The Affymetrix GeneChip Human Gene 1.0-ST array (Affymetrix, Santa
Clara, CA, USA) was used to define gene expression profiles from the samples.
Synthesis and labeling of cDNA targets, hybridization, and scanning of GeneChips
were carried out by the Integrative Genomics Core Facility at City of Hope.
Briefly, cRNA was generated according to the manufacturer’s protocol
using Affymetrix’s GeneChip Whole Transcript Sense Target Labeling Assay
Hybridization cocktails containing 5.5 μg of fragmented, end-labeled cDNA
were prepared and applied to GeneChip Human Gene 1.0 ST arrays. Hybridization
was performed for 16 h, and the arrays were washed and stained with a GeneChip
Fluidics Station 450 using FS450_0007 script. Arrays were scanned at 5 μm
resolution using Affymetrix GCS 3000 7G.
Raw intensity measurements of all probe sets were background-corrected,
normalized, and converted into expression measurements using Affymetrix’s
Expression Console v1.1.1. The Bioconductor “ArrayTools” package
was then used to identify the genes differentially expressed between the treated
and untreated samples. Significant genes were selected with a cutoff of adjusted
P < 0.05 and fold change of 2. The DAVID functional
annotation tool https://david.ncifcrf.gov/content.jsp?file=citation.htm) was
then used to identify modulated KEGG signaling pathways.

GeneChip Human Gene 1.0 ST Arrays (Affymetrix, Santa Clara, CA), consisting of 764,885 probe sets covering over 28,869 genes, was used to evaluate genes differentially expressed. The whole hybridization procedure was performed following the Affymetrix instructions. The amplification and labeling processes were verified using a GeneChip Eukaryotic Poly-A RNA Control Kit (Affymetrix) with exogenous positive controls. 15 µg of each biotinylated cRNA preparation was fragmented and placed in hybridization mixture containing biotinylated hybridization controls (GeneChip Expression Hybridization Controls, Affymetrix). Samples were then hybridized onto a GeneChip Human Gene 1.0 ST Array at 45 °C for 16 hours at constant rotation (60 rpm) in a Hybridization Oven (Affymetrix). Microarray scanned images were obtained with a GeneChip Scanner (Affymetrix) using the default settings. Images were analyzed with Affymetrix Gene Expression Analysis Software (Affymetrix). Comparisons were made between FRO-EV-1 and FRO-CBX7-1 samples, considering FRO-EV-1 as baseline. The fold change values, indicating the relative change in the expression levels between FRO-EV-1 and FRO-CBX7-1, were used to identify genes differentially expressed.

Total RNA was extracted from 25 mg tumor tissue using TRIzol reagent (Invitrogen), according to the manufacturer's procedure. cRNA was generated, labeled and hybridized to the Affymetrix (Santa Clara, CA) GeneChip® Human GENE 1.0 ST arrays by the Center for Medical Genomics at the Indiana University School of Medicine (Indianapolis, IN, http://cmg.iupui.edu/), as we have described previously [10 (link)]. The hybridized GeneChip® Human GENE 1.0 ST arrays were scanned using a Affymetrix GeneChip Scanner 3000 and analyzed using the Affymetrix Microarray Analysis Suite (MAS) version 5.0. The average density of hybridization signals from independent slides (4 slides per biopsy) was used for data analysis and genes with signal density less than 300 pixels were omitted from the data analysis. Genome-wide DNA methylation analysis using the Infinium HumanMethylation27 BeadChips (Illumina, San Diego, CA) was performed as previously published [12 (link), 13 (link)]. The gene expression analysis results are available for download at Gene Expression Omnibus data repository at the National Center for Biotechnology Information (NCBI) under the accession number GSE55410.

Twelve tumors (n=6 with 12q13-q14 amplification; n=6 without 12q13-q14 amplification) were selected from 57 cases reported in a previous study (9 (link)). Criteria for selection included PAX3-FOXO1 expression, prior analysis by copy number arrays (9 (link)), and availability of RNA. Oligonucleotide microarray expression analysis was performed on the 12 selected cases using the Affymetrix GeneChip Human Gene 1.0 ST Array at the University of Pennsylvania Microarray Facility. We defined a gene as overexpressed in a sample if its expression level was >1 standard deviation (SD) from the mean expression level of that gene across all samples. More stringent analysis was also performed by defining overexpression as >2 SD from the mean. The total number of overexpressed genes in each sample was used as a relative measure of E2F pathway activation. Additional details are described in Supplemental methods.

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.
