Positive Roles of Resveratrol in Early Development of Testicular Germ Cells against Maternal Restraint Stress in Mice

Abstract

Our present study was designed to evaluate the effects of resveratrol (RES) in Swiss mice by exposing them to prenatal stress. Twenty-four Swiss mice were divided into four groups: control (C), maternal restraint stress (MRS), maternal restraint stress + resveratrol (MRS + RES) 2 mg, and maternal restraint stress + resveratrol (MRS + RES) 20 mg. Dams were exposed to stress by restraint in plastic tubes for four hours a day from 12–18 days of gestation. The results showed that male pups of MRS were significantly decreased in the testis weight, anogenital distance, area of seminiferous tubules, diameter of seminiferous tubules, area of the lumen, diameter of the lumen, and epithelial height of seminiferous tubules. However, the anomalies of the reproductive tract produced under restraint stress were neutralized by the use of RES 2 mg/kg. A significant difference was observed between terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)- positive germ cells in MRS and MRS + RES 20 mg/kg groups, while it was non-significant between MRS + RES 2 mg/kg and C groups. Apart from these effects, blood glucose levels were increased in MRS and MRS + RES 20 mg/kg groups, while experimental animals of the MRS + RES 2 mg/kg group significantly recovered. These results suggested that a lower dose of RES could cure the adverse effects of prenatal stress in early age male progeny. Thus, our study suggests, for the first time, practical values for a lower dose of RES 2 mg/kg as a safe and effective agent in the first week age of prenatally stressed mice.

“…Accordingly, natural antioxidants should be included as an essential factor in poultry nutrition for enhancing immunity to increase production [ 3 ]. Antioxidants are widely used, and there are many studies demonstrating that antioxidants can play a protective role in animal production and reproduction, stress, immune system, antioxidant status, inflammation, disease prevention, and improve all over health [ 9 , 10 , 11 , 12 , 13 ].…”

Resveratrol Enhances the Radiosensitivity by Inducing DNA Damage and Antitumor Immunity in a Glioblastoma Rat Model under 3 T MRI Monitoring

“…Resveratrol, a polyphenolic compound extracted from natural plants such as grapes, peanuts, and mulberries, can weaken the growth of various human and rat tumors cells both in vitro and in vivo [ 14 ]. Unlike most anticancer drugs, the anticancer dose of resveratrol has no adverse effects on the growth of normal cells and the function of tissues and organs, suggesting that it is safe to be used alone or in combination with other treatments [ 15 ]. More importantly, resveratrol can be utilized as a radiosensitizer in the treatment of cancers, including GBM [ 16 ].…”
