Lycopene modulates hepatic toxicity and testicular injury induced by etoposide in male rats.

OBJECTIVE

Lycopene (C40H56), a carotenoid found in red colour fruits, is known as a powerful antioxidant that protects cells from damage caused by reactive oxygen species (ROS). Etoposide inhibits topoisomerase II activity and restricts the development of cancer cells, though it establishes oxidative stress. To study the effect of lycopene (Ly) against hepatotoxicity and testis injury induced by etoposide in male rats.

ANIMALS

Forty male Wister albino rats.

SETTINGS

The experiment lasted for seven consecutive weeks including one week as acclimatization time.

DESIGN

The experiment was in a completely randomized design with a 2×2 factorial arrangement.

INTERVENTION(S): The animals were grouped as follow: No etoposide injection and no lycopene (control), lycopene supplementation (LY), etoposide injection (ET), and rats with etoposide injection and lycopene supplement (ET+LY).

MAIN OUTCOME MEASURE(S): At the end of the experiment, rats were sacrificed by cervical dislocation. Blood samples were harvested and analyzed for serum alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), low-density lipoprotein-Cholesterol (LDL-C), high-density lipoprotein-cholesterol (HDL-C), total cholesterol (TC), Total Protein (TP), glucose (GLU) and testosterone. The left testis was manipulated for histological examination.

RESULT(S): The result of experiment showed that rats with etoposide injection had higher ALT, AST, and ALP than the control rats. In contrast co-treated rats (ET+LY) significantly modulated the levels of the hepatic parameters. Administration of lycopene increased testosterone concentration and germinal epithelium of seminiferous tubules in testes rats.

CONCLUSION(S): Lycopene might be a promising agent with hepatoprotective effect in restoring testis injury induced by etoposide in rats.
