Abstract Background: Plasmacytoma variant translocation 1 (PVT1) is a newly discovered long non-coding RNA (lncRNA), and it has not been previously studied in the inflammatory responses of peripheral blood mononuclear cells (PBMCs) of patients with coronary artery disease (CAD). Methods: This cross-sectional study was conducted in 15 CAD patients and 15 non-CAD (NCAD) individuals. PVT1 expression in PBMCs of the participants was measured, using real-time PCR. Interleukin (IL)-10, IL-22 and MMP-9 in the plasma and supernatant of the cultured PBMCs in the presence or absence of lipopolysaccharide (LPS) was assessed, using flowcytometry and ELISA.Results: An increased expression of PVT1 was observed in untreated PBMCs of CAD patients compared to the NCAD group. There was a significant up-regulation of PVT1 after LPS treatment in PBMCs of both groups. Plasma matrix metalloproteinase-9 (MMP-9) levels were found to be higher in CAD patients compared to the controls. The level of IL-10 and IL-22 production from the non-treated PBMCs of CAD was significantly lower compared to the NCAD group. In the total examined population, PVT1 expression was negatively correlated with IL-10 secretion. The results also showed a significant negative correlation between PVT1 expression and IL-10 produced by untreated cells. Conclusions: PVT1 expression is increased in PBMCs of CAD patients and this increased expression could be associated with decreased IL-10 production from PBMCs of these patients.

Objective: Circular RNAs (circRNAs) function as promising biomarkers and therapeutic targets for coronary artery disease due to their high stability, covalently closed structure and potential gene regulation. We aimed to identify the expression profile and role of circular RNAs (circRNAs) in coronary artery disease (CAD). Methods: We performed RNA sequence analysis of circRNAs in peripheral blood mononuclear cells of 5 CAD patients and 5 controls. Bioinformatics analyses was adopted to explore biological functions of differentially expressed circRNAs. The miRanda and TargetScan tools were used to predict the miRNA targeting interactions and to construct a triple network of differentially expressed gene-circRNA-miRNA-mRNA. Results: In total, 13160 downregulated and 12905 upregulated circRNAs were identified in CAD. A gene ontology annotation analysis showed that genes in the network were involved in organelle organization, cell cycle, mitotic cycle and cellular metabolic process. Parental genes of the 10 dysregulated-circRNAs were involved in metabolism and protein modification, and these circRNAs might regulate gene expression associated with CAD via miRNA sponges. Conclusion: As potential ceRNAs, dysregulated circRNAs may be involved in the pathogenesis of CAD, which provides new insights into diagnosis and prognosis of coronary artery disease.
