Effects of MMP-12 on IL-13–induced TGF-β1 bioactivity and tissue fibrosis. (a) Transgene– and transgene+ CC10-rtTA-IL-13 mice were placed on dox water for 4 weeks. BAL fluids were then obtained and the levels of bioactive (striped bars) and total (black bars) TGF-β1 were assessed using mink lung epithelial cells as described in Methods. *P < 0.05. (b) BAL fluids were obtained from 3-month-old CC10-IL-13 transgene– and transgene+ mice, and the levels of bioactive and total TGF-β1 were assessed using mink lung epithelial cells as described in Methods. (c) Trichrome stains are used to evaluate the subepithelial fibrosis in lungs from 3-month-old CC10-IL-13 transgene– and transgene+ mice with wild-type and null MMP-12 loci.
