MRNA expression profiles of TAE-684 treated or shALK transfected neuroblastoma cell lines

ABSTRACT: Human wild-type ALK (SK-N-AS, NGP, IMR-32), ALKR1275Q (CLB-GA, LAN-5, UKF-NB-3), ALKF1174L (SK-N-SH, Kelly, SMS-KCNR) and ALK amplified (NB-1) neuroblastoma cell lines were treated in triplicate with 0.3M-k_M NPV-TAE-684 (Novartis/SelleckChem) or DMSO (VWR) for 6 hours, followed by RNA isolation and gene expression profiling. For shRNA mediated knockdown, pGIPZ-ALK shRNAmir and pGIPZ-non-silencing control shRNAmir vectors were used (Open Biosystems). The ALK shRNA was directed against a part of exon 26 in the tyrosine kinase domain of ALK (target sequence: TGGAAGGAATATTCACTTCTAA). Lentiviral particles were produced according to manufacturerM-^IM-[M-*s protocol (Open Biosystems). On day 2 post-transduction of neuroblastoma cells, the transduction efficiency was determined by flow cytometry and microscopic analysis of GFP-positive cells (>90% so no further selection was performed). Cells were subsequently harvested for expression profiling. Labeling of the RNA samples and hybridisation to the Affymetrix HG-U133plus2 arrays was performed using the manufacturerM-^IM-[M-*s protocol starting from 1 M-eM-5g of RNA.
