EMX1 and neoplasm: The RT‐qPCR results indicated that the EMX1 expression was reduced in SCG tissues versus that in the adjacent normal tissues (Figure 1c), and it was reduced as the tumor grade increases (Figure 1d) (WHO I vs. WHO II: p = .0040; WHO I vs. WHO III: p = .0005; WHO I vs. WHO IV: p < .0001; WHO II vs. WHO III: p = .0330; WHO II vs. WHO IV: p = .0007; WHO III vs. WHO IV: p = .0407).
