Sub-cellular distribution of mature miRNAs after chemical inhibition of the Wnt/β-catenin signalling pathway in HL-1 cells. (A) Schematic representation of cellular treatment and sub-cellular fractionation. (B) Control of fractionation purity by qRT-PCR (snU6 and Gapdh) and Western blot (cropped images of parts of the same gel) analysis (GAPDH and H3). (C) qRT-PCR for miR-133a and miR-1 levels in total cell lysates and purified nuclear fractions. (D) Representative FISH image of HL-1 cells co-stained for miR-133a (red) and DAPI (blue) for nuclei visualization (n = 5); *p < 0.05; **p < 0.01.
