ABSTRACT
This study aimed to investigate the protective effects of glucose selenol on cadmium (Cd)-induced testicular toxicity. Twenty-four male Sprague-Dawley (SD) rats were randomly divided into four groups. Cd was administered orally at a dose of 40â¯mg/L or in combination with orally administered glucose selenol at doses of 0.15â¯mg/L and 0.4â¯mg/L for 30 days. The results showed that sperm quality decreased and testicular tissue was damaged in the Cd group; Glucose selenol significantly attenuated the negative effects by improving sperm quality and reducing testicular damage. Transcriptome sequencing analysis showed that Cd stress affected spermatogenesis, sperm motility, oxidative stress, blood-testis barrier and protein metabolism. Four clusters were obtained using the R Mfuzz package, which clustered highly expressed genes under different administrations, and 36 items were enriched. Notably, protein phosphorylation was enriched in the Cd group and is considered to play a key role in the response to Cd stress. We identified fifty-six target selenium (Se) and Cd co-conversion differentially expressed genes (DEGs), including three genes relating to spermatogenesis (Dnah8, Spata31d1b, Spata31d1c). In addition, the obtained DEGs were used to construct a protein-protein interaction network, co-processed with Se and Cd, and 5 modules were constructed. Overall, the analyses of rat testicular physiology and gene expression levels offer new insights into the reproductive toxicity of Cd in rats, and provide potential application prospects for glucose selenol in alleviating the impact of Cd-induced testicular damage.
