(Submitter supplied) To assess which F. tularensis LVS transcripts are impacted by loss of bS21-2, we generated cells lacking the gene encoding bS21-2 (LVS ∆rpsU2). We then grew wild-type cells containing an empty vector (LVS pF), cells lacking bS21-2 with empty vector (LVS ∆rpsU2 pF), and cells lacking the native bS21-2 but ectopically expressing bS21-2 from a plasmid (LVS ∆rpsU2 pF-rpsU2-V). We isolated RNA from mid-log phase cells and analyzed by RNA-Seq.

(Submitter supplied) Francisella tularensis is a Gram-negative bacterium that causes a fatal human disease known as tularemia. The Centers for Disease Control have classified F. tularensis as Category A Tier-1 Select Agent. The virulence mechanisms of Francisella are not entirely understood. Francisella possesses very few transcription regulators, and most of these regulate the expression of genes involved in intracellular survival and virulence. more...

(Submitter supplied) Francisella tularensis, is an extremely virulent bacterium that can be transmitted naturally by blood sucking arthropods. During mammalian infection, F. tularensis infects numerous types of host cells, including erythrocytes. As erythrocytes do not undergo phagocytosis or endocytosis, it remains unknown how F. tularensis invades these cells. Furthermore, the consequence of inhabiting the intracellular space of red blood cells has not been determined. more...

(Submitter supplied) The facultative intracellular bacterium Francisella tularensis causes the zoonotic disease tularemia. F. tularensis resides within host macrophages in vivo and this ability is essential for pathogenesis. The transcription factor MglA is required for expression of several Francisella genes that are necessary for replication in macrophages and for virulence in mice. We hypothesized that identification of MglA-regulated genes in the Francisella genome by transcriptional profiling of wild-type and mglA mutant bacteria would lead to the discovery of new virulence factors utilized by F. more...

(Submitter supplied) Post-transcriptional gene regulation often involves RNA-binding proteins that modulate mRNA translation and/or stability either directly through protein-RNA interactions or indirectly by facilitating the annealing of small regulatory RNAs (sRNAs). The human pathogen Streptococcus pneumoniae D39 (pneumococcus) does not encode in its genome any homologs to RNA-binding proteins known to be involved in promoting sRNA stability and function, such as Hfq or ProQ, even though it contains genes for at least 112 sRNAs. more...

(Submitter supplied) These microarray studies are part of a larger study characterizing a deletion mutant of the putative transcriptional regulator IclR in Francisella tularensis LVS and SchuS4 strains. The microarrays were performed using RNA isolated from wild-type LVS and a LVS iclR deletion mutant after growing in Chamberlain?s defined media pH 6.3 to early mid-log phase. Results suggest that IclR affects expression of several genes after determining statistically significant differences by SAM.
