Abstract:
The indiscriminate use of anabolic androgenic steroids (AAS) has motivated researchers to investigate the mutagenic action of these substances. The present study, using the mouse bone marrow micronucleus test, evaluates the genotoxic potential of testosterone cypionate (deposteron). Male Swiss mice received intramuscular injections of deposteron at three doses. The animals were sacrificed 24, 48, or 72h after treatment and bone marrow was removed immediately, followed by scoring to count the micronuclei in 2000 polychromatic erythrocytes (PCE). Two hundred erythrocytes/animal were analyzed to determine the PCE-NCE (normochromatic erythrocyte) relationship and to determine the cytotoxic effects. The animals treated with deposteron at the highest dose presented greater numbers of micronuclei. The highest dose caused a decrease in the PCE/NCE relationship, indicating a cytotoxic effect. We conclude that deposteron is genotoxic and cytotoxic in mice.
Insights
Testosterone cypionate (deposteron) demonstrates genotoxic and cytotoxic effects in mice. This study found increased micronuclei and decreased erythrocyte production following deposteron administration, highlighting potential risks associated with its use.
Area of Science:
- Toxicology
- Genetics
- Pharmacology
Background:
- Anabolic androgenic steroids (AAS) are frequently misused, prompting research into their mutagenic potential.
- Understanding the genotoxic effects of specific AAS is crucial for public health and safety.
Purpose of the Study:
- To evaluate the genotoxic and cytotoxic potential of testosterone cypionate (deposteron) using an in vivo mouse model.
- To assess the dose-dependent effects of deposteron on bone marrow cells.
Main Methods:
- The mouse bone marrow micronucleus test was employed to assess genotoxicity.
- Male Swiss mice were administered intramuscular injections of deposteron at varying doses.
- Micronuclei counts in polychromatic erythrocytes (PCE) and the PCE/NCE ratio were analyzed at 24, 48, and 72 hours post-treatment.
Main Results:
- A significant increase in micronuclei formation was observed in animals treated with the highest dose of deposteron.
- The highest dose of deposteron induced a decrease in the PCE/NCE ratio, indicating cytotoxic effects on bone marrow.
- Dose-dependent genotoxic and cytotoxic effects were evident.
Conclusions:
- Testosterone cypionate (deposteron) exhibits genotoxic activity in mice.
- Deposteron also demonstrates cytotoxic effects, impacting bone marrow cell proliferation.
- The findings suggest that deposteron poses risks associated with its indiscriminate use.
