TP53 and glioblastoma: The importance of P53 in the response to the treatment in GBM patients, on one hand, and on the other hand possible footprint of P53-dependent apoptosis induction by the electrical field6; by choosing two GBM cell lines with different P53 status (U87 as wild type and U251 as mutated type (Table 4)), we struggled to assess the possible role of this gene status in the response obtained after ELF-EMF exposure.
