Candida albicans (DAY286 yeast) extracellular vesicle and whole cell lysate proteomes

ABSTRACT: We performed proteomic analysis of extracellular vesicles (EVs) and whole cell lysates (WCL) isolated from the same liquid culture (strain = DAY286, n = 3). This data set is the first label-free quantitative comparative study of the proteins in C. albicans EVs and their parent planktonic (yeast-form) cells. We identified proteins enriched in EVs versus WCL by comparing their LFQ intensities across all samples. After linking these results with EV enrichment data from other strains, we proposed a suite of putative EV marker proteins which were useful for multiple C. albicans strains and morphologies.

<b>Background:</b> Fungal extracellular vesicles (EVs) have been implicated in host-pathogen and pathogen-pathogen communication in some fungal diseases. In depth research into fungal EVs has been hindered by the lack of specific protein markers such as those found in mammalian EVs that have enabled sophisticated isolation and analysis techniques. Despite their role in fungal EV biogenesis, ESCRT proteins such as Vps23 (Tsg101) and Bro1 (ALIX) are not present as fungal EV cargo. Furthermore, tet ...[more]

Candida albicans (ATCC90028 and ATCC10231 yeast) extracellular vesicle and whole cell lysate proteomes

Project description:We performed proteomic analysis of extracellular vesicles (EVs) and whole cell lysates (WCL) isolated from the same liquid culture. This was implemented for two different C. albicans strains, ATCC90028 (n = 3) and ATCC10231 (n = 3). This data set is the first label-free quantitative comparative study of the proteins in C. albicans EVs and their parent planktonic (yeast-form) cells. We identified proteins enriched in EVs versus WCL by comparing their LFQ intensities across all samples. After linking these results with EV enrichment data from other strains, we proposed a suite of putative EV marker proteins which were useful for multiple C. albicans strains and morphologies.

Candida albicans (DAY286 biofilm) extracellular vesicle and whole cell lysate proteomes

Project description:We performed proteomic analysis of extracellular vesicles (EVs) and whole cell lysates (WCL) isolated from the same biofilm (strain = DAY286, n = 5). We identified proteins enriched in EVs versus WCL by comparing their LFQ intensities across all samples. After linking these results with EV enrichment data from other strains, we proposed a suite of putative EV marker proteins which were useful for multiple C. albicans strains and morphologies.

Comparative microarray analysis of NaV1.8-expressing DRG neurons and cold-sensitive non-NaV1.8-expressing DRG neurons

Project description:The vast majority of cold sensitive DRG neurons from mice do not express the voltage-gated sodium channel NaV1.8. Therefore, we aimed to compare the molecular profiles of NaV1.8 and non-NaV1.8-expressing neurons using microarray analysis. Fluorescent activated cell sorting was performed at 4 degrees centigrade on acutely dissociated DRG neurons from mice expressing NaV1.8-Cre, Pirt-GCaMP3 and a Cre-dependent global reporter (td tomato). NaV1.8-expressing neurons were sorted based on their reporter fluorescence (td tomato; red) and putative cold sensing neurons were sorted based on their GCaMP3 fluorescence at 4 degrees centigrade and absence of Cre-dependent reporter fluorescence. A total of three mice were used (samples one, two and three) with GCaMP3 only and NaV1.8-expressing neurons forming two relative populations within each sample (eg. GC3 one is the experimental counterpart of Tom one).

Proteome of extracellular vesicles from the filamentous fungal pathogen Fusarium graminearum

Project description:We performed a comparative study to determine the proteome of extracellular vesicles (EVs) from the cereal pathogen Fusarium graminearum (Fgr), recovered from in vitro cultures. Label-free quantitative proteomics was used to find significant enrichment of proteins between EV samples, the secretome (secreted-soluble proteins) and the cell lysate. Our results show that some proteins were exclusive to EVs and were upregulated compared to the secretome or cell lysate.

Microarray data of the subventricular zone and hippocampal tissue from mice exposed to room air or hyperoxia during the neonatal period

Project description:This experiment aimed to investigate the differences in the transcriptional profile of the neurogenic niche regions of mouse pups that were raised in room air verses mouse pups that were exposed to hyperoxia during the neonatal period. Pups were housed in room air or hyperoxia (85% O2) from P0 to P14. Brain tissue (the subventricular zone and the hippocampus) was collected at P14 and 12 months of age. RNA was extracted from the brain tissue and the microarray labelling, hybridization, and scanning was conducted by the Génome Québec Innovation Centre (Montréal, Canada).

Microarray of neural progenitor cells from neonatal lung injury mice treated with placebo or umbilical-cord mesenchymal stromal cell extracellular vesicles or untreated, as well as age-matched control mice

Project description:The purpose of this experiment was to determine the transcriptional differences between neural progenitor cells from neonatal lung injury mice vs. control mice, as well as neonatal lung injury mice treated with umbilical-cord mesenchymal stromal cell extracellular vesicles vs. neonatal lung injury mice treated with placebo (PBS). Neural progenitor cells were isolated from the subventricular zone and hippocampus and cultured for 2 consecutive neurosphere assays. RNA was then extracted from the cells, and the microarray labelling, hybridization, and scanning was conducted by the Génome Québec Innovation Centre (Montréal, Canada).

Fusarium oxysporum f. sp. vasinfectum (UP000030701) extracellular vesicle, secretome, and cell lysate proteomes

Project description:We performed a comparative study to determine the proteome of extracellular vesicles (EVs) from the cotton pathogen Fusarium oxysporum f. sp. vasinfectum (Fov), recovered from two growth conditions in vitro. Label-free quantitative protemics was used to find significant enrichment of proteins between EV samples, the secretome (secreted-soluble proteins) and the cell lysate. Our results show that some proteins were exclusive to EVs and were upregulated compared to the secretome or cell lysate.

Gene expression profiling of human whole-blood samples before and after the administration of recombinant human erythropoietin

Project description:As part of cross-platform comparisons of microarray and RNA-seq, this current experiment using the Affymetrix Human Transcriptome Array 2.0 aimed to quantify gene-level expression in subjects administered recombinant human erythropoietin over a 10-week protocol for the identification of gene signatures of blood doping. These results were compared to results obtained from other gene expression quantification platforms using the same experimental cohort, including the Illumina HumanHT-12v4 Expression BeadChips (archived in ArrayExpression; E-MTAB-2874), Illumina NextSeq 500 and MGI DNBSEQ-G400RS.

Crosstalk between the effects of extracellular vesicles (Evs) and TNF on U937 human monocyte cell line

Project description:Under physiological conditions, extracellular vesicles (EVs) are present simultaneously in the extracellular compartment together with cytokines. Thus, we hypothesized that EVs in combination with cytokines induce different responses of monocyte cells compared to EVs or cytokines alone. Human monocyte U937 cells were incubated with EV-containing or EV-free CCRF human T-cell supernatant, with or without the addition of TNF. U937 cells cultured in EV-free supernatant, supernatant containing CCRF t-cell derived EVs, TNF or both. Each treatment option was measured in 3 replicates.
