Project description:To evaluate the impact of the RNA purification method on extracellular RNA (exRNA) sequencing, 8 different RNA purification kits were compared by applying Small RNA sequencing (Illumina) to exRNA from human healthy donor plasma. Minimum and maximum plasma input volumes recommended by the manufacturers were tested in triplicate. Due to donor privacy concerns the raw data for this study have been submitted to the controlled-access archive EGA under the accession EGAS00001005263.
Project description:Purpose: The aim of this study is to compare the plasma miRNA profile between healthy control and sepsis patients Methods: Plasma from healthy control and sepsis patients were used in the study. Total RNA was isolated from equal volume of plasma using Trizol LS. NGS cDNA libraries were prepared using Norgen Biotek Small RNA Library Prep Kit. Library quality was validated prior to sequencing on an Illumina NextSeq 500 platform.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are to compare the small RNA profile of healthy and myeloma plasma cells derived from non cancer donors and newly diagnosed myeloma patients Methods: Plasma Cell small RNA profiles of 3 healthy plasma cells and 3 newly diagnosed myeloma patients were generated by deep sequencing, using Illumina GAIIx. Conclusions: Our study represents the first detailed analysis of small RNA sequencing in plasma cells. The optimized data analysis workflows reported here should provide a framework for comparative investigations of expression profiles. Our results show that NGS offers a comprehensive quantitative and qualitative evaluation of small RNA content within the healthy and myeloma plasma cells.
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.

Project description:In the past decades, the incidence of esophageal adenocarcinoma has increased dramatically in Western populations. Better understanding of disease etiology along with the identification of novel prognostic and predictive biomarkers are urgently needed to improve the dismal survival probabilities. Here, we performed comprehensive RNA (both coding and non-coding) profiling in various samples from 17 patients diagnosed with esophageal adenocarcinoma, high-grade dysplastic or non-dysplastic Barrett’s esophagus. Per patient, a blood plasma sample, and a healthy esophageal and disease tissue sample were included. In total, this comprehensive dataset consists of 102 RNA-seq libraries from 51 samples. The raw data for this study have been deposited to the controlled access archive EGA under submission EGAS00001004939.
Project description:RNA sequency was performed on maternal plasma from pregnant women carrying nsCLP foetuses or healthy foetuses. The aim of this study is to explore potential promising biomarkers for diagnosing nsCLP.
Project description:In our study, we generated and sequenced small RNA libraries from blood plasma samples. These samples were obtained from patients undergoing colonoscopy and are balanced for age, sex, and self-identified ancestry. From the sequencing data, we derived small-RNA feature counts and performed an analysis for differential expression between patients with and without colorectal adenoma. We found numerous significant associations, including hsa-miR-335-5p and a RNA fragment of the theoretical transcript, AK126744.
Project description:High-throughput sequencing of the miRNAs present in plasma of COVID-19 patients at an early stage of the disease including non-SARS-CoV2 infected patients. This study allowed us to identify and functionally characterize human miRNAs associated with a worse evolution of the disease and a greater mortality. Samples were collected at hospital entry or within the first days after hospitalization and before treatment with immunotherapy for IL6 (e.g. Tocilizumab), interferon beta, corticoids and ribavirin, among others. Plasma samples were obtained from peripheral blood extracted in EDTA tubes after centrifugation. Total RNA, including small RNAs, was isolated from 400μl of plasma with the miRNeasy Serum Plasma Advanced kit (Qiagen). RNA quality and quantity were evaluated by the Bioanalyzer 2100 with Agilent RNA 6000 Nano Kit.
