Dissecting the sharp response of a canonical developmental enhancer reveals multiple sources of cooperativity. [PDF]

, 2019
Developmental enhancers integrate graded concentrations of transcription factors (TFs) to create sharp gene expression boundaries. Here we examine the hunchback P2 (HbP2) enhancer which drives a sharp expression pattern in the Drosophila blastoderm ...

Integrated signaling pathway and gene expression regulatory model to dissect dynamics of Escherichia coli challenged mammary epithelial cells [PDF]

, 2014
Cells transform external stimuli, through the activation of signaling pathways, which in turn activate gene regulatory networks, in gene expression. As more omics data are generated from experiments, eliciting the integrated relationship between the ...

Expression profiles of XIK1 and OsSWEET14 genes in parental and back‐ crossing rice lines after Xanthomonas oryzae pv. oryzae infection

Indonesian Journal of Biotechnology
Oryza sativa L. ssp. indica (RD47 cultivar) is a major commercial rice variety known for its highly stable yields. However, it is highly susceptible to bacterial blight disease caused by Xanthomonas oryzae pv. oryzae (Xoo).

A Prophage-Encoded Small RNA Controls Metabolism and Cell Division in Escherichia coli

mSystems, 2016
Hundreds of small RNAs (sRNAs) have been identified in diverse bacterial species, and while the functions of most remain unknown, some regulate key processes, particularly stress responses.

Nitric oxide mediates antimicrobial peptide gene expression by activating eicosanoid signaling. [PDF]

PLoS ONE, 2018
Nitric oxide (NO) mediates both cellular and humoral immune responses in insects. Its mediation of cellular immune responses uses eicosanoids as a downstream signal.

TetR Regulated in vivo Repression Technology to Identify Conditional Gene Silencing in Genetically Engineerable Bacteria Using Vibrio cholerae Murine Infections as Model System

Bio-Protocol, 2020
Investigation of bacterial gene regulation upon environmental changes is still a challenging task. For example, Vibrio cholerae, a pathogen of the human gastrointestinal tract, faces diverse transient conditions in different compartments upon oral ...

Identification of the RNA-binding domain-containing protein RbpA that acts as a global regulator of the pathogenicity of Streptococcus suis serotype 2

Virulence, 2022
Streptococcus suis serotype 2 (SS2), an emerging zoonotic pathogen, causes swine diseases and human cases of streptococcal toxic shock syndrome. RNA-binding proteins (RBPs) can modulate gene expression through post-transcriptional regulation.

Fight or flight? – Flight increases immune gene expression but does not help to fight an infection [PDF]

, 2017
Flight represents a key trait in most insects, being energetically extremely demanding, yet often necessary for foraging and reproduction. Additionally, dispersal via flight is especially important for species living in fragmented landscapes. Even though,
