Matrix metalloproteinase synthesis and expression in isolated LV myocyte preparations
In several cardiac disease states, alterations in myocyte and extracellular matrix (ECM) structure occur with left ventricular (LV) remodeling and are associated with changes in matrix metalloproteinase (MMP) activity. Although nonmyocyte cell types have

Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

Intense myocyte formation from cardiac stem cells in human cardiac hypertrophy [PDF]
It is generally believed that increase in adult contractile cardiac mass can be accomplished only by hypertrophy of existing myocytes. Documentation of myocardial regeneration in acute stress has challenged this dogma and led to the proposition that ...

ABSTRACT Purpose Left ventricular (LV) strain is an early indicator of myocardial dysfunction. However, conventional strain metrics do not fully account for the multidirectional nature of myocardial deformation. The strain rate tensor, derived from velocity‐encoded MRI, represents the time‐resolved magnitude and direction of strain rate without the ...

ABSTRACT Objective Incretin‐based obesity therapies (IBTs), especially GLP‐1 receptor agonists (GLP‐1 RAs), effectively treat obesity and improve comorbidities. However, their impact on energy metabolism is unclear. A recent case of acute generalized muscle weakness in a patient with mitochondrial myopathy after tirzepatide exposure raises concerns ...

Electrical consequences of cardiac myocyte: fibroblast coupling
Gap junctions are channels which allow electrical signals to propagate through the heart from the sinoatrial node and through the atria, conduction system and onwards to the ventricles, and hence are essential for co-ordinated cardiac contraction. Twelve

Abstract The pharmaceutical industry has increasingly adopted model‐informed drug discovery and development (MID3) to enhance productivity in drug discovery and development. Quantitative systems pharmacology (QSP), which integrates drug action mechanisms and disease complexities to predict clinical endpoints and biomarkers is central to MID3.

Gentiopicroside Regulates EGFR and Induces Its Lysosomal Degradation to Attenuate Heart Failure
GPS attenuates pressure overload‐induced cardiac remodeling by promoting lysosomal degradation of EGFR. TAC‐induced EGFR accumulation activates AKT/ERK1/2 signaling and drives pathological cardiac hypertrophy, fibrosis, apoptosis, oxidative stress, and cardiac dysfunction. GPS promotes lysosome‐dependent EGFR degradation, thereby limiting excessive AKT/
