Akt is involved in HIMF-induced IL-18 production. (A) Cells were incubated with HIMF (3 nM) for indicated time intervals and cell lysates were immunoblotted with an antibody specific for phospho-Akt. (B) Cells were transfected with Akt siRNA for 24 h, and Akt protein expression was analyzed. (C) HIMF-induced IL-18 mRNA was inhibited by the Akt inhibitor or Akt siRNA. (D) Cells were pretreated for 30 min with the Akt inhibitor or transfected with Akt siRNA for 24 h, then stimulated with HIMF for 24 h, and the conditioned media was collected and examined by ELISA. (E) HIMF-induced Akt phosphorylation was inhibited by an Akt inhibitor or Akt siRNA. (F) Cells were treated with the PDK1 inhibitor or LY294002 for 30 min then stimulated with HIMF for 120 min, and phospho-Akt protein expression was analyzed. Results are expressed as the means ± SEM of four independent experiments. *p < 0.05 as compared with the control group. #p < 0.05 as compared with HIMF-treated group.
