Similarly, CBX4 expression levels were evaluated against cancer stages which are categorized into normal (n = 41), stage I (n = 45), stage II (n = 110), stage III (n = 80), and stage IV (n = 39), and the statistical significance was shown as follows: PNormal–vs–Stage1 < 0.001; PNormal–vs–Stage2 < 0.001; PNormal–vs–Stage3 < 0.001; PNormal–vs–Stage4 < 0.001; PStage1–vs–Stage2 = 0.73; PStage1–vs–Stage3 = 0.053; PStage1–vs–Stage4 = 0.087; PStage2–vs–Stage3 = 0.0786; PStage2–vs–Stage4 = 0.1; PStage3–vs–Stage4 = 0.794 (Figure 3C right). The gene discussed is CBX4; the disease is cancer.
