Abstract

Preventive effects of ellagic acid against doxorubicin-induced cardiac oxidative, inflammatory and apoptotic stress were examined. This agent at 0.25, 0.5 or 1 % was added in feed and supplied to mice for 8 weeks, and followed by doxorubicin treatment. Ellagic acid intake increased its deposit in heart. Pre-intake of this compound at 0.5 and 1 % significantly attenuated doxorubicin caused increase in plasma creatine phosphokinase activity. Doxorubicin treatment decreased glutathione content, increased reactive oxygen species (ROS), malonyldialdehyde (MDA), interleukin (IL)-6, IL-10, monocyte chemoattractant protein-1 and tumor necrosis factor-alpha levels, declined glutathione peroxidase (GPX) and superoxide dismutase (SOD) activities, and enhanced xanthine oxidases (XO) activity in heart. Ellagic acid intake dose-dependently reserved glutathione content, lowered ROS and MDA levels, and reduced XO activity. This compound at 0.5 and 1 % retained GPX and SOD activities, and decreased cytokines in heart. Doxorubicin treatment raised cardiac activity and protein production of caspase-3, nuclear factor kappa B (NF-κB) p50 and p65. Ellagic acid dose-dependently lowered caspase-3 activity and cleaved caspase-3 formation, and at 0.5 and 1 % declined activity and protein level of NF-κB. Doxorubicin treatment also up-regulated cardiac expression of p-p38, p-ERK 1/2 and p-JNK, and ellagic acid at 0.5 and 1 % suppressed p-p38 expression and at 1 % down-regulated p-ERK 1/2 expression. These findings suggest that ellagic acid is a potent cardiac protective agent against doxorubicin.
