Fig. 1From: Ceramide induces MMP-9 expression through JAK2/STAT3 pathway in airway epitheliumBEAS-2B cells were treated with C6-ceramide (10 μM, 5 μM, or 2.5 μM) or 0.1% DMSO (vehicle) for 24 h. The MMP-9 levels were determined by RT-qPCR (a) and ELISA (b). n = 3 per group. *P < 0.05, **P < 0.01 vs controls that were treated with 0.1% DMSOBack to article page
