell surface receptors; and cytoskeleton components such as CXCL14, survivin, septin 4, osteopontin, PRX1, LMCD1, GPR91, leiomodin, and anillin.
