Supplementary Figure S1. Effect of knocking down one AGO on other AGO expression in MCF7 cells. (A-D) qRT-PCR analysis of all four Argonautes following an inhibition of one Argonaute. All data were normalized to GAPDH. The transfection concentration of all used siRNAs was 25 nM. MM: an negative control RNA duplex (25 nM). Error bars represent standard deviations, calculated from three independent experiments. ***p
