Fig. 3From: From comorbidities of chronic obstructive pulmonary disease to identification of shared molecular mechanisms by data integrationFramework to uncover co-morbidity associated mechanisms. The figure depicts first the use of gene-disease associations from multiple disease ontologies/nomenclatures and multiple disease-gene databases (and mappings from UMLS) to generate mapping1 (red block: 1) and its extension through PPI associations to generate mapping2 (red block: 2). Secondly, the figure depicts the computation of Disease Groups (red block: 3). Finally, the figure depicts the mapping of gene-DGs that results in mapping1_DG and mapping2_DG (red block: 4) and their pathway extensions (red block: 5)Back to article page
