Here, we report similar basal patterns of ALK phosphorylation between the neuroblastoma IMR-32 cell line, which expresses only the wild-type receptor (ALK(WT)), and the SH-SY5Y cell line, which exhibits a heterozygous ALK F1174L mutation and expresses both ALK(WT) and ALK(F1174L) receptors.

The case of the anaplastic lymphoma kinase (ALK) nicely exemplifies this, and cell line profiling has revealed that ALK mutations present in a subset of anaplastic large cell lymphomas (ALCLs), non-small cell lung cancers (NSCLCs), and neuroblastomas appear to sensitize cancer cells to treatment with selective ALK kinase inhibitors.
