Abstract

Objective To explore the role of micro RNA-140-5p(miR-140-5p) in renal cell carcinoma (RCC) tumorigenesis. Methods The expression of miR-140-5p was determined by Real-time PCR in RCC (Caki-1, ACHN, OS-RC-2 and 786-O), and compared with kidney cortex proximal tubule cell (HK-2). After Caki-1 and 786-O cells were transfected with miR-140-5p inhibitor or mimic, the cell proliferation, cell cycle and related proteins were evaluated by MTS assay, flow cytometry and Western blotting. Results Caki-1 and 786-O showed the highest and lowest expression of miR-140-5p respectively. After the level of miR-140-5p in Caki-1 cells was decreased, cell proliferation was inhibited and cell number in G₀/G₁ phase was increased significantly, along with the reduction of cyclin D, E and CDK2, 4. Furthermore, the increasing level of miR-140-5p in 786-O cells promoted cell proliferation in vitro and tumorigenesis in vivo.Moreover, microarray demonstrated that protein kinase C isoform ε(PKCε), a markedly enhanced gene in RCC cells with the changed level of miR-140-5p. The combination treatment with down-regulation of PKCε, inhibitor/mimic induced changes of cell proliferation and cell cycle arrests were marked reversed in Caki-1 and 786-O cells.Conclusion These result indicate that miR-140-5p may promote cell proliferation via PKCεin RCC.
