Discussion

The study reveals how cardiomyocyte signaling factors affect adiposity in heart disease, highlighting GRK2's modulation role.

Cardiomyocyte secreted signaling factors influence adiposity, indicating a significant link between heart and fat.
GRK2 overexpression in cardiomyocytes reduced lipid accumulation in adipocytes and affected adipogenic markers.
Male mice with heart failure showed reduced white adipose tissue, while females exhibited no significant changes.
Findings suggest sex-specific differences in heart-to-fat communication and the role of GRK2 in adiposity.

Kereliuk et al. (2025) studied this question.
