(A) Cilostazol-mediated activation of AMPK in rat VSMC. VSMC were treated with colostazol (100μM) for the indicated time periods before lysis, after which samples of cell lysate were probed with antibodies specific for the phosphorylated forms of AMPK and acetyl-CoA carboxylase (ACC). (B) HUVEC treated with cilostazol (100 μM) alone or in the presence of an adenylate cyclase inhibitor SQ22536 (10 μM) or a cell-permeable cAMP analog pCTP-cAMP (100 μM). After 15 min of incubation, the cells were lysed and p-AMPK activity was analyzed. Three independent studies showed similar results.

(A) Human umbilical vein endothelial cells (HUVEC) were incubated with tumour necrosis factor alpha (TNFα) for 0–180 min. The cells were lysed and subjected to western blot analysis using anti-IκB-α and anti-phospho-IκB-α antibodies. (B) The effect of cilostazol on IκB-α degradation in HUVEC. Cells were incubated for 30 min with cilostazol (30 and 100 μM), followed by TNFα for 30 min. Cells were then lysed and subjected to western blot analysis using anti-IκBα antibody. (C) The effect of cilostazol on IKK activity in HUVEC. Cells were incubated for 30 min with cilostazol (30 and 100 μM), followed by TNFα for 15 min. Cells were then lysed and immunoprecipitated with anti-IKKα/β antibody and used for kinase assay using recombinant IκBα as a substrate. Note that equal band densities for IKKα/β and GST-IκBα were observed. Three independent studies showed similar results.

(B) The effect of fenofibrate on IκB-α degradation in HUVEC. Cells were incubated for 30 min with fenofibrate (30 and 100 μM), followed by TNFα for 30 min.

Cells were incubated for 30 min with metformin (30 and 100 μM), followed by TNFα for 15 min. Cells were then lysed and immunoprecipitated with anti-IKKα/β antibody and used for kinase assay using recombinant IκB-α as a substrate. Note that equal band densities for IKKα/β- and IκB-α were observed. Three independent experiments for (A) and (B) and two independent experiments for (C) were performed. Similar results were obtained in each experiment and representative photos were shown.

(A) Effect of NOR3 and SIN-1 on degradation and phosphorylation of I B-α in rat VSMC. Cells were incubated for 45 min with various concentrations of NOR3 (1 mM) or SIN-1 (1 mM), followed by LPS (30 μg/ml) for 0–180 min. Cell were lysed and subjected to Western blot analysis using anti-I B-α antibody and anti-phospho-I B-α. (B) Effect of NOR3 and SIN-1 on IKK activity in rat VSMC. Cells were incubated for 45 min with various concentrations of NOR3 (0.25–1 mM) or SIN-1 (1 mM), followed by LPS (30 μg/ml) for 15 min.
