Abstract:
To evaluate the impact potential of nandrolone decanoate on DNA damage in multiple organs of Wistar rats by means of single-cell gel (comet) assay and micronucleus test. A total of 15 animals were distributed into three groups of five animals each as follows: control group = animal not exposed to nandrolone decanoate; experimental group = animals exposed to nandrolone decanoate for 24 h at 5 mg/kg subcutaneously; and experimental group = animals exposed to nandrolone decanoate for 24 h at 15 mg/kg subcutaneously. Significant statistical differences (p < 0.05) were noted in peripheral blood, liver, and heart cells exposed to nandrolone decanoate at the two doses evaluated. A clear dose-response relationship was observed between groups. Kidney cells showed genetic damage at only the highest dose (15 mg/kg) used. However, micronucleus data did not show remarkable differences among groups. In conclusion, the present study indicates that nandrolone decanoate induces genetic damage in rat blood, liver, heart, and kidney cells as shown by single-cell gel (comet) assay results.
Insights
Nandrolone decanoate exposure caused DNA damage in Wistar rat blood, liver, and heart cells. Kidney cells showed damage only at higher doses, indicating potential genotoxicity of this anabolic steroid.
Area of Science:
- Toxicology
- Genetics
- Pharmacology
Background:
- Anabolic-androgenic steroids (AAS) like nandrolone decanoate are performance-enhancing drugs.
- Potential adverse effects, including genotoxicity, require thorough investigation.
Purpose of the Study:
- To assess the genotoxic potential of nandrolone decanoate in Wistar rats.
- To evaluate DNA damage in multiple organs using specific assays.
Main Methods:
- Wistar rats were divided into control and two experimental groups receiving nandrolone decanoate (5 mg/kg or 15 mg/kg).
- Single-cell gel (comet) assay and micronucleus test were employed to detect DNA damage.
- Peripheral blood, liver, heart, and kidney cells were analyzed.
Main Results:
- The comet assay revealed significant DNA damage in blood, liver, and heart cells at both tested doses.
- A dose-response relationship was observed for nandrolone decanoate-induced genetic damage.
- Kidney cells exhibited genetic damage solely at the higher dose (15 mg/kg).
- Micronucleus test results did not show significant differences among the groups.
Conclusions:
- Nandrolone decanoate induces significant genetic damage in rat blood, liver, heart, and kidney cells, as evidenced by comet assay results.
- The findings highlight the potential genotoxic risk associated with nandrolone decanoate administration.
