Mitochondrial carrier SLC25A34 links clock, diet, and temperature control of adipocyte lipid cycling.

SLC25A34 mitochondrial transporter integrates circadian, dietary, and temperature signals to regulate adipocyte lipid metabolism, with a significant role in lipid cycling.

• Why it matters: Understanding how diverse environmental and physiological cues are coordinated at the molecular level is crucial for insights into metabolic regulation and potential obesity interventions.
• What they did: The study examined the regulation of SLC25A34 expression through circadian and environmental signals, revealing its control by REV-ERB repressors and PPARs, and proposed its role in importing oxaloacetate to support lipid synthesis.
• The result: Findings demonstrate that SLC25A34 links multiple signals to lipid metabolism, enabling adipocytes to adapt their lipid cycling in response to circadian rhythms, diet, and temperature changes.
