Function and regulation of miR-186-5p, miR-125b-5p and miR-1260a in chordoma
BMC cancer(2023)
Abstract
Background The function and regulation of miRNAs in progression of chordoma were unclear. Methods Five miRNAs were identified by the machine learning method from the miRNA expression array. CCk-8 assay, EDU assay, wound healing migration assay, and trans-well assay were used to reveal the effect of the miRNAs in chordoma cell lines. Moreover, bioinformation analysis and the mRNA expression array between the primary chordomas and recurrent chordomas were used to find the target protein genes of miRNAs. Furthermore, qRT-PCR and luciferase reporter assay were used to verify the result. Results miR-186-5p, miR-30c-5p, miR-151b, and miR-125b-5p could inhibit proliferation, migration, and invasion of chordoma while miR-1260a enhances proliferation, migration, and invasion of chordoma. Recurrent chordoma has a worse disease-free outcome than the primary chordoma patients. AMOT, NPTX1, RYR3, and P2RX5 were the target protein mRNAs of miR-186-5p; NPTX1 was the target protein mRNAs of miR-125b-5p; and AMOT and TNFSF14 were the target protein mRNAs of miR-1260a. Conclusions miR-186-5p, miR-125b-5p, miR-1260a, and their target protein mRNAs including AMOT, NPTX1, RYR3, P2RX5, TNFSF14 may be the basement of chordoma research.
