Abstract

Chronic cigarette smoke (CS) exposure induces prostate deficits. We previously found that swertiamarin had prostatic protective potential. This study was to investigate the possible protective effect of swertiamarin against CS-induced prostate dysfunction on human prostate epithelial cells, stromal cells and rats. Rat prostate collagen deposition and fibrosis were assessed by sirius red staining and measuring hydroxyproline content, as well as by qPCR and western blot analysis for fibrotic extracellular matrix components. Prostatic levels of oxidative stress and inflammatory-related factors were also analyzed. In order to explore its underling mechanisms, the activities of Hedgehog signaling pathway and epithelial-mesenchymal transition of human prostate cells and rat prostate tissue were estimated. It was found that swertiamarin ameliorated CS-induced prostatic collagen deposition, relieved oxidative stress and local inflammation, inhibited the activation of Hedgehog signaling pathway and attenuated epithelial-mesenchymal transition. It indicated that swertiamarin could ameliorate CS-induced prostatic fibrosis by inhibiting epithelial-mesenchymal transition and Hedgehog pathway.
