Özet

Approximately 20 million new cancer cases have occurred worldwide, and dose limitation occurs because of the liver and kidney toxicity of chemotherapeutic agents. Inflammation/apoptosis/ROS pathways appear to be activated in the liver and kidney toxicity of chemotherapeutic agents. This study was conducted to investigate the potential effects of silymarin (SLY) use against docetaxel (DTX)-induced liver and kidney damage in rats. For this purpose, 30 mg/kg DTX was administered intraperitoneally to Sprague Dawley rats on the first day of the study, followed by SLY (25 or 50 mg/kg/day) orally for 7 days. Then, various analyses were performed on liver and kidney tissues using biochemical, molecular and histological methods. The data obtained showed that DTX administration suppressed antioxidant markers and increased lipid peroxidation in liver and kidney tissues. It was also determined that DTX administration triggered markers of endoplasmic reticulum stress, inflammation, apoptosis and autophagy. On the other hand, SLY treatment increased enzymatic and non-enzymatic antioxidant levels and decreased malondialdehyde levels. Additionally, SLY alleviated DTX-induced endoplasmic reticulum stress, inflammation, apoptosis and autophagy in liver and kidney tissues. Immunohistochemical analyses showed that DTX increased the density of 8-OHdG positive cells in liver and kidney tissues, while oxidative DNA damage decreased after SLY administration. ALT, AST, ALP, Urea and Creatinine levels increased in the DTX group and decreased in the SLY treatment groups. In conclusion, DTX administration caused toxicity in liver and kidney tissues and damaged tissue integrity, while SLY treatment alleviated DTX-induced toxicity.
