Fig. 1: POLE2 is highly expressed in human GBM.

A The mRNA expression of POLE2 in GBM samples (169 cases) and normal samples (5 cases) was compared from TCGA-GBM database. B The representative picture of the expression level of POLE2 in normal tissues and tumor tissues with different grades was detected by immunohistochemistry (IHC). The magnification is 200.
