18-38% percent of neuroblastomas show amplification of the MYCN gene, while the majority of familial and 10% of sporadic neuroblastomas carry activating mutations in the ALK kinase domain (Mosse et al, 2008; reviewed in Aygun, 2018; Roskoski, 2013). Amplifications of the ALK gene have also been reported in this disease (Caren et al, 2008). ALK and MYCN may play cooperative roles in driving progression of neuroblastoma (Zhu et al, 2012; Mosse et al, 2008; reviewed in Roskoski, 2013).
High levels of ALK expression are seen in MYCN amplified neuroblastomas, and inhibition of ALK activity with tyrosine kinase inhibitors in a MYCN-amplified background reduces proliferation, cell migration and tumor growth in xenograft models, suggesting that ALK activity contributes to the oncogenic potential of MYCN-driven neuroblastomas (Hasan et al, 2013; reviewed in Hallberg and Palmer, 2013).
