مستخلص: MicroRNA-342–3p (miR-342) has been shown to act as a tumor-suppressor in different cancer types. However, the role and therapeutic implications of miR-342 via modulation of Cofilin 1 (CFL1) has not been studied in any type of cancer. Given the importance of Cofilin signalling in breast, this study was undertaken to explore the therapeutic implications of miR-342 and its target CFL1 in breast cancer. Herein, we found that miR-342 was significantly (P < 0.05) downregulated in breast cancer tissues and cell lines. Functional assays revealed that overexpression of miR-342 caused a significant (P < 0.05) inhibition of the proliferation, colony formation, invasion and migration of the MDA-MB-436 and CAMA-1 breast cancer cells via induction of apoptosis. Bioinformatic approaches and the dual luciferase reporter assay confirmed the interaction between miR-342 and its target CFL1. Moreover, we found that CFL1 was aberrantly overexpressed in breast cancer tissues and cell lines. Overexpression of miR-342 caused remarkable depletion in the expression of CFL1 in MDA-MB-436 breast cancer cells. Silencing of CFL1 in CAMA-1 and MDA-MB-436 cells caused remarkable decrease in the proliferation, colony formation and migration of these cells, similar to that of miR-342 ovexpression. However, overexpression of CFL1 in MDA-MB-346 cells could avoid the tumor suppressive effects of miR-342. Our data provide novel information about the implications of miR-342 and its target CFL1 in breast cancer treatment. [ABSTRACT FROM AUTHOR]
