Meanwhile, the expression of STC2 was associated with ploidy in 10 cancer types, with positive correlation in seven cancer types and negative correlation in three cancer tpyes, such as STAD (R = 0.11, p = 0.03), HNSC (R = 0.16, p < 0.001), MESO (R = −0.30, p = 0.001) and TGCT (R = −0.27, p = 0.001) (Figure 10D). This evidence concerns the gene STC2 and cancer.
