Abstract:
:microRNAs (miRNAs) are noncoding RNAs that regulates the expression of target messenger RNAs (mRNAs). c-FLIP is an inhibitor of cell apoptosis through inhibition of caspase 8. miR-150, miR-504, and miR-519d were related to cancer cell proliferation, invasion, and migration in colorectal cancer (CRC). However, the role of miR-150-504-519d in CRC has not been studied and the relationship between miR-150-504-519d and c-FLIP remains unclear. In this study, we found that c-FLIP was upregulated in CRC tissues, without detectable expression in normal CRC tissues. Using SW48 cell line, we further showed that miR-150-504-519d inhibited migration, invasion, and promoted apoptosis of SW48 cells. Moreover, in SW48 cell line transfected with miR-150-504-519d, the protein expression of c-FLIP was significantly lower compared with cells transfected with scramble. Our results demonstrated upregulation of c-FLIP in CRC, which was downregulated in SW48 cells after the transfection of miR-150-504-519d, suggesting that manipulation of miR-150-504-519d expression might be a novel approach for the treatment of colorectal cancer.
