Pseudomonas aeruginosa Pyocyanin Increases Airway Mucin Biosynthesis by SIRT1-Mediated FOXA2 Inactivation

The potent redox-cycling Pseudomonas aeruginosa secondary metabolite pyocyanin induces acute and persistent oxidative stress in diseased airways. Pyocyanin promotes goblet cell hyperplasia and metaplasia and exacerbates the mucus burden. Forkhead Box A2 (FOXA2) is a key pioneer f...

Pseudomonas aeruginosa-derived volatile organic compounds modulate AhR signaling to dysregulate airway mucus homeostasis

Pseudomonas aeruginosa frequently infects chronically diseased lungs and exacerbates airway mucus hypersecretion and failure in clearance. P. aeruginosa is metabolically versatile and secretes multiple volatile organic compounds (VOCs), which have been scrutinized as potential bi...
