For single-end library construction: Total RNA was depleted of rRNA using the Ribo-Zero rRNA Removal Kit (Epicentre). RNA libraries were prepared using the dUTP-based, Illumina-compatible NEXTflex Directional RN-Seq Kit (Bioo Scientific). For paired-end library construction (performed by BGI), total RNA was enriched for poly(A) mRNA with oligo(dT) beads and treated with buffer to yield 200–700 nt fragments. First-strand cDNA was synthesized using random hexamer primers; second-strand cDNA was synthesized using buffer, dNTPs, RNase H, and DNA polymerase I. cDNA was run on an Agarose gel for suitable fragment size selection, followed by a purification, adaptor ligation, and PCR amplification.

Normal HF-, Epd- and SCC-SCs were isolated as previously described (Ge et al., 2016 (link)). For wound-activated SCs (Wd-SCs), adult second telogen (P60) Sox9CreER; R26YFP female mice were subjected to full-thickness 7mm punch wounds. Seven days post-wounding, single cell suspensions were obtained by FACS as Lineage-YFP+ Integrin-α6+ (HF-derived) and Lineage-YFPneg Integrin-α6+ (Epd-derived). Cells were lysed with TrizolLS (Invitrogen) and total RNA was isolated with the Direct-zol RNA MiniPrep kit (Zymo Research) and submitted to the Genomics Resources Core Facility of the Weill Cornell Medical College for quality control (determined using Agilent 2100 Bioanalyzer, with all samples passing the quality threshold of RNA integrity numbers (RIN 8). Library constructions were performed using IlluminaTruSeq Stranded mRNA Sample Prep Kits, and sequencing was performed on an Illumina HiSeq2000 sequencing machine.
For RNA quantitative PCR, primers DNA oligos were synthesized from Eurofinsgenomics complementary DNAs were generated from 1μg of total RNA using the SuperScript Vilo cDNA synthesis kit (Life Tech), diluted and used as templates for real-time PCR performed with the 7900HT Fast Real-Time PCR System (Applied Biosystems) and gene-specific primers listed in Table S2. Glyceraldehyde dehydrogenase (GAPDH) was used as a loading reference.

Purified RNA was quantified and assessed for quality using an Epoch 2 microplate spectrophotometer (BioTek). cDNA libraries were prepared from 500 ng RNA per sample. Libraries were then sequenced on an Illumina HiSeq 2000 sequencing machine using paired-end sequencing with a read length of 100 nucleotides. Adaptor sequences and low-quality reads were removed using Trimmomatic, and the RNA-Seq reads were then mapped to the C. elegans genome using STAR 2.5.3a with default settings. Transcript abundance, measured as read counts per gene, was extracted using HTSeq. Differential gene expression analysis was performed using GFold34 (link). Gene ontology (GO) analysis was conducted using DAVID.

Transcriptome Profiling of Tumor and Normal Tissues

Total RNA was isolated from frozen tumor and matched normal tissues using the reagent Trizol (Invitrogen). The sequencing library was constructed according to Illumina's TruSeq RNA Sample Preparation Protocol. Poly-A containing mRNA was purified from total RNA using magnetic beads with oligo-dT, followed by fragmentation. First-strand cDNA was synthesized using random hexamers and reverse transcriptase. Second-strand cDNA was synthesized with high quality deoxyribonucleotide triphosphates (dNTPs), ribonuclease H (RNase H), and DNA polymerase. Then the new double-strand cDNA was end-repaired and a single nucleotide “A” was added. Different in-house designed 6 bp adapters were ligated to the corresponding samples. DNA fragments with selected size and adapters were purified and amplified by PCR. After normalization, the DNA sample libraries were pooled into 4 libraries, and the pooled libraries were sequenced on an Illumina HiSeq 2000 sequencing machine.

Transcriptomic Response of N2 and npr-1 Worms to Pathogens

Check if the same lab product or an alternative is used in the 5 most similar protocols
N2 and npr-1(ur89) worms were exposed to either PA14, BT B-18247 or OP50 for either 12 or 24 h of exposure. The experiment had 3 replicates of each treatment combination (a total of 36 samples across treatment combinations and replicates). Exposure experiments were performed on large Agar plates (15 cm diameter), which were fully covered with a bacterial lawn, thus minimizing escape responses and resulting in comparable occupancy rates across the treatment combinations. At both time points (12 & 24), worms were washed off the exposure plates with PBS containing 0.3 % Tween20® and resuspended in TRIzol® (Life Technologies) reagent. Prior to RNA extraction, worm suspensions were treated five times with a freeze-thaw cycle using liquid nitrogen and a thermo block at 45 °C. RNA extraction was performed using a NucleoSpin® mRNA extraction kit (Macherey-Nagel). RNA samples were treated with DNAse, and then stored at –80 °C. RNA libraries were prepared for sequencing using standard Illumina protocols. Libraries were sequenced on an Illumina HiSeq™ 2000 sequencing machine with a paired-end strategy and read length of 100 nucleotides.

Hth-Exd-Ubx Homeodomain SELEX Experiment

Check if the same lab product or an alternative is used in the 5 most similar protocols
The Hth-Exd-Ubx SELEX experiment was carried out following previously published methods8 (link),61 . In brief, after expressing and purifying the wild-type homeodomain proteins, a final concentration of 50 nM was assembled, incubated with excess DNA (10–20 fold) for 30 minutes and loaded onto an EMSA gel. A DNA library with 30 randomized bases was used. The TF-bound fraction was isolated from the gel and amplified and either subjected to another round of enrichment or prepared for sequencing. Three rounds of enrichment were performed. After each selection round, the DNA was extracted from the gel and amplified by using Ilumina’s small RNA primer sets. Sequencing barcodes were added in a five-cycle PCR step, and the final library was gel-purified using a native TBE gel before sequencing. Libraries were sequenced at the New York Genome Center using separate lanes on an Illumina HiSeq 2000 sequencing machine.

Libraries for HthFL-Exd and HthFL-ExdR2A,R5A (Lib-16) were sequenced using a v2 75-cycle high-output kit on an Illumina NEXTSeq Series desktop sequencer at the Genome Center at Columbia University. Libraries Lib-Hth-F and Lib-Hth-R with either Hth or Exd shape-readout mutant in complex with the respective other wild-type protein and Dfd, as well as the Lib-30 HthFL-Exd-Dfd experiment were all sequenced at the New York Genome Center using separate lanes on an Illumina HiSeq 2000 sequencing machine. Libraries Lib-Hth-F and Lib-Hth-R with wild-type proteins were also sequenced on a HiSeq instrument at a different facility. Libraries were trimmed to remove Illumina- and library-internal adapter sequences using the FASTX toolkit (Hanon lab) and loaded into the R environment using the R package named SELEX (http://bioconductor.org/packages/SELEX) (Riley, 2014 (link)).

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.
