Figure 2From: Nitric oxide induces MUC5AC mucin in respiratory epithelial cells through PKC and ERK dependent pathwaysNOR-1 increased the transcriptional activity of MUC5AC promoter. A549 cells were transfected with MUC5AC promoter. The transfected cells were treated with vehicle or different concentrations of NOR-1 for 1 hr and then harvested for measurement of luciferase activities. ** significantly different, p < 0.01, from MUC5AC promoter-alone transfection group.Back to article page
