Circulating microRNAs are much more stable than mRNAs and remain largely intact even after prolonged incubation at room temperature. However, recent reports show that microRNAs in serum or plasma samples have diverse stabilities. The aim of this pilot study is to evaluate the stabilities of miR-92a, miR-122 and miR-145 in serum during transient storage at 4\u2103 before freezing.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Serum samples were stored for 24\u2009h at 4\u2103, and then RNA was extracted from whole serum or extracellular vesicles in serum. Total Exosome Isolation Reagent (from serum) was used for the fractionation of extracellular vesicles. Reverse transcription and real-time PCR of microRNAs were performed using the TaqMan MicroRNA Assays for miR-92a, miR-122 and miR-145.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n MiR-122 and miR-145 were degraded rapidly in serum; the concentrations dropped to 35.9% ( P\u2009<\u20090.001) and 29.3% ( P\u2009<\u20090.0001), respectively. These microRNAs in extracellular vesicles exhibited similar instability; the concentrations were 52.2% ( P\u2009<\u20090.05) and 56.5% ( P\u2009<\u20090.01), respectively. On the other hand, no significant degradation of miR-92a was observed (whole serum: P\u2009=\u20090.052, extracellular vesicles: P\u2009=\u20090.196).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n MiR-122 and miR-145 in serum are extremely unstable and could be degraded during transient storage of serum at 4\u2103 prior to freezing.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/0004563217704233","type":"journal-article","created":{"date-parts":[[2017,4,4]],"date-time":"2017-04-04T01:23:49Z","timestamp":1491269029000},"page":"178-180","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":13,"title":["Degradation of serum microRNAs during transient storage of serum samples at 4\u2103"],"prefix":"10.1177","volume":"55","author":[{"given":"Toshiko","family":"Aiso","sequence":"first","affiliation":[{"name":"Department of Medical Technology, Faculty of Health Sciences, Kyorin University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shu","family":"Takigami","sequence":"additional","affiliation":[{"name":"Department of Medical Technology, Faculty of Health Sciences, Kyorin University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akiko","family":"Yamaki","sequence":"additional","affiliation":[{"name":"Department of Medical Technology, Faculty of Health Sciences, Kyorin University, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroaki","family":"Ohnishi","sequence":"additional","affiliation":[{"name":"Department of Laboratory Medicine, Kyorin University School of Medicine, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,6,29]]},"reference":[{"key":"bibr1-0004563217704233","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0804549105"},{"key":"bibr2-0004563217704233","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0075184"},{"key":"bibr3-0004563217704233","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0112481"},{"key":"bibr4-0004563217704233","first-page":"688","volume":"63","author":"Aiso T","year":"2015","journal-title":"Rinsho Byori"},{"key":"bibr5-0004563217704233","doi-asserted-by":"publisher","DOI":"10.1002\/cncr.27895"},{"key":"bibr6-0004563217704233","doi-asserted-by":"publisher","DOI":"10.1373\/clinchem.2014.221341"}],"container-title":["Annals of Clinical Biochemistry: International Journal of Laboratory Medicine"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0004563217704233","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0004563217704233","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0004563217704233","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T12:23:13Z","timestamp":1777378993000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0004563217704233"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,6,29]]},"references-count":6,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2018,1]]}},"alternative-id":["10.1177\/0004563217704233"],"URL":"https:\/\/doi.org\/10.1177\/0004563217704233","relation":{},"ISSN":["0004-5632","1758-1001"],"issn-type":[{"value":"0004-5632","type":"print"},{"value":"1758-1001","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,6,29]]}}}
