Specifically, the lower expression of MYBL2 was associated with a favorable overall survival in LGG 15, LIHC 16 and NSCLC 17, high DKK1 was identified for gastric cancer 18, and NPTX2, which was moderately significant (p ≤ 0.05) for the survival 20, has been suggested to have prognostic value for GBM 19. Here, DKK1 is linked to glioblastoma.
