Implication

Comparative laboratory study demonstrates tissue-specific extraction methods optimize lipid recovery in murine tissues, highlighting the need for tailored workflows in lipidomics.

Key Points

To systematically evaluate and identify optimal liquid-liquid extraction protocols for comprehensive, high-coverage lipidomic profiling across different tissue types.
Evaluated six liquid-liquid extraction methods (three biphasic and three monophasic) on lyophilised and fresh frozen adipose, liver, and heart tissues using liquid chromatography-mass spectrometry.
Validated the optimized protocols in an in vivo intervention study comparing C57BL/6 mice fed a high-fat diet versus a normal diet.
Optimal extraction protocols differed by tissue type: butanol:methanol (3:1) yielded 886 reproducible lipids (CV < 30%) in adipose, methyl tert-butyl ether with ammonium acetate yielded 707 lipids (CV < 30%) in liver, and butanol:methanol (1:1) yielded 311 lipids (CV < 30%) in heart.
Dietary validation uncovered significant tissue-specific metabolic shifts, identifying 374 altered lipid species across 13 subclasses in adipose tissue and 485 altered lipid species across 17 subclasses in liver tissue between diet groups.
