We attempted to investigate molecular mechanisms underlying phenotypic change of
vascular smooth muscle cells (VSMCs) by determining signaling molecules involved
in chemokine production. Treatment of human aortic smooth muscle cells (HAoSMCs)
with thrombin resulted not only in elevated transcription of the (C-C motif)
ligand 11 (CCL11) gene but also in enhanced secretion of CCL11 protein.
Co-treatment of HAoSMCs with GF109230X, an inhibitor of protein kinase C, or
GW5074, an inhibitor of Raf-1 kinase, caused inhibition of ERK1/2 phosphorylation
and significantly attenuated expression of CCL11 at transcriptional and protein
levels induced by thrombin. Both Akt phosphorylation and CCL11 expression induced
by thrombin were attenuated in the presence of pertussis toxin (PTX), an
inhibitor of Gi protein-coupled receptor, or LY294002, a PI3K inhibitor. In
addition, thrombin-induced production of CCL11 was significantly attenuated by
pharmacological inhibition of Akt or MEK which phosphorylates ERK1/2. These
results indicate that thrombin is likely to promote expression of CCL11 via
PKC/Raf-1/ERK1/2 and PTX-sensitive protease-activated receptors/PI3K/Akt pathways
in HAoSMCs. We propose that multiple signaling pathways are involved in change of
VSMCs to a secretory phenotype.
