FGF21/sirtuin 1 axis mediates the cardioprotective effects of high‐intensity interval training against doxorubicin‐induced cardiotoxicity by reducing inflammatory and oxidative stress

open access: yesExperimental Physiology, EarlyView.
Abstract Doxorubicin (DOX) is a potent anthracycline chemotherapeutic agent, but its clinical use is limited by cumulative cardiotoxicity. Exercise, particularly high‐intensity interval training (HIIT), has emerged as an effective non‐pharmacological strategy to counteract chemotherapy‐induced cardiac injury.

Fenofibrate plus Metformin Produces Cardioprotection in a Type 2 Diabetes and Acute Myocardial Infarction Model

open access: yesPPAR Research, 2016
We investigated whether fenofibrate, metformin, and their combination generate cardioprotection in a rat model of type 2 diabetes (T2D) and acute myocardial infarction (AMI). Streptozotocin-induced diabetic- (DB-) rats received 14 days of either vehicle,

Prediabetic cardiomyopathy is attenuated by hypothalamic PVN oxytocin neuron activation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend A long‐term high‐fat, high‐fructose diet induces prediabetes with insulin resistance, hyperinsulinaemia, elevated triglycerides and metabolic‐associated steatotic liver disease (MASLD) in male rats. Animals developed prediabetic cardiomyopathy characterized by diastolic dysfunction, interstitial fibrosis and tachycardia ...

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

open access: yesThe 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 ...

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Insights from animal models: Dissecting the independent roles of oxygen and nutrients in the fetal origins of cardiovascular disease

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend This review utilized animal models of complicated human pregnancies that result in reduced fetal nutrient or oxygen delivery, or combined nutrient and oxygen delivery, to elucidate their independent and/or synergistic contributions to the development of high‐risk cardiac phenotypes.

Circular RNAs: Unlocking new avenues in cardiometabolic disease management

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend In the heart circular RNAs (circRNAs) function as microRNA sponges, interact with proteins and can even undergo translation. Advances in bioinformatics now enable their identification through high‐throughput RNA sequencing, whereas computational analyses reveal differential expression in cardiac disease settings.

Molecular Mechanisms in Exercise-Induced Cardioprotection

open access: yesCardiology Research and Practice, 2011
Physical inactivity is increasingly recognized as modifiable behavioral risk factor for cardiovascular diseases. A partial list of proposed mechanisms for exercise-induced cardioprotection include induction of heat shock proteins, increase in cardiac ...

When NCX switches sides: Experimental and computational insights into Ca2+ regulation in the heart

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Due to its presence inside the dyadic cleft, Na+/Ca2+ exchanger (NCX) builds a functional unit together with L‐type calcium channels and ryanodine receptors in the dyadic cleft. NCX acts bidirectionally (forward and reverse mode) dependent on extracellular calcium ([Ca2+]o) and sodium ([Na+]o) concentrations and the membrane ...

Age‐ and sex‐specific modulation of human cardiac electrophysiology by doxorubicin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend DOX differentially impacts cardiac electrophysiology based on sex and age. Sex differences were primarily observed among younger hearts, where action potential duration (APD) prolongation was observed in females, but not in males. Created using BioRender. George, S. (2026) https://BioRender.com/wresf1k Abstract Acute doxorubicin (
