Leaf material from 74 individuals from 19 A. thaliana demes (four individuals from each deme except for two individuals from JBB) (Dataset S1) were used for DNA extraction (SI Appendix, section S4) and genome resequencing. Genome resequencing was performed on an Illumina HiSeq 2500 sequencing system in paired-end mode with data processing described in SI Appendix, section S5.
Frozen leaf material from one individual of the JBB, T11, and PA10 demes was used to perform de novo genome assemblies with linked reads generated with the 10× Genomics Chromium platform and Supernova assembler (SI Appendix, section S6). Samples S1 (T11), S2 (JBB), and S12 (PA10) were sequenced on an Illumina HiSeq 2500 sequencing system in rapid run mode (250-bp or 150-bp paired-end sequences).

Transcriptome Analysis of Heart Failure

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sequencing was performed for all patients on the Ion Torrent PGM utilizing the Ion 316 chip. Coverage analysis as well as mapping the reads and alignment was done using the Ion Torrent Browser Suite™. Gene expression profiles from the PGM sequencer were validated with a subsequent population by performing RNAseq with the Illumina Hiseq2500 sequencing system. RNAs from 7 non failing and 3 failing samples were sequenced using the Illumina Hiseq2500 sequencing system (University of Nebraska Medical Center, DNA core facility). All paired end sequencing adaptors were trimmed using fqtrim and any reads shorter than 36 bases were discarded. A quality filter using fqtrim −q 5 was then applied to the reads. Paired end reads that passing those filters were mapped to Homo sapiens (release 37) reference sequence (GRCh37/hg19); using BowTie2 and TopHat2. The raw read counts per gene were generated using the Rsubread package.

Check if the same lab product or an alternative is used in the 5 most similar protocols
A total of 12 samples were used for RNA-Seq analysis (three biological replicates from each of the MCF-7 isoforms and control cells). Sequencing libraries for the Illumina 2500 platform were created from the polyadenylated fraction of RNA from each cell line. mRNA was then isolated with Dyna1 oligo-dT beads (Invitrogen, Carlsbad CA) from 10μg of total RNA. The mRNA was randomly fragmented using the RNA fragmentation kit from Ambion. First-strand cDNA synthesis was performed using random primers and SuperScriptII reverse-transcriptase (Invitrogen, Carlsbad CA). This was followed by second-strand cDNA synthesis using DNA Polymerase I and RNase H (Invitrogen, Carlsbad CA). The Illumina adaptor was ligated to the ends of the double-stranded cDNA fragments and a 200bp size-selection of the final product was performed by gel-excision, following the Illumina-recommended protocol. Template molecules of 200bp cDNA with the adaptor attached were enriched by PCR to create the final library. Libraries were pooled and sequenced in two lanes on the Illumina HiSeq (2500) Sequencing System (Illumina, San Diego, CA) using 150bp reads at the New York Genome Center (New York, NY). Sequences in fastq format as well as normalized data files have been deposited into Gene Expression Omnibus (GEO)100 (link) (Project ID# GSE119449 entitled: ”Septin 9 over expression in MCF7”).

The feces of each animal were collected in a sterile EP tube and stored at −80°C for DNA extraction. Microbial genomic DNA was extracted from stool samples using the E.Z.N.A® Soil DNA Mini Kit (R6825, Omega Bio-Tek, Norcross, GA, United States), in accordance with the manufacturer’s protocols. The concentrations and purity of the resultant DNA samples were assessed using a NanoDrop™ system (NanoDrop, United States), following which the DNA was stored at −80°C for further tests.
The 16S rDNA gene was amplified using PCR with primers 16S-F (5′-CCTACGGGNGGCWGCAG-3′) and 16S-R (5′-GGACTACHVGGGTATCTAAT-3′), which target the V3–V4 region of the bacterial 16S rDNA gene. PCR reactions were performed in triplicate with Phusion® High-Fidelity PCR Master Mix (New England Biolabs) using template DNA. PCR products were purified using the AxyPrep™ DNA Gel Extraction Kit (Axygen Biosciences, Union City, CA, United States), according to the manufacturer’s instructions and quantified using ABI StepOnePlus™ Real-Time PCR System (Life Technologies, Foster City, CA, United States). The purified PCR products were pooled in an equimolar ratio and paired-end sequenced (2 × 250) on an Illumina HiSeq 2,500 Sequencing System (Illumina, San Diego, CA, United States) according to standard protocols (Caporaso et al., 2012 (link)).

Dental Epithelium RNA Extraction and Sequencing

Check if the same lab product or an alternative is used in the 5 most similar protocols
Animals (∼1-y-old adult MZ and LF males) were killed and immediately dissected for RNA extraction. A ribbon ∼1 mm × 10 mm of epithelium was removed labial to the outer row of teeth from the dentary of experimental animals using a no. 12 scalpel blade. The extraosseous soft tissue was removed from the entire jaw to reduce the risk of TBs containing epithelium carryover. The bone was then shaved down using a scalpel to expose the bony crypts, and intraosseous RT were extracted with fine forceps. Extracted tissue was quickly placed in RNAlater RNA Stabilization Reagent (Qiagen). Tissues were frozen in liquid nitrogen, homogenized using a mortar and pestle, and placed in TRIzol. Following standard chloroform extraction, RNeasy mini columns (Qiagen) were utilized to purify RNA for storage at −80 °C. Total RNA was quantified using Qubit (Molecular Probes) and quality analyzed using the Agilent 2100 Bioanalyzer System for RNA library preparation. RNA input was normalized to 1 µg, and libraries were prepared using the TruSeq Stranded mRNA Sample Prep Kit (Illumina-Kit A). Libraries were again quantified, quality assessed, and normalized for sequencing on the HiSeq 2500 Illumina Sequencing System.

Check if the same lab product or an alternative is used in the 5 most similar protocols
For chronic clenbuterol studies, lean WT mice (12-week-old males) consumed clenbuterol (30 mg/l) or regular drinking water for 5 days. Subsequently, quadriceps muscles were isolated from overnight (15 h) fasted or freely fed mice. Control and SKM-Rictor-KO mice were treated in the same fashion, but gastrocnemius muscle samples were collected from fed mice only. Total RNA was prepared from frozen tissues as described above. The RNA quality of all samples was analyzed on the Agilent 2100 bioanalyzer using the RNA 6000 Nano Chip. cDNA libraries were generated using New England Biolabs Ultra II kit following the manufacturer’s instructions. Indexed libraries of good quality (RNA Integrity Number > 8) were pooled and used for sequencing on a HiSeq 2500 Illumina Sequencing System. Single end 50 bp reads were mapped to mouse genome mm10. Analysis of differentially expressed genes was performed on the Genomatix Genome Analyzer using the DESeq2 (two-tailed Wald’s test) software package. Functional enrichment and pathway analysis of differentially expressed genes was performed using Qiagen IPA software and ToppGene Suite64 (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.
