SRX8745340: GSM4674721: Porphyromonas gingivalis WT inside THP-1 cells WT2; Porphyromonas gingivalis; RNA-Seq
1 ILLUMINA (Illumina HiSeq 2500) run: 71.6M spots, 14.5G bases, 5.4Gb downloads

Submitted by: NCBI (GEO)
Study: CRISPR-Cas protein Cas3 controls virulence in the oral pathogen Porphyromonas gingivalis.
show Abstracthide Abstract
Our results show that compared to wild type, a deletion mutant of the cas3 gene, an essential nuclease part of the class 1 type I CRISPR-Cas system, increases the virulence of P gingivalis. Overall design: we performed targeted deletion of cas3 to understand type I CRISPR-Cas systems and because it was among the most up-regulated CRISPR-Cas genes in our metatranscriptomic study (30). Using dual transcriptomic evaluations, coupled with cell and infection assays, this study demonstrates that Cas3 controls P. gingivalis virulence upon intracellular infection, but seems to have no role in virulence when growing in the planktonic phase

Library:
Instrument: Illumina HiSeq 2500
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: cDNA
Layout: PAIRED
Construction protocol: RNA Extraction. Total RNA was extracted from those samples using the mirVana RNA Isolation Kit (Life Technologies, Grand Island, NY). Samples were bead-beaten for 1 min at maximum speed with 300 μl of 0.1-mm zirconia-silica beads (BioSpec Products, Bartlesville, Okla.) in the mirVana lysis buffer. Bacterial ribosomal RNA was depleted using Ribo-Zero rRNA Removal Kits (Bacteria) (Epicentre, Madison, WI) following the manufacturer's protocol. For RNA processing for eukaryotic analysis, we used Dynabeads mRNA Purification Kit to isolate eukaryotic mRNA for transcriptome analysis. RNA libraries were prepared for sequencing using standard Illumina protocols. For RNA sequencing, Illumina adapter-specific primers were used to amplify and selectively enrich for the cDNA generated from enriched mRNA. Quantified libraries were pooled and sequenced using a HiSeq 2500 machine, 2x100 Flow-cell (Illumina). The Nextera XT kit was used to generate libraries from amplified DNA.
