Protective effect of omega-3 on reducing doxorubicin toxicity in preclinical trials

The use of chemotherapeutic agents, such as doxorubicin, is often associated with severe adverse effects, making it essential to develop therapeutic strategies that can attenuate or reduce their toxicity. This study aimed to investigate the effects of omega-3 in mitigating the damage induced by doxorubicin. Rabbits received doxorubicin (1 mg/kg, twice weekly for six weeks) with or without omega-3 (500, 1000, or 2000 mg/kg), administered concomitantly. An additional group received omega-3 alone (2000 mg/kg). Hematological, biochemical, genotoxic (micronucleus assay), cardiological (electrocardiogram, echocardiogram, and markers), and histopathological parameters were assessed. Os resultados mostraram que o tratamento com doxorrubicina isolada induziu caquexia nos animais. O tratamento com ômega-3 melhora parâmetros como ganho de peso, fração de ejeção cardíaca, encurtamento sistólico ventricular, marcadores cardíacos CK-MB e Troponina I, área do ventrículo esquerdo e parâmetros histopatológicos (inflamação, edema, dano celular e fibras musculares), sugerindo um efeito protetor. Além disso, o ômega-3 exibiu atividade antigenotóxica, evidenciada pela redução de micronúcleos. Esses achados indicam que o ômega-3 pode servir como um complemento eficaz à quimioterapia, reduzindo a toxicidade da doxorrubicina.

Abstract

The use of chemotherapeutic agents, such as doxorubicin, is often associated with severe adverse effects, making it essential to develop therapeutic strategies that can attenuate or reduce their toxicity. This study aimed to investigate the effects of omega-3 in mitigating the damage induced by doxorubicin. Rabbits received doxorubicin (1 mg/kg, twice weekly for six weeks) with or without omega-3 (500, 1000, or 2000 mg/kg), administered concomitantly. An additional group received omega-3 alone (2000 mg/kg). Hematological, biochemical, genotoxic (micronucleus assay), cardiological (electrocardiogram, echocardiogram, and markers), and histopathological parameters were assessed. Os resultados mostraram que o tratamento com doxorrubicina isolada induziu caquexia nos animais. O tratamento com ômega-3 melhora parâmetros como ganho de peso, fração de ejeção cardíaca, encurtamento sistólico ventricular, marcadores cardíacos CK-MB e Troponina I, área do ventrículo esquerdo e parâmetros histopatológicos (inflamação, edema, dano celular e fibras musculares), sugerindo um efeito protetor. Além disso, o ômega-3 exibiu atividade antigenotóxica, evidenciada pela redução de micronúcleos. Esses achados indicam que o ômega-3 pode servir como um complemento eficaz à quimioterapia, reduzindo a toxicidade da doxorrubicina.
