Hub genes with positive feedbacks function as master switches in developmental gene regulatory networks

摘要

Motivation: Spatio-temporal regulation of gene expression is an indispensable characteristic in the development processes of all animals. ‘Master switches’, a central set of regulatory genes whose states (on/off or activated/deactivated) determine specific developmental fate or cell-fate specification, play a pivotal role for whole developmental processes. In this study on genome-wide integrative network analysis the underlying design principles of developmental gene regulatory networks are examined.
