Graphical Abstract:


Background: The vessel stenosis and re-stenosis processes are mainly related to cellular and molecular events. The vascular smooth muscle cell (VSMC) activation is the basic element in these lesions. Based on monocyte and macrophage inflammatory responses and also VSMC motility, a complex protein network is dynamically proposed between these cells. The aim of this study was to highlight the protein communications involved in VSMC proliferation and migration signaling pathways.

Methods: A bibliographic search was performed on finding total macrophage, monocyte and VSMC proteomes (n=1262). The proteomes were compartmented on cellular components (Gene Ontology). The primary protein-protein interaction (PPIs) networks were constructed after merging the VSMC proteome with extracellular monocyte and macrophage proteins. The network clusters were determined using STRING server and were evaluated for contributing in KEGG signaling pathways.

Results: The associations between extracellular monocyte (n=71) and macrophage (n=43) proteins and VSMC signaling pathways were evaluated on four PPI networks. Several clusters were observed on each network. The genes were merged in similar clusters and were the subjects for contributing in KEGG signaling pathways.

Conclusion: The cytokine-cytokine receptor interaction, focal adhesion and regulation of actin cytoskeleton pathways were suggested to be involved in VSMC proliferation and migration by extracellular monocyte and macrophage proteins.

Keywords: Atherosclerosis, network, cluster, pathway, VSMC, macrophage, monocyte.
