NCAPG and glioblastoma: As shown in Figure 5A, NCAPG was located in the cytoplasm, and the χ2 test showed that the expression of NCAPG in GBM (WHO 4) was significantly higher than that in LGG (WHO 1–3) (P<0.001) (Table 1), suggesting that NCAPG expression was positively correlated with histological grade (Figure 5B).
