Figure 1.
PMA exposure increases Calpain activity in airway epithelial cells. Relative levels of Calpain activity in HBE1 cells after stimulation with 250nM PMA are shown. Label on X axis (time) refers to time post PMA addition. Calpain activity is significantly increased within 2 min of exposure to PMA. (* p<0.05 relative to 0 time control, all values expressed as mean ± SEM, n=3).
