Research Article


The prognosis of colorectal cancer (CRC) is still very poor, owing to the high incidence of metastasis. Long noncoding RNA TCF7 (lncTCF7) has been shown to play critical roles in human CRC development and progression, but the molecular mechanisms of lncTCF7 in CRC are still unknown. This study aimed to explore the functions and molecular mechanisms of lncTCF7 on the migration and invasion of CRC cells. Notably, lncTCF7 was highly expressed in CRC cell lines relative to normal colonic epithelial cells. LncTCF7 knockdown significantly inhibited migration and invasion of CRC cells. In addition, TCF7 was highly expressed in CRC cell lines relative to that in normal colonic epithelial cells and its expression was significantly decreased in CRC cells transfected with si-lncTCF7. RNA immunoprecipitation, chromatin immunoprecipitation, and luciferase reporter assays showed that LncTCF7 recruits BAF170 to activate the TCF7 promoter and regulate TCF7 expression. TCF7 overexpression could promote migration and invasion in CRC cells transfected with si-lncTCF7, which reversed the effect of lncTCF7 on the migration and invasion of CRC cells. In conclusion, our data indicate that the downregulation of lncTCF7 significantly inhibits migration and invasion of CRC cells by inhibiting TCF7 expression, suggesting that lncTCF7 may be a potential target for CRC therapy.
