Figure 4From: Induction and regulation of matrix metalloproteinase-12in human airway smooth muscle cellsWestern blot analysis of MMP-12 protein expression in ASMC and the effect of IL-1β. Cells were incubated in 6-well plates in the absence or presence of 10 ng/ml IL-1β for 24–72 hours. MMP-12 protein expression was analysed by Western blot (A) and shown as a ratio of GAPDH obtained by densitometric analysis (B). Results are mean ± SEM from three ASMC donors.Back to article page
