Long non-coding RNA FEZF1-AS1 facilitates cell proliferation and migration in colorectal carcinoma.

ABSTRACT: Long non-coding RNAs (lncRNA) have been shown to play important roles in the development and progression of cancer. Here, we discovered a novel long noncoding RNA (lncRNA) FEZF1 antisense RNA1 (FEZF1-AS1) is markedly upregulated in human primary colorectal carcinoma (CRC) and associated with CRC metastasis and poor prognosis. Moreover, the downregulation of FEZF1-AS1 expression significantly inhibited the CRC cells proliferation, migration and invasiveness, suppressed S-phase entry in vitro, and repressed tumor growth and metastasis in vivo. In contrast, overexpression of FEZF1-AS1 could promote the aggressive behaviors of CRC cells. We further discovered that the downregulation of FEZF1-AS1 reduced its sense-cognate gene FEZF1 mRNA and protein expression in CRC cells. There was a positive
