Diffusion of transcription factors can drastically enhance the noise in gene expression [PDF]

, 2006
We study by simulation the effect of the diffusive motion of repressor molecules on the noise in mRNA and protein levels in the case of a repressed gene.

TCPs, WUSs, and WINDs: Families of transcription factors that regulate shoot meristem formation, stem cell maintenance, and somatic cell differentiation

Frontiers in Plant Science, 2014
In contrast to somatic mammalian cells, which cannot alter their fate, plant cells can dedifferentiate to form totipotent callus cells and regenerate a whole plant, following treatment with specific phytohormones.

Role of the Two-Component System CiaRH in the Regulation of Efflux Pump SatAB and Its Correlation with Fluoroquinolone Susceptibility

Microbiology Spectrum, 2022
Streptococcus suis is an important pathogen in both pigs and humans. Although the diseases associated with S. suis can typically be treated with antibiotics, such use has resulted in a sustained increase in drug resistance. Bacteria can sense and respond

Crystallization and preliminary crystallographic analysis of dUTPase from the helper phage Φ11 of Staphylococcus aureus [PDF]

, 2011
Staphylococcus aureus superantigen-carrying pathogenicity islands (SaPIs) have a determinant role in spreading virulence genes among bacterial populations that constitute a major health hazard.

NagRBt Is a Pleiotropic and Dual Transcriptional Regulator in Bacillus thuringiensis

Frontiers in Microbiology, 2018
NagR, belonging to the GntR/HutC family, is a negative regulator that directly represses the nagP and nagAB genes, which are involved in GlcNAc transport and utilization in Bacillus subtilis.

The Enterococcus faecalis FabT Transcription Factor Regulates Fatty Acid Biosynthesis in Response to Exogeneous Fatty Acids

Frontiers in Microbiology, 2022
The phospholipid acyl chains of Enterococcus faecalis can be derived either by de novo synthesis or by incorporation of exogenous fatty acids through the fatty acid kinase complex (Fak)-phosphate acyltransferase (PlsX) pathway.

Optimizing periodicity and polymodality in noise-induced genetic oscillators [PDF]

, 2011
Many cellular functions are based on the rhythmic organization of biological processes into self-repeating cascades of events. Some of these periodic processes, such as the cell cycles of several species, exhibit conspicuous irregularities in the form of

Investigation of the potential regulator proteins associated with the expression of major surface protein and dentilisin in Treponema denticola

Journal of Oral Microbiology, 2020
Objective Treponema denticola is involved in ‘chronic’ periodontitis pathogenesis. The mechanism underlying the regulation of the expression of its virulence factors, such as major surface protein (Msp) and prolyl-phenylalanine specific protease ...

RETRACTED: LacI-Family Transcriptional Regulator DagR Acts as a Repressor of the Agarolytic Pathway Genes in Streptomyces coelicolor A3(2)

Frontiers in Microbiology, 2021
Actinobacteria utilize various polysaccharides in the soil as carbon source by degrading them via extracellular hydrolytic enzymes. Agarose, a marine algal polysaccharide composed of D-galactose and 3,6-anhydro-L-galactose (AHG), is one of the carbon ...
