Abstract

Long non‑coding RNAs (lncRNAs) are recently identified regulators in tumorigenesis and tumour progression. BRAF‑activated lncRNA (BANCR) is overexpressed in melanoma and has a potential functional role in melanoma cell migration. However, little is known concerning the role of BANCR in the development of colorectal cancer (CRC). The current study examined BANCR expression in 60 pairs of CRC and matched adjacent normal tissues. The quantitative polymerase chain reaction results showed that BANCR was frequently overexpressed in cancer tissues and this overexpression was found to significantly correlate with lymph node metastasis and tumour stage. The ectopic expression of BANCR contributed to the migration of human CRC Caco‑2 cells, whereas knockdown of BANCR inhibited the migration of the HCT116 cells in vitro. Further investigation into the underlying mechanisms responsible for the migratory effects revealed that BANCR induced the epithelial‑mesenchymal transition (EMT) through an MEK/extracellular signal‑regulated kinase‑dependent mechanism as treatment with the MEK inhibitor, U0126 decreased migration and reversed the EMT in the BANCR‑overexpressed HCT116 cells. These results revealed the significance of BANCR in the molecular etiology of CRC and implied the potential application of BANCR in the therapeutic treatment of CRC.
