    PCR products of QIAcube-extracted mouse DNA+/−digestion with HaeII. QIAcube extraction apparently results in mostly covalently closed supercoiled mtDNA, which limits primer access. HaeII digestion near the D-Loop (bp ~2,607) greatly increases amplification of the large target. Raw fluorescence values of Lmito ( a ) and Smito ( b ) and hence lesion frequencies ( c ) are affected by digestion. Lesion frequencies represent the decrease in amplification of the large mitochondrial fragment normalized to the small fragment. Data represent the mean+/−SD of two biological samples. Net fluorescence: Picogreen fluorescence of the PCR product minus a “no-template” control

    Sample collection, DNA isolation and shotgun metagenomic sequencing. ( A ) (I.) Sample collection: Vitreous body (intraocular body fluid) was collected through vitrectomy from 14 patients with endophthalmitis following cataract surgery (n = 7) and intravitreal injection (n = 7). As control, vitreous was collected from 7 patients without postoperative endophthalmitis during macula hole surgery. Six aliquots (3 sample pairs) were obtained from balanced salt solution (BSS) that is infused into the eye during vitrectomy. Three aliquots were collected from separate BSS bottles (BSS-B) and the second set of aliquots was collected from the vitrectomy surgical system (BSS-S) after it had passed through the vitrectomy infusion line, respectively. The samples were examined using (II.) Cultivation-based analyses and (III.) DNA isolation (2 methods) Metagenomic shotgun sequencing, including the examination of DNA extraction (blank) controls. A total of 62 samples were sequenced using Illumina MiSeq sequencing technology. ( B ) More details to steps (II.) and (III.): (II.) Cultivation-based analyses: Aliquots of the vitreous body fluid and balanced salt solution samples were subjected to cultivation-based analyses separately at the hospital and research laboratories. Obtained isolates were analyzed using mass spectrometry and whole genome sequencing. (III.) DNA isolation Metagenomic shotgun sequencing: Samples were extracted using two DNA isolation procedures: QIAamp DNA Mini Kit (QIA) and QIAamp UCP Pathogen Mini kit (UCP). A DNA extraction (blank) control was included at each round of DNA isolation, i.e. one DNA extraction control for 12–14 samples in total per extraction round (more vitreous samples were extracted than analyzed in this study). To verify the presence of the main microorganisms detected in the metagenomics analysis, the shotgun metagenomics reads were mapped to the genome assemblies of the isolates obtained from the vitreous samples. Not displayed here is the mapping of metagenomic shotgun reads to microbial reference genomes in the database (Provided in Fig. 4 ). As an additional verification, PCR analyses were carried out to detect the presence of the most abundant microorganisms in the vitreous samples using organism-specific primer sets.

Bacterial isolates were obtained at the hospital laboratory (1 st cultivation) from vitreous from endophthalmitis patients following cataract surgery (C1-7) and intravitreal injection (I1-7) and the taxonomic affiliation of the isolates were determined by MALDI-TOF mass spectrometry (MS). Vitreous was analyzed through metagenomics at the research laboratory using two DNA isolation methods (QIAamp DNA Mini Kit, QIA; QIAamp UCP Pathogen Mini kit, UCP) and the taxonomic affiliation of reads was determined. The detected amount of human DNA sequences in percent (%) is provided in the first column of the Metagenomics tab. In the horizontal bar charts, the taxonomic identity and relative fraction of microbial reads for the most abundant identified organisms based on the Kraken + Bracken analysis is indicated for both DNA isolation methods. The read counts for the most abundant organism according to the Kraken + Bracken (all reads) and BLASTN (forward read) analyses are indicated to the right. The read counts for the most abundant organisms per sample as determined by Kraken, Bracken and BLASTn analyses are available through figshare at https://figshare.com/s/5feabfad1d8c495bf7a3 . Bacterial isolates for some samples were obtained in a second round of cultivation at the research laboratory (2 nd cultivation) and one representative per colony morphotype per vitreous sample was subjected to MS and whole genome sequencing (WGS). The taxonomic affiliation of isolates was determined through classification of assembled genomes using a k-mer based approach and genomic MLST, and antibiotic resistance genes were identified using ResFinder. Furthermore, metagenomic assemblies were generated from the shotgun metagenomic reads and analyzed with regards to taxonomic affiliation and selected functional characteristics (Supplementary Table S6 ).

    The LSC epigenetic signature is associated with overall survival in human AML. ( a ) TCGA samples were classified as LSC like or Blast like based on DNA methylation alone by generating methylation profiles of the LSC and Blast populations, and then calculating scores of each sample based on the probability of being closer to either LSC or Blast. Kaplan–Meier survival analysis was then applied to these groups as indicated. Statistical significance was determined by the log-rank test ( n =192; 93 LSC-like and 99 Blast-like patients). ( b – e ) Expression of the LSC epigenetic signature genes was combined to create an LSC score, which was then calculated in AML samples. The first principal component of genes in the LSC signature was computed, and patients were stratified as ‘high' or ‘low' relative to its median value in four independent cohorts including TCGA ( n =182; 91 high-score and 91 low-score patients), ( b ) Metzeler et al .

    Journal: eLife

    doi: 10.7554/eLife.54879

    Proposed model for cell-specific epigenetic modifications in a synaptic calcium ion channel gene controls cell-specific splicing. In naïve animals, in most neurons, Cacna1b e37a locus is hypermethylated (5-mC) and CTCF is presumed not to bind this locus based on our results in the DRG-derived F11 cell line. During splicing, e37a is skipped and Cacna1b mRNAs include e37b. In contrast, in Trpv1 -lineage neurons, Cacna1b e37a locus is hypomethylated and is presumed to be permissive for CTCF binding. Hypomethylation promotes e37a inclusion and both Cacna1b e37a and e37b mRNAs are expressed. E37a confers strong sensitivity to the Ca V 2.2 channel to inhibition by μ-opioid receptors (μOR; [ Andrade et al., 2010 ; Raingo et al., 2007 ]). Morphine is more effective at inhibiting e37a-containing Ca V 2.2 channels. After peripheral nerve injury that results in pathological pain, methylation level of Cacna1b e37a locus is increased, CTCF binding is presumed to be impaired, and Cacna1b e37a mRNA levels are decreased. This disrupted splicing pattern is associated with reduced efficacy of morphine in vivo ( Jiang et al., 2013 ).

Schematic of the inoculating FIV LTR sequence (FIV-C pgmr) including the genomic location of all mutations discovered overtime in PBMC or in CD4 T cells before and after ex vivo reactivation in all 4 FIV-infected cats. The single SNP identified in the U5 region of the inoculating virus is depicted by a black box. Mutations within gray boxes represent those found in cell-associated vRNA; unboxed mutations were discovered in proviral DNA. The location of various transcription factor binding sites in the U3 region are denoted by unshaded boxes. Mutations denoted by asterisks have been previously cloned into expression constructs, and their promoter activity has been assessed. The TATA box is underlined.

    Quantification of pBR322 plasmid copy number by digital droplet PCR. E . coli DH5α total DNA isolated by the bead beating method (A) and the QIAamp DNA mini kit (B), from two independent bacterial cultures in a logarithmic growth phase (Experiment 1 and 2), served as a template for the bla and dxs ddPCR amplification with the use of primer set A ( Table 1A ). Each experiment was run in two replicates (bla1, bla2 and dxs1, dxs2). Error bars indicate the 95% confidence limits as determined from the Poisson distribution. (C) Columns A01 and E01 represents single wells of ~ 20,000 droplets after ddPCR amplification of bla and dxs , respectively. (D) Estimated pBR322 copy number by digital droplet PCR. The plasmid copy number of pBR322 was calculated by dividing the copy number of bla by the copy number of dxs . Average PCN from four measurements was determined to be 20.5 for QIA and 7.3 for the bead-beating method.
