The transcriptional response to low temperature is weakly conserved across Enterobacteriales

(Submitter supplied) Bacteria respond to changes in their external environment like temperature by changing the transcription of their genes, but we know little about how these regulatory patterns evolve. We used RNA-seq to study the transcriptional response of a shift from 37°C to 15°C in wild-type Escherichia coli, Salmonella enterica, Citrobacter rodentium, Enterobacter cloacae, Klebsiella pneumoniae, and Serratia marcescens, as well as ∆rpoS strains of E. more...

Prediction of Non-Coding sRNAs and Screening of Virulence-Related sRNAs of Salmonella Pullorum

(Submitter supplied) Purpose: Searching for sRNAs in Salmonella pullorum by RNA sequencing and exploring their functions.Methods: High-throughput sequencing of RNA extracted from Salmonella pullorum under normal growth conditions to detect newly discovered sRNAs, followed by experiments to verify their functions.Results: The proportion of Clean Reads of this sequencing was >65%, and the base Q30s were all above 85%, indicating that the sequencing quality is good and can be used for subsequent analysis. more...

Incremental increases in physiological fluid shear progressively alter pathogenic phenotypes and gene expression in multidrug resistant Salmonella

(Submitter supplied) The ability of bacteria to sense and respond to mechanical forces has important implications for pathogens during the in vivo infection process, as they experience wide fluid shear fluctuations in the host. However, relatively little is known about how mechanical forces encountered in the infected host drive microbial pathogenesis. We previously demonstrated an inverse relationship between fluid shear-induced responses of classic gastrointestinal disease-causing Salmonella Typhimurium (x3339) and systemic multidrug resistant (MDR) S. more...

Spermine-induced DNA methylation change in human macrophages

(Submitter supplied) Polyamines, crucial molecules involved in cell proliferation and growth, play a pivotal role in cancer development and progression. Within the tumor microenvironment, macrophages, key components of the immune system, exhibit a complex relationship with polyamines. Evidence suggests that polyamines can modulate macrophage polarization, influencing their functional phenotypes. Here, we detected the gene DNA methylation changes in spermine-stimulated human macrophages isolated from PBMCs and TAMs.

Integrated OMICs approach reveals energy metabolism pathway is vital for Salmonella Pullorum survival within the egg white

(Submitter supplied) Purpose: To elucidate the survival strategies in egg white of Salmonella Pullorum, a host-restricted pathogen with vertical transmission capability. Methods: The logarithmic-phase wild-type and Δfim mutant strains were inoculated into LB medium and egg white (final concentration 80%) and statically cultured at 42°C for 6 hours. RNA samples were then extracted for sequencing. Three biological replicates were carried out per sample. more...

Interplay of Salmonella enterica sv. Typhimurium and Bifidobacterium infantis during co-infection of gut epithelial cells

(Submitter supplied) The deposited microarray data were generated in a study that integrated the gene expression profiles and metabolic responses of Caco2 cells incubated with Bifidobacterium infantis subsp. infantis and Salmonella enterica subsp. enterica sv. Typhimurium. The aim of this study was to investigate the interaction of B. infantis, S. Typhimurium, and host cells (Caco2) in the course of infection to understand the molecular mechanics of probiotic-pathogen-host interactions.

Improved RNA stability estimation through Bayesian modeling reveals most bacterial transcripts have sub-minute half-lives [RIF-seq]

(Submitter supplied) RNA decay is a crucial mechanism for regulating gene expression in response to environmental stresses. In bacteria, RNA-binding proteins (RBPs) are known to be involved in post-transcriptional regulation, but their global impact on RNA half-lives has not been extensively studied. To shed light on the role of the major RBPs ProQ and CspC/E in maintaining RNA stability, we performed RNA sequencing of Salmonella enterica over a time course following treatment with the transcription initiation inhibitor rifampicin (RIF-seq) in the presence and absence of these RBPs. more...

Peeling back the layers of competitive exclusion using Salmonella as a model

(Submitter supplied) An ex vivo system was developed to monitor Salmonella growth, virulence (SPI1 expression) and gene expression (measured by microarray) in response to the permissive and exclusive communities. Yellow fluorescent protein (yfp) and cyan fluorescent protein (cfp) variants were fused to the rrn growth-dependent promoter and the hilA operon (SPI-1 cell invasion locus), respectively, in Salmonella. Fluorescence associated with the YFP and CFP reporters was used to monitor Salmonella growth and SPI1 virulence gene expression in co-culture with cecal communities ex vivo. more...
