Background—Detailed understanding of regional function after myocardial infarction (MI) is currently incomplete. We aimed at investigating regional myocardial strain and work in post-MI rats with and without heart failure. Methods and Results—Six weeks …

Mitochondrial ATP synthase catalyzes the coupling of oxidative phosphorylation. Under pathological conditions, ATP synthase hydrolyzes ATP to replenish protons from the matrix into the intermembrane space, sustaining mitochondrial membrane potential. …

Objective: This study is to investigate the effect of β-adrenergic receptor kinase inhibitor (Adeno-βARKct) on heart failure (HF) rat model. Methods: Male SD rats weighted 250 g undertaken ligation of the left anterior de- scending branch of coronary …

Aortic valve (AoV) calcification is common in aged populations. Its subsequent aortic stenosis has been linked with increased morbidity, but still has no effective pharmacological intervention. Our previous data show endoplasmic reticulum (ER) stress is …

Dipeptidyl peptidase 4 inhibitors are used worldwide in the management of diabetes, but their role in the prevention or treatment of cardiovascular disorders has yet to be defined. We found that linagliptin, a DPP-4 inhibitor, suppressed capillary …

Background: Patients with heart failure (HF) display erectile dysfunction (ED). However, the pathophysiology of ED during HF remains poorly investigated. Objective: This study aimed to characterize the aortocaval fistula (ACF) rat model associated with HF …

Immunoglobulin E (IgE) has been suggested as a risk factor for allergy-induced low blood pressure, which has not been well explained in molecular details. Our current study shows a novel mechanism involving IgE, FcɛR1, miRNA-212-5p (miR-212-5p), and …

Transient receptor potential vanilloid 4 (TRPV4) is highly expressed in heart and vessels and can be activated during myocardial ischemia/reperfusion (I/R). Recently, we found that treatment with a selective TRPV4 antagonist HC-067047 significantly …

Aim: An increased density of intraplaque (IP) microvessels in ruptured versus nonruptured human plaques suggests that IP neovascularization has a major causative effect on plaque development and instability. Possibly, vascular endothelial growth factor …

MicroRNAs (miRNAs) have been identified as important players in the pathogenesis of cardiac hypertrophy. In the present study, we evaluated the potential role of miR-138 in cardiac hypertrophy and the potential molecular mechanisms. We observed that in …
