MACC1 and glioblastoma: Evaluating the mechanical properties of single GBM cells, an increased MACC1 expression was associated with an increased resistance to deformation (Young’s modulus) of U251 (E U251/EV = 1.33 kPa, E U251/MACC1 = 1.61 kPa) and U138 (E U138/EV = 1.69 kPa, E U138/MACC1 = 2.16 kPa) cells.
