Aldehyde dehydrogenase 2 activation ameliorates cyclophosphamide-induced acute cardiotoxicity via detoxification of toxic aldehydes and suppression of cardiac cell death. J Mol Cell Cardiol 2018; 121:134-144. [PMID: 29981795 DOI: 10.1016/j.yjmcc.2018.07.006] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/02/2018] [Revised: 06/03/2018] [Accepted: 07/04/2018] [Indexed: 01/27/2023]
Abstract
Cyclophosphamide (CY)-induced acute cardiotoxicity is a common side effect which is dose dependent. It is reported that up to 20% of patients received high dose of CY treatment suffered from acute cardiac dysfunction. However, the effective intervention strategies and related mechanisms are still largely unknown. We aimed to investigate the effects of aldehyde dehydrogenase 2 (ALDH2), an important endogenous cardioprotective enzyme, on CY-induced acute cardiotoxicity and the underlying mechanisms. It was found that ALDH2 knockout (KO) mice were more sensitive to CY-induced acute cardiotoxicity, presenting as higher serum levels of creatine kinase-MB isoform and lactate dehydrogenase, and significantly reduced myocardial contractility compared with C57BL/6 (WT) mice. In addition, cardiac cell death, especially necrosis, was obviously increased in ALDH2 KO mice compared with WT mice after CY treatment. Furthermore, accumulation of toxic aldehydes such as acrolein and 4-HNE and reactive oxygen species (ROS) in the myocardium were significantly elevated after CY in ALDH2 KO mice. Importantly, ALDH2 activation by Alda-1 pretreatment markedly attenuated CY-induced accumulation of toxic aldehydes, cardiac cell death and cardiac dysfunction, without affecting CY's anti-tumor efficacy. In conclusion, the cardioprotective effects of ALDH2 activation against CY-induced acute cardiotoxicity are exerted via reducing toxic aldehydes accumulation and potentially interrupting the acrolein-ROS-aldehydes vicious circles, and thus alleviates myocardial cell death, without antagonizing the anti-tumor efficacy of CY. Therefore, ALDH2 might be a promising prevention and treatment target for CY-induced acute cardiotoxicity.

Abstract
We sought to explore the effect of blueberry anthocyanins-enriched extracts (BAE) on cyclophosphamide (CTX)-induced cardiac injury. The rats were divided randomly into five groups including normal control, CTX 100 mg/kg, BAE 80mg/kg, CTX+BAE 20mg/kg and CTX+BAE 80mg/kg groups. The rats in the three BAE-treated groups were administered BAE for four weeks. Seven days after BAE administration, rats in CTX group and two BAE-treated groups were intraperitoneally injected with a single dose of 100 mg/kg CTX. Cardiac injury was assessed using physiological parameters, Echo, morphological staining, real-time PCR and western blot. In addition, cardiotoxicity indices, inflammatory cytokines expression and oxidative stress markers were also detected. Four weeks 20mg/kg and 80mg/kg dose of BAE treatment following CTX exposure attenuated mean arterial blood pressure, heart rate and activities of heart enzymes, improved cardiac dysfunction, left ventricular hypertrophy and fibrosis. Importantly, BAE also attenuated CTX-induced LV leukocyte infiltration and inflammatory cytokines expression, ameliorated oxidative stress as well as cardiomyocyte apoptosis. In conclusion, BAE attenuated the CTX-induced cardiac injury and the protective mechanisms were related closely to the anti-inflammatory, antioxidant and anti-inflammatory characteristics of BAE.

Asiri YA. Probucol attenuates cyclophosphamide-induced oxidative apoptosis, p53 and Bax signal expression in rat cardiac tissues. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2010; 3:308-16. [PMID: 21150336 PMCID: PMC3154034 DOI: 10.4161/oxim.3.5.13107] [Citation(s) in RCA: 70] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/26/2010] [Revised: 07/20/2010] [Accepted: 07/21/2010] [Indexed: 11/19/2022]
Abstract
Cyclophosphamide (CP) is a widely used in cancer chemotherapy and immunosuppression, which could cause toxicity of the normal cells due to its toxic metabolites. Probucol, cholesterol-lowering drug, acts as potential inhibitor of DNA damage and shows to protect against doxorubicin-induced cardiomyopathy by enhancing the endogenous antioxidant system including glutathione peroxidase, catalase and superoxide dismutase. This study examined the possible protective effects of probucol, a lipid-lowering compound with strong antioxidant properties, against CP-induced cardiotoxicity. This objective could be achieved through studying the gene expression-based on the possible protective effects of probucol against CP-induced cardiac failure in rats. Adult male Wistar albino rats were assigned into 4 treatment groups: Animals in the first (control) and second (probucol) groups were injected intraperitoneally with corn oil and probucol (61 mg/kg/day), respectively, for two weeks. Animals in the third (CP) and fourth (probucol plus CP) groups were injected with the same doses of corn oil and probucol (61 mg/kg/day), respectively, for one week before and one week after a single dose of CP (200 mg/kg, I.P.). The p53, Bax, Bcl2 and oxidative genes signal expression were measured by real time PCR. CP-induced cardiotoxicity was clearly observed by a significant increase in serum creatine phosphokinase isoenzyme (CK-MB) (117%), lactate dehydrogenase (LDH) (64%), free (69%) and esterified cholesterol (42%) and triglyceride (69%) compared to control group. In cardiac tissues, CP significantly increases the mRNA expression levels of apoptotic genes, p53 with 2 folds and Bax with 1.6 fold, and decreases the anti-apoptotic gene Bcl2 with 0.5 fold. Moreover, CP caused down-regulation of antioxidant genes, glutathione peroxidase, catalase, and superoxide dismutase and increased the lipid peroxidation and decreased adenosine triphosphate (ATP) (40%) and ATP/ADP (44%) in cardiac tissues. Probucol pretreatment not only counteracted significantly the CP-induced increase in cardiac enzymes and apoptosis but also it induced a significant increase in mRNA expression of antioxidant enzymes and improved ATP, ATP/ADP, glutathione (GSH) in cardiac tissues. In conclusion, data from the present study suggest that probucol prevents the development of CP-induced cardiotoxicity by a mechanism related, at least in part, to its ability to increase mRNA expression of antioxidant genes and to decrease apoptosis in cardiac tissues with the consequent improvement in mitochondrial oxidative phosphorylation and energy production.
