Background: Despite its usefulness as an antineoplastic agent, doxorubicin (DOX) has been associated with the
development of acute and chronic cardiotoxicity.
Aim: The present study for the first time was undertaken to evaluate and compare the potential antitumoral
effects of three drugs; (captopril, rosuvastatin and omega 3) in combination with DOX against diethyl nitrosamine
(DEN)-induced hepatocellular (HCC) in mice, in an attempt to achieve an improved antitumoral effect devoid of
cardiotoxicity.
Methods: The effect of combined treatments was evaluated by analyzing cell viability in vitro, studying tumor
apoptosis (Bcl-X and Bak) and angiogenesis (VEGF) in vivo, assessing cardiac inflammation (TNF-α ) and oxidative
stress (MDA,GSH, SOD), and evaluating variations of heart weight/body weight ratio as a general indicator of animal
health status. Histopathological assessement of liver and heart were also performed.
Results: Compared to the DEN group, administration of doxorubicin (12 mg/kg ip) resulted in a significant
increment in Bak expression and a significant decrease of hepatic VEGF level. Furthermore, captopril (25 mg/kg,
po), rosuvastatin (20 mg/kg, po) and omega-3 (1gm/kg, po) treated groups were shown to have more pronounced
reduction of hepatic VEGF measured. Marked cardio protection was noticed with the combination regimen.
Conclusion: The antitumoral, apoptotic and anti-angiogenic effects demonstrated by the combined treatment with
rosuvastatin, captopril or omega 3 and DOX, is further emphasized by lack of toxicity. The most promising results
were obtained with rosuvastatin and captopril treatment. These data raise important issues that may impact how
these drugs can best be included in chemotherapy regimens.
