Human Engineered Heart Tissues Reproduce Trigger‐ and Substrate‐Driven Mechanisms of Ventricular Tachycardia

Advanced Science, EarlyView.
Engineered heart tissues (EHTs) derived from human iPSCs replicate mechanisms of ventricular tachycardia at the tissue level. Acquired Long‐QT conditions cause early afterdepolarizations, wavebreak, and transient rotors; in contrast, focal cryoinjury forms a stable substrate that supports ongoing reentry.

Autosomal recessive dilated cardiomyopathy due to DOLK mutations results from abnormal dystroglycan O-mannosylation [PDF]

, 2011
Genetic causes for autosomal recessive forms of dilated cardiomyopathy (DCM) are only rarely identified, although they are thought to contribute considerably to sudden cardiac death and heart failure, especially in young children.

Melatonin Mitigates Doxorubicin‐Induced Cardiotoxicity by Targeting the USP18/PKM2 Axis Without Compromising Antitumor Efficacy

Advanced Science, EarlyView.
Melatonin engages MT1/MT2 receptors to suppress STAT1‐driven USP18 upregulation, thereby redirecting PKM2 ubiquitination from K33‐linked autophagic degradation toward K27‐linked nuclear translocation. This prevents PKM2‐mediated proinflammatory gene expression in the heart, alleviating doxorubicin‐induced cardiotoxicity without compromising antitumor ...

Endoplasmic Reticulum Stress and Diabetic Cardiomyopathy [PDF]

, 2012
The endoplasmic reticulum (ER) is an organelle entrusted with lipid synthesis, calcium homeostasis, protein folding, and maturation. Perturbation of ER-associated functions results in an evolutionarily conserved cell stress response, the unfolded protein

Stroke‐Heart Syndrome: Mechanisms, Temporal Phenotypes, and Diagnostic Reasoning

Advanced Science, EarlyView.
Stroke‐heart syndrome describes new or worsened cardiac abnormalities after acute stroke. This Review defines its clinical boundaries, traces autonomic, inflammatory, endothelial, and supply‐demand mechanisms across time, and proposes provisional phenotypes that integrate lesion location, premorbid cardiac substrate, serial biomarkers ...

Chinese Expert Consensus on the Clinical Application of Finerenone in Geriatric Comorbidities

AGING MEDICINE, EarlyView.
Mineralocorticoid receptor (MR) overactivation drives inflammation, oxidative stress, and fibrosis in the heart, kidneys, and vasculature, leading to cardiorenal dysfunction. MR signaling promotes hypertrophy, remodeling, and injury through pathways like oxidative stress and inflammation, resulting in vascular stiffness and progressive organ damage ...

COX14 Variants Are Associated With Mitochondrial Complex IV Deficiency Nuclear Type 10 (MC4DN10)

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT COX14 encodes a transmembrane protein essential for cytochrome c oxidase (COX) complex assembly. A homozygous missense variant in COX14 was reported in three siblings from a single consanguineous family with severe, fatal infantile mitochondrial complex IV deficiency nuclear type 10 (MC4DN10; MIM# 619053).
