Žitnik, Marinka A. Nam, Edward Dinh, Christopher Kuspa, Adam Shaulsky, Gad Zupan, Blaž Gene Prioritization by Compressive Data Fusion and Chaining <div><p>Data integration procedures combine heterogeneous data sets into predictive models, but they are limited to data explicitly related to the target object type, such as genes. Collage is a new data fusion approach to gene prioritization. It considers data sets of various association levels with the prediction task, utilizes collective matrix factorization to compress the data, and chaining to relate different object types contained in a data compendium. Collage prioritizes genes based on their similarity to several seed genes. We tested Collage by prioritizing bacterial response genes in <i>Dictyostelium</i> as a novel model system for prokaryote-eukaryote interactions. Using 4 seed genes and 14 data sets, only one of which was directly related to the bacterial response, Collage proposed 8 candidate genes that were readily validated as necessary for the response of <i>Dictyostelium</i> to Gram-negative bacteria. These findings establish Collage as a method for inferring biological knowledge from the integration of heterogeneous and coarsely related data sets.</p></div> Collage prioritizes genes;14 data sets;data sets;response;8 candidate genes;novel model system;Chaining Data integration procedures;data fusion approach;4 seed genes;target object type;Compressive Data Fusion 2015-10-14
