Characterization of the expression of genes encoding proteins involved in the IGF pathway points out dysregulation of IGF pathway in bladder tumors. Levels of mRNA for IGF receptors, ligands, and binding proteins (Log2 scale), according to tumor stage, for the FBLAD-Exon dataset. *: p value = 0.01 to 0.05 **: p value = 0.001 to 0.01 ***: p value ≤0.001
