This study enhances the knowledge on the molecular pathogenesis of idiopathic pulmonary fibrosis (IPF). To date, there is no information available on the role of peroxisomes in lung fibrosis. In our study we demonstrate that peroxisomal biogenesis and metabolism is compromised in tissue samples as well as in fibroblasts of IPF patients and in bleomycin-induced fibrosis mouse model. Moreover, RNAi-mediated knockdown of peroxisomal biogenesis leads to a profibrotic response in control and IPF fibroblasts suggesting that the reduction of peroxisomal function in IPF would contribute to the profibrotic phenotype of this devastating disease. Our work opens a new field of research in the area of lung fibrosis and might lead to novel treatment strategies against IPF by modulating the peroxisomal compartment.
