Effects of 55 miRNA precursors and a negative control on IL-11 secretion in MDA-MB-231(SA) cells.

<p>Cells were transfected with miRNA precursors in 96-well plates. Medium was changed 24 hours after transfection (+/− TGF-β), and IL-11 concentration in the conditioned medium was measured 24 hours later. IL-11 concentration was normalized to the number of viable cells in the well. The scale of reduction (blue) or increase (red) in IL-11 concentration in the conditioned medium is represented in the color graph in the upper right hand corner of the figure.
