Increased mitochondrial fusion via systemic OPA1 overexpression promotes dyslipidemia and atherosclerosis in LDLR deficient mice.

ABSTRACT:

Objective

Mitochondria are involved in cellular metabolism, energy production, calcium homeostasis, and the synthesis of sterols and bile acids (BAs). Emerging evidence suggests that mitochondrial dynamics including biogenesis, fusion, fission, and mitophagy critically influence cardiometabolic diseases, yet their role in atherogenesis remain poorly understood. Mitochondrial fusion ensures metabolic flexibility and stress adaptation, processes highly relevant to lipid handling and vascular cell plasticity. OPA1, a key regulator of inner mitochondrial membrane fusion, has been implicated in metabolic remodeling and cellular stress responses. We therefore investigated whether modulation of OPA1 expression affects lipid homeostasis and plaque formation in LDL receptor-deficient (LDLR
