However, identification of cell-cycle regulated genes by raw microarray gene expression data directly is complicated by the factor of synchronization loss, thus remains a challenging problem. Decomposing the expression measurements and extracting synchronized expression will allow to better represent the single-cell behavior and improve the accuracy in identifying periodically expressed genes.<\/jats:p>\n               <jats:p>Results: In this paper, we propose a resynchronization-based algorithm for identifying cell-cycle-related genes. We introduce a synchronization loss model by modeling the gene expression measurements as a superposition of different cell populations growing at different rates. The underlying expression profile is then reconstructed through resynchronization and is further fitted to the measurements in order to identify periodically expressed genes. Results from both simulations and real mircorarray data show that the proposed scheme is promising for identifying cyclic genes and revealing underlying gene expression profiles.<\/jats:p>\n               <jats:p>Availability: Contact the authors.<\/jats:p>\n               <jats:p>Contact: \u00a0qiupeng@umd.edu<\/jats:p>\n               <jats:p>Supplementary information: Supplementary data are available at:<\/jats:p>","DOI":"10.1093\/bioinformatics\/btl017","type":"journal-article","created":{"date-parts":[[2006,1,25]],"date-time":"2006-01-25T02:48:15Z","timestamp":1138157295000},"page":"959-966","source":"Crossref","is-referenced-by-count":9,"title":["Polynomial model approach for resynchronization analysis of cell-cycle gene expression data"],"prefix":"10.1093","volume":"22","author":[{"given":"Peng","family":"Qiu","sequence":"first","affiliation":[{"name":"Department of Electrical and Computer Engineering, University of Maryland 1 \u00a0 1 \u00a0 \u00a0 College Park, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Z.
