After feeding, β-cryptoxanthin attenuated fat accumulation, increases in Kupffer and activated stellate cells, and fibrosis in CL diet-induced NASH in the mice. Comprehensive gene expression analysis showed that although β-cryptoxanthin histochemically reduced steatosis, it was more effective in inhibiting inflammatory gene expression change in NASH. β-Cryptoxanthin reduced the alteration of expression of genes associated with cell death, inflammatory responses, infiltration and activation of macrophages and other leukocytes, quantity of T cells, and free radical scavenging. However, it showed little effect on the expression of genes related to cholesterol and other lipid metabolism. The expression of markers of M1 and M2 macrophages, T helper cells, and cytotoxic T cells was significantly induced in NASH and reduced by β-cryptoxanthin. β-Cryptoxanthin suppressed the expression of lipopolysaccharide (LPS)-inducible and/or TNFα-inducible genes and the antioxidant enzyme glutathione peroxidase 1 in NASH. Thus, β-cryptoxanthin suppresses inflammation and the resulting fibrosis probably by primarily suppressing the increase and activation of macrophages and other immune cells. Reducing oxidative stress is likely to be a major mechanism of inflammation and injury suppression in the livers of mice with NASH. Eight-week old male C57BL/6J mice were fed for 12 weeks on a CRF-1 standard chow (control), a high-cholesterol and high-fat diet (CL diet; 38.23% CRF-1, 60% cocoa butter, 1.25% cholesterol, 0.5% sodium cholate) or a CL diet containing 0.003% β-cryptoxanthin.E-GEOD-51432http://www.ebi.ac.uk/arrayexpress/experiments/E-GEOD-51432/samples/
