HNE-Induced MUC5AC Protein Expression: Time Course and Inhibitor Effects #3836334 (License: Personal Use)

Panel A illustrates a dose- and time-dependent increase in MUC5AC protein levels following HNE exposure, with statistically significant elevation observed at 5, 10, and 30 minutes. Panel B compares the effect of HNE alone versus co-treatment with inhibitors ICI (likely an inhibitor of a signaling pathway such as NF-κB or EGFR) and SLPI (secretory leukocyte protease inhibitor), revealing strong suppression of MUC5AC induction by both agents. Error bars represent standard deviation, and asterisks denote p < 0.05 vs. control.

This figure is commonly used in respiratory or mucosal immunology research papers to demonstrate oxidative stress-induced mucin overproduction and potential therapeutic interventions; users seeking mechanistic insights into asthma, COPD, or chronic bronchitis pathogenesis would find it relevant.
