To further validate TTK’s role in lung cancer prognosis, the overall survival analyses of GEPIA [14], Kaplan–Meier’s Survival Analysis and the Okayama (GSE31210) cohort in the Kaplan-Meier’s (KM) plotter [15] revealed patients of higher levels of TTK expression survived shorter than in lung cancer patients with lower expression levels (Figure 1E). Here, TTK is linked to lung carcinoma.
