MiR-613 promotes cell proliferation and invasion in cervical cancer via targeting PTPN9

Eur Rev Med Pharmacol Sci. 2018 Jul;22(13):4107-4114. doi: 10.26355/eurrev_201807_15402.


Objective: To investigate the potential effects of miR-613 on the development of cervical cancer (CC) and the relevant mechanism.

Patients and methods: The expression level of miR-613 was detected in CC tissues and cells (siHa) by comparing with corresponding adjacent normal tissues and normal human embryonic kidney cells (293T). Luciferase assay was performed to evaluate the interaction between miR-613 and PTPN9. The effects of the miR-613 on siHa cells were determined by subsequent experiments including cell proliferation, invasion and migration.

Results: In our study, miR-613 was found up-regulated in CC tissues and the same result was found at cellular level. The potential target of miR-613 was analyzed by three public databases. We found that tyrosine-protein phosphatase non-receptor type 9 (PTPN9) was a direct target of miR-613, and Luciferase assays confirmed our hypothesis. The subsequent experiments showed that decreased expression of PTPN9 resulting from up-regulation of miR-613 could promote the cell proliferation, invasion and migration of CC cells.

Conclusions: We showed the promotion function of miR-613 on CC by targeting PTPN9 and revealed that miR-613/PTPN9 axis might be a potential therapeutic target for the treatment of CC.
