Summary: Cardiac fibrosis is a major type of adverse remodeling, predisposing the disease progression to ultimate heart failure. However, the complexity of pathogenesis has hampered the development of therapies. One of the key mechanisms of cardiac diseases has recently been identified as long non-coding RNA (lncRNA) dysregulation. Through in vitro and in vivo studies, we identified an lncRNA NONMMUT067673.2, which is named as a cardiac fibrosis related lncRNA (CFRL). CFRL was significantly increased in both mouse model and cell model of cardiac fibrosis. In vitro, CFRL was proved to promote the proliferation and migration of cardiac fibroblasts by competitively binding miR-3113-5p and miR-3473d and indirectly up-regulating both CTGF and FN1. In vivo, silencing CFRL significantly mitigated cardiac fibrosis and improved left ventricular function. In short, CFRL may exert an essential role in cardiac fibrosis and interfering with CFRL might be considered as a multitarget strategy for cardiac fibrosis and heart failure.
