Sample GSM5577302 Query DataSets for GSM5577302
Status Public on Sep 06, 2022
Title WT_wo_Fe_5
Sample type SRA
 
Source name Bacteria
Organism Staphylococcus aureus subsp. aureus USA300
Characteristics bacterial strain: USA300_FPR3757
mutation in strain: None
treatment: None
Treatment protocol Cells were treated with 10 µM ferric ammonium sulfate or left untreated.
Growth protocol An individual bacterial colony was picked off a plate and grown overnight in tris minimal succinate (TMS) supplemented with 0.4 µM hemin. Cells were sub-cultured to a starting OD600 of 0.01 in iron restricted TMS supplemented with hemin and 1.5 µM transferrin. Cells were grown until mid-log phase at which point cells were treated with 10 µM ferric ammonium sulfate or left untreated for 1 hour before cells were harvested.
Extracted molecule total RNA
Extraction protocol To extract RNA from frozen S. aureus and hemB S. aureus, cell pellets were washed with TE buffer (pH 8.0) and re-suspended in a Tris-HCl mixture with 1 mg/mL lysostaphin (pH 7.5) to lyse for 1 hour at 37°C. RNA was extracted using an AurumTM Total RNA Mini Kit (BioRAD #7326820).
RNA samples were processed by the Microbial Genome Sequencing Center in Pittsburgh, PA. Ribosomal RNA (rRNA) was depleted (Qiagen FastSelect5S/16S/23S) and cDNA libraries were generated (Qiagen Total Stranded RNA). cDNA libraries were sequenced using NextSeq 550 using a 75bp x 8bp x 8bp setup.
 
Library strategy RNA-Seq

Library selection cDNA
Instrument model NextSeq 550
 
Data processing Sequencing reads were mapped to the reference S. aureus USA300 FPR3757 genome in Geneious Prime 2020.1.2 (https://www.geneious.com). Expression analysis and comparisons were performed using DESeq2 (Love MI et al Genome Biol 2014).
Genome_build: Staphylococcus aureus USA300_FPR3757
Supplementary_files_format_and_content: xlsx file format, contains RPKM values and calculated differential expression, fold change and p-values for every transcript.
Supplementary_files_format_and_content: The processed data file contains all replicates combined and the calculations of differential expression/fold changes are based on the comparison with the appropriate control group. Each sheet is named after the corresponding comparison.
