Network-scale disruption of RNA-protein interactions by a bioaccumulating small-molecule drug

This study shows that the antidepressant duloxetine disrupts RNA-protein interactions in both human and bacterial cells, revealing a new mechanism of drug action.

Impact of low-calorie sweeteners on gut bacteria is modulated by common xenobiotics

This study investigates interactions between low-calorie sweeteners and xenobiotics on gut bacteria, finding synergistic effects that alter bacterial growth and host cell responses.

Extensive PFAS accumulation by human gut bacteria

This study shows human gut bacteria can accumulate PFAS, with some species like Bacteroides uniformis accumulating them to high concentrations, and identifies mechanisms involving transmembrane transport and efflux pumps.
