Currently, there is no effective treatment for PF or idiopathic pulmonary fibrosis (IPF). The aim of this study was to investigate the effects of Sodium Houttuyfonate (SH) on bleomycin (BLM) induced PF mice model. Our results indicated that SH could attenuate BLM induced lung injury by reducing the inflammation, fibrogenesis and lung\/body weight ratio. The proposed mechanisms for the protective effects of SH include: 1) improvement of pulmonary function in BLM mice, for instance, it can elevate the vital capacity (VC), increase the forced expiratory flow at 50% of forced vital capacity (FEF50) and improve other pulmonary function indices; 2) inhibition of collagen formation in BLM mice; 3) attenuation of the elevation of inflammatory cytokines, such as interleukin-1\u03b2 (IL-1\u03b2), IL-6, and tumor necrosis factor-\u03b1 (TNF-\u03b1), which are triggered by BLM administration; 4) reduction of the mRNA level and protein production of transforming growth factor-\u03b21 (TGF-\u03b21) in BLM mice. Furthermore, it was found that the protective effects of SH against BLM induced PF in mice was comparable to that of prednisone acetate (PA) tablets, a widely used drug for immunological diseases. Although <jats:italic>Houttuynia Cordata<\/jats:italic> Thunb has been widely used in China for lung infection and inflammation, the mechanism has not yet been fully elucidated. Our study provides the evidence that SH is an effective compound against pulmonary injury, irritation and fibrogenesis.<\/jats:p>","DOI":"10.3389\/fphar.2021.596492","type":"journal-article","created":{"date-parts":[[2021,2,25]],"date-time":"2021-02-25T09:14:39Z","timestamp":1614244479000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":36,"title":["Sodium Houttuyfonate Inhibits Bleomycin Induced Pulmonary Fibrosis in Mice"],"prefix":"10.3389","volume":"12","author":[{"given":"Yun-hui","family":"Shen","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ming-han","family":"Cheng","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin-yu","family":"Liu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"De-wei","family":"Zhu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2021,2,25]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"1646","DOI":"10.1126\/science.1071809","article-title":"Signal transduction by the TGF-beta superfamily","volume":"296","author":"Attisano","year":"2002","journal-title":"Science"},{"key":"B2","doi-asserted-by":"publisher","first-page":"274","DOI":"10.1016\/j.phrs.2008.02.001","article-title":"TGF-beta1 targets the GSK-3beta\/beta-catenin pathway via ERK activation in the transition of human lung fibroblasts into myofibroblasts","volume":"57","author":"Caraci","year":"2008","journal-title":"Pharmacol.
