Overexpression of CDK5 reduces the inhibitory effects of miR-505-5p in CC.Taken together, these results determine that miR-505-5p is a tumor suppressor miRNA which regulates tumor cell proliferation, migration, and invasion via binding to the functional target CDK5 and demonstrates its potential for future use in the treatment of CC.
In conclusion, these findings demonstrated that DLX6-AS1 functioned as an oncogenic role that promoted BC proliferation and invasion through miR-505-3p/RUNX2 axis, which might serve as a potential therapeutic target for BC treatment.
The results of cell experiments revealed that an overexpression of miR-505 could significantly inhibit BCa cell proliferation, migration and invasion, whereas a downregulation of miR-505 significantly enhanced BCa cell proliferation, migration and invasion (P<0.05).
In conclusion, miR-505 levels are decreased in osteosarcoma tissues, and reduced miR-505 expression is significantly associated with poorer clinical prognosis in patients with osteosarcomas. miR-505 inhibits osteosarcoma cell proliferation, migration and invasion by regulating HMGB1.
In Ca-Ski and HeLa cells, lentivirus-mediated miR-505 upregulation suppressed cancer proliferation and invasion in vitro, and tumorigenicity in vivo, whereas miR-505 downregulation had no functional effects.
In this study, we show that microRNAs (miR) miR-505-5p and miR-520c-3p target the 3'-UTR of S100A4 and inhibits its expression and its mediated migration and invasion.
