HIP/PAP protects against bleomycin-induced lung injury and inflammation and subsequent fibrosis in mice.

ABSTRACT: Hepatocarcinoma-intestine-pancreas/pancreatitis-associated protein (HIP/PAP), a C-type lectin, exerts anti-oxidative, anti-inflammatory, bactericidal, anti-apoptotic, and mitogenic functions in several cell types and tissues. In this study, we explored the role of HIP/PAP in pulmonary fibrosis (PF). Expression of HIP/PAP and its murine counterpart, Reg3B, was markedly increased in fibrotic human and mouse lung tissues. Adenovirus-mediated HIP/PAP expression markedly alleviated bleomycin (BLM)-induced lung injury, inflammation, and fibrosis in mice. Adenovirus-mediated HIP/PAP expression alleviated oxidative injury and lessened the decrease in pulmonary superoxide dismutase (SOD) activity in BLM-treated mice, increased pulmonary SOD expression in normal mice, and HIP/PAP upregulated SOD exp
