Survey of cell cycle and proliferation upon GIRK1 overexpression in MCF-7 cells. a Original results from the assessment of cell cyle using gated cell sorting according to fluorescence intensities for PerCP-A (x-axis) and APC-A (y-axis) for different experimental groups. % of cells for the given experiment is stated in respective colors besides the plot. b Statistics for the percentage of time spent in the different phases of the cell cycle Mean values ± SEM were plotted. N was (in parenthesis behind each experimental group): was: MCF-7^WT (8) / MCF-7^eYFP (12) / MCF-7^GIRK1a (16) / MCF-7^GIRK1d (12) / MCF-7^GIRK1d (6). G₁/G₀ fraction of MCF-7^GIRK1d differs statistically significant at the p < 0.05 level from the one of MCF-7^GIRK1a. One way ANOVA was used for analysis of statistical significance
