Effect of 5azadC on 3D invasion properties, DNA methylation and specific miR expression in WM-266-4 GFP cells. a Experimental scheme for spheroid invasion assays. b Six spheroids were analysed for each 5azadC concentration as indicated. Photos shown in a are representative of one spheroid per condition. c Histogram representing the mean invasion index (invasion area/spheroid initial area) calculated for 18 spheroids. d Mean methylation percentage for five CpG sites in LINE-1 sequences. e Specific MIR-155HG and MIR-199A2 promoter demethylation was evaluated on spheroids after 5azadC treatment. Median methylation of all the CpG sites is represented. f RT-qPCR analysis of mature miR-155, miR-199a-3p and miR-199a-5p. The relative quantity (RQ) was calculated using RNU6B gene as control. All experiments were performed in triplicate. SEM are shown and *P value < 0.05, **P value < 0.01, ***P value < 0.001. NS not significant
