CA9 and neoplasm: Similarly, we also found a strong Pearson’s correlation between the expression of MCM2/CA9 and tumor nodule growth (Pearson’s correlation values 0.8557 (t test 0.0078) and 0.9010 (t test 0.0025), respectively) in the group of mice treated with cisplatin, thus strengthening what observed in untreated mice (Figure 5C,D).
