Abstract
AIM: To investigate the effect of miR-451-mediated regulation of macrophage migration inhibitory factor (MIF) expression on cell proliferation in human colon carcinoma cell line LoVo.
METHODS: A lentiviral vector overexpressing hsa-mir-451a was designed and used to infect LoVo cells. Real-time quantitative PCR and Western blot were utilized to detect the expression levels of MIF mRNA and protein in LoVo cells and fetal colon cells. Cell proliferation was determined by MTT assay after infection.
RESULTS: The expression of MIF mRNA and protein decreased significantly and cell proliferation was significantly inhibited in LoVo cells infected with the lentiviral vector overexpressing hsa-mir-451a compared to non-infected LoVo cells and fetal colon cells.
CONCLUSION: MIF is a potential target gene of miR-451. Overexpression of miR-451 could suppress LoVo cell proliferation by down-regulating MIF expression.
