The paper models the σE biochemical network to show how transcriptional and post-translational regulation interact to control σE activity under stress, revealing context-dependent feedback mechanisms.

This paper shows that Spo0A~P pulsing frequency controls biofilm matrix deactivation in B. subtilis, independent of growth rate effects on gene dosage and protein dilution.

The paper shows that different particulate matter mixtures cause distinct molecular and morphological changes in lung epithelial cells, with heavy metals causing more severe effects.

This study engineers S. boulardii to control gene expression and gut residence time via diet-responsive systems, enabling precise therapeutic delivery in the mouse gut.

The paper introduces a method to evolve complex bacterial phenotypes using inducible directed evolution, achieving faster growth on tagatose after two rounds of evolution.
