Ro5‐4864, a ligand of the mitochondrial translocator protein, protects against heart failure in mice via regulation of the p62‐Keap1‐Nrf2 axis

The Journal of Physiology, EarlyView.
Abstract figure legend Graphical abstract of the proposed Ro5‐4864 mechanism of action via p62‐Keap1‐Nrf2 axis in heart failure. TSPO, the 18‐kDa mitochondrial translocator protein of the outer mitochondrial membrane, can directly interact with p62 (also known as SQSTM1), which is crucial for the degradation of damaged mitochondria by autophagy ...

Metabolite‐sensitive cross‐bridge models of human atria reveal the impact of diabetes on muscle mechanoenergetics

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we used mathematical modelling to explore the effect of diabetes on muscle mechanoenergetics. Our parameterisation of cross‐bridge models using data from non‐diabetic and diabetic human atrial tissues revealed lower values for cross‐bridge stiffness, detachment rates, attachment rates and lower ATP sensitivity in ...

Catecholaminergic polymorphic ventricular tachycardia–linked ryanodine receptor variants exhibit domain‐specific calcium leak and calmodulin affinity properties

The Journal of Physiology, EarlyView.
Abstract figure legend Catecholaminergic polymorphic ventricular tachycardia (CPVT) variants in N terminal (NTD) and central domain (CD) but not pore domain induce a pathological RyR2 conformational shift upon protein kinase A (PKA) phosphorylation, similar to that seen in heart failure (HF), calcium/calmodulin‐dependent protein kinase II (CaMKII ...

A deep learning‐enabled toolkit for the 3D segmentation of ventricular cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend 3D cardiomyocyte segmentation enables comprehensive analyses of myocardial microstructure in health and disease; however, it is technically demanding. We present an open‐source toolkit for this task, which reduces challenges associated with sample preparation, image restoration, segmentation and proofreading.

14‐3‐3 proteins: Regulators of cardiac excitation–contraction coupling and stress responses

The Journal of Physiology, EarlyView.
Abstract figure legend 14‐3‐3 protein interactions in cardiac regulation. Schematic representation of 14‐3‐3 binding partners in excitation–contraction coupling, transcriptional regulation/development and stress response pathways. Asterisks indicate targets where the exact 14‐3‐3 binding site is unknown.
