Purpose: Our research aimed to illuminate the role of miR-100-5p in chordoma and potential mechanism.
Materials and Methods: We used microRNA array analysis to explore differentially expressed miRNAs in chordoma tissue and then verified by qRT-PCR. Cell proliferation and transwell assay were used to evaluate the function of miR-100-5p. Cell apoptosis was analyzed by flow cytometry, and using biological software, we predicted that the insulin-like growth factor 1 receptor (IGF1R) could be the target gene of miR-100-5p, which was then validated by dual luciferase assays and Western blot.
Results: miR-100-5p was downregulated in chordoma tissues. Overexpression of miR-100-5p could suppress the growth of chordoma both in vitro and in vivo, and miR-100-5p could inhibit the migration and invasion of chordoma cells partially by suppressing epithelial–mesenchymal transition (EMT). Furthermore, IGF1R was validated as the target gene of miR-100-5p and expressed in most chordoma tissues.
Conclusion: In conclusion, our results showed that miR-100-5p was lowly expressed in chordoma and inhibited tumor malignant progression by targeting IGF1R.
