Fig 5. Lunasin inhibited pro-inflammatory adipokine production in 3T3-L1 adipocytes.
3T3-L1 adipocytes were treated with various doses of lunasin and were stimulated with 10 ng/mL TNF-α, 50% RAW-CM, or 1 μg/mL LPS to induce inflammatory conditions for 24 h. A. MCP-1 production was analyzed in the supernatant by ELISA. B. PAI-1 production was analyzed by ELISA. C. Leptin production was analyzed by ELISA. D. Adiponectin production was analyzed by ELISA. Data are presented as mean ± SEM from three independent experiments. Statistical analysis was based on one-way ANOVA and LSD post hoc test; * p < 0.05, or # p < 0.001 vs. control group. LPS, lipopolysaccharide; MCP-1, monocyte chemoattractant protein-1; lun, lunasin; IL, interleukin; PAI-1, plasminogen activator inhibitor-1; RAW-CM, RAW264.7 cell-conditioned medium; TNF-α, tumor necrosis factor-α.
