As shown in Fig. 2a and b, highly expressed HK2 was linked to poor prognosis of overall survival (OS) for cancers of CESC (p = 0.00069), KIRP (p = 0.043), LGG (p = 0.0000061), LIHC (p = 0.027), LUAD (p = 0.016), SARC (Sarcoma) (p = 0.025) and disease-free survival (DFS) for cancers of KICH (p = 0.048), LGG (p = 0.0000058) within the TCGA project. Here, HK2 is linked to cancer.
