As miRNA expression is highly cell specific, an automatic and systematic method that could identify miRNA TSSs accurately and cell specifically is in urgent requirement.<\/jats:p>\n               <jats:p>Results: A workflow to identify the TSSs of miRNAs was built by integrating the data of H3K4me3 and DNase I hypersensitive sites as well as combining the conservation level and sequence feature. By applying the workflow to the data for 54 cell lines from the ENCODE project, we successfully identified TSSs for 663 intragenic miRNAs and 620 intergenic miRNAs, which cover 84.2% (1283\/1523) of all miRNAs recorded in miRBase 18. For these cell lines, we found 4042 alternative TSSs for intragenic miRNAs and 3186 alternative TSSs for intergenic miRNAs. Our method achieved a better performance than the previous non-cell-specific methods on miRNA TSSs. The cell-specific method developed by Georgakilas et al. gives 158 TSSs of higher accuracy in two cell lines, benefitting from the employment of deep-sequencing technique. In contrast, our method provided a much higher number of miRNA TSSs (7228) for a broader range of cell lines without the limitation of costly deep-sequencing data, thus being more applicable for various experimental cases. Analysis showed that upstream promoters at\u2009\u2212\u20092\u2009kb to\u2009\u2212\u2009200\u2009bp of TSS are more conserved for independently transcribed miRNAs, while for miRNAs transcribed with host genes, their core promoters (\u2212200\u2009bp to 200\u2009bp of TSS) are significantly conserved.<\/jats:p>\n               <jats:p>Availability and implementation: Predicted miRNA TSSs and promoters can be downloaded from supplementary files.<\/jats:p>\n               <jats:p>Contact: \u00a0jwang@nju.edu.cn or jlee@nju.edu.cn or edgar.wingender@bioinf.med.uni-goettingen.de<\/jats:p>\n               <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btw171","type":"journal-article","created":{"date-parts":[[2016,4,20]],"date-time":"2016-04-20T01:30:19Z","timestamp":1461115819000},"page":"2403-2410","source":"Crossref","is-referenced-by-count":18,"title":["Identifying cell-specific microRNA transcriptional start sites"],"prefix":"10.1093","volume":"32","author":[{"given":"Xu","family":"Hua","sequence":"first","affiliation":[{"name":"1 The State Key Laboratory of Pharmaceutical Biotechnology and Jiangsu Engineering Research Center for MicroRNA Biology and Biotechnology, NJU Advanced Institute for Life Sciences (NAILS), School of Life Science, Nanjing University, Nanjing 210093, China"},{"name":"2 Department of Bioinformatics, Medical School, George August University of G\u00f6ttingen, Goldschmidtstrasse 1, G\u00f6ttingen D-37077, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luxiao","family":"Chen","sequence":"additional","affiliation":[{"name":"1 The State Key Laboratory of Pharmaceutical Biotechnology and Jiangsu Engineering Research Center for MicroRNA Biology and Biotechnology, NJU Advanced Institute for Life Sciences (NAILS), School of Life Science, Nanjing University, Nanjing 210093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Wang","sequence":"additional","affiliation":[{"name":"1 The State Key Laboratory of Pharmaceutical Biotechnology and Jiangsu Engineering Research Center for MicroRNA Biology and Biotechnology, NJU Advanced Institute for Life Sciences (NAILS), School of Life Science, Nanjing University, Nanjing 210093, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Li","sequence":"additional","affiliation":[{"name":"1 The State Key Laboratory of Pharmaceutical Biotechnology and Jiangsu Engineering Research Center for MicroRNA Biology and Biotechnology, NJU Advanced Institute for Life Sciences (NAILS), School of Life Science, Nanjing University, Nanjing 210093, China"},{"name":"2 Department of Bioinformatics, Medical School, George August University of G\u00f6ttingen, Goldschmidtstrasse 1, G\u00f6ttingen D-37077, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edgar","family":"Wingender","sequence":"additional","affiliation":[{"name":"2 Department of Bioinformatics, Medical School, George August University of G\u00f6ttingen, Goldschmidtstrasse 1, G\u00f6ttingen D-37077, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2016,4,19]]},"reference":[{"key":"2023020112524466800_btw171-B1","doi-asserted-by":"crossref","first-page":"D36","DOI":"10.1093\/nar\/gks1195","article-title":"GenBank","volume":"41","author":"Benson","year":"2013","journal-title":"Nucleic Acids Res"},{"key":"2023020112524466800_btw171-B2","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1038\/nature11247","article-title":"An integrated encyclopedia of DNA elements in the human genome","volume":"489","author":"Bernstein","year":"2012","journal-title":"Nature"},{"key":"2023020112524466800_btw171-B3","doi-asserted-by":"crossref","first-page":"R90","DOI":"10.1186\/gb-2010-11-8-r90","article-title":"Comprehensive modeling of microRNA targets predicts functional non-conserved and non-canonical sites","volume":"11","author":"Betel","year":"2010","journal-title":"Genome Biol"},{"key":"2023020112524466800_btw171-B4","doi-asserted-by":"crossref","first-page":"310","DOI":"10.1016\/j.gpb.2012.08.005","article-title":"miRT: a database of validated transcription start sites of human microRNAs","volume":"10","author":"Bhattacharyya","year":"2012","journal-title":"Genomics Proteomics Bioinformatics"},{"key":"2023020112524466800_btw171-B5","doi-asserted-by":"crossref","first-page":"1097","DOI":"10.1038\/nsmb1167","article-title":"RNA polymerase III transcribes human microRNAs","volume":"13","author":"Borchert","year":"2006","journal-title":"Nat.
