Abstract:
Effects of vanadium pentoxide (V2O5) treatment on reproductive function and testicular DNA in male mice were investigated. These functions were evaluated with fertility rate, implants, resorptions, sperm counts, motility, and morphology. The DNA damage in individual testis cells was analyzed by single-cell gel electrophoresis technique (COMET assay). V2O5 treatment resulted in a decrease in fertility rate, implantations, live fetuses, and fetal weight, and an increase in the number of resorptions/dam. Sperm count, motility, and morphology were impaired with the advancement of treatment. Vanadium treatment induced DNA damage depending on the dose in the testis cells that was expressed and detected as DNA migration in the COMET assay. The distribution of DNA migration among cells, a function of dose, revealed that the majority of cells of treated animals expressed more DNA damage than cells from control animals. It is concluded that vanadium pentoxide was a reprotoxic and genotoxic agent in mice.
Insights
Vanadium pentoxide (V2O5) harms male mouse reproduction and DNA. This study found V2O5 decreased fertility, sperm quality, and increased DNA damage, indicating it is both reprotoxic and genotoxic.
Area of Science:
- Toxicology
- Reproductive Biology
- Genetics
Background:
- Vanadium compounds are industrial chemicals with potential health risks.
- Understanding the reproductive and genotoxic effects of vanadium pentoxide (V2O5) is crucial for occupational safety and environmental health.
Purpose of the Study:
- To investigate the impact of V2O5 exposure on male mouse reproductive parameters.
- To assess V2O5-induced DNA damage in testicular cells.
Main Methods:
- Male mice were treated with V2O5.
- Reproductive functions evaluated included fertility rate, implantations, resorptions, sperm count, motility, and morphology.
- DNA damage in testis cells was analyzed using the single-cell gel electrophoresis (COMET assay).
Main Results:
- V2O5 treatment led to reduced fertility, fewer implantations, lower live fetal weight, and increased resorptions.
- Sperm count, motility, and morphology were negatively affected by V2O5 exposure.
- The COMET assay revealed dose-dependent DNA damage in testicular cells of V2O5-treated mice.
Conclusions:
- Vanadium pentoxide (V2O5) acts as a reprotoxic agent, impairing male reproductive function in mice.
- V2O5 is also genotoxic, causing significant DNA damage in mouse testis cells.
- These findings highlight the risks associated with V2O5 exposure.
