Fig. 3From: Total DNA methylation as a biomarker of DNA damage and tumor malignancy in intracranial meningiomasThe total m5C contents (R) in DNA isolated from different intracranial meningioma tissues divided into the malignancy grades (WHO I represents the tumors of lowest malignancy, while WHO III relates to the most malignant tumors). Grade I tumors are characterized by mean R around 1.6, grade II – 1.4, and grade III – 1.1Back to article page
