Global analysis of miRNA-Cq distribution and relative expression after irradiation in the different HPK samples (All-paired Tukey-Kramer tests). Each point represents a miRNA Cq in non-irradiated (A) or irradiated (B) state, or miRNA relative expression (irradiated vs non-irradiated) (C). Box & whiskers plots represent first decile, first quartile, medium, third quartile and ninths decile of data in each cell samples. The black line corresponds to the mean Cq for all samples. Greek letters besides box plots indicate differences between means: same letters-donors indicate no difference between means, different letters-donors indicate significant difference of means, double letters-donors indicate no difference with single letters.
