HTT and neuroblastoma: The goal of the current study was to examine the effect of adeno‐associated viral (AAV) mediated‐expression of that peptide (CaM‐peptide) in differentiated neuroblastoma SH‐SY5Y cells that stably express an N‐terminal (63 amino acids in length) fragment of huntingtin containing 148 glutamines (SH‐SY5Y‐htt‐N63‐148Q cells).
