Impacts of pectin oligosaccharide (POS) got from hawthorn fruitage on adiponectin signaling pathway and white adipose metabolism in mice fed with high-fat control. The results showed that POS significantly inhibited the levels of inflammatory cytokines TNF-α and IL-6, and down-regulated expression of CD68. POS dramatically reduced gene expression contents of fatty acid composite concerning enzymes ACC and FAS, as well as TG synthesis-related enzymes SCD-1 and DGAT1 as compared to a high-fat group (HFC). POS dramatically increased expression levels of oxidation-related enzymes of fatty acid ACO, CPT-1, and TG deposition-related enzymes ATGL and HSL as contrast to the high-fat control group. In addition, POS activated adiponectin-mediated AdipoR1/AMPK/PPARα signaling path by upregulating expression levels of AdipoR1, AMPK and PPARα. The results demonstrated that POS can improve lipid metabolism of adipose tissue, and contribute to the creation of functional foods to prevent and treat lipid metabolism disorders.
