Abstract_ Background The most common pathologic form of pulmonary fibrosis arises from excessive deposition of extracellular matrix proteins such as collagen. The 47 kDa heat shock protein 47 HSP47 is a collagen-specific molecular chaperone that has been shown to play a major role during the processing and or secretion of procollagen. Objectives To determine whether inhibition of HSP47 could have beneficial effects in mitigating bleomycin-induced pulmonary fibrosis in rats. Methods All experiments were performed with 250-300 g male Wistar rats. Animals were randomly divided into five experimental groups that were administered l saline alone 2 bleomycin alone 3 antisense HSP47 oligonucleotides alone 4 bleomycin antisense HSP47 oligonucleotides and 5 bleomycin sense control .
