Cortical neurons were treated with inhibitors or ligands 4 h after plating and were fixed 33–38 h after treatment for analysis. For IGF‐1R, inhibitors or activators were added in starvation medium (serum‐free Neurobasal medium, supplemented with 2% B27 minus insulin, 1% L‐glutamine, 50 IU/ml penicillin, and 50 μg/ml streptomycin). The following inhibitors and ligands were used: TAE684 (NVP‐TAE684, Selleckchem, #1108), crizotinib (PR‐02341066, Selleckchem #1068), LY 294002 (Tocris), BKM120 (Buparlisib) (Selleckchem, #S2247), AG1024 (Selleckchem #S1234), PPP (CAS 477‐47‐4, Santa Cruz, scbt #24008), and recombinant murine IGF‐1 (Peprotech).
ALKAL2‐containing conditioned medium (ACM) was generated as described previously (Guan et al, 2015 (link)) with slight modifications. Briefly, HEK293T cells, in 10 cm plates, were transfected with 8.0 μg pcDNA3‐FAM150B‐HA using the calcium phosphate method. After 16 h, media was replaced with starvation medium (DMEM, supplemented with 0.2% FBS, 50 IU/ml penicillin, and 50 μg/ml streptomycin) and ALKAL2‐conditioned medium was collected after 36 h. Cortical neurons were treated with CCM and ACM, supplemented with 2% B27 and 1% N2. Activation of wild‐type endogenous ALK was confirmed in IMR‐32 human neuroblastoma cells.

The CLB-GA time series dataset has been described before [31 (link)]. The neuroblastoma CLB-GA cell line (ALKR1275Q) was cultured in RPMI-1640 medium (Invitrogen), supplemented with fetal bovine serum (10%), kanamycin (100 μg/ml) penicillin/streptomycin (100 IU/ml), L-glutamine (2 mM) and HEPES (25 mM) (Life Technologies), and maintained at 37°C in a 5% C02-humidified environment. At different time points (10, 30 minutes, 1, 2, 4 and 6 hours) after treatment with 0.32 μM of the small molecule ALK inhibitor NVP-TAE684 (hereafter TAE684) (SelleckChem, S1108) or DMSO (VWR) as solvent control, cells were harvested and RNA quality was analysed using Experion (Bio-Rad) prior to gene-expression profiling. Samples were labelled and hybridized to the Sureprint G3 human GE 8x60K microarrays (Agilent Technologies), according to the manufacturer’s guidelines and starting from 200 ng RNA. The data was normalized with the vsn method in R version 3.3.3 (packages vsn and limma). The R package BioMart was used to annotate gene names to their corresponding probes. Probes detecting at least a two-fold higher expression than the negative control probes of the array in at least 60% of the DMSO or TAE samples, were selected as background correction. Data can be accessed through ArrayExpress (accession number E-MTAB-3206) [31 (link)].

Crizotinib, NVP-TAE684 and LDK-378 for use in tissue culture studies were purchased from Selleck Chemicals (Houston, TX), dissolved in DMSO and stored at −20C. For in vivo use, Crizotinib was obtained from Aok Bio (Shanghai, China), and NVP-TAE684 and LDK-378 were sourced from MedChemExpress (Monmouth Junction, NJ). The purity of all drugs were greater than 95%, as assessed by LC-MS analysis. ALK inhibitors were suspended in capryol 90 (Gattefosse Corp., Paramus, NJ) for oral gavage of animals. Vincristine (V), actinomycin D (A) and cyclophosphamide (C) were all obtained from the St. Jude pharmacy and were dissolved in sterile saline. They were administered by i.p. injection using a schedule deemed efficacious in pediatric patients (V given weekly at 0.38mg/kg; A given once at 0.5mg/kg; C given once at 125mg/kg).
Antibodies for ALK (31F12 mouse monoclonal, cat# 3791) and G3PDH (D16H11 rabbit HRP-conjugated monoclonal, cat# 8884) were purchased from Cell Signaling (Danvers, MA). siRNA targeting ALK and GFP-tagged RNA used as a control for transfection efficiency were obtained from OriGene (Rockville, MD). The former consists of 3 unique 27mer siRNA duplexes targeting different regions of the ALK mRNA and scrambled siRNA were used as negative controls.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
