Popis: | Background: MicroRNAs (miRNA) are regulatory small noncoding RNAs, which play a key role in many cancers. It has been found that miR-331-3p is involved in the development and progression of various cancers, but there are few reports in osteosarcoma. Methods: The public GEO database was used to analyze the survival difference of miR-331-3p in OS organizations. The level of cell proliferation assay was assessed by CCK-8 and colony formation. Tanswell and Wound-healing detect the transfer and invasion ability of miR-331-3p in OS. TargetScan, miRDBmiR, TarBase, and dual luciferase reporter gene assays were used to determine SOCS1 as a targeted regulator. Western blot and immunohistochemistry were used to detect the expression of protein levels. A mouse model of subcutaneously transplantable tumors is used to evaluate the proliferation of OS in vivo.Results: The low expression of miR-331-3p is negatively correlated with the overall survival of OS patients. Overexpression of miR-331-3p significantly inhibited cell proliferation, metastasis and invasion. miR-331-3p affects the occurrence and development of osteosarcoma by targeting the SOCS1/JAK2/STAT3 signaling pathway.Conclusion: miR-331-3p reduces the expression of SOCS1 by combining with its 3'UTR, thereby activating the JAK2/STAT3 signaling pathway to regulate the progression of OS. |
