Towards integrative annotation of the cell-type specific gene functional and signaling map in vascular endothelial cells
Abstract
Vascular endothelial cells (VECs), which form the inner surface of blood vessels, play essential roles in many physiological and pathological processes. VECs are exposed to various micro-environmental stimuli delivered by the circulatory systems. Systematically deciphering the gene functions and signaling circuits in VECs responsive to the complex micro-environmental stimuli is one of the fundamental tasks in vascular biology. Currently, several databases aim at genome-widely annotating the gene functions and signaling circuits, but most of them take limited consideration on the cell-type specific information. And also, current annotations only provide the core genes involved in different signaling circuits, lacking the annotations on the peripheral signaling molecules or the signaling cross-talks. To quickly construct the genome-wide gene functional and signaling map in VECs, we developed a etwork-based tating system (Nanno) by integrating cell-type specific gene expression profiles, genome-wide
