Sample GSM3755977 Query DataSets for GSM3755977
Status Public on May 30, 2019
Title Inoculum 465
Sample type SRA
Source name Mid-log phase growth H. ducreyi
Organism [Haemophilus] ducreyi
Characteristics time: Day of infection
strain: 35000HP
tissue: N/A
Treatment protocol N/A
Growth protocol For samples 1-4, RNA was directly extracted from H. ducreyi-infected pustules on human volunteers. For samples 5-8, RNA was directly extracted from human wound-control sites. For samples 9-12, H. ducreyi was grown under GMP conditions to mid-log phase in a proteose peptone broth-based medium with 1% IsoVitaleX, 5% heat-inactivated fetal calf serum, and 50 ug/ml hemin and grown at 33°C for 5-6 hours.
Extracted molecule total RNA
Extraction protocol Biopsy samples immediately after collection and the extra inocula immediately after inoculation were placed in 2 mL RNAlater, incubated for 30 minutes at room temperature, and stored in RNAlater for one day at -80°C. Using a mini-Beadbeater (Biospec Products), we next homogenized the samples and extracted total RNA using a RNeasy Fibrous Tissue Mini kit according to manufacturer’s instructions along with addition of lysozyme (20 ug/mL) added at the proteinase K step. The RNA was treated twice with TURBO DNA-free DNase (Ambion) following manufacturer’s instructions. RNA concentrations and integrities were measured using a NanoPhotometer P330 (Implen). RNA samples were stored at -80°C until all samples were ready for sequencing. We removed 23S, 16S, and 5S rRNA before RNA-seq using the Ribo-Zero Gold rRNA Removal Kit (Epidemiology) (Epicentre Biotechnologies) following manufacturer’s instructions and confirmed their removal using the Agilent 2100 Bioanalyzer.
Twelve libraries (four mid-log phase growth H. ducreyi cultures, four infected sites, and four wounded sites) were constructed using the TruSeq Stranded Total RNA Library kit (Illumina) following manufacturer’s instructions.
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 4000
Description Sample 10
Data processing For the human samples, the sequence data were mapped to the human reference genome hg19 with STAR-2.5.2b
For the bacterial samples, the sequence data were mapped to the regerene genome Haemophilu ducreyi 35000hp ASM794v1 with bowtie 2 (version 2.3.2)
featureCounts (subread-1.6.0) was used to quantify gene expression (parameters applied: "“-s 2 –p –Q 10")
Differential expression analysis was performed using edgeR
Genome_build: Haemophilu ducreyi 35000hp reference genome ASM794v1 and human reference genome hg19
Supplementary_files_format_and_content: Two files (one for H. ducreyi and one for human) containing raw counts of sequencing reads
