PERK expression was not significantly correlated with the prognosis of other cancers, such as cervical squamous cell carcinoma (p = 0.054), esophageal adenocarcinoma (p = 0.27), kidney renal clear cell carcinoma (p = 0.26), lung squamous cell carcinoma (p = 0.071), ovarian cancer (p = 0.34), pancreatic ductal adenocarcinoma (p = 0.24), pheochromocytoma and paraganglioma (p = 0.092), sarcoma (p = 0.11), stomach adenocarcinoma (p = 0.47), testicular germ cell tumor (p = 0.084), and uterine corpus endometrial carcinoma (p = 0.091, Figure 4). Here, EIF2AK3 is linked to cervical squamous cell carcinoma.
