Abstract

Long noncoding RNAs (lncRNAs) and microRNAs (miRs) serve critical roles in various cellular processes and can be used as noninvasive biomarkers in human diseases. The present study aimed to investigate the effects of lncRNA plasmacytoma variant translocation 1 (PVT1) and miR‑190a‑5p on vascular endothelial cell (EC) proliferation and assess their clinical value in the diagnosis of chronic heart failure (CHF). The expression of PVT1 and miR‑190a‑5p was investigated using reverse transcription‑quantitative PCR. The interaction between PVT1 and miR‑190a‑5p was confirmed using a luciferase reporter assay. A Cell Counting Kit‑8 assay was performed to examine EC proliferation. A receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of PVT1 and miR‑190a‑5p. PVT1 directly decreased the expression of miR‑190a‑5p in ECs. Overexpression of miR‑190a‑5p in ECs led to inhibited cell proliferation and miR‑190a‑5p antagonized the promotive effect of PVT1 on EC proliferation. Serum expression of PVT1 increased, while serum expression of miR‑190a‑5p decreased in patients with CHF compared with healthy controls (all P<0.001). The ROC curves indicated that PVT1 and miR‑190a‑5p were two diagnostic biomarkers of CHF, and the combination of PVT1 and miR‑190a‑5p showed better diagnostic accuracy compared with using PVT1 or miR‑190‑5p alone. In conclusion, the present study demonstrated that PVT1 promoted EC proliferation by directly suppressing miR‑190a‑5p. Circulating PVT1 and miR‑190a‑5p are possible two candidate diagnostic biomarkers of CHF, and the combined detection of the two indicators may provide a novel approach for CHF diagnosis.
