Abstract
The great saphenous vein is the most commonly used vessel for coronary artery bypass grafting (CABG), but its use has been associated with a high restenosis rate at 10-year follow-up. This study sought to determine the key genes associated with vein graft restenosis that could serve as novel therapeutic targets. A total of 3075 upregulated and 1404 downregulated genes were identified after transcriptome sequencing of three pairs of restenosed vein grafts and intraoperative spare great saphenous veins. Weighted gene co-expression network analysis showed that the floralwhite module had the highest correlation with vein graft restenosis. The intersection of the floralwhite module gene set and the upregulated gene set contained 615 upregulated genes strongly correlated with vein graft restenosis. Protein-protein interaction network analysis identified six hub genes (ITGAM, PTPRC, TLR4, TYROBP, ITGB2 and CD4), which were obtained using the STRING database and CytoHubba. Gene Ontology term and Kyoto Encyclopedia of Genes and Genomes pathway enrichment analyses showed that the common hub genes were mainly involved in the composition of the cell membrane; in biological processes such as neutrophil degranulation, receptor binding and intercellular adhesion, innate immune deficiency; and other signaling pathways. Finally, ITGB2 was selected as the target gene, and its expression was verified in tissues. The results showed that ITGB2 was significantly overexpressed in occluded vein grafts. To study the function of ITGB2 in HVSMCs, primary HVSMCs were cultured and successfully identified. EdU incorporation, wound healing and transwell assays showed that ITGB2 silencing significantly inhibited the proliferation and migration of HVSMCs stimulated by PDGF-BB. Overall, our study provides a basis for future studies on preventing restenosis following CABG.

Abstract
Background Vein graft restenosis (VGR), which appears to be caused by dyslipidemia
following vascular transplantation, seriously affects the prognosis and
long-term quality of life of patients. Methods This study analyzed the genetic data of restenosis (VGR group) and
non-stenosis (control group) vessels from patients with coronary heart
disease post-vascular transplantation and identified hub genes that might be
responsible for its occurrence. GSE110398 was downloaded from the Gene
Expression Omnibus database. A repeatability test for the GSE110398 dataset
was performed using R language. This included the identification of
differentially expressed genes (DEGs), enrichment analysis via Metascape
software, pathway enrichment analysis, and construction of a protein–protein
interaction network and a hub gene network. Results Twenty-four DEGs were identified between VGR and control groups. The four
most important hub genes (KIR6.1, PCLP1,
EDNRB, and BPI) were identified, and
Pearson’s correlation coefficient showed that KIR6.1 and
BPI were significantly correlated with VGR.
KIR6.1 could also sensitively predict VGR
(0.9 < area under the curve ≤1). Conclusion BPI and KIR6.1 were differentially
expressed in vessels with and without stenosis after vascular
transplantation, suggesting that these genes or their encoded proteins may
be involved in the occurrence of VGR.
