AdipoAtlas: Mapping out human white adipose tissue

Area of Science:

• Biochemistry
• Metabolomics
• Human Physiology

Background:

• Lipidomics is crucial for understanding metabolic health.
• Human white adipose tissue (WAT) lipid profiles are complex and incompletely characterized.
• Obesity is associated with significant metabolic dysregulation.

Purpose of the Study:

• To develop AdipoAtlas, a comprehensive lipidomic resource for human WAT.
• To improve the accuracy, detection, and quantification of lipids in WAT.
• To identify specific lipid alterations associated with obesity.

Main Methods:

• Advanced mass spectrometry techniques for lipid identification and quantification.
• Development of a standardized lipidomic profiling workflow.
• Analysis of lipid profiles in human WAT samples from lean and obese individuals.

Main Results:

• AdipoAtlas provides an in-depth lipidomic profile of human WAT.
• Significantly improved accuracy and quantification of lipid species.
• Defined key obesity-mediated alterations in WAT lipid composition.

Conclusions:

• AdipoAtlas serves as a valuable resource for human WAT lipidomics.
• Obesity induces specific, quantifiable changes in WAT lipids.
• Understanding these lipid alterations may elucidate the etiology of obesity-related diseases.
