Cord blood buffy coat DNA methylation is comparable to whole cord blood methylation

Project description:Cord blood DNA methylation is associated with numerous health outcomes and environmental exposures. Whole cord blood DNA reflects all nucleated blood cell types, while centrifuging whole blood separates red blood cells by generating a white blood cell buffy coat. Both sample types are used in DNA methylation studies. Cell types have unique methylation patterns and processing can impact cell distributions, which may influence comparability. To evaluate differences in cell composition and DNA methylation between buffy coat and whole cord blood samples, cord blood DNA methylation was measured with the Infinium EPIC BeadChip (Illumina) in 8 individuals, each contributing buffy coat and whole blood samples.

Single cell RNAseq reveal covid19 patient immune response

Project description:Eighteen patients admitted to CSMC and diagnosed with COVID19 by RT-PCR were stratified into COVID19 mild/moderate, severe, and recovery groups (n=5-6/group). Venous blood was collected into EDTA coated tubes and centrifuged to separate plasma and buffy coat. Plasma was collected and frozen at -80C, and the buffy coat was collected into cryo-preservation media and frozen at -80C. Recovered cells are sorted for live-dead staining, then fixed with methanol. Fixed single cells were further captured using 10x chromium Next GEM 3 prime v3.1 kit. Two patients samples from the same group were mixed, captured and sequenced together.

Smaller stature in childhood following assisted reproductive technologies (ART) is not explained by parental or gestational factors, early childhood environment, or fetal DNA methylation [GUSTO_buffy_coat]

Project description:As part of an investigation on contributors to offspring size following assisted reproduction, we investigated maternal mid-/late-pregnancy peripheral blood buffy coat DNA methylation at 240 CpGs previously associated with maternal pregnancy morbidity or offspring growth across various tissues. Illumina Infinium MethylationEPIC BeadChip was used to obtain DNA methylation profiles in previously frozen buffy coat samples from 70 women who conceived via assisted reproduction technologies and gave live births and 845 women who spotaneously conceived and gave live births.

Analysis of the impact of cellular miRNA signatures on the profiles of circulating miRNA biomarkers (fractionation data)

Project description:Circulating miRNAs are an emerging class of biomarkers correlating their specific expression patterns to disease states. A considerable proportion of hematopoietically-derived miRNAs are present in plasma with the ability to confound the signature of true circulating miRNA species. We use microarray analysis to catalogue a list of 313 haemotopoetic miRNAs and analyze expression profiles of cell-free miRNAs in individual plasma fractions after calibrating for cellular miRNA signals. Comprehensive global maps of bona fide circulating miRNA species are presented, and inter-individual variability and gender-specific expression is explored in populations of healthy individuals. Healthy Caucasian individuals were used to segregate blood into 8 subfractions: white blood cells (WBC)/buffy coat, leukocytes, red blood cells (red blood cells (RBC)), cloudy supernatant (CS), supernatant 1 (S1), supernatant 2 (S2), pellet 1 (P1) and pellet 2 (P2) through differential centrifugation to understand the proportion of cellular miRNAs in each category.

Genome-wide study of the effect of blood collection tubes on the cell-free DNA methylome

Project description:In this study, we evaluated the effect of preservation agent on the effect of the methylation pattern of cell-free DNA. The methylation pattern was assessed with cell-free reduced representation sequencing (cf-RRBS). Blood was drawn from three healthy individuals (male and females between 24 and 50 years old). 15 tubes were drawn per healthy volunteer: 3x BD Vacutainer K2E EDTA spray tubes (REF 367525), 3x Streck Cell-Free DNA BCT tubes (catalogue number 218962), 3x PAXgene Blood ccfDNA tubes (catalogue number 768115), 3x Roche Cell-Free DNA Collection tubes (catalogue number 07785674001) and 3x Biomatrica LBgard blood tubes (SKU 68021-001), resulting in 45 samples in total. All 45 samples were sequenced on a NovaSeq6000. Samples are given as bismark coverage files (GRCh37).

cfDNA methylation data of longitudinally collected blood plasma samples from patients with esophageal adenocarcinoma

Project description:This study aimed to evaluate the cost-effective and genome-wide cell-free reduced representation bisulfite sequencing (cfRRBS) method combined with computational deconvolution for effective disease monitoring in patients with esophageal adenocarcinoma (EAC). cfDNA methylation profiling with cfRRBS was performed on 162 blood plasma samples from 33 EAC cancer patients and 28 blood plasma samples from 20 healthy donors. In addition, for reproducibility testing purposes of the method, 9 plasma samples were re-prepped (library was re-made) and re-sequenced once (n=9) or twice (n=1). As a reference for the data deconvolution cfRRBS was performed on 7 EAC tumor tissue (FFPE) samples.
