Relationship between clinical data and gene expression in the HER2/ErbB2-dependent signaling pathway in patients with acute heart failure.

Anticancer treatment with the human epidermal growth factor receptor (HER) 2 inhibitors can lead to significant myocardial dysfunction. The primary aim of the study was to estimate the possible association between gene expression in the ErbB signaling pathway and selected clinical event data in patients with acute heart failure. Twenty-four patients (19 males), aged 68.

A retrospective study of clinical signs and epidemiology of chronic valve disease in a group of 207 Dachshunds in Poland.

Background: Chronic mitral valve disease is frequently seen in the Dachshund. Dachshunds (n=207) made up 11.73% of the dogs admitted to the Cardiology Service at the Small Animal Clinic, Warsaw University of Life Sciences, Poland (first visits only).

White blood cell transcriptome correlates with renal function in acute heart failure.

It is notoriously difficult to classify patients with acute heart failure (AHF) because of variations in clinical presentation, different etiologies, the impact of comorbidities, and variable prognoses. In this study, we used DNA whole-genome microarrays to classify 24 patients with AHF based on the transcriptome of their peripheral blood nuclear cells. The main purpose was to verify whether any transcriptomic sub-clusters had clinical correlations.

Genomic and genetic aspects of heart failure in dogs - a review.

The most common causes of heart failure in dogs are valvular disease, predominantly endocardiosis, and myocardial disease, predominantly dilated cardiomyopathy. They are related to changes in the expression of several genes in the heart muscle and in peripheral blood nuclear cells which could be considered as prognostic or diagnostic markers of heart disease in dogs. Since many human genetic markers of heart failure have turned out to be useless in dogs, the screening for genomic markers of canine heart failure could give more insight into the molecular pathology of these diseases and aid the development of new treatment strategies.
