HO-1 and CO decrease platelet-derived growth factor-induced vascular smooth muscle cell migration via inhibition of Nox1.

OBJECTIVE Heme oxygenase-1 (HO-1), via its enzymatic degradation products, exhibits cell and tissue protective effects in models of vascular injury and disease. The migration of vascular smooth muscle cells (VSMC) from the medial to the intimal layer of blood vessels plays an integral role in the development of a neointima in these models. Despite this, there are no studies addressing the effec...

Rosuvastatin suppresses platelet-derived growth factor-BB-induced vascular smooth muscle cell proliferation and migration via the MAPK signaling pathway

An imbalance in the proliferation and migration of vascular smooth muscle cells (VSMCs) is significant in the onset and progression of vascular diseases, including arteriosclerosis and restenosis subsequent to vein grafting or coronary intervention. Rosuvastatin, a selective inhibitor of hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase, has pharmacological properties including the ability t...

Artemisinin attenuates platelet-derived growth factor BB-induced migration of vascular smooth muscle cells

BACKGROUND/OBJECTIVES Artemisinin (AT), an active compound in Arternisia annua, is well known as an anti-malaria drug. It is also known to have several effects including anti-oxidant, anti-inflammation, and anti-cancer activities. To date, the effect of AT on vascular disorders has not been studied. In this study, we investigated the effects of AT on the migration and proliferation of vascular ...

Apolipoprotein D and platelet-derived growth factor-BB synergism mediates vascular smooth muscle cell migration.

We identified apolipoprotein (apo)D in a search for proteins upregulated in a posttranscriptional manner similar to fibronectin in motile smooth muscle cells (SMCs). To address the function of apoD in SMCs, we cloned a partial apoD cDNA from ovine aortic (Ao) SMCs using RT-PCR. We documented a 2.5-fold increase in apoD protein but no increase in apoD mRNA in Ao SMCs 48 hours after a multiwound ...

Nox1 mediates basic fibroblast growth factor-induced migration of vascular smooth muscle cells.

OBJECTIVE Basic fibroblast growth factor (bFGF) stimulates vascular smooth muscle cell (SMC) migration. We determined whether bFGF increases SMC reactive oxygen-species (ROS) and studied the role of ROS for SMC migration. METHODS AND RESULTS bFGF rapidly increased rat SMC ROS formation and migration through pathways sensitive to inhibition of NADPH oxidases, PI3-kinase, protein kinase C, and ...
