Evaluation of the molecular function of the HER2 receptor may be essential for the prognosis and targeted therapy of heart diseases. Keywords: Acute heart failure, HER2 receptor, Gene expression profile Introduction The ErbB family is composed of four plasma membrane-bound receptor tyrosine kinases, which are involved in molecular signaling related to cell growth and survival in many tumor types (Motoyama et al. 2002). The human epidermal growth factor receptor 2, known as HER2 (sometimes as Neu or ErbB2), is usually a member of this receptor family. Targeting the HER2 receptor is usually a milestone in the treatment of selected patients with early and advanced breast malignancy (Baselga et al. 2006; Nielsen et al. 2013). Anticancer efficacy is complicated by a new type of heart failure (Cheng and Pressure 2010; Perez 2008). There is evidence that trastuzumab (Criscitiello and Curigliano 2013; Procter et al. 2010; Russell et al. 2010), lapatinib (Perez et al. 2008a), and pertuzumab (Lenihan et al. 2012) blocking the ErbB2/HER2-dependent signaling pathway may lead to the deterioration of left ventricular cardiac function. Cardio-oncology, a new scientific discipline, aims at trying to find methods to prevent iatrogenic myocardial dysfunction during anticancer treatment (Curigliano et al. 2012; Opolski et al. 2011). The prevention of cardiotoxicity related to anti-HER2 treatment seems to be essential. On the other hand, cardiologists should be interested in what is the role of the molecular signaling pathway dependent on ErbB2/HER2 in patients with heart diseases. The primary aim of this study was to estimate the possible association between gene expression DR 2313 in the ErbB signaling pathway and selected clinical event data in patients with acute heart failure (AHF). Methods Patient characteristics The study enrolled 24 patients (19 males) with a history of heart disease who were admitted to the Cardiology Department of Warsaw Medical University or college with the diagnosis of AHF. The mean age of the patients was 68.6??12.3?years. The pre-existing heart diseases were: (1) myocardial infarction in 18 cases or (2) left ventricular hypertrophy with moderate mitral insufficiency in 6 situations. Before hospitalization, sufferers got received appropriate cardiological treatment: 18 had been treated with angiotensin-converting enzyme inhibitors, 17 with beta-blockers, 10 with diuretics, another 7 with aldosterone antagonists, 18 with antiplatelet therapy, and 20 with statins. The sources of AHF was decompensation from the circulatory program because of: myocardial ischemia (6), liquids overload in prior center failing (5), valve dysfunction deterioration (3), pulmonary infections (3), sudden boost of blood circulation pressure (3), myocarditis (2), and supraventricular arrhythmia with extremely fast ventricular price (2). The exclusion requirements had been: myocardial infarction with ST elevation being a reason behind AHF, pre-hospital cardiac arrest, pulmonary stroke or embolism, cancer or serious lung disease, and persistent kidney disease in prior history. All sufferers were treated and diagnosed based on the real suggestions from the Western european Culture of Cardiology. Upper body X-ray was performed in every sufferers to measure the amount of congestion in the lungs. The next laboratory tests had been performed in every from the individuals: complete bloodstream count number, serum sodium, potassium, urea, creatinine, albumin, liver organ enzymes, prothrombin period, and troponin. Doppler echocardiography was performed to judge the global and segmental systolic function from the still left and correct ventricles, diastolic ventricular function, morphology, and function from the center valves. The analysis was accepted by the neighborhood ethics committee from the Medical College or university of Warsaw and everything individuals gave written educated consent. RNA isolation, validation, labeling, and hybridization Bloodstream examples had been attracted after entrance towards the extensive treatment device simply, before you begin any treatment. These were extracted from the cephalic vein from the forearm, into PAXGene pipes (Qiagen, USA). Duplicate examples were extracted from each affected person. Total RNA from peripheral bloodstream nuclear cells was isolated utilizing a PAXgene Bloodstream RNA package (Qiagen, USA). Isolated RNA.Among both of these genes is ERBB2, with appearance sign below 0. Open in another window Fig. medically significant variables of sufferers with acute center failure.
