OBJECTIVE: To investigate the regulatory effect of long non-coding ribonucleic acid (lncRNA) FER1L4 on biological behaviors of esophageal squamous cell carcinoma (ESCC) cells, such as proliferation and invasion.

PATIENTS AND METHODS: The expressions of FER1L4 were detected in 42 pairs of ESCC tissues and corresponding para-carcinoma tissues and 5 kinds of ESCC cell lines via quantitative reverse transcription-polymerase chain reaction (qRT-PCR). Polyethyleneimine (PEI) and liposomes were used for FER1L4 expression or interference elimination assays, respectively. The proliferation and invasion of ESCC cells were detected via MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide), apoptosis assay, cell cycle assay, and transwell chamber.

RESULTS: Results of qRT-PCR showed that, compared with that in normal tissues, FER1L4 was lowly expressed in ESCC tissues. Overexpression of FER1L4 could inhibit cell proliferation and invasion, promote apoptosis and increase the cell cycle distribution in G0/G1 phase. Knockout of FER1L4 could promote the proliferation and invasion of ESCC cells, inhibit apoptosis and decrease the cell cycle distribution in G0/G1 phase.

CONCLUSIONS: FER1L4 is involved in the occurrence and development of ESCC and plays a key role as a tumor suppressor gene in ESCC.
