endophenotypic module

Different diseases often have common underlying mechanisms and shared intermediate pathophenotypes, or endophenotypes.

Within this framework, a specific disease’s expression is a consequence of the interplay between the relevant endophenotypes and their local, organ-based environment. Important examples of such endophenotypes are inflammation, fibrosis, and thrombosis and their essential roles in many developing diseases.

In a study, it has been constructed endophenotype network models and explore their relation to different diseases in general and to cardiovascular diseases in particular.

The authors identify the local neighborhoods (module) within the interconnected map of molecular components, i.e., the subnetworks of the human interactome that represent the inflammasome, thrombosome, and fibrosome.

They find that these neighborhoods are highly overlapping and significantly enriched with disease-associated genes. In particular they are also enriched with differentially expressed genes linked to cardiovascular disease (risk).

Finally, using proteomic data, they explore how macrophage activation contributes to our understanding of inflammatory processes and responses. The results of their analysis show that inflammatory responses initiate from within the cross-talk of the three identified endophenotypic modules.
