Therapeutic role of Annona muricata fruit and bee venom against MNU-induced breast cancer. - GreenMedInfo Summary

Aim: To evaluate the potential therapeutic role of(graviola) fruit and bee venom (BV) against-methylnitrosourea (MNU)-induced breast cancer in pregnant female rats and complications in the ovaries.

Methods: A total of 24 female rats were induced with a single dose of MNU (50 mg/kg body weight). After confirmation of positive tumor marker, female rats were placed with the males for mating. The pregnant rats were randomly divided into four groups (n=6): MNU-induced only (group 1), MNU-induced rats and supplemented with200 mg/kg diet (group 2), MNU-induced and treated with two doses of BV 75μg/kg (group 3), and MNU-induced and treated with bothand BV (group 4).

Results: In group 1, the breast tissue of mothers revealed pronounced cellular hyperplasia and histopathological signs. Also, the ovarian tissue of mothers and their offspring displayed deleterious histological changes. In groups 2 and 4, histopathological signs and cellular hyperplasia markedly disappeared in breast tissue. However, the histopathological signs induced by MNU in the ovarian tissue reversed to normal in groups 2-4. Also in groups 2-4, levels of serum MMP1, NFκB, and TNFα significantly decreased, and serum caspase 3 significantly increased either in mother rats or their offspring compared to the MNU-alone group. Levels of serum MDA significantly decreased; however, levels of serum antioxidants (CAT and SOD) significantly increased in all groups 2-4 compared to MNU-alone group.

Conclusion: has a more powerful therapeutic role than BV against MNU-induced breast cancer in rats; however, both have a powerful ameliorative role against ovarian histopathological alterations induced by MNU. Such ameliorative effects ofand BV are mainly attributed to their antioxidant, anti-inflammatory, and antiproliferative constituents.
