Abstract

Tibial Dyschondroplasia (TD), a metabolic disease of fast growing poultry birds that effects the growth of bone and cartilage, is characterized by anorexia, mental depression and lameness. Wnt/β-catenin pathway can mediate the occurrence of TD, and previous study showed the therapeutic effect of TanshinoneⅡA to TD Broilers. However there is no report about the effect of TanshinoneⅡA treating TD broiler chicken through wnt/β-catenin pathway. The objective of this study was to explore the potential mechanism of how Tanshinone II A treats TD. Hematoxylin and eosin staining was used to study histologic pathology of growth plates. Key gene expressions were tested by western blot and reverse transcription quantitative real-time PCR. Results compared with control groups, showed the TD broilers' growth plate performed significantly better by treating with TanshinoneⅡA. After chickens treated by TanshinoneⅡA, the gene and protein expression of WNT5α and BMP-2 were increased (P < 0.05), but the β-catenin were decreased (P < 0.05), which are all key genes expressed in wnt/β-catenin pathway. Therefore, TanshinoneⅡA can potentially treat TD by affecting the expression of genes in wnt/β-catenin pathway and it has availability to use as treatment for TD broilers.
