    ( A ) Relative IL-8 mRNA expression in M2 macrophages treated with leptin with or without the inhibitors. M2 macrophages were pretreated with JAK inhibitor AG490 (50 μmol/L), PI3K inhibitor LY294002 (10 μmol/L), ERK inhibitor PD980590 (10 μmol/L), p38 MAPK inhibitor SB203580 (20 μmol/L), or JNK inhibitor SP600125 (50 μmol/L) for 1 hour and then were treated with PBS or leptin (100 ng/mL). Relative IL-8 mRNA levels were analyzed by qRT-PCR. ***represents significant difference between the indicated groups versus the PBS group, P < 0.001. **represents significant difference between the indicated groups versus the Leptin + DMSO group, P < 0.01. ( B ) A representative image of Western blot for IL-8 protein expression in M2 macrophages treated in the same manner as (A).
