For colon, although MKI67 and CIZ1-F levels correlated closely when the matched normal tissues were included in the analysis (P = 0.0020; Pearson Correlation), no correlation was found between levels across the cancer samples only, whereas CIZ1-RD was strongly correlated to MKI67 levels by both analyzes (P ≤ 0.00043; Pearson Correlation). The gene discussed is CIZ1; the disease is cancer.
