As a method of choice, differential equations are used for this purpose, because they provide a detailed insight into the dynamic behavior of the system. In most cases, the number of time points of experimental time series is usually too small to estimate the parameters of a model of a whole gene regulatory network based on differential equations, such that one needs to focus on subnetworks consisting of only a few components. For most approaches, the set of components of the subsystem is given in advance and only the structure has to be estimated. However, the set of components that influence the system significantly are not always known in advance, making a method desirable that determines both, the components that are included into the model and the parameters.<\/jats:p>\n               <jats:p>Results: We have developed a method that uses gene expression data as well as interaction data between cell components to define a set of genes that we use for our modeling. In a subsequent step, we estimate the parameters of our model of piecewise linear differential equations and evaluate the results simulating the behavior of the system with our model.<\/jats:p>\n               <jats:p>We have applied our method to the DNA repair system of Mycobacterium tuberculosis. Our analysis predicts that the gene Rv2719c plays an important role in this system.<\/jats:p>\n               <jats:p>Contact: \u00a0{radde.gebert}@zpr.uni-koeln.de, chris@lanl.gov<\/jats:p>","DOI":"10.1093\/bioinformatics\/btl440","type":"journal-article","created":{"date-parts":[[2006,8,23]],"date-time":"2006-08-23T03:33:41Z","timestamp":1156304021000},"page":"2674-2680","source":"Crossref","is-referenced-by-count":10,"title":["Systematic component selection for gene-network refinement"],"prefix":"10.1093","volume":"22","author":[{"given":"Nicole","family":"Radde","sequence":"first","affiliation":[{"name":"Center for Applied Computer Science, University of Cologne 1 \u00a0 1 \u00a0 \u00a0 Weyertal 80, 50931 Cologne, Germany"}]},{"given":"Jutta","family":"Gebert","sequence":"additional","affiliation":[{"name":"Center for Applied Computer Science, University of Cologne 1 \u00a0 1 \u00a0 \u00a0 Weyertal 80, 50931 Cologne, Germany"}]},{"given":"Christian V.","family":"Forst","sequence":"additional","affiliation":[{"name":"Los Alamos National Laboratory 2 \u00a0 2 \u00a0 \u00a0 PO Box 1663, Mailstop M888, Los Alamos, NM 87545, USA"}]}],"member":"286","published-online":{"date-parts":[[2006,8,22]]},"reference":[{"key":"2023012408424634200_b1","doi-asserted-by":"crossref","first-page":"815","DOI":"10.1093\/bioinformatics\/btl003","article-title":"Inference of gene regulatory networks and compound mode of action from time course gene expression profiles","volume":"22","author":"Bansal","year":"2006","journal-title":"Bioinformatics"},{"key":"2023012408424634200_b2","doi-asserted-by":"crossref","first-page":"40174","DOI":"10.1074\/jbc.M406796200","article-title":"The transcriptional response of Mycobacterium tuberculosis to inhbitors of metabolism: novel insights into drug mechanisms of action","volume":"279","author":"Boshoff","year":"2004","journal-title":"Biol.
