Effect of curcumin and cacao extract on interleukin-6 expression on ribociclib-induced hepatotoxicity in rats
Abstract
Purpose: To assess the relationship between interleukin-6 (IL-6) expression and the protective effect of curcumin and cacao extract on hepatotoxicity caused by ribociclib.
Method: Sixty adult male albino rats (9 – 10 weeks old) were utilized in this experiment. The rats were separated into six groups (n = 10 each). Group 1 (control) rats received 2 mL of normal saline daily. Group 2 rats were administered 5 mg/kg ribociclib and group 3 rats received 5 mg/kg ribociclib with a cacao dose of 200 mg/kg daily. Group 4 rats were administered 5 mg/kg ribociclib treated with curcumin (200 mg/kg) daily. Groups 5 and 6 were administered cacao and curcumin doses of 200 mg/kg daily. All rats were sacrificed and liver immunohistochemical and histological examinations were performed.
Result: The findings demonstrated that ribociclib administration caused liver damage and morphological changes at a histological level in liver tissue. The immunohistochemical investigation revealed that IL-6 levels were significantly increased in group 2 and control group (p < 0.05). Furthermore, co-administration of curcumin and cacao with ribociclib suppressed the levels of IL-6 expression in the liver tissue of rats compared to control group 1.
Conclusion: Co-administration of curcumin and cacao protects the liver against ribociclib-induced liver damage. It is necessary to determine the effect of long-term administration of these extracts on the functions of some organs such as the liver and kidney.
