Abstract

Context: Cordycepin (COR), from L., (Cordycipitaceae), is a valuable agent with immense health benefits.

Objective: The protective effects of COR in ageing-associated oxidative and apoptosis events and hydrogen peroxide (HO)-exposed spermatogenesis gene alterations in TM3 Leydig cells was investigated.

Materials And Methods: Male Sprague-Dawley rats were divided into young control (YC), aged control (AC) and COR treated (COR-20) aged groups. COR-20 group received daily doses of COR (20 mg/kg) for 6 months. Cell viability and hormone levels were analysed by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] and enzyme immunoassay kits with COR treated at 1, 5, and 10 μg/mL. Oxidative enzymes, spermatogenic, and apoptotic expression in testis tissues were evaluated by Western blotting and real-time RT-PCR.

Results: COR treatment (1, 5, and 10 μg/mL) significantly ( 0.05 ∼ 0.001) inhibited the HO-induced decrease in the percentage of viable cells (from 63.27% to 71.25%, 85.67% and 93.97%, respectively), and reduced the malondialdehyde (MDA) content (from 4.28 to 3.98, 3.14 and 1.78 nM MDA/mg protein, respectively). Further, the decreased antioxidant enzymes (glutathione--transferase mu5, glutathione peroxidase 4 and peroxiredoxin 3), spermatogenesis-related factors (nectin-2 and inhibin-α) and testosterone levels in HO-exposed TM3 cells were significantly ( 0.05 ∼ 0.001) ameliorated by COR. In aged rats, COR (20 mg/kg) restored the altered enzymatic and non-enzymatic antioxidative status and attenuated the apoptotic p53 and Bax/Bcl-2 expression significantly ( 0.05).

Conclusion: COR might be developed as a potential agent against ageing-associated and oxidative stress-induced male infertility.
