DDX11 and melanoma: To assess whether following transfection of melanoma cells with the DDX11 siRNA, DDX11 mRNA would be downregulated, we transfected WM1158 MGP melanoma cells with 25 nM of the DDX11 siRNA not conjugated to Cy5, and serving as control, with 25 nM of a pool of siRNAs comprised of four non-targeting siRNAs.
