Sample GSM7118764 Query DataSets for GSM7118764
Status Public on Mar 28, 2023
Title WB, post-COVID-19, sequela MC1_71
Sample type SRA
 
Source name Whole blood
Organism Homo sapiens
Characteristics tissue: Whole blood
age: 56
Sex: Male
dlco (%_of_predicted): 52.9
Treatment protocol Venous blood samples were collected in Tempus TM blood RNA tubes by venipuncture after a night of fasting and before beginning pulmonary evaluation. Blood samples were stored at -80 °C for future analysis.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted from 200 μL of preprocessed whole blood with the Maxwell® RSC simply RNA Blood Kit in combination with the Maxwell® RSC Instruments.
RNA was isolated from 1 μg of total RNA using Illumina´s Ribo-zero plus rRNA depletion kit. The RNA was fragmented into approximately 200 base pair (bp) pieces by using divalent cations under elevated temperature. Reverse transcriptase and random primers were used to generate first strand cDNA from cleaved RNA fragments. DNA polymerase I and RNase H were used to obtain the second strand. Double-stranded cDNA fragments were end-repaired by Klenow DNA polymerase and T4 DNA. cDNA was phosphorylated by T4 polynucleotide kinase and ligated to Illumina indexing adapters. Adapter-tagged libraries were amplified by using 15 cycles of PCR with DNA polymerase. Validation and quantification were performed using electrophoresis and qPCR. Pools of six indexed libraries were mixed at equimolar ratios to yield a total oligonucleotide mixture concentration of 10 nM.

Description WB, post-COVID-19, sequela
MC1_71
Data processing Raw sequence data in fastq format were processed using a sequential workflow:
(i) data were cleaned of adapters and low-quality sequences using TrimGalore v0.6.6 (https://www.bioinformatics.babraham.ac.uk/projects/trim_galore/ accessed date April 1st, 2021).
(ii) reads were mapped to the reference genome (GRCh38.p12) by the aligner STAR (https://github.com/alexdobin/STAR).
(iii) mapped reads were counted using FeatureCounts (http://subread.sourceforge.net/ accessed date April 1st, 2021).
(iv) global distance analysis and normalization of reads were performed through DESeq2.
(v) differential expression analysis were performed using two different protocols derived from the R package SARTools: DESeq2 y EdgeR.
Assembly: GRCh38.p12
