The anti‐spermatogenic activity of nanoliposomes loaded with Heracleum persicum phenolic compounds in Balb/C mice

Abstract

AbstractThere are various types of bioactivities that have been reported for Heracleum persicum species, such as antioxidant, anti‐inflammatory, and cytotoxicity properties. In the current study, the bio‐accessibility of H. persicum bioactive compounds was improved by purifying its phenolic‐enriched fractions (PEF) and encapsulating them into nanoliposomes to analyze its cytotoxic impacts on mice testicular tissue and their fertility status. Nano liposomal H. persicum PEF (NL‐HPEF) was prepared by ultrasound‐based encapsulation of HPEF and L‐agranular lecithin mixture. The size, morphology, and stability of NL‐HPEF were characterized by dynamic light scattering, field emission scanning electron microscopy, and zeta potential analysis. The 18 white male Balb/c mice (20–25 g) at 3 treatment groups were provided to study the NL‐HPPF cytotoxicity by measuring the mice liver enzyme including aspartate aminotransferase (AST), ALP and alanine aminotransferase (ALT), testis lipid peroxidation, and testicular tissue destruction levels. Moreover, the mice's fertility was evaluated by studying the Adam3, Prm1, Spata19, and Tnp2 gene expression in the testicular tissues. The obtained results manifested that the synthesized NL‐HPEF was stable (193.7 nm) and exhibited a notable cytotoxic impact on the mice's liver (ALT and AST enhancement levels) and testicular tissues. Moreover, their increasing treatment doses impaired the male mice's fertility by decreasing the sperm count, viability, and motility. In addition, fertility suppression was verified by decreasing serum testosterone and downregulating the Adam3, Prm1, Spata19, and Tnp2 gene expression in their testicular tissues. The male mice's fertility was significantly (p < 0.05) suppressed by increasing treatment doses of NL‐HPEF. Hence, the NL‐HPEF could be considered a promising alternative to replace the male chemical contraceptives drugs.
