Three different datasets were used for evaluation in the present study, comprising selected Salmonella Montevideo [17] (link), Staphylococcus aureus CC398 [5] , and Salmonella Typhimurium DT104 [18] (link) from previous studies.
For S. Montevideo 12 closely related outbreak strains where sequenced once by US Food and Drug Administration using Roche Genome sequencer FLX system, Illumina MiSeq and Life Technologies Ion Torrent and made publicly available (Table S1), although only the MiSeq data was used in the original study [16] (link). The raw data were downloaded from the Sequence Read Archive (SRA). For Staphylococcus aureus CC398, the completely sequenced and annotated strain SO385 (AM990992.1) as well as four additional strains were selected from a previously published study [5] and sequenced twice using both MiSeq and Ion Torrent. HiSeq was used in the original study for sequencing. All the strains except for the reference strain were chosen from the same clade, named IIa1i in the original study. The strains are not epidemiologically related but have all been isolated from Danish Pigs and are shown to be closely related in the original study. For S. Typhimurium DT104 the reference strain NCTC 13348 (HF937208.1) and an additional three isolates from the same outbreak [18] (link) were sequenced twice on both MiSeq and Ion Torrent.
Genomic DNA (gDNA) was purified from the isolates using the Easy-DNA extraction kit (Invitrogen) and DNA concentrations determined using the Qubit dsDNA BR Assay Kit (Invitrogen). The isolates were sequenced twice on the MiSeq platform (Illumina) and Ion Torrent PGM (Life Technologies).
For Ion Torrent the isolates were sequenced following the manufacturer’s protocols for 200 bp gDNA fragment library preparation (Ion Xpress Plus gDNA and Amplicon Library 96 Preparation), template preparation (Ion OneTouch System), and sequencing (Ion PGM 200 Sequencing kit) using the 316 chip. For MiSeq the isolates chromosomal DNA of the isolates was used to create genomic libraries using the Nextera XT DNA sample preparation kit (Illumina, cat. No. FC-131-1024) and sequenced using v2, 2×250 bp chemistry on the Illumina MiSeq platform (Illumina, Inc., San Diego, CA).

Neutrophil granulocytes, CD4+ and CD8+ T-cells were isolated from donor blood using Histopaque density gradients and Ig-coupled beads against blood cell surface makers (pan T and CD4+ microbeads, Miltenyi Biotec). Nucleosome cores were prepared as previously described7 ; cells were snap-frozen and crushed to release chromatin, followed by micrococcal nuclease treatment. In vitro nucleosomes were prepared by combining human genomic DNA with recombinantly-derived histone octamers at an average ratio of 1 octamer per 850 bps. Unbound DNA was then digested using micrococcal nuclease. After digestion, reactions were stopped with EDTA, samples were treated with proteinase K, and nucleosome-bound DNA was extracted with phenol-chloroform and precipitated with ethanol (Supplementary methods). Purified DNA was size-selected (120–180 bp) on agarose to obtain mononucleosome cores, followed by sequencing library construction. RNA was isolated by homogenizing purified cells in Trizol, poly-A RNA was purified using Qiagen Oligotex kit and RNA-seq libraries were constructed using SOLiD Whole Transcriptome Analysis kit. All sequence data was obtained using SOLiD 35 bp protocol and aligned using the SOLiD pipeline against the human hg18 reference genome. Downstream analyses were all conducted using custom scripts (supplementary methods).

For the 500 pg and 100 pg E. coli (CC118) libraries and 10 pg human library (NA18507, Coriell), genomic DNA (in 1 μl volume) was incubated with 1 μl Nextera Illumina-compatible transposomes (Epicentre) at a 1 to 50 dilution (1 μl Nextera enzyme, 24 μl TE, 25 μl 100% glycerol), 1 μl 5× Nextera HMW buffer, and 2 μl nuclease-free water (Ambion). To avoid contamination, all dilutions and reaction preparation was carried out in a PCR hood. Reactions were incubated at 55°C for 5 min followed by addition of 25 μl 2× Nextera PCR buffer, 0.5 μl SYBR Green, 1 μl 50× Nextera primer cocktail, and 1 μl 0.5 μM barcode adaptor 2 (barcodes A6, A9, or A4 for 500 pg and 100 pg E. coli DNA, or 10 pg human DNA, respectively) and cycled under standard Nextera conditions in a MiniOpticon (Bio-Rad) real-time PCR thermocycler. Both reactions were removed after 20 cycles and cleaned up using Qiaquick MinElute columns, eluting in 20 μl EB. Libraries were run on a 6% Novex TBE PAGE gel (Invitrogen) for size verification and sequenced as barcoded spike-ins as per standard Illumina GAIIx protocol as a paired-end 101 bp (plus 9 bp barcode) run for E. coli libraries and a paired-end 36 bp (plus 9 bp barcode) run for human.

CKiD participants have casual BP measurements obtained in the right arm by auscultation at study entry (baseline), then annually thereafter. All participating sites have been provided the same aneroid sphygmomanometer (Mabis MedicKit 5, Mabis Healthcare, Waukegan, IL) by the CKiD Clinical Coordinating Centers (CCC's). The CCC's also provide standardized training and certification in the auscultatory BP measurement protocol described below to all study personnel responsible for casual BP measurement. Recertification in auscultatory BP measurement technique and calibration of each center's aneroid device takes place annually.
At each study visit, prior to BP determination, arm circumference is measured (in centimeters) with a plastic measuring tape at the midpoint of the upper arm between the amicron and olecranon and a cuff is then selected so that the length of the cuff bladder is equal to 80-100% of the arm circumference6 (link). Following cuff selection, the peak inflation pressure is determined by inflating the cuff to 60 mmHg and then gradually continuing to inflate in increments of 10 mmHg until the radial pulse is no longer felt – thereby determining the pulse obliteration pressure. An additional 30 mmHg is added to this value and recorded as the peak inflation pressure. The cuff is then inflated to this value for all BP measurements at that study visit.
After 5 minutes of rest, BP measurement begins. Participants are instructed to refrain from caffeine intake, smoking, and exercise at least one half hour prior to and until completion of BP measurement. They are also instructed to refrain from playing video games, using a cell phone, or other activities that may affect BP until all measurements are obtained. First, pulse is measured by palpation of the radial artery. Then three BP measurements at 30-second intervals are obtained by auscultation of the brachial artery, using the first Korotkoff sound for systolic BP (SBP) and the fifth Korotkoff sound for diastolic BP (DBP). The average of the 3 BP measurements is recorded as the participant's BP for the study visit. Participants' BP's so obtained at the baseline visit are included in the present study.

A total of 224 16S V3-V4 amplicon libraries (112 samples per each sampling site) were prepared following the Illumina metagenomic sequencing library construction workflow. The metagenome sequencing platform of the Illumina targeted a partial area containing the V3-V4 hypervariable region of the bacterial 16S rRNA gene. PCR for amplifying the target region was performed using the KAPA HiFi Hot Start Ready Mix (2×) (Roche, Mannheim, Germany), and a pair of 16S V3-V4 target-specific primer recommended by Illumina. The primer sequences were as follows: 16S 341F forward primer is 5’-TCGTCGGCAGCGTCAGATGTGTATAAGAGACAGCCTACGGGNGGCWGCAG-3“ and 16S 805 R reverse primer is 5”-GTCTCGTGGGCTCGGAGATGTGTATAAGAGACAGGACTACHVGGGTATCTAATCC-3’. After the PCR amplification, the purification process of all PCR amplicon products was conducted using the AMPure XP beads (Beckman Coulter, USA). Then, additional PCR amplification was performed using Nextera XT Index Kit (Illumina, USA), which included Illumina multiplexing dual index barcode and sequencing adapter sequence. The final PCR products were then purified once again using the AMPure XP beads. After the amplicon library construction, the 16S metagenome sequencing was performed using the paired-end 2 × 300 bp Illumina MiSeqTM protocol (Illumina Miseq, USA).

DNA samples were submitted for 16S rRNA gene sequencing at the Integrated Microbiome Resource (IMR) at Dalhousie University (Halifax, Canada). Variable regions V3-V4 of the bacterial 16S rRNA gene were amplified from all purified DNA samples using a set of primers 341F: 5'- CCTACGGGNGGCWGCAG -3' and 805R: 5'- GACTACHVGGGTATCTAATCC -3' [21 (link)] and sequenced on an Illumina MiSeq using paired-end 300 bp sequencing [22 , 23 (link)].
The 16S fusion primers were added to the multiplexed samples in equal amounts. Illumina Nextera adapters and barcodes were included in the fusion primers for dual-labeling at both ends of the amplicons. The reaction mixture of 25 µL contained 5 µL of 5 × HF buffer, 0.5 µL dNTPs (40 mM), 5 µL forward and 5 µL reverse primer (1 µM), 0.25 µL Phusion polymerase (2 U/µL; Thermo Scientific), 2 µL template and 7.25 µL water. The reaction conditions started with denaturation at 98 °C (30 s), followed by 30 cycles of 98 °C (10 s), 55 °C (30 s), and 72 °C (30 s). The final extension was performed for 4.5 min at 72 °C. The samples and negative controls were combined to form a single library and then applied to the Illumina MiSeq platform using 2 × 300 bp Pair-End v3 chemistry according to the manufacturer's protocol.

The GNAS active mutant was previously generated by site-directed mutagenesis of R201 to cysteine56 (link). GNASR201C cDNA was cloned into the pENTR backbone (pDONR221; ThermoFisher Scientific, 12536017) using the Gateway cloning BP reaction according to the manufacturer’s protocols (Invitrogen, 11789020). Activity of the GNASR201C active mutant was confirmed by cAMP-responsive element (CRE) luciferase assay (Dual-Glo Luciferase Assay System; Promega, E2920) or cAMP immunoassay (R&D Systems, KGE002B). The GNASR201C-pENTR vector was then recombined with the lentiviral vector pLVX-TetOne FLAG Puro (provided by the Krogan group, UCSF) using the Gateway LR reaction according to the manufacturer’s protocol (Invitrogen, 11791020). Viral particles were collected from HEK293T17 cells and concentrated by ultracentrifugation. Cells were transduced two times for 48 h and then selected with 1 μg ml–1 puromycin for 5 d. Expression of GNASR201C was induced by adding 1 μg ml–1 doxycycline.

For the library PCR step in combination with sample-specific barcoded primers, purified PCR products were shipped to BaseClear BV (Leiden, The Netherlands). PCR products were purified, checked on a Bioanalyzer (Agilent), and quantified. This was followed by multiplexing, clustering, and sequencing on an Illumina MiSeq with the paired-end (2×) 300 bp protocol and indexing. The sequencing run was analysed with the Illumina CASAVA pipeline (v1.8.3) by demultiplexing based on sample-specific barcodes. From the raw sequencing data, low quality of sequence reads, reads containing adaptor sequences, or PhiX control with an in-house filtering protocol were discarded and only “passing filter” reads were selected. On the remaining reads, we performed a quality assessment using the FASTQC quality control tool version 0.10.0. (http://www.bioinformatics.babraham.ac.uk/projects/fastqc/, accessed on 8 February 2022).
Sequences of the 16S rRNA gene were analysed using a workflow based on QIIME 1.8 [20 (link)]. On average, 23,918 (range 11,071–36,288) 16S rRNA gene sequences per sample were analysed. We performed operational taxonomic unit (OTU) clustering (open reference), taxonomic assignment and reference alignment with the pick_open_reference_otus.py workflow script of QIIME, using uclust as clustering method (97% identity) and GreenGenes v13.8 [21 ,22 (link),23 (link)] as reference database for taxonomic assignment. Reference-based chimera removal was performed with Uchime [24 (link)]. The RDP classifier version 2.2 was performed for taxonomic classification [25 (link)].
