PATZ1 and glioblastoma: We have observed that PATZ1 protein is expressed in neurons (mainly in the nucleus) but not in glial cells of all perilesional normal brain tissues (Figure 1A), whereas it is expressed in a high percentage of GBM (69%) with a main nuclear, but sometimes cytoplasmic localization (Figure 1B, Supplementary Table 1) and oligodendrogliomas (54%) (Supplementary Table 2).
