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

ABSTRACT: 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).

The Extracellular RNA Quality Control (exRNAQC) study: Small RNA sequencing of blood collection tube study (exRNAQC013)

Project description:To evaluate the impact of blood collection tubes on extracellular RNA (exRNA) sequencing, 10 different blood collection tubes were compared by applying Small RNA sequencing (Illumina) to exRNA from human healthy donor plasma or serum. Three time spans between blood draw and downstream processing were evaluated for each of the tubes. Preservation tubes were processed immediately upon blood collection (T0), after 24 hours (T24), or after 72 hours (T72). Non-preservation plasma and serum tubes were processed immediately upon blood collection (T0), after 4 hours (T4), or after 16 hours (T16). Due to donor privacy concerns the raw data for this study have been submitted to the controlled-access archive EGA under the accession EGAS00001005263.

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.

Identification of novel and already known altered micoRNAs lead to a deeper understanding of the development of type 1 diabetes mellitus

Project description:Type 1 diabetes is a chronic autoimmune disease which results in inefficient regulation of glucose homeostasis and can lead to different vascular comorbidities through life. Next generation sequencing analysis was firstly performed to identify miRNAs that were differentially expressed between groups (20 patients vs. 10 controls). The aim of this study is to analyze the expression profile of circulating miRNAs in the plasma of adult patients with well-established type 1 diabetes and with no associated comorbidities, compared to healthy subjects, to identify miRNAs that are specific from diabetes pathology, and to assess pathways and biological processes related to the state of this disease.

Extensive tumour profiling in primary neuroendocrine breast cancer cases as a role model for personalized treatment in rare and aggressive cancer types

Project description:Especially in rare cancer types such as neuroendocrine breast cancer (NEBC), it is important to analyze the individual characteristics more deeply. NEBC itself is a highly heterogenous disease and no guidelines exist to date. To add another layer of information to understand the tumor characteristics better,we analyzed mRNA from two cancer patients to determine the signal transduction pathways and to identify possible contributions to a beneficial treatment. Among other procedures plasma samples (2 ml) from EDTA tubes were centrifuged at 16000g for 10 min at 4 °C and filtered via a 0.45 µm membrane to remove larger vesicles. The filtrate was used for the extraction of total exosomal RNA using an ExoRNeasy serum/plasma kit (QIAGEN, Germantown, USA) according to the manufacturer’s protocol. Purified exosomal RNA was quantified using an miRNA Qubit assay (Life Technologies, Carlsad, USA). The Ion AmpliSeq™ Transcriptome Human Gene Expression Research Panel was used to determine the expression of 20,802 genes including 18,574 coding genes and 2228 non-coding genes based on University of California Santa Cruz (UCSC) hg19 annotation.

Fetal transcripts in maternal blood

Project description:The discovery of fetal mRNA transcripts in maternal circulation holds great promise for noninvasive prenatal diagnosis. To identify potential fetal biomarkers, we studied whole blood and plasma transcripts common to term pregnant women and their newborns but reduced or absent in the postpartum mothers. In whole blood, 157 potentially-fetal transcripts were identified. RT-PCR confirmed the presence of specific transcripts, SNP analysis confirmed the presence of fetal transcripts in maternal circulation. Comparison of whole blood and plasma samples from the same women suggested that placental genes are more easily detected in plasma. We conclude that fetal and placental mRNA circulates in the blood of pregnant women. [I] We profiled whole antepartum (A), postpartum (P), and umbilical cord (U) blood samples from each of 9 mothers and their 10 newborns (1 set of twins, denoted as a and b after the sample names). [II] We also profiled plasma samples (A, P, and U) from three of those mothers to allow for a direct comparison between blood and plasma.
