Effect of CP treatment on gene expression of inflammation markers in HFD induced mouse model after treatment for 9 weeks. The mRNA gene expression of intestine was determined by RT-PCR. The relative gene expression of (A) MCP-1, (B) IL-1β and (C) TNF-α for inflammation were measured in intestine. The relative gene expression of (D) IL-6 was measured in liver. Data shown in mean±standard deviation and evaluated using one-way analysis of variance (#p<0.05, ##p<0.01, ###p<0.001 compared to the Normal group; *p<0.05, **p<0.01, ***p<0.001 compared to the HFD group). NOR: normal diet, HFD: high fat diet, XEN: Xenical, CP: Crataegus pinnatifida, RT-PCR: real-time reverse transcription polymerase chain reaction, MCP-1: monocyte chemoattractant protein-1, IL-1β: Interleukin-1beta, TNF-α: tumor necrosis factor-alpha, IL-6: Interleukin 6.
