Barth syndrome (BTHS) is a rare X-linked recessively inherited disorder caused by variants in the TAFAZZIN gene. The pathogenic variants lead to impaired conversion of monolysocardiolipin (MLCL) into mature phospholipid cardiolipin (CL). The accumulation of MLCL and mature CL deficiency is a diag...
Functional stem cell-derived heart models offer new avenues for preclinical, animal-free physiological assessment of drug cardiotoxicity. Yet, comprehensive molecular profiling in these models remains limited, leaving key metabolic drivers of cardiotoxicity unexplored.
Here, we leveraged an...
Background: Heart failure with reduced ejection fraction (HFrEF) is characterized by impaired contractility and high mortality. Dysregulation of intracellular ion cycling underlies the decline in cardiac contractility. Modulation of cardiac Na+/H+ and Ca2+ handling is consider...
Exercise promotes physiological cardiomyocyte growth and protects against ischemia/reperfusion (I/R) injury in the heart. The molecular mechanism by which exercise benefits cardiac metabolism and function remains largely unknown. Exercise (swimming or treadmill)-induced physiological hypertrophy ...
