MAGED2 and glioma: When the percentage of high mRNA MAGED2 expression in low-grade (20.41%) and high-grade (36.73%) gliomas was compared to that of normal brain tissue, significant differences were found (p < 0.001 and p < 0.001, respectively); however, no significant differences were found between high-grade and low-grade glioma (p = 0.82; Figure 2C).
