The association between IRS-4/IRS-1 and the above-mentioned biochemical parameters in CRC was analysed by Pearson's correlation coefficient (r). ∆ = difference between the protein expression in matched adjacent normal colonic tissue (n=20) and in CRC tissue (n=20). Significance levels: ∗ p < 0.05; ∗∗ p < 0.01; ∗∗∗ p < 0.001; ∗∗∗∗ p < 0.0001.).
