Brief Summary: This study shows that obesity induces mitochondrial fragmentation and reduces oxidative capacity in white adipocytes through the activation of the small GTPase RalA. Targeted deletion of RalA in these cells prevents mitochondrial fragmentation, improves energy expenditure, and protects against obesity-induced metabolic dysfunctions, highlighting the critical role of RalA in obesity-related mitochondrial and metabolic abnormalities.Previous...
