NAC inhibits HA fragment-induced gene expression in airway epithelial cells. ELISA for (A) IP-10 and (B) IL-8 of cultured cell supernatants from NCI H292 cells stimulated HA fragments (250 μg/ml) in the presence of NAC in concentrations as indicated at 37°C for 18 h. These data represent the average of 4 identical, independent experiments.
