To confirm that Ang II was able to induce neuroblastoma differentiation, we analyzed the expression of MAP2 (a marker of neuronal differentiation that stabilizes microtubules in the dendrites of postmitotic neurons) [23, 24] and NF-H subunit (a marker of neuronal differentiation required for the radial growth of axons) [25, 26]. This evidence concerns the gene MAP2 and neuroblastoma.
