Abstract

Despite the fact that the use of antibiotics is increasing worldwide, it is clear that antibiotics can lead to oxidative stress. This is the first study to make a comparison of the impact of frequently prescribed antibiotics, including amoxicillin, gentamicin, and cefazolin sodium, on the gene, protein, and activity of glutathione reductase (GR), which is one of the primary antioxidant enzymes, in mouse liver and kidney tissues. First, the GR enzyme was purified by the 2 ',5 '-ADP Sepharose 4B affinity chromatography with a specific activity of 84.615 EU/mg protein and 9.63 EU/mg protein from the mouse liver and kidney, respectively. The in vitro inhibitory effects of the antibiotics in question was determined. While cefazolin sodium did not exhibit any inhibitory effect, gentamicin and amoxicillin inhibited GR activity in both tissues. Furthermore, the in vivo effects of these drugs were investigated, and amoxicillin and cefazolin sodium-inhibited GR activity in both liver and kidney tissues, while gentamicin did not have any effect on the kidney. Besides, while gentamicin downregulated and cefazolin sodium upregulated Gr gene expression, amoxicillin did not alter it. Protein expression was only affected by the administration of cefazolin sodium in the kidney. This study is important as it demonstrates that while amoxicillin and gentamicin showed parallel effects on the GR activity in liver and kidney tissues both in vitro and in vivo, cefazolin sodium had a very strong effect on hepatic and renal GR in vivo. Furthermore, the antibiotics used in this study induced oxidative stress in both tissues.
