GADD45A and neoplasm: To show the statistical discrimination clearly, samples with nuclear GADD45α-IRS < 5 were classified as GADD45α -negative (Figure 1F), and those with GADD45α-IRS > 5 were classified as GADD45α positive (Figure 1E), the ratio of GADD45α positive was higher in tumor tissues than normal tissues (Table 4).
