Analyzing The Cancer Genome Atlas cohort revealed that patients with squamous CC (SCC) in the high PDK1 expression group had a significantly worse survival prognosis than those in the low PDK1 expression group (P = 0.017) (Figure 1D); however, PDK1 expression was not significantly correlated with the cancer stage in patients with SCC (P > 0.05) (Figure 1C). Here, PDK1 is linked to cancer.
