In TCGA_CESC, compared with the paracancerous (n = 3), the expression level of PDIA3 in the cervical cancer tissue (n = 304) was significantly increased (P < 0.05 represents a significant difference), and PDIA3 showed strong immunoreactivity in the cervical cancer tissue (Figure 2) [13]. Here, PDIA3 is linked to cervical cancer.
