Sample GSM2631403 Query DataSets for GSM2631403
Status Public on Sep 01, 2018
Title Mock_3hr [miRNA]
Sample type SRA
 
Source name macrophage cell type
Organism Homo sapiens
Characteristics sample type: Mock control
time post infection: 3hr
molecule: rRNA-depleted RNA
Treatment protocol Primary human macrophage was separated from peripheral-blood leucocytes from healthy blood donors. The macrophages were seeded onto tissue culture plates in RPMI 1640 medium (Sigma-Aldrich) supplemented with 5% heat-inactivated autologous plasma.
Extracted molecule total RNA
Extraction protocol The macrophages were infected with H1N1 and H5N1 separately at a MOI of two. The cells were washed with warm culture medium and incubated in macrophage serum free medium (Invitrogen) supplemented with 0.6 mg/l penicillin and 60 mg/l streptomycin. The total RNA was extracted from cells at 1-, 3-, and 6-hr post-infection using the mirVana miRNA Isolation Kit (Ambion, Inc. TX, USA).
Small RNA library was prepared from rRNA-depleted RNA from 1 µg of total RNA. The 3’ adapter (5’-rAppAGATCGGAAGAGCGGTTCAGCAGGAATGCCGAG/3ddC/-3’, 3ddC represents a 3’ OH blocking group) that had an adenylated 5’-end and a ddC 3’-end was ligated to the 3’ end of the RNA using T4 RNA Ligase 2 (NEB, Ipswich, MA). The 5’ adapter (5’-rArCrArCrUrCrUrUrUrCrCrCrUrArCrArCrGrArCrGrCrUrCrUrUrCrCrGrArUrCrU-3’) ligation was performed using T4 RNA Ligase 1 (NEB, Ipswich, MA). The ligation product was used as template for cDNA synthesis using SuperScript II Reverse Transcriptase (Invitrogen) and an oligonucleotide with sequence complementary to 3’ adapter as RT primer (5’-CTCGGCATTCCTGCTGAACCGCTC–3’).
 
Library strategy miRNA-Seq
Library source transcriptomic
Library selection size fractionation
Instrument model Illumina Genome Analyzer II
 
Data processing Basecalls performed using Illumina pipeline version 1.3.
The small RNA sequencing reads were trimmed with low-quality ends and primer adapters. The trimmed high-quality reads were mapped to the miRBase database (http://www.mirbase.org/) using CLC Genomics Workbench. Due to the imperfect Dicer processing, a 5 bp overhang on the 5’- and 3’-end of mature/mature* miRNAs and 2 mismatches within the mature/mature* miRNAs were allowed. The abundance level of mature/mature* miRNA is measured with RPM (Reads mapped Per Million mappable reads), by normalizing to the total number of mapped reads for each sample. The relative abundance of miRNAs was evaluated by comparing the RPM between H1N1/H5N1 infection and mock infection and the significance was assessed with Z-score using Z-test.
Supplementary_files_format_and_content: Excel file containing the normalized miRNA expression (RPM) and differential expression values (including fold-change and Z-score).
