ALK and neuroblastoma: In sum, both murine NB cell lines, harbouring either the ALK‐F1178S gain‐of‐function mutation (Alk‐F1178S;Th‐MYCN) or with ALKAL2 ligand overexpression (Rosa26_Alkal2;Th‐MYCN), were sensitive to ALK inhibition, suggesting that ALKAL2‐driven NB may respond to ALK TKI treatment.
