Ellagic Acid and Ellagic Acid Functionalized Selenium Nanoparticles Ameliorate Cyclophosphamide-Induced Testicular...

Area of Science:

• Reproductive Toxicology
• Nanomedicine
• Biochemistry

Background:

• Cyclophosphamide (CP) is a chemotherapy agent known to cause oxidative stress-mediated reproductive toxicity.
• Testicular injury induced by CP involves significant biochemical and histological damage.

Purpose of the Study:

• To investigate the prophylactic effects of ellagic acid (EA) and ellagic acid-functionalized selenium nanoparticles (EA-SeNPs) against CP-induced testicular injury in rats.
• To evaluate the potential of EA-SeNPs as a nano-formulation for reproductive protection.

Main Methods:

• Wistar rats were pretreated with varying doses of EA or EA-SeNPs before receiving a single dose of CP.
• Biochemical assays assessed oxidative stress markers, antioxidant enzyme activities, lipid metabolism, and sperm parameters.
• Testicular histology was examined to evaluate structural damage.

Main Results:

• CP exposure significantly increased lipid peroxidation, depleted glutathione (GSH), suppressed key antioxidant enzymes, elevated testicular cholesterol, and caused severe testicular degeneration.
• Prophylactic treatment with both EA and EA-SeNPs significantly ameliorated these CP-induced effects.
• EA-SeNPs demonstrated comparable protective efficacy to EA, highlighting their potential as a nano-formulation.

Conclusions:

• Ellagic acid and its functionalized selenium nanoparticles effectively mitigate cyclophosphamide-induced testicular injury.
• EA-SeNPs represent a promising nano-enabled intervention for reproductive protection by modulating oxidative stress and biochemical alterations.
• The study underscores the link between antioxidant imbalance and CP-induced testicular damage, supporting selenium-based nanotherapeutics.
