- Abstract
There is increasing evidence that long non-coding (lnc)RNA EGFR-AS1 is involved in the development of numerous types of cancer, including non-small-cell lung cancer (NSCLC). The Cancer Genome Atlas (TCGA) demonstrates that EGFR-AS1 is highly expressed in NSCLC. Downregulation of EGFR-AS1 in A549 and PC9 NSCLC cells demonstrates inhibition of NSCLC proliferation, invasion and metastasis. The present study demonstrated that lncRNA EGFR-AS1 was essential for the development of NSCLC through its function as a competitive endogenous RNA binding to miR-449a and upregulating histone deacetylase 1. In brief, it identified a novel signaling pathway that mediated the invasion and metastasis of NSCLC and may therefore provide a new treatment target for NSCLC.
