Illumina Tight Insert Fragment, 400 bp–2 ug of DNA was sheared to 400 bp using the Covaris LE220 and size selected using the Pippin (Sage Science). The fragments were treated with end-repair, A-tailing and ligation of Illumina compatible adaptors (IDT) using the KAPA-Illumina library creation kit (KAPA Biosystems). The prepared libraries were quantified using KAPA Biosystems’ next-generation sequencing library qPCR kit (Roche) and run on a Roche LightCycler 480 real-time PCR instrument. The quantified libraries were then prepared for sequencing on the Illumina HiSeq sequencing platform using a TruSeq Rapid paired-end cluster kit, v.2, with the HiSeq 2500 sequencer instrument to generate a clustered flowcell for sequencing. Sequencing of the flowcell was performed on the Illumina HiSeq 2500 sequencer using HiSeq Rapid SBS sequencing kits, v.2, following a 2 × 250 indexed run recipe.

Immunoprecipitations were carried out as described (Tavares et al. 2012 (link); Latos et al. 2015 (link)) and are detailed in the Supplemental Material. DNA from four immunoprecipitations was pooled for each library generated with the NEB Next DNA library preparation master mix (New England Biolabs, E6040) according to the manufacturer's instructions. Libraries were amplified using 18 PCR cycles, purified using Agencourt AMPure XP SPRI beads (Beckman Coulter, A63881), and size-selected on an agarose gel. DNA was extracted using the QiaQuick gel extraction kit (Qiagen), and its concentration was determined using the KAPA Illumina SYBR Universal Lid Q kit (KAPA Biosystems, KK4824) and Bioanalyzer 2100 system (Agilent).

The custom capture oligo set was designed by the SureDesign platform from Agilent Technologies (SureSelectXT Custom Capture Oligo) against SCN9A, SCN10A, and SCN11A. This set was specifically designed to capture all exons, the proximal promoter sequence, as well as limited intron sequences and untranslated regions near exons. The target-captured sequencing libraries were constructed using the KAPA LTP Library Preparation Kit (Kapa Biosystems, Inc., Wilmington, MA) combined with a SureSelectXT Reagent Kit (Agilent Technologies), and sequenced on an Illumina Hiseq 2500 sequencer (Illumina, Inc, San Diego, CA) at read length of paired-end 2 × 100 bp. Targeted exome sequencing was performed on an initial cohort of 46 IBD patients that included a mixture of individuals with and without inflammation and abdominal pain. Generated reads were aligned with the GRCh37 human reference genome using the Burrows-Wheeler alignment (20 (link)). Variant detection and analysis were performed using the GATK Best Practice for germline SNP/indel finding workflow (Broad Institute). ANNOVAR software (21 (link)) was used to annotate the variants and identify synonymous, non-synonymous, and deleterious variants for further analysis.

RNA was isolated from immortalized BCR-ABL1p185+Cdk8fl/fl and Cdk8Δ/ΔVav-Cre cells. Single-end, 50 bp sequencing of libraries prepared with the Lexogen SENSE mRNA-Seq library preparation kit was performed on an Illumina HiSeq-2500 sequencer. After quality control of raw data with FastQC and removement of adapters and low quality reads with Trimmomatic (version 0.36), reads were mapped to the GENECODE M13 genome using STAR (version 2.5.2b) with default parameters. Then, featureCounts from the Subread package (version 1.5.1) was used to obtain gene counts for union gene models. Differentially expressed (p-adjust < 0.05 and fold change > 2) treatment dependent (Cdk8fl/fl dimethyl sulfoxide (DMSO) vs. Cdk8fl/fl Senexin B; Cdk8Δ/ΔVav-Cre DMSO vs. Cdk8Δ/ΔVav-Cre Senexin B) and genotype-dependent (Cdk8fl/fl vs. Cdk8Δ/ΔVav Cre) genes were identified using DESeq2 (version 1.18.1). For the heatmap, centered and scaled regularized log-transformed54 (link) library size-normalized counts were visualized using the aheatmap function of the R package NMF (version 0.20.6). The command-line version of GSEA was used for GSEA55 (link) and pathway analysis was performed with EnrichR56 (link) using either significant up- or downregulated genes (fold change > 2, padjust < 0.1) of Cdk8fl/fl vs. Cdk8Δ/ΔVav Cre cell lines.

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.
