Similarly, the correlation between GD2 expression and tumor growth rate was moderate in both the groups of mice [Pearson’s correlation values 0.530 (t test 0.0001) and 0.673 (t test 0.0001) respectively] showing that in our experimental system also GD2 is less prognostic of tumor aggressiveness than MCM2 and CA9 (Figure 5I,J). The gene discussed is CA9; the disease is neoplasm.
