Long noncoding RNA-dependent regulation of vascular smooth muscle cell proliferation and migration in hypertension.

Hypertension is one of the main risks causing cardiovascular diseases. Long noncoding RNAs (lncRNAs) play a critical role in many physiological and pathological conditions. However, their role in hypertension is still unclear. In this study, 460 lncRNAs and 522 mRNA were identified to have different expressions in the thoracic aortas of spontaneously hypertensive rats compared with normotensive Wistar-Kyoto rats through next-generation sequencing. Several randomly selected lncRNAs including NONRATT011842 were validated by qRT-PCR and their potential functions were predicted by co-expression analysis with the help of bioinformatics. Moreover, this study focused on the function of lncRNA NONRATT011842 in the vascular smooth muscle cells (VSMCs) during hypertension and confirmed that NONRATT011842 could interact with PABPC1 to regulate the functions of VSMCs. Therefore, the intervention or utilization of certain lncRNAs could be a new biomarker for the diagnosis and prevention of hypertension.
