Researchers have identified flavin-containing monooxygenase 2 (FMO2) as a critical factor in the development of myocardial hypertrophy, a condition characterized by the abnormal thickening of the heart muscle. According to the study’s findings, FMO2 plays an essential role in preserving the structure and function of mitochondrial-associated membranes (MAMs), integral components that facilitate communication and metabolic exchange between mitochondria and the endoplasmic reticulum.
The study suggests that disruptions in MAM integrity — often associated with metabolic and oxidative stress — can lead to cardiac dysfunction and contribute to heart failure. By maintaining MAM structure, FMO2 appears to counteract the pathological processes that contribute to myocardial hypertrophy.
These discoveries not only deepen scientific understanding of the cellular mechanisms underlying cardiac hypertrophy but also propose FMO2 as a potential therapeutic target. Therapies aimed at enhancing FMO2 function could represent a promising strategy for preventing or treating heart failure, a condition affecting millions worldwide.
Further research is needed to explore how FMO2 can be modulated clinically and to determine its broader implications in cardiovascular disease treatment.
