Ginsenoside Rg1 regulates thiram-induced chondrocytes' apoptosis and angiogenesis in broiler chickens.

Abstract

Tibial dyschondroplasia (TD) is a developmental cartilaginous disease due to thiram toxicity. The abnormity of chondrocytes and insufficient angiogenesis within the growth plate are the major factors leading to the occurrence of TD in most cases. In the current study, we evaluated the beneficial effects of ginsenoside (Rg1) against thiram-induced TD for knowing the possible underlying mechanisms in broiler chickens through in vivo and in vitro assessment. Arbor acres broilers (1-day-old, n = 120) were randomly divided for the in vivo evaluation. The control broilers were fed under normal conditions during the whole experiment cycle (18 days). The TD broilers were fed with 50 mg/kg thiram, while the treatment group was given 40 mg/kg of Rg1. According to our findings, thiram caused a decrease in production performance and tibia parameters (p < 0.05), which were significantly reversed by Rg1 administration. In addition, the results from the histological evaluation showed that the proliferative zone had a smaller number of blood vessels, surrounded by inviable chondrocytes, proving apoptosis during the occurrence of TD, while Rg1 treatment significantly increased blood vessels and decreased apoptotic cells. Furthermore, it was found that Rg1 effectively ameliorated the angiogenesis by regulation of HIF-1α/VEGFA/VEGFR2 signaling pathway and the chondrocytes' apoptosis via the mitochondrial pathway. Hence, these findings suggest that Rg1 might be a perfect choice in the prevention and treatment of TD via regulating chondrocytes apoptosis and angiogenesis. Also, it might be a potential therapeutic drug for humans to overcome different bone disorders, involving chondrocytes.
