Figure 1. TTK expression profile in papillary thyroid cancer (PTC). (A) TTK expression in pan-cancer. The elevated TTK mRNA level in PTC by the (B) unpaired and (C) paired t-tests using TCGA data. Higher TTK (D) mRNA and (E) protein expression in PTC cells. Relationship between TTK and (F) N stage, as well as (G) histological subtype. 1: PTC-classical; 2: PTC-tall cell; 3: PTC-follicular.
