Adipose–hypothalamus coexpression subnetworks, including circadian genes, associate with obesity-related biology beyond single-tissue views.

Key findings

Several adipose–hypothalamus TTC subnetworks map to biological functions; a central C2 subnetwork is enriched for obesity- and circadian-related genes (e.g., Arntl, Per1/2).

Methodology

Built multi-tissue coexpression networks integrating expression across tissues to find cross-tissue subnetworks linked to disease traits.

Limitations

Network enrichment is not a clinical treatment trial; causality of each edge remains to be tested.
