ETV6 and glioma: To investigate its expression in glioma patients, we examined ETV6 expression in 2 tissue microarrays (TMAs) from patients in the United States containing 3 normal brains, 6 GBM-adjacent normal brains, and 89 glioma tumor cores (n = 10, 10, 4, 65 for grade I–IV, respectively; US Biomax, BS17017b and GL805bt).
