Check if the same lab product or an alternative is used in the 5 most similar protocols
EGFR expression in the tumor was analyzed with NanoString analysis. Archival formalin-fixed paraffin-embedded tumor tissue was retrieved and manually macrodissected. Total mRNA was isolated from the macrodissected tumor tissues using a Qiagen miRNeasy kit (Qiagen, Valencia, CA, USA) according to the manufacturer’s instructions. The RNA sample was quantified with NanoDrop (Thermo Scientific, Wilmington, DE, USA) and regarded as adequate if it contained 400 ng at minimum. The sample was subsequently analyzed with the nCounter PanCancer Progression Panel (NanoString, Seattle, WA, USA) according to the manufacturer’s instructions [12 (link)]. NanoString data processing was done with the R statistical programming environment (v3.4.2). Considering the counts obtained for positive control probe sets, raw NanoString counts for each gene were subjected to technical factorial normalization, which was carried out by subtracting the mean counts plus two times the standard deviation from the CodeSet inherent negative controls. Subsequently, biological normalization using the included mRNA reference genes was performed. Additionally, all counts with P > 0.05 after a one-sided t-test versus negative controls plus two times the standard deviation were interpreted as not expressed over basal noise.

Quantitative Transcriptional Profiling of BT549 Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
RNA was extracted from BT549 cells 72 hours after siRNA transfection using the RNeasy Plus Kit (Qiagen) and quantified using NanoDrop, while quality was assessed using RNA Nano chips (Cat No: 5067–1511) on an Agilent 2100 Bioanalyzer. RNA Samples were then evaluated using the nCounter PanCancer Progression Panel (NanoString) according to the manufacturer’s directions. Alternatively, samples were evaluated using a custom-designed probe panel consisting of 72 test genes and 6 housekeeping genes (see Supplementary Table 1). Briefly, 100 ng of total RNA was hybridized overnight at 65 °C, then run on a NanoString Prep Station at maximum sensitivity. Cartridges were scanned on a NanoString Digital Analyzer at 555 fields of view. Raw count data was normalized using the nSolver analysis software version 3.0, which normalizes samples according to positive and negative control probes and the geometric mean of six housekeeping probes. Genes with normalized counts less than 20 were considered as background and were not included in the analysis. IPA analyses of NanoString data were performed using the Core Analysis function of the IPA software, v.31823283 (Qiagen Bioinformatics).

Total RNA was analysed using the 770-gene human nCounter PanCancer Progression panel (NanoString Technologies) according to manufacturer’s instructions. nCounter data were normalised to synthetic positive control targets and to housekeeping genes using nSolver Analysis software (version 4.0) (NanoString Technologies). A minimum mean count threshold was set to 20 counts, yielding a unimodal distribution of binary-logarithm-transformed counts. To remove between-batch variation, we used the pseudoreplicates approach of the removing unwanted variation-III normalisation method102 (link), applying k = 2. Statistical comparisons between experimental groups were carried out using two-sided Student’s t-tests (for experimental groups with equal variance; F-test) or two-sided Welch’s t-tests (where experimental groups displayed unequal variance; F-test) with Benjamini–Hochberg correction.
