However, one major issue in miRNA studies is the lack of bioinformatics programs to accurately predict miRNA targets. Animal miRNAs have limited sequence complementarity to their gene targets, which makes it challenging to build target prediction models with high specificity.<\/jats:p>\n               <jats:p>Results: Here we present a new miRNA target prediction program based on support vector machines (SVMs) and a large microarray training dataset. By systematically analyzing public microarray data, we have identified statistically significant features that are important to target downregulation. Heterogeneous prediction features have been non-linearly integrated in an SVM machine learning framework for the training of our target prediction model, MirTarget2. About half of the predicted miRNA target sites in human are not conserved in other organisms. Our prediction algorithm has been validated with independent experimental data for its improved performance on predicting a large number of miRNA down-regulated gene targets.<\/jats:p>\n               <jats:p>Availability: All the predicted targets were imported into an online database miRDB, which is freely accessible at http:\/\/mirdb.org.<\/jats:p>\n               <jats:p>Contact: \u00a0xwang@radonc.wustl.edu<\/jats:p>\n               <jats:p>Supplementary information: Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btm595","type":"journal-article","created":{"date-parts":[[2007,11,30]],"date-time":"2007-11-30T01:29:20Z","timestamp":1196386160000},"page":"325-332","source":"Crossref","is-referenced-by-count":418,"title":["Prediction of both conserved and nonconserved microRNA targets in animals"],"prefix":"10.1093","volume":"24","author":[{"given":"Xiaowei","family":"Wang","sequence":"first","affiliation":[{"name":"Department of Radiation Oncology, Washington University School of Medicine, St. Louis, MO 63110, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Issam M.","family":"El Naqa","sequence":"additional","affiliation":[{"name":"Department of Radiation Oncology, Washington University School of Medicine, St. Louis, MO 63110, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2007,11,29]]},"reference":[{"key":"2023061011433998100_B1","doi-asserted-by":"crossref","first-page":"350","DOI":"10.1038\/nature02871","article-title":"The functions of animal microRNAs","volume":"431","author":"Ambros","year":"2004","journal-title":"Nature"},{"key":"2023061011433998100_B2","doi-asserted-by":"crossref","first-page":"553","DOI":"10.1016\/j.cell.2005.07.031","article-title":"Regulation by let-7 and lin-4 miRNAs results in target mRNA degradation","volume":"122","author":"Bagga","year":"2005","journal-title":"Cell"},{"key":"2023061011433998100_B3","doi-asserted-by":"crossref","first-page":"D760","DOI":"10.1093\/nar\/gkl887","article-title":"NCBI GEO: mining tens of millions of expression profiles\u2014database and tools update","volume":"35","author":"Barrett","year":"2007","journal-title":"Nucleic Acids Res"},{"key":"2023061011433998100_B4","doi-asserted-by":"crossref","first-page":"D21","DOI":"10.1093\/nar\/gkl986","article-title":"GenBank","volume":"35","author":"Benson","year":"2007","journal-title":"Nucleic Acids Res"},{"key":"2023061011433998100_B5","doi-asserted-by":"crossref","first-page":"e85","DOI":"10.1371\/journal.pbio.0030085","article-title":"Principles of microRNA-target recognition","volume":"3","author":"Brennecke","year":"2005","journal-title":"PLoS Biol"},{"key":"2023061011433998100_B6","doi-asserted-by":"crossref","first-page":"1552","DOI":"10.1109\/TMI.2002.806569","article-title":"A support vector machine approach for detection of microcalcifications","volume":"21","author":"El-Naqa","year":"2002","journal-title":"IEEE Trans.
