Quinolone tolerance in Escherichia coli due to defects in the adenosine ribonucleotides de novo biosynthesis pathway

open access: yesmLife, Volume 5, Issue 2, Page 217-228, April 2026.
Abstract Central carbon metabolism is thought to link reactive oxygen species (ROS) with antibiotic‐mediated bacterial death. During enrichment screening of Escherichia coli with the first‐generation quinolone oxolinic acid, unstable antibiotic‐tolerant mutants containing deficiencies in purB were obtained.

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 781-805, February 2026.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

The Role of APOBEC3B in Cancer: Mechanisms, Clinical Challenges, and Therapeutic Opportunities

open access: yesHuman Mutation, Volume 2026, Issue 1, 2026.
Apolipoprotein B mRNA editing enzyme catalytic polypeptide‐like 3B (APOBEC3B, A3B) is a key cytidine deaminase that induces genomic instability and clonal evolution in diverse malignancies. Although A3B plays a key role in the onset and advancement of various cancers, a comprehensive model bridging its multifaceted mechanisms and clinical translation ...
