Conclusion
LncRNA CASC11 is downregulated in CAD and inhibits TGF-β1.
Methods
This case–control study enrolled patients with CAD and age- and sex-matched healthy control subjects. The plasma levels of lncRNA CASC11 and transforming growth factor-beta 1 (TGF-β1) were measured. Diagnostic values of lncRNA CASC11 and TGF-β1 for CAD were determined using receiver operating characteristic curve analysis. Correlations between plasma levels of lncRNA CASC11 and TGF-β1 were analysed using linear regression.
Objective
To investigate the involvement of long non-coding RNA (lncRNA) Cancer Susceptibility 11 (CASC11) in patients with coronary artery disease (CAD).
Results
The study enrolled 82 patients with CAD and 82 healthy controls. Plasma levels of lncRNA CASC11 were downregulated in patients with CAD, while plasma TGF-β1 levels were upregulated in patients with CAD, compared with healthy controls. Plasma levels of lncRNA CASC11 and TGF-β1 distinguished patients with CAD from healthy controls and were inversely correlated in both groups. LncRNA CASC11 over-expression mediated the downregulation of TGF-β1 in human primary coronary artery endothelial cells, while TGF-β1 over-expression showed no significant effects on lncRNA CASC11 levels. An 8-year follow-up study showed that low lncRNA CASC11 levels were closely correlated with a higher mortality rate in patients with CAD.
