Pretreatment of airway epithelial cells with Calpain inhibitors attenuates mucin secretion. Relative levels of mucin secretion in NHBE cells after treatment with 250nM PMA with or without pre-treatment with Calpain inhibitors: 20μM Z-LLY-CHO (CHO) or 20μM Z-LLY-FMK (FMK) for 15 min. Secretion was measured 3 min after PMA addition. († p<0.01, †† p<0.001 relative to PMA-stimulated, all values expressed as mean ± SEM, n=4).
