0131 : Impact of overweight on anthracycline and trastuzumab-induced cardiotoxicity: experimental study in mice
Trastuzumab (TRZ), a humanized monoclonal antibody against Human Epidermal Growth Factor Receptor 2 (HER2) oncogene, is believed to potentiate doxorubicin (DOX) cardiotoxicity, resulting in left ventricular dysfunction. Few data indicate that overweight could influence DOX-induced cardiotoxicity, and no study has already evaluated the impact of moderate overweight on the cardiotoxic effect of DOX alone or in combination with TRZ. Immediately after birth, litters of C57BL/6 mice were either maintained at 10 (normal litter, NL), or reduced to 3 (small litter, SL) in order to induce programming of ~15% overweight through postnatal overfeeding. At 4 months, in order to evaluate the potentiation…
0004 : Overweight in mice induced by perinatal programming exacerbates doxorubicin and trastuzumab cardiotoxicity
Background Trastuzumab (TRZ) is believed to potentiate doxorubicin (DOX) cardiotoxicity, resulting in left ventricular dysfunction. There is some evidence that overweight could influence anticancer drug-induced cardio \toxicity, though no study has evaluated the impact of moderate overweight, induced by postnatal nutritional programming, on the cardiotoxic effects of DOX alone or in combination with TRZ. Methods Immediately after birth, litters of C57BL/6 mice were either maintained at 9 pups (normal litter, NL), or reduced to 3 (small litter, SL) in order to induce programming of ~15% overweight through postnatal overfeeding. At 4 months, NL and SL mice received a single intraperitoneal in…
