Abstract:
Objective To explore the expression,role and mechanism of miR-375 in prostate cancer (PCa) cells.Methods PCa cells were cultured and transfected with plasmid,the migration and invasion of PCa were detected by Transwell;the expression of miR-375 and KLF4 mRNA were detected by qPCR;the expression of KLF4 were detect by Western blot;the potential target genes of miR-375 were analyzed by bioinformatics and verified by dual luciferase report.Results The expression of miR-375 were significantly up-regulated in the PCa;Inhibited the expression of miR-375 could significantly inhibit the migration and invasion of PCa cells.KLF4 was the potential target genes of miR-375,which verified through bioinformatics analysis and dual luciferase report.The expression of KLF4 were significantly down-regulated in the PCa.Inhibited the expression of miR-375 could significantly up-regulated the expression of KLF4.Inhibited the KLF4 expression was able to reverse the suppressive effect miR-375 has on the migration and invasion of PCa cells.Conclusion miR-375 promotes the migration and invasion of PCa via inhibiting the expression of KLF4 and play the oncogene role.MiR-375 can be used as therapeutic targets for PCa,and provide a new direction for the treatment of PCa.
