Improvements in diagnosis and treatments explain the notable increase in patients chronically affected or recovering from cancer. This is a fragile population, who is physically, psychologically and socially affected by the consequences of the disease and the associated treatments. In addition to detecting a possible relapse, oncologists and primary care physicians have to deal with a variety of issues like psychological distress, sexual dysfunction, cardiotoxicity, cognitive impairment, fatigue and, in some cases, a second primary cancer...

Doxorubicin (DOX) is an anthracycline anti-tumor drug. However, its clinical use is limited by dose-dependent cardiotoxicity, and even progresses to chronic heart failure (CHF). OBJECTIVE: This study aims to investigate whether the Nrf2 activator, sulforaphane (SFN), can prevent DOX-induced CHF. METHODS: Male Sprague Dawley rats who received treatment for six weeks were divided into four groups (n=30 per group): control, SFN, DOX, and DOX plus SFN group. RESULTS: Results revealed that DOX induced progressive cardiac damage as indicated by increased cardiac injury markers, cardiac inflammation, fibrosis and oxidative stress...

Epithelial-mesenchymal transition (EMT) has been implicated in tumor invasion and metastasis and provides novel strategies for cancer therapy. Hypaconitine (HpA), a diester-diterpenoid alkaloid isolated from the root of the Aconitum species, exhibits anti-inflammatory, analgesic, and especially, cardiotoxic activities. Here, we reported the anti-metastatic potentials of HpA in transforming growth factor-β1 (TGF-β1)-induced EMT in lung cancer A549 cells. The cytotoxic effect of HpA was determined by MTT assay...

BACKGROUND: The overexpression of human epidermal growth factor receptor-2 (HER2) in breast cancer is a poor prognosis. Trastuzumab improves overall survival but is associated with cardiotoxicity, especially a decline in left ventricular ejection fraction (LVEF). In addition, chemotherapy and radiotherapy increase fatigue and pain, decrease physical capacity and health-related quality of life. To date, no study has evaluated the benefits of physical activity on the side effects of treatment in patients with HER2 positive breast cancer...

The use of engineered cardiac tissue for high-throughput drug screening/toxicology assessment remains largely unexplored. Here we propose a scaffold that mimics aspects of cardiac extracellular matrix while preserving the contractility of cardiomyocytes. The scaffold is based on a poly(caprolactone) (PCL) nanofilm with magnetic properties (MNF, standing for magnetic nanofilm) coated with a layer of piezoelectric (PIEZO) microfibers of poly(vinylidene fluoride-trifluoroethylene) (MNF+PIEZO). The nanofilm creates a flexible support for cell contraction and the aligned PIEZO microfibers deposited on top of the nanofilm creates conditions for cell alignment and electrical stimulation of the seeded cells...

We tested the hypothesis that aerobic exercise training (AET) would modulate doxorubicin-induced cardiotoxicity in rats of various ages. Wistar male rats (n = 72) were assigned to three groups (young, adult, and elderly) with three subgroups for each age: doxorubicin (DG, n = 8), AET + doxorubicin (AETDG, n = 8), AET + Saline (AETSG, n = 8). Following the AET intervention, rats were anesthetized and killed to collect heart tissues in order to determine heat shock protein 70 (HSP70), superoxide dismutase (SOD), malondialdehyde (MDA), interleukin-10 (IL10), and c-reactive protein (CRP)...

The use of doxorubicin (DOXO) as a chemotherapeutic drug has been hampered by cardiotoxicity leading to cardiomyopathy and heart failure. Folic acid (FA) is a modulator of endothelial nitric oxide (NO) synthase (eNOS), which in turn is an important player in diseases associated with NO insufficiency or NOS dysregulation, such as pressure overload and myocardial infarction. However, the role of FA in DOXO-induced cardiomyopathy is poorly understood. The aim of this study was to test the hypothesis that FA prevents DOXO-induced cardiomyopathy by modulating eNOS and mitochondrial structure and function...

Breast cancer is one of the most commonly diagnosed types of cancer in women. Its pathogenesis involves genetic, hormonal, and environmental factors. A large body of evidence indicates that physical activity has positive effects on every aspect of breast cancer evolution, including prevention, medical treatment, and aftercare clinical settings. Thus, different types of exercise can influence the prevention and progression of the disease through several common mechanisms, such as reduction of insulin resistance and improvement of immunity and cardiovascular function...

Anthracycline drugs such as doxorubicin (DOX) and daunorubicin remain some of the most active wide-spectrum and cost-effective drugs in cancer therapy. However, colorectal cancer (CRC) cells are inherently resistant to anthracyclines which at higher doses cause cardiotoxicity. Our recent studies indicate that aldose reductase (AR) inhibitors such as fidarestat inhibit CRC growth in vitro and in vivo. Here, we show that treatment of CRC cells with fidarestat increases the efficacy of DOX-induced death in HT-29 and SW480 cells and in nude mice xenografts...

Since its approval in 1979 cisplatin has become one of the most extensively used chemotherapeutics in the clinic and although cell resistance and toxicity hinder its efficacy it continues to be a gold standard regimen. Cisplatin's side effects primarily include nephrotoxicity, gastrointestinal toxicity, neurotoxicity and ototoxicity. Cardiotoxicity is generally not defined as a side effect of cisplatin. However, over the past decade there has been a surge in the amount of clinical cases reporting a vast array of cardio-toxic events occurring during or shortly after cisplatin infusion, these range from angina to cardiac ischemia and chronic heart failure...

Arsenic is a widespread metalloid in the environment, which poses a broad spectrum of adverse effects on human health. However, a global view of arsenic-induced heart toxicity is still lacking, and the underlying molecular mechanisms remain unclear. By performing a comparative quantitative proteomic analysis, the present study aims to investigate the alterations of proteome profile in rat heart after long-term exposure to arsenic. As a result, we found that the abundance of 81 proteins were significantly altered by arsenic treatment (35 up-regulated and 46 down-regulated)...

It is currently recommended that hydroxychloroquine (HCQ) be maintained during pregnancy in patients with systemic lupus erythematosus. Recent data suggest that this Toll-like receptor inhibitor may also reduce the recurrence rate of anti-SSA/Ro associated congenital heart block (CHB). This case report describes a unique situation in which a CHB-afflicted, HCQ-exposed pregnancy was electively terminated. The heart did not reveal any characteristic features of cardiotoxicity, providing further evidence supporting the safety of foetal exposure to HCQ...
