[Renal and hepatic toxicity studies in mice treated with sodium saccharin: breaks in single-stranded DNA]
Abstract:
The renal and hepatic effects of in vivo treatment with saccharin have been determined as increased DNA elutability on filter. A direct dose-damage relationship was not observed in the kidney and in the liver DNA of treated mice. Doses of 50, 100 and 200 mg/Kg seem to induce in almost all the experiments the same level of single-stranded breaks. The DNA elutability is increased in the range 130-210 % if compared with controls.
Insights
Saccharin treatment in mice increased DNA strand breaks in the kidney and liver. No direct dose-damage relationship was observed, with similar effects across tested doses.
Area of Science:
- Toxicology
- Molecular Biology
- Genetics
Context:
- Investigating the in vivo effects of artificial sweeteners.
- Assessing potential genotoxicity of saccharin.
- Evaluating DNA damage in mammalian organs.
Purpose:
- To determine the renal and hepatic effects of saccharin exposure.
- To investigate the relationship between saccharin dose and DNA damage.
- To quantify DNA strand breaks induced by saccharin.
Summary:
- In vivo treatment with saccharin led to increased DNA elutability in mouse kidney and liver.
- A direct dose-response relationship for DNA damage was not observed.
- Similar levels of single-stranded DNA breaks were induced across saccharin doses (50, 100, 200 mg/Kg).
- DNA elutability increased by 130-210% compared to control groups.
Impact:
- Highlights potential genotoxic effects of saccharin.
- Informs risk assessment for artificial sweetener consumption.
- Suggests further research into mechanisms of saccharin-induced DNA damage.
