  • Title: Dietary trans fats enhance doxorubicin-induced cardiotoxicity in mice.
    Author: Mong MC, Hsia TC, Yin MC.
    Journal: J Food Sci; 2013 Oct; 78(10):H1621-H1628. PubMed ID: 24024564.
    Abstract:
    This study investigated the combined effects of trans fat diet (TFD) and doxorubicin upon cardiac oxidative, inflammatory, and coagulatory stress. TFD increased trans fatty acid deposit in heart (P < 0.05), and decreased protein C and antithrombin-III activities in circulation (P < 0.05). TFD plus doxorubicin treatment elevated activities of plasminogen activator inhibitor-1, lactate dehydrogenase, and creatine phosphokinase (P < 0.05). This combination also raised xanthine oxidase activity, and enhanced cardiac levels of reactive oxygen species, interleukin (IL)-6, IL-10, tumor necrosis factor-alpha, and monocyte chemoattractant protein-1 than TFD or doxorubicin treatment alone (P < 0.05). TFD alone increased cardiac nuclear factor kappa B (NF-κB) activity (P < 0.05), but failed to affect expression of NF-κB and mitogen-activated protein kinase (MAPK) (P > 0.05). Doxorubicin treatment alone augmented cardiac activity, mRNA expression, and protein production of NF-κB and MAPK (P < 0.05). TFD plus doxorubicin treatment further upregulated cardiac expression of NF-κB p65, p-p38, and p-ERK1/2 (P < 0.05). These findings suggest that TFD exacerbates doxorubicin-induced cardiotoxicity.
