Relationship among hENT1 expression, dCK expression, and WHO grades in meningiomas. The H-scores of hENT1 (A) and dCK (B) expression in surgical specimens from patients with low-grade (WHO grade I) and high-grade (WHO grade II/III) meningiomas. Horizontal bars show the mean ± SD. P values were calculated by the Student’s t-test. (C) Correlation between hENT1 and dCK expression in surgical specimens from meningioma patients. R-squared (R²) and P values were calculated by a linear regression analysis. Abbreviations: dCK, deoxycytidine kinase; hENT1, human equilibrative nucleoside transporter 1.
