Example of a mixed TF-sponge module. A) As in Figure 5A, this time for a prototype of mixed TF-sponge module. B)-C) As in Figure 5B-C, this time for: PVT1 versus CDH1, CDH1 versus mir-141, PVT1 versus mir-141, and ZEB1 versus mir-141. y- and x-axis: normalized read counts from TCGA (log2-scale); r = Pearson correlation coefficient, p = p-values. Correlations and p-values are computed by using the routine corr of MATLAB. Each p-value is the probability of getting a correlation as large as the observed value by random chance, when the true correlation is zero.
