Inferring Gene Regulatory Network Architecture Underlying Complex Traits: An Integrative Analysis of Mutant Lifespan and Gene Expression Profiles Identifies Master Regulators and Key Functional Modules for Yeast Aging.

Abstract excerpt

Complex phenotypes, including aging, are influenced by a connected gene regulatory network with many interacting nodes. It has been proposed that some genes, termed "core genes," directly contribute to a trait, whereas "peripheral genes" influence the trait indirectly through network interactions. Yet demonstrating such a layered architecture and assigning genes to layers remains challenging. Using yeast aging,...
