In 11 types of cancers, STC2 expression was associated with MSI, including SARC (R = 0.25,p < 0.001), LUSC (R = 0.11, p = 0.018), THYM (R = 0.29, p = 0.001), LIHC (R = 0.11, p = 0.03), TGCT (R = 0.24, p = 0.002), COAD (R = −0.12, p = 0.046), COADREAD (R = −0.11, p = 0.03), LAML (R = −0.18, p = 0.045), BRCA (R = −0.11, p < 0.001), STES (R = −0.11, p = 0.008), KIPAN (R = −0.20, p < 0.01) (Figure 10B). Here, STC2 is linked to cancer.
