A245: Exercise Ameliorates High-Fat Diet-Induced Cardiac Dysfunction In Drosophila By Regulating Lipin Expression, Yuepeng Li, Lan Zheng Jan 2026

A245: Exercise Ameliorates High-Fat Diet-Induced Cardiac Dysfunction In Drosophila By Regulating Lipin Expression, Yuepeng Li, Lan Zheng

International Journal of Physical Activity and Health

High-fat diet (HFD) induces systemic lipid metabolism disorders and cardiac dysfunction, including arrhythmias, decreased cardiac contractility, and other pathological phenotypes. Exercise as a non-pharmacological intervention has potential protective effects against metabolic diseases, but its molecular mechanisms have not been fully elucidated. Lipin genes play a pivotal role in metabolic homeostasis by integrating lipid synthesis, catabolism, and energy-sensing signals. In this study, we used Drosophila as a model to investigate whether exercise ameliorates HFD-induced cardiac dysfunction in Drosophila by regulating the expression of Lipin, a key gene for lipid metabolism. Method: Wild-type female Drosophila (n=360) within 12 hours of pinning were …
