The fluorescence intensity corresponding to the protected RNA fragment increased in a dose-dependent manner with respect to the complementary-strand RNA. More highly sensitive detection of miRNA by microchip electrophoresis than by conventional method using fluorescence-labeled riboprobe could be obtained in 180 s. An obvious increase in miR-222 expression induced by nerve growth factor in PC12 cells could be observed. These results clearly indicate the potential of microchip electrophoresis for the analysis of miRNA using RNase protection assay with a fluorescence-labeled riboprobe.<\/jats:p>","DOI":"10.3390\/s120607576","type":"journal-article","created":{"date-parts":[[2012,6,7]],"date-time":"2012-06-07T11:01:10Z","timestamp":1339066870000},"page":"7576-7586","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["Detection of miRNA in Cell Cultures by Using Microchip Electrophoresis with a Fluorescence-Labeled Riboprobe"],"prefix":"10.3390","volume":"12","author":[{"given":"Shohei","family":"Yamamura","sequence":"first","affiliation":[{"name":"Health Research Institute, National Institute of Advanced Industrial Science and Technology (AIST), 2217-14 Hayashi-cho, Takamatsu, Kagawa 761-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shouki","family":"Yatsushiro","sequence":"additional","affiliation":[{"name":"Health Research Institute, National Institute of Advanced Industrial Science and Technology (AIST), 2217-14 Hayashi-cho, Takamatsu, Kagawa 761-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuka","family":"Yamaguchi","sequence":"additional","affiliation":[{"name":"Health Research Institute, National Institute of Advanced Industrial Science and Technology (AIST), 2217-14 Hayashi-cho, Takamatsu, Kagawa 761-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaori","family":"Abe","sequence":"additional","affiliation":[{"name":"Health Research Institute, National Institute of Advanced Industrial Science and Technology (AIST), 2217-14 Hayashi-cho, Takamatsu, Kagawa 761-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuo","family":"Shinohara","sequence":"additional","affiliation":[{"name":"Division of Protein Expression, Institute for Genome Research, University of Tokushima, Kuramoto 3-18-15, Tokushima 770-8503, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Masatoshi","family":"Kataoka","sequence":"additional","affiliation":[{"name":"Health Research Institute, National Institute of Advanced Industrial Science and Technology (AIST), 2217-14 Hayashi-cho, Takamatsu, Kagawa 761-0395, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2012,6,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e6229","DOI":"10.1371\/journal.pone.0006229","article-title":"Detection of cancer with serum miRNAs on an oligonucleotide microarray","volume":"4","author":"Lodes","year":"2009","journal-title":"PLoS One"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1268","DOI":"10.1261\/rna.2069310","article-title":"Use of two novel approaches to discriminate between closely related host microRNAs that are manipulated by Toxoplasma gondii during infection","volume":"16","author":"Zeiner","year":"2010","journal-title":"RNA"},{"key":"ref_3","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":"ref_4","doi-asserted-by":"crossref","first-page":"857","DOI":"10.1038\/nrc1997","article-title":"MicroRNA signatures in human cancers","volume":"6","author":"Calin","year":"2006","journal-title":"Nat.
