Regeneration of the lizard heart after cryoinjury

Experimental Physiology, EarlyView.
Abstract Lizards are renowned for their tremendous potential to heal tissues and organs after injury, but little is known about myocardial regeneration in reptiles generally. Here, we study cardiac regeneration in the leopard gecko (Eublepharis macularius) to fill the knowledge gap between traditional models of poikilothermic (zebrafish) and ...

Mitochondrial peptide MOTS‐c suppresses systemic and cardiac inflammasome activation in a diabetic rat model

Experimental Physiology, EarlyView.
Abstract Type 2 diabetes mellitus (T2DM) is associated with chronic systemic and cardiac inflammation, contributing to the development of diabetic cardiomyopathy. The mitochondrial‐derived peptide mitochondrial open reading frame of the 12S rRNA type‐C (MOTS‐c) has emerged as a promising regulator of metabolic and inflammatory pathways.

The interplay between pulsatility, sympathetic regulation and renal physiology: Implications for left ventricular assist devices

Experimental Physiology, EarlyView.
Abstract Left ventricular assist devices have gained traction both as a bridge therapy and as a destination therapy in the management of heart failure. Many of these devices reinstate blood flow in a continuous manner as opposed to the pulsatile flow present in normal physiology.

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

The Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

In silico modelling of multi‐electrode arrays for enhancing cardiac drug testing on hiPSC‐CM heterogeneous tissues

The Journal of Physiology, EarlyView.
Abstract figure legend Schematic overview of the experimental and computational framework for investigating hiPSC‐CM electrophysiology with MEA systems. The MEA‐based model integrates experimental data with phenotype‐specific ionic models and tissue‐level heterogeneity.

Blebbistatin reduces calcium buffering in cardiomyocytes: Consequences for cellular electrophysiology

The Journal of Physiology, EarlyView.
Abstract figure legend Blebbistatin reduces Ca2+ buffering in induced pluripotent stem cell‐derived atrial cardiomyocytes. Blebbistatin, a widely used excitation–contraction uncoupling agent, decreases calcium (Ca2+) buffer affinity (increased buffer dissociation constant), leading to elevated diastolic Ca2+ levels, increased sarcoplasmic reticulum Ca2+
