miR-584-5p is a critical regulator in the progression of multiple cancers. However, its specific role and downstream targets in osteosarcoma are unclear. This research investigated the roles and underlying mechanisms of miR-769-5p and the Hippo pathway in osteosarcoma cells.
Materials and Methods:
RT-qPCR, CCK-8 and EdU and colony formation, wound-healing and transwell chamber, flow cytometry, and Western blot assay detected the expression of miR-584-5p and CTGF, cell proliferation, migration, invasion apoptosis and protein expression.
Result:
Their study illuminated that miR-584-5p overexpression repressed osteosarcoma cell migration/invasion and proliferation and facilitated apoptosis. Mechanistically, miR-584-5p targets negatively regulated connective tissue growth factor (CTGF). miR-584-5p inhibited osteosarcoma cell metastasis by regulating CTGF. In addition, miR-584-5p inactivated the Hippo pathway through CTGF in osteosarcoma.
Conclusion:
miR-584-5p inhibits osteosarcoma cell proliferation, migration, and invasion and promotes apoptosis by targeting CTGF, indicating that miR-584-5p acts as a promising diagnostic and predictive biomarker for osteosarcoma.
