Sample GSM6217454 Query DataSets for GSM6217454
Status Public on Apr 05, 2023
Title GM21 fibroblasts, empty vector, biol rep 2, day 32
Sample type RNA
Source name GM21 fibroblasts empty vector time-alone control at day 32 post-transduction
Organism Homo sapiens
Characteristics cell type: skin fibroblast
Treatment protocol GM21-RASV12 fibroblasts and their empty vector counterparts were generated by retroviral transduction. GM21 fibroblasts constitutively expressing non-targeting and POU2F2-targeting shRNAs (pLKO.1-Neo-CMV-tGFP, pLKO.1-Neo-CMV-tGFP-TRCN0000245324 and pLKO.1-Neo-CMV-tGFP-TRCN0000245325) (Millipore-Sigma, Saint Louis, MO) were generated by lentiviral transduction and selected with 400 µg/ml neomycin for seven days. Cells were subsequently retrovirally transduced with RASV12
Growth protocol Human somatic GM21 foreskin fibroblasts (Coriell Institute, Camden, NJ) and WI-38 human fetal lung fibroblasts (European Collection of Authenticated Cell Cultures, Porton Down, UK) were cultured in a DMEM medium containing 10% fetal bovine serum (FBS) and 1× penicillin/streptomycin (Corning) at 37 °C in a 2% oxygen atmosphere
Extracted molecule total RNA
Extraction protocol Macherey-Nagel RNA XS columns. At least 200 ng RNA with RIN number 9 were used for library construction.
Label biotin
Label protocol Fragmented and labeled DNA targets were prepared according to the standard Affymetrix WT PLUS Reagent Kit protocol from 100 ng total RNA starting material and 5.5 µg single strand cDNA.
Hybridization protocol Hybridization cocktail of fragmented and labeled ss-cDNA were incubated 16hr, 60rpm at 45°C on Human Transcriptome Arrays 2.0. Genechips were washed and stained in the Affymetrix Fluidics Station 450 according to the standard GeneChip® Expression Wash, Stain, and Scan User Manual for Cartridge Arrays (PN 702731)
Scan protocol GeneChips were scanned using the Affymetrix GCS 3000 scanner.
Description Gene expression profiling of time alone in GM21 fibroblasts
Data processing Raw Affymetrix HTA 2.0 array intensity data were analyzed using open-source Bioconductor packages on R. All the data were normalized all together using the robust multi-array average normalization approach implemented in the oligo package (Carvalho and Irizarry, 2010). Internal control probe sets were removed and average expression deciles over all treatment and time points. Probes whose average expression was lower than the 4th expression decile were removed for subsequent analyses.
To remove sources of experimental variation and consider batch effects, data were finally corrected with the sva package. Principal component analysis and bi-clustering based on Pearson’s correlation and Ward’s aggregation criterion were used to confirm consistency between biological replicates and experimental conditions at each step of the pre-processing.
