According to our IHC grading criteria, 8 PRDM1(+) and 8 PRDM1(−) FFPE samples and 2 samples of normal nasal mucosa were selected from the 58 NK/T lymphoma cases. Total RNA was extracted using RNeasy Mini Kit (Qiagen GmbH, Hilden, Germany) according to the manufacturer's instructions. After determining the RNA quality using the Agilent 2100 Bioanalyzer (Agilent Technologies, Inc.), 5 PRDM1(+) and 5 PRDM1 (−) specimens (P1, P2, P3, P4, P5 and N1, N2, N3, N4, N5, respectively) that met the criterion of NanoString analysis were identified. The 2 normal nasal mucosa samples were used as blank controls (B1, B2). The NanoString nCounter PanCancer Pathways Panel (NanoString Technologies, Inc., Seattle, WA, USA) includes 770 essential genes representing 13 Canonical Pathways: Notch, Wnt, Hedgehog, TGFβ, MAPK, STAT, P13K, RAS, chromatin modification, transcriptional regulation, DNA damage control, cell cycle (CC), and apoptosis. The NanoString nCounter assay was performed according to the standard protocol of NanoString with analysis and normalization of the raw NanoString data conducted using nSolver Analysis Software v3.0 (NanoString Technologies, Inc.). All procedures associated with mRNA quantification, including sample preparation, hybridization, detection and scanning, were carried out as recommended by NanoString Technologies, Inc.

Validating RNA-Seq with NanoString Profiling

Check if the same lab product or an alternative is used in the 5 most similar protocols
Gene expression was measured using the NanoString nCounter PanCancer Pathways Panel (NanoString Technologies, Seattle, WA, USA). Each Panel consists of 770 genes, including 13 housekeeping genes. A total of eight tumour samples (four responder and four non-responder) from the same patients as were analysed by RNA-Seq, were subjected to NanoString analysis, to validate RNA-Seq gene expression data, and to perform cancer pathway analysis. The samples were selected based on mapping efficiency (more than 90%) to the human genome (assembly GRCh37) based on our RNA-Seq data analysis. For each NanoString assay, 1 μg of total tissue RNA was isolated, mixed with a NanoString code set mix and incubated at 65°C overnight (16–18 hr). The reaction mixes were loaded on the NanoString nCounter Prep Station for binding and washing, and the resulting cartridge was transferred to the NanoString nCounter digital analyzer for scanning and data collection. Raw count data was preprocessed using the geNorm algorithm in nCounter Advanced Analysis ver. 2.0.115 (NanoString Technologies) (31 (link)). A quality check of raw data was conducted using nSolver Analysis Software ver. 4.0 and NanoStringQCpro ver. 1.14.0 (NanoString Technologies). Z-scores were generated for each gene from normalised data to perform further analysis.

Identifying Cell Signaling Pathways Affected by JQ1

Check if the same lab product or an alternative is used in the 5 most similar protocols
To identify cell signaling pathways affected by JQ1, multiplex gene expression analysis was performed using the nCounter® PanCancer Pathways Panel. Following JQ1 treatment, RNA was extracted from MDA-MB-231 and MDA-MB-453 cells as described above. The extracted RNA was subjected to an nCounter® PanCancer Pathways Panel (NanoString Technology, WA, USA) according to the manufacturer’s protocol. Briefly, capture probes, reporter probes, and total RNA were mixed with hybridization buffer and hybridized at 65 °C overnight. Then, the samples were processed on the nCounter Prep Station with wash reagents and an imaging cartridge. Hybridization occurred over 20 hours and was monitored in selected experiments.

NanoString Analysis of Immune and Pathway Genes

Check if the same lab product or an alternative is used in the 5 most similar protocols
NanoString was performed using the nCounter® PanCancer Immune Profiling panel (XT–CSO-HIP1-12) composed of 770 immune response genes and the nCounter® PanCancer pathways panel (XT–CSO-PATH1-12) comprised of 770 genes from 13 canonical cancer associated pathways (NanoString Technologies). RNA was extracted using the Highpure miRNA isolation kit (Roche) from FFPE blocks, following initial confirmation of tumor presence and content by two pathologists by H&E. For gene expression studies, 1 μg of RNA was used as per manufacturer's instructions (NanoString Technologies). All samples included in this study passed a quality check before the NanoString analysis. Raw NanoString results were normalized using standard NanoString housekeeping genes before comparing tumor-normal pairs. We performed a “Core Analysis” with the significantly differently expressed genes (after Bonferroni correction) in the Cancer Immune and separately with the significant results in the Cancer Pathways panel.

The High Pure RNA isolation Kit (Roche Diagnostics) was employed for RNA extraction from ER, ECR and EAR colonies according to the manufacturer's instructions, and concentrations were estimated using the Qubit 3.0 fluorometer (Invitrogen, Eugene, OR, USA). Purified RNA was analyzed using the nCounter® PanCancer Pathways Panel (NanoString Technologies, Seattle, WA), which includes 730 transcripts and 40 housekeeping genes. The hybridization steps were performed in a Verity thermal cycler (Applied Biosystems, South San Francisco, CA, USA). All processes of capture, cleanup, and digital data acquisition were performed with nCounterPrep StationTM and Digital AnalyzerTM (NanoString Technologies, Seatle, WA, USA) according to the manufacturer's instructions. The number of counts for each gene was extracted from the nCounter generated RCC files using nSolver analysis Software (version 4.0.70 NanoString Technologies) and exported to Microsoft Excel software. RNA counts were normalized using the positive controls and housekeeping transcripts, as described [34] (link). Finally, pathway analysis was performed using nCounter Advanced Analysis 2.0 from nSolver and STRING free software version 11.5 [35] (link). Only pathways identified by both methods in the same colony were considered.

Differential expression of key transcriptomic pathways was compared between the treatment groups (Ixazomib, Dinaciclib, Ixa + Dina) and DMSO control, with fold change and P values calculated based on nSolver’s recommended default settings. A Venn diagram was constructed to determine overlapping genes with a fold change of ≥ ±2 between PDXO1, 11 and 12. Gene set analysis and global significance scores were calculated from differential expression analysis-derived t-statistics for genes in a particular gene set or pathway, as defined by the software.

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.
