The positive feedback loop FOXO3/CASC11/miR-498 promotes the tumorigenesis of non-small cell lung cancer.

An increasing number of studies have indicated that long noncoding RNAs (lncRNAs) are involved in the regulation of non-small-cell lung cancer (NSCLC). Nevertheless, there are still numerous undiscovered mechanisms underlying this molecular regulation. Here, the results illustrated that CASC11 is overexpressed in NSCLC tumor tissues and cell lines, which is closely related to the clinical features of NSCLC and poor survival.
