Uteroglobin (UG) is an anti-inflammatory protein secreted by the airway epithelia of all mammals. UG-knockout (UG-KO) mice sporadically develop focal pulmonary fibrosis (PIT), a group of complex interstitial disorders of the lung that has high mortality and morbidity; however, the molecular mechanism(s) remains unclear. We report here that UG-KO mice are extraordinarily sensitive to bleomycin, an anti-cancer agent known to induce PIT and readily develop PIT when treated with an extremely low dose of bleomycin that has virtually no effect on the wild type littermates. We further demonstrate that UG prevents PF suppressing bleomycin-induced production of proinflammatory T-helper 2 cytokines and TGF-beta, which are also pro-fibrotic. Our results define a critical role of UG in preventing the development of PIT and provide the proof of principle that recombinant UG may have therapeutic potential.
