Figure 6.
Effect of LMWCs on activator protein-1 (AP-1) in RAW264.7 macrophages. Each cell population (1 × 106 cells/mL) was treated with LMWCs (3 kDa and 50 kDa) at the indicated concentrations of 40 μg/mL for 24 h, respectively (1: Control; 2: 50 kDa chitosan; 3: 3 kDa chitosan; 4: LPS). The figures shown are representative of three independent experiments. These represent mean values of three independent experiments. Values are presented as means ± SD (n = 3). Bars with different letters (a, b, c, d) are statistically different (p < 0.05).
