Cardiomyocyte proliferation and heart regeneration in adult Xenopus tropicalis evidenced by a transgenic reporter line.

NPJ Regen Med

December 2024

Key Laboratory of Regenerative Medicine of Ministry of Education, Institute of Aging and Regenerative Medicine, Department of Developmental & Regenerative Biology, College of Life Science and Technology, Department of Cardiology, The Affiliated Guangdong Second Provincial General Hospital, Jinan University, Guangzhou, 510632, China.

Cardiomyocyte proliferation in adult Xenopus tropicalis during heart regeneration has remained largely contentious due to the absence of genetic evidence. Here, we generated a transgenic reporter line Tg(mlc2:H2C) expressing mCherry specifically in cardiomyocyte nuclei driven by the promoter of myosin light chain 2 (mlc2). Using the reporter line, we found that traditional whole-cell staining is not a rigorous way to identify cardiomyocytes in adult Xenopus tropicalis when using a cryosection with common thickness (5 μm) which leading to a high error, but this deviation could be reduced by increasing section thickness.

Increased cardiac myosin super-relaxation as an energy saving mechanism in hibernating grizzly bears.

Mol Metab

December 2024

Department of Biomedical Sciences, University of Copenhagen, Copenhagen, Denmark; Myocardial Homeostasis and Cardiac Injury Program, Centro Nacional de Investigaciones Cardiovasculares (CNIC), Madrid, Spain. Electronic address:

Aim: The aim of the present study was to define whether cardiac myosin contributes to energy conservation in the heart of hibernating mammals.

Methods: Thin cardiac strips were isolated from the left ventricles of active and hibernating grizzly bears; and subjected to loaded Mant-ATP chase assays, X-ray diffraction and proteomics.

Main Findings: Hibernating grizzly bears displayed an unusually high proportion of ATP-conserving super-relaxed cardiac myosin molecules that are likely due to altered levels of phosphorylation and rod region stability.

The clinical utility of cardiac myosin inhibitors for the management of hypertrophic cardiomyopathy: a scoping review.

Heart Fail Rev

December 2024

Division of Cardiovascular Medicine, University of Virginia, 1215 Lee St Box 800158, Charlottesville, VA, 22908, USA.

Hypertrophic cardiomyopathy (HCM) is an inherited condition characterized by left ventricular, non-dilated hypertrophy in the absence of another secondary underlying cause. There has been an ongoing increase in the diagnosis of HCM over the past couple of decades, prompting further work in the area of pharmacological and interventional therapies. This scoping review aimed to summarize the traditional therapeutic options for HCM and to explore emerging research on novel cardiac myosin inhibitors (CMIs) as a new option for pharmacologic management of HCM.

Recreational and Occupational Physical Activity and Risk of Adverse Events in Truncating Founder Variant Carriers.

December 2024

Department of Cardiology (M.J., L.P.B., A.F.S., D.v.d.S., A.S.J.M.t.R.), University Medical Center Utrecht, Utrecht University, the Netherlands.

Background: founder variants cause hypertrophic cardiomyopathy leading to heart failure and malignant ventricular arrhythmias. Exercise is typically regarded as a risk factor for disease expression although evidence is conflicting. Stratifying by type of exercise may discriminate low- from high-risk activities in these patients.
