Targeted Anti‐IL‐1 Immunomodulatory Therapy in Pediatric Onset PPP1R13L‐Related Arrhythmogenic Cardiomyopathy

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Autosomal recessive loss‐of‐function variants in PPP1R13L cause an ultra‐rare cardiocutaneous syndrome characterized by rapidly progressive arrhythmogenic cardiomyopathy (ACM). PPP1R13L encodes iASPP, which has two potentially overlapping mechanisms driving ACM as both a regulator of NFκB‐mediated inflammation and a binding partner within the ...

ATP-Sensitive Potassium Channel Currents in Eccentrically Hypertrophied Cardiac Myocytes of Volume-Overloaded Rats

International Journal of Cell Biology, 2011
ATP-sensitive potassium channels (KATP) protect the myocardium from hypertrophy induced by pressure-overloading. In this study, we determined the effects of these channels in volume-overloading.

It takes two to tango: cardiac fibroblast-derived NO-induced cGMP enters cardiac myocytes and increases cAMP by inhibiting PDE3

Communications Biology, 2023
The occurrence of NO/cGMP signalling in cardiac cells is a matter of debate. Recent measurements with a FRET-based cGMP indicator in isolated cardiac cells revealed NO-induced cGMP signals in cardiac fibroblasts while cardiomyocytes were devoid of these ...

From Millimeters to Micrometers; Re-introducing Myocytes in Models of Cardiac Electrophysiology

Frontiers in Physiology, 2021
Computational modeling has contributed significantly to present understanding of cardiac electrophysiology including cardiac conduction, excitation-contraction coupling, and the effects and side-effects of drugs.

Evaluation of cardiac histology and cell death markers during the progression of diabetes in a streptozotocin‐induced diabetes rat model

Animal Models and Experimental Medicine, EarlyView.
Daily insulin administration in streptozotocin‐induced diabetic rats prevented cardiac damage associated with diabetic cardiomyopathy, including hypertrophy, fibrosis, and expression of cell death markers, at 12 weeks. However, cyclophilin D, a marker of mitochondrial permeability transition pore‐opening‐associated cell death (necrosis), was observed ...

Oxidative Stress-Responsive Apoptosis Inducing Protein (ORAIP) Plays a Critical Role in High Glucose-Induced Apoptosis in Rat Cardiac Myocytes and Murine Pancreatic β-Cells

Cells, 2017
We previously identified a novel apoptosis-inducing humoral factor in the conditioned medium of hypoxic/reoxygenated-cardiac myocytes. We named this novel post-translationally-modified secreted-form of eukaryotic translation initiation factor 5A ...

A protocol for rapid and parallel isolation of myocytes and non-myocytes from multiple mouse hearts

STAR Protocols, 2021
Summary: This protocol features parallel isolation of myocytes and non-myocytes from murine hearts. It was designed with considerations for (1) time required to extract cardiac cells, (2) cell viability, and (3) protocol scalability.

Acidosis in models of cardiac ventricular myocytes [PDF]

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2006
The effects of acidosis on cardiac electrophysiology and excitation–contraction coupling have been studied extensively. Acidosis decreases the strength of contraction and leads to altered calcium transients as a net result of complex interactions between protons and a variety of intracellular processes. The relative contributions of each of the changes

Machine Learning Models of Phase Contrast Images Predict Efficiency of Human Pluripotent Stem Cell Differentiation to Cardiomyocytes

Biotechnology and Bioengineering, EarlyView.
Human pluripotent stem cells were differentiated to cTnT+ cardiomyocytes and imaged throughout the process using phase contrast. We predicted differentiation efficiency (cTnT+ area) from phase contrast and compared model performance with a live‐cell cTnT‐GFP reporter.

A novel method of cultivating cardiac myocytes in agarose microchamber chips for studying cell synchronization

Journal of Nanobiotechnology, 2004
We have developed a new method that enables agar microstructures to be used to cultivate cardiac myocyte cells in a manner that allows their connection patterns to be controlled. Non-contact three-dimensional photo-thermal etching with a 1064-nm infrared
