Chronic moderate‑intensity exercise can induce physiological hypertrophy in aged cardiomyocytes through autophagy, with minimal Yap/Taz involvement.
Biomed Rep

Physiology Molecular, Biological Activity Division, Central Laboratory, Sumedang, West Java 45363, Indonesia.
Aging is known to cause increased comorbidities associated with cardiovascular decline. Physical exercises were known to be an effective intervention for the age-associated decline in cardiac function. Exercise caused physiological hypertrophy influenced by Yap/Taz, autophagy and myosin heavy chain (MHC) dynamics.

Introduction: Hypertrophic cardiomyopathy (HCM) is a common genetic heart disorder. It is characterized by left ventricular hypertrophy and impaired cardiac function, with forms categorized into obstructive (oHCM) and nonobstructive (nHCM). Traditional treatments address symptoms but not the underlying disease mechanism, highlighting the need for novel therapies.

Microplastics (MPs) have been found to interfere with the gut microbiota and compromise the integrity of the gut barrier. Excessive exposure to MPs markedly elevates the risk of cardiovascular disease, yet their influence on hypertension remains elusive, calling for investigation into their potential impacts on blood pressure (BP) regulation. In the present study, an increase in the concentration of MPs was observed in the fecal samples of individuals suffering from hypertension, as compared to the controls.

This study aimed to investigate the correlation of the increased volume index of epicardial adipose tissue (EAT) and left ventricular hypertrophy (LVH) in patients with Hypertension (HTN). A total of 209 HTN patients and 50 healthy controls, who underwent cardiovascular magnetic resonance (CMR) at two medical centers in China between June 2015 and October 2024, were enrolled for this study. Postprocessing and imaging analysis were conducted and EAT measurements were performed.

Objective: To study the effect of Dapagliflozin on ferroptosis in rabbits with chronic heart failure and to reveal its possible mechanism.
Methods: Nine healthy adult male New Zealand white rabbits were randomly divided into Sham group (only thorax opening was performed in Sham group, no ascending aorta circumferential ligation was performed), Heart failure group (HF group, ascending aorta circumferential ligation was performed in HF group to establish the animal model of heart failure), and Dapagliflozin group (DAPA group, after the rabbit chronic heart failure model was successfully made in DAPA group). Dapagliflozin was given by force-feeding method.
