Abstract
Plasticizers are widely employed in various applications. Therefore, these products may have an impact on the biological systems of humans and other organisms. Thus, seeking a potent and eco-friendly protective agent becomes a great challenge. The current study investigated the underlying molecular mechanism associated with the protective effect of curcumin-loaded nanoliposomes (CUR nanoliposomes) against DBP-induced testicular damage. A total of twenty-four adult male rats were split up into four groups: the control group, the CUR nanoliposomes-treated group (100 mg/kg/day by oral gavage), the DBP-treated group (500 mg/kg/day by oral gavage), and the last group that received both treatments simultaneously for 60 days. The results showed that DBP exposure induced Leydig cell damage and testicular injury, represented by decreased serum sex hormone levels, downregulation of INSL3 gene expression, elevated testicular LDH, and aberrant sperm rate, as well as pathologically abnormal testicular anatomy. These testicular injuries are associated with redox state imbalance (elevated MDA, reduced CAT activity, and downregulation of Nrf2 and SOD gene expression), elevated apoptosis biomarkers (CASP3 and CASP9), and dysregulation of the PI3K/AKT/mTOR pathway. Co-administration of CUR nanoliposomes succeeded in reversing DBP-induced testicular damage. CUR nanoliposome-induced testicular protection could be attributed to the modulation of the PI3K/AKT/mTOR pathway.
期刊介绍:
Drawing from a large number of disciplines, Reproductive Toxicology publishes timely, original research on the influence of chemical and physical agents on reproduction. Written by and for obstetricians, pediatricians, embryologists, teratologists, geneticists, toxicologists, andrologists, and others interested in detecting potential reproductive hazards, the journal is a forum for communication among researchers and practitioners. Articles focus on the application of in vitro, animal and clinical research to the practice of clinical medicine.
All aspects of reproduction are within the scope of Reproductive Toxicology, including the formation and maturation of male and female gametes, sexual function, the events surrounding the fusion of gametes and the development of the fertilized ovum, nourishment and transport of the conceptus within the genital tract, implantation, embryogenesis, intrauterine growth, placentation and placental function, parturition, lactation and neonatal survival. Adverse reproductive effects in males will be considered as significant as adverse effects occurring in females. To provide a balanced presentation of approaches, equal emphasis will be given to clinical and animal or in vitro work. Typical end points that will be studied by contributors include infertility, sexual dysfunction, spontaneous abortion, malformations, abnormal histogenesis, stillbirth, intrauterine growth retardation, prematurity, behavioral abnormalities, and perinatal mortality.
