Genome Wide Mapping of Peptidases in Rhodnius prolixus: Identification of Protease Gene Duplications, Horizontally Transferred Proteases and Analysis of Peptidase A1 Structures, with Considerations on Their Role in the Evolution of Hematophagy in Triatominae

Frontiers in Physiology, 2017
Triatominae is a subfamily of the order Hemiptera whose species are able to feed in the vertebrate blood (i.e., hematophagy). This feeding behavior presents a great physiological challenge to insects, especially in Hemipteran species with a digestion ...

Unveiling a Novel Mechanism of Enhanced Secretion, Cargo Loading, and Accelerated Dynamics of Bacterial Extracellular Vesicles Following Antibiotic Exposure

Journal of Extracellular Vesicles, Volume 14, Issue 7, July 2025.
ABSTRACT Antibiotic exposure substantially alters the production mechanisms of bacterial extracellular vesicles (BEVs), which serve as carriers for intercellular exchange of DNA, proteins, and nutrients, yet the underlying mechanisms remain elusive.

Functional profiles of coronal and dentin caries in children

Journal of Oral Microbiology, 2018
Background: Dental caries results from a dysbiosis of tooth-associated biofilms and frequently extends through enamel into dentin which has a different structure and composition.

The pea branching RMS2 gene encodes the PsAFB4/5 auxin receptor and is involved in an auxin-strigolactone regulation loop [PDF]

, 2017
Strigolactones (SLs) are well known for their role in repressing shoot branching. In pea, increased transcript levels of SL biosynthesis genes are observed in stems of highly branched SL deficient (ramosus1 (rms1) and rms5) and SL response (rms3 and rms4)

Elucidating the Mechanism of Temporal Adaptation to Hydrogen Peroxide‐Induced Oxidative Stress in Corynebacterium glutamicum

Microbial Biotechnology, Volume 18, Issue 6, June 2025.
In this study, RNA‐seq was employed to investigate the temporal transcriptional response of C. glutamicum ATCC 13032 to external H2O2 at 720 mM (2.45% w/w). The results reveal significant changes in gene expression across multiple pathways, including peroxide scavenging, central metabolism, sulphur and iron metabolism, amino acid biosynthesis, and DNA ...

MCRS2 represses the transactivation activities of Nrf1

BMC Cell Biology, 2009
Background Nrf1 [p45 nuclear factor-erythroid 2 (p45 NF-E2)-related factor 1], a member of the CNC-bZIP (CNC basic region leucine zipper) family, is known to be a transcriptional activator by dimerization with distinct partners, such as Maf, FosB, c-Jun,

Characterisation of the effects of salicylidene acylhydrazide compounds on type three secretion in Escherichia coli O157:H7 [PDF]

, 2009
Recent work has highlighted a number of compounds that target bacterial virulence by affecting gene regulation. In this work, we show that small-molecule inhibitors affect the expression of the type III secretion system (T3SS) of <i>Escherichia ...

Harnessing promoter elements to enhance gene editing in plants: perspectives and advances

Plant Biotechnology Journal, Volume 23, Issue 5, Page 1375-1395, May 2025.
Summary Genome‐edited plants, endowed with climate‐smart traits, have been promoted as tools for strengthening resilience against climate change. Successful plant gene editing (GE) requires precise regulation of the GE machinery, a process controlled by the promoters, which drives its transcription through interactions with transcription factors (TFs ...

Engineering archaeal membrane‐spanning lipid GDGT biosynthesis in bacteria: Implications for early life membrane transformations

mLife, Volume 4, Issue 2, Page 193-204, April 2025.
Abstract Eukaryotes are hypothesized to be archaeal–bacterial chimeras. Given the different chemical structures of membrane phospholipids in archaea and bacteria, transformations of membranes during eukaryogenesis that led to the bacterial‐type membranes of eukaryotic cells remain a major conundrum.
