Evolutionary interplay between viruses and R‐loops
FEBS Letters, Volume 599, Issue 21, Page 3012-3028, November 2025.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Exploring Bacterial Interactions Under the Stress Gradient Hypothesis in Response to Selenium Stress
Environmental Microbiology Reports, Volume 17, Issue 5, October 2025.Under the model of the stress gradient hypothesis, as selenium (Se) stress increases, bacterial interactions shift from net competitive (low stress) to net facilitative/helpful interactions (high stress). This allows Se susceptible species to benefit from detoxification mechanisms provided by Se detoxifying bacteria which remove toxins from the ...

A force-activated trip switch triggers rapid dissociation of a colicin from its immunity protein.
PLoS Biology, 2013 Colicins are protein antibiotics synthesised by Escherichia coli strains to target and kill related bacteria. To prevent host suicide, colicins are inactivated by binding to immunity proteins.

Identification and Evaluation of the Urinary Microbiota Associated With Bladder Cancer
Cancer Innovation, Volume 4, Issue 4, August 2025.Urinary microbiota in Chinese bladder cancer patients reveals distinct profiles between non‐muscle‐invasive and muscle‐invasive diseases, with potential biomarkers like Peptoniphilus spp. in high‐risk MIBC, suggesting a role in cancer progression. Dysbiosis may serve as a stratification marker for bladder cancer risk. ABSTRACT Background Bladder cancer

Antibiotics, 2016 Colicins are bacterial toxins produced by some Escherichia coli strains. They exhibit either enzymatic or pore-forming activity towards a very limited number of bacterial species, due to the high specificity of their reception and translocation systems ...

Synthetic Biology‐Based Engineering Living Therapeutics for Antimicrobial Application
Exploration, Volume 5, Issue 4, August 2025.This perspective highlights synthetic biology‐driven antibacterial strategies, focusing on three innovative approaches: engineered bacteriophages for precision bacterial targeting, reprogrammed microbes that detect quorum‐sensing signals or metabolites to release antimicrobials, and engineering mammalian cells that recognize pathogen‐associated ...

Colicin crystal structures: pathways and mechanisms for colicin insertion into membranes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 2002 The X-ray structures of the channel-forming colicins Ia and N, and endoribonucleolytic colicin E3, as well as of the channel domains of colicins A and E1, and spectroscopic and calorimetric data for intact colicin E1, are discussed in the context of the mechanisms and pathways by which colicins are imported into cells. The extensive helical coiled-coil

Food Science &Nutrition, Volume 13, Issue 8, August 2025.Targeting the potential sources and risk factors for antibiotic resistance transmittance and development of antibiotic resistant‐free probiotics. ABSTRACT Antibiotic resistance (AR) in lactic acid bacteria (LAB) has become an emerging concern in the probiotic and food industries. LAB, a key component of the human microbiota and widely used in probiotic
