Abstract
AbstractCongenital heart disease (CHD) represents a major birth defect associated with substantial morbidity and mortality. Although environmental factors are acknowledged as potential contributors to CHD, the underlying mechanisms remain poorly understood. Bisphenol A (BPA), a common endocrine disruptor, has attracted significant attention due to its widespread use and associated health risks. This study examined the effects of maternal BPA exposure on fetal heart development in a murine model. The findings indicated that high‐dose BPA exposure resulted in fetal growth restriction, myocardial wall thinning, and ventricular septal defects. Transcriptomic analysis revealed downregulation of genes associated with mitochondrial energy synthesis and cardiomyocyte development following high‐dose BPA exposure. Functional assays demonstrated that high‐dose BPA exposure impaired mitochondrial respiration reduced ATP production, disrupted mitochondrial membrane potential, and increased intracellular reactive oxygen species levels in fetal cardiomyocytes. These results elucidate the detrimental effects of BPA on fetal heart development and mitochondrial function, providing insights into potential mechanisms linking environmental chemical exposure to CHD.
