Implications of a Soy-Based Diet for Animal Models.

The use of animal models in fundamental or pre-clinical research remains an absolute requirement for understanding human pathologies and developing new drugs. In order to transpose these results into clinical practice, many parameters must be taken into account to limit bias. Attention has recently been focused on the sex, age or even strain of each animal, but the impact of diet has been largely neglected.

Overexpression of endothelial β -adrenergic receptor induces diastolic dysfunction in rats.

Aims: Diastolic dysfunction is common in cardiovascular diseases, particularly in the case of heart failure with preserved ejection fraction. The challenge is to develop adequate animal models to envision human therapies in the future. It has been hypothesized that this diastolic dysfunction is linked to alterations in the nitric oxide ( NO) pathway.

O-GlcNAc stimulation: A new metabolic approach to treat septic shock.

Septic shock is a systemic inflammation associated with cell metabolism disorders and cardiovascular dysfunction. Increases in O-GlcNAcylation have shown beneficial cardiovascular effects in acute pathologies. We used two different rat models to evaluate the beneficial effects of O-GlcNAc stimulation at the early phase of septic shock.

Human heart failure with preserved ejection versus feline cardiomyopathy: what can we learn from both veterinary and human medicine?

Cardiovascular affections are a growing health burden in human populations. Recent advances in cardiology have improved treatments and outcomes for myocardial infarction and arrhythmias, but other conditions still remain poorly understood. To date, the classical approach to study cardiovascular diseases involves rodent models, despite their strong differences with human cardiac physiology.
