AGO2 and breast carcinoma: Given that decreased expression of these two miRNAs leads to EMT interruption and inhibits tumor metastasis, along with a reduction in AGO2 (Figure 3G), representative expression levels relevant to mesenchymal proteins, including slug and vimentin, were significantly lower in both breast cancer cell lines treated with UA than in negative control cells in Western blot image analysis (Figure 3H–J).
