Gastric microbiota‐specific signatures in adults with obesity and Helicobacter pylori‐negative gastritis

open access: yesEuropean Journal of Clinical Investigation, EarlyView.
Abstract Background The role of the gastric microbiome in the pathophysiology of gastritis beyond Helicobacter pylori (HP) infection is poorly understood and has remained unexplored in patients with obesity. The aim of this study was to analyse gastric mucosa‐associated microbiota in patients with obesity and nonatrophic chronic gastritis in the ...

d‐amino acids: new functional insights

open access: yesThe FEBS Journal, EarlyView.
This review explores recent advances in understanding d‐amino acids (d‐AAs) and their pivotal roles across organisms, from plants to humans. d‐AAs have been implicated in key physiological processes, including cancer, inflammation, immune regulation, kidney disease, diabetes, and nervous system function.

Tracing the evolutionary pathway: on the origin of mitochondria and eukaryogenesis

open access: yesThe FEBS Journal, EarlyView.
This study examines the stepwise transition from archaeal–bacterial associations to the emergence of eukaryotic cells. Metabolic cooperation and endosymbiosis fostered ecological and genetic integration, with extensive gene transfer reshaping host biology.

The toxic effects of meta‐tyrosine are related to its misincorporation into the proteome and to altered metabolism in cyanobacteria

open access: yesThe FEBS Journal, EarlyView.
This study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...

Emerging roles for integrated stress response signaling in homeostasis

open access: yesThe FEBS Journal, EarlyView.
Integrated stress response (ISR), an evolutionarily conserved eukaryotic stress‐adaptive program in eukaryotes, has also been implicated in homeostatic functions. This review covers a broad body of literature and presents several homeostatic functions of ISR in the absence of stress: (a) developmental processes (morphogenesis, differentiation, aging), (
