METHOD: Kv1.3 and Kv10.1 channels were inhibited by specific siRNAs using a lipofectamine-based transfection in MCF-7 and MDA-MB-231 cells. After transfection, total RNA was isolated, and then miR-126 and miR-126* expressions were observed using RT-PCR. RESULTS: There was a negative correlation between Kv channels and miRNAs according to the characteristics of the breast cancer cells. The inhibition was observed not only in Kv1.3 but also in Kv10.1 in MCF-7 cells, and miR-126 and miR-126* expressions were downregulated compared to the control group (p < 0.001). The inhibition of these channels in MDA-MB-231 cells caused an upregulation of miR-126 and miR-126* expressions (p < 0.001). CONCLUSION: The miR-126 and miR-126* expressions differed according to benign and malign breast cancer cell lines. Furthermore, we found that miR-126/126* may interact with Kv1.3 and Kv10.1 voltage-gated potassium channels. Our study suggests and indicates the relationship between Kv channels and miRNAs in breast cancer cells.enCC0 1.0 Universalinfo:eu-repo/semantics/openAccessINDUCED APOPTOSISPROLIFERATIONMICRORNASETHERLYMPHOCYTERESISTANCEMIGRATIONONCOGENEInhibition of voltage-gated potassium channels affect expressions of miR-126 and miR-126*in breast cancer cell linesArticle116232115962N/A111121WOS:000508930100002Q3
