Mitochondrial Control of Glycerolipid Synthesis by a PEP Shuttle
Recent research published in the journal Cell identifies SLC25A35 as the critical mitochondrial exporter of phosphoenolpyruvate (PEP), establishing a direct link between mitochondrial energetics and lipid production in lipogenic cells. This discovery reveals that mitochondrial PEP flux is essential for driving the synthesis of glycerol-3-phosphate and triglycerides, which are fundamental components of cellular fats. The study demonstrates that blocking the activity of SLC25A35 significantly reduces hepatic steatosis, a condition characterized by excessive fat accumulation in the liver. These findings provide new insights into the metabolic pathways governing lipid synthesis and highlight SLC25A35 as a promising therapeutic target for treating metabolic disorders associated with fatty liver disease. By elucidating the mechanism through which mitochondria license glycerolipid synthesis, this research opens potential avenues for developing novel interventions to manage obesity-related metabolic conditions and improve liver health.
