Indeed, Cdc6 expression was significantly correlated with survival in patients whose cancer expressed three or fewer MCM2-7 genes at a high level (Wilcoxon-Gehan test, p = 0.004; Fig. 3E), but not in those patients whose cancer expressed four or more MCM2-7 genes at high level (p = 0.425; Fig. 3F). Here, CDC6 is linked to cancer.
