Abstract
Doxorubicin is one of the most important antitumor drugs used in oncology; however, its cardiotoxic effect limits the therapeutic use and raises concerns regarding patient prognosis. Leucine is a branched-chain amino acid used in dietary supplementation and has been studied to attenuate the toxic effects of doxorubicin in animals, which increases oxidative stress. Oxidative stress in different organs can be estimated using several methods, including catalase expression analysis. This study aimed to analyze the effect of leucine on catalase levels in rat hearts after doxorubicin administration. Adult male Wistar rats were separated into two groups: Standard diet (SD) and 5% Leucine-Enriched Diet (LED). The animals had free access to diet from D0 to D28. At D14, the groups were subdivided in animals injected with Doxorubicin and animals injected with vehicle, until D28, and the groups were SD, SD + Dox, LED and LED + Dox. At D28, the animals were submitted do Transthoracic Echocardiography and euthanized. Despite Dox groups had impaired body weight gain, raw heart weight was not different between the groups. No substantial alterations were observed in macroscopic evaluation of the heart. Although, Doxorubicin treatment increased total interstitial collagen in the heart, which in addition to Type I collagen, is lower in LED groups. Western blot analysis showed that catalase expression in the heart of LED groups was lower than that in SD groups. In conclusion, leucine supplementation reduced both the precocious Dox-induced cardiac remodeling and catalase levels in the heart.

What is considered cardiotoxicity of anthracyclines in animal studies. Oncol Rep 2020; 44:798-818.

Abstract
Anthracyclines are commonly used anticancer drugs with well-known and extensively studied cardiotoxic effects in humans. In the clinical setting guidelines for assessing cardiotoxicity are well-established with important therapeutic implications. Cardiotoxicity in terms of impairment of cardiac function is largely diagnosed by echocardiography and based on objective metrics of cardiac function. Until this day, cardiotoxicity is not an endpoint in the current general toxicology and safety pharmacology preclinical studies, although other classes of drugs apart from anthracyclines, along with everyday chemicals have been shown to manifest cardiotoxic properties. Also, in the relevant literature there are not well-established objective criteria or reference values in order to uniformly characterize cardiotoxic adverse effects in animal models. This in depth review focuses on the evaluation of two important echocardiographic indices, namely ejection fraction and fractional shortening, in the literature concerning anthracycline administration to rats as the reference laboratory animal model. The analysis of the gathered data gives promising results and solid prospects for both, defining anthracycline cardiotoxicity objective values and delineating the guidelines for assessing cardiotoxicity as a separate hazard class in animal preclinical studies for regulatory purposes.

Increased Dietary Leucine Reduces Doxorubicin-Associated Cardiac Dysfunction in Rats. Front Physiol 2018; 8:1042. [PMID: 29403386 PMCID: PMC5779071 DOI: 10.3389/fphys.2017.01042] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2017] [Accepted: 11/29/2017] [Indexed: 01/01/2023] Open
Abstract
Cardiotoxicity is one of the most significant adverse effects of the oncologic treatment with doxorubicin, which is responsible for a substantial morbid and mortality. The occurrence of heart failure with ventricular dysfunction may lead to severe cardiomyopathy and ultimately to death. Studies have focused on the effects of leucine supplementation as a strategy to minimize or revert the clinical condition of induced proteolysis by several clinical onsets. However, the impact of leucine supplementation in heart failure induced by doxorubicin is unknown. Therefore, the objective of this work is to evaluate the effects of leucine supplementation on the cardiotoxicity in the heart of rats treated with doxorubicin. Rats treated with a 7.5 mg/kg cumulative dose of doxorubicin for 14 days presented a dilatation of the left ventricle (LV), and a reduction of the ejection fraction (FE). The 5% supplementation of leucine in the rats' food prevented the malfunctioning of the LV when administered with doxorubicin. Some alterations in the extracellular matrix remodeling were confirmed by the increase of collagen fibers in the doxorubicin group, which did not increase when the treatment was associated with leucine supplementation. Leucine attenuates heart failure in this experimental model with doxorubicin. Such protection is followed by the maintenance of interstitial collagen fibers.
