Effect of TFRG on Arg-1 expression at gene and protein level in IL-4/IL-13-induced murine RAW264.7 cells. (a) Effect of TFRG on Arg-1 mRNA in IL-4/IL-13-induced murine RAW264.7 cells. RAW264.7 macrophages were incubated with pretreatment of 25 and 50μg/mL TFRG and stimulated with IL-4 (20ng/mL)/IL-13 (20ng/mL) for 24h. Values are presented as the mean ± standard deviation from three replicates. ^##P < 0.01 versus C group; < 0.01 versus M2 group. (b) Effect of TFRG on Arg-1 protein in IL-4/IL-13-induced murine RAW264.7 cells. RAW264.7 macrophages were incubated with pretreatment of 25 and 50μg/mL TFRG and stimulated with IL-4 (20ng/mL)/IL-13 (20ng/mL) for 24h. Values are presented as the mean ± standard deviation from three replicates. ^##P < 0.01 versus C group; < 0.01 versus M2 group.
