Idiopathic pulmonary fibrosis (IPF) is a debilitating lung disease characterized
by excessive collagen production and fibrogenesis. Apoptosis in lung epithelial
cells is critical in IPF pathogenesis, as heightened loss of these cells promotes
fibroblast activation and remodeling. Changes in glutathione redox status have
been reported in IPF patients. S-glutathionylation, the conjugation of
glutathione to reactive cysteines, is catalyzed in part by
glutathione-S-transferase ? (GSTP). To date, no published information exists
linking GSTP and IPF to our knowledge. We hypothesized that GSTP mediates lung
fibrogenesis in part through FAS S-glutathionylation, a critical event in
epithelial cell apoptosis. Our results demonstrate that GSTP immunoreactivity is
increased in the lungs of IPF patients, notably within type II epithelial cells.
The FAS-GSTP interaction was also increased in IPF lungs. Bleomycin- and
AdTGF?-induced increases in collagen content, ?-SMA, FAS S-glutathionylation, and
total protein S-glutathionylation were strongly attenuated in Gstp(-/-) mice.
Oropharyngeal administration of the GSTP inhibitor, TLK117, at a time when
fibrosis was already apparent, attenuated bleomycin- and AdTGF?-induced
remodeling, ?-SMA, caspase activation, FAS S-glutathionylation, and total protein
S-glutathionylation. GSTP is an important driver of protein S-glutathionylation
and lung fibrosis, and GSTP inhibition via the airways may be a novel therapeutic
strategy for the treatment of IPF.
