Abstract:
Aim To explore the role of miR-27a on the proliferation and metastasis of renal cell carcinoma (RCC) and its mechanism. Methods The expression of miR-27a in RCC cancer tissues, para-carcinoma tissues, RCC cells (Caki-1, 786-0 and ACHN) and normal renal tubular epithelial cells ( HK2) were detected by RT-qPCR. After miR-27a-inhibitor transfect-ed into 786-0 and ACHN cells, cell proliferation was measured by CCK-8 assay; cell colony formation was detected by colony formation assay; cell migration and invasion were detected by cell wound healing assay and Transwell assay, respectively; the pretein expression of P-catenin was detected by Western blot. After trans-fected miR-27a inhibitor into ACHN cells then treated with LiCl (Wnt/p-catenin signal agonist), cell proliferation , migration and invasion were detected. Results The expression of miR-27a in RCC cancer tissues was significantly higher than that in para-carcinoma tissues, and increased with stage progression. Compared with HK-2 cells, the expression levels of miR-27a in RCC cells were elevated. After transfection with miR-27a inhibitor, the cell colony formation, cell prolifera-tion, invasion and migration ability of 786-0 and ACHN cells were significantly reduced. MiR-27a in-i hibitor reduced the expression of p-catenin in ACHN cells. LiCl promoted the proliferation, invasion and migration ability of ACHN cells transfected with miR-27a inhibitor. Conclusions MiR-27a is highly expressed in RCC cancer tissues and RCC cells, and knockdown of miR-27a inhibits proliferation and metastasis in RCC cells through Wnt/p-catenin signaling pathway.
