A novel long noncoding RNA IRAIN regulates cell proliferation in non small cell lung cancer

Int J Clin Exp Pathol. 2015 Oct 1;8(10):12268-75. eCollection 2015.

Abstract

Long non-coding RNAs (lncRNAs) are a novel class of RNA molecules defined as transcripts longer than 200 nucleotides that lack protein coding potential. LncRNA IRAIN has been verified that it is related to acute myeloid leukemia (AML) and breast cancer. However, there was no study to clarify whether it is involved in non-small cell lung cancer (NSCLC). Here, we demonstrated IRAIN as a tumor promoter in NSCLC. Its expression level was remarkably upregulated in NSCLC tissues and connected with tumor size and smoking status. Knockdown of IRAIN suppressed NSCLC cells proliferation in vitro. These data identify IRAIN as a novel promoting gene, which plays a vital role in tumorigenesis of NSCLC.
