New clinical tools for early detection of ovarian malignancies will significantly help reduce mortality and improve current long-term survival rates. The objective of this work was to identify ovarian tumor-specific single-stranded DNA aptamers that bind to malignant ovarian tumor cells and internalize with high affinity and specificity. Aptamers can identify unique tumor biomarkers, can aid in early detection and diagnosis of neoplastic disorders, and can be functionalized by conjugation to small molecules. To identify aptamers from random single-stranded DNA pools (60 bases long), we used whole Cell-SELEX (systematic evolution of ligands by exponential enrichment) to enrich and isolate tumor-specific aptamers that bind to tumor-specific receptors in their native state on the cell surface. Next-Generation sequencing identified seven novel aptamers and detailed analyses of three are described. Aptamers bound to, and were internalized by, target Caov-3 cell populations, but not nontarget nonmalignant ovarian epithelial HOSE 6-3 cells or multiple other epithelial tumor cell lines. Furthermore, aptamers showed unique binding affinities with apparent dissociation constants (\n                    <jats:italic toggle=\"yes\">K<\/jats:italic>\n                    <jats:sub>d<\/jats:sub>\n                    ) measuring in the submicromolar range supporting their physiological relevance and potential use in clinical applications.\n                  <\/jats:p>","DOI":"10.1089\/nat.2014.0522","type":"journal-article","created":{"date-parts":[[2015,4,20]],"date-time":"2015-04-20T15:52:20Z","timestamp":1429545140000},"page":"162-172","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Identification of Epithelial Ovarian Tumor-Specific Aptamers"],"prefix":"10.1177","volume":"25","author":[{"given":"Gregory","family":"Benedetto","sequence":"first","affiliation":[{"name":"University of North Carolina Charlotte"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy J.","family":"Hamp","sequence":"additional","affiliation":[{"name":"University of North Carolina Charlotte"},{"name":"University of North Carolina Charlotte"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter J.","family":"Wesselman","sequence":"additional","affiliation":[{"name":"University of North Carolina Charlotte"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christine","family":"Richardson","sequence":"additional","affiliation":[{"name":"University of North Carolina Charlotte"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,4,20]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2008.01.033"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.2174\/138161212802002788"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/bjc.2012.207"},{"key":"e_1_3_3_5_2","doi-asserted-by":"publisher","DOI":"10.1100\/tsw.2011.112"},{"key":"e_1_3_3_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1470-2045(08)70308-5"},{"key":"e_1_3_3_7_2","doi-asserted-by":"publisher","DOI":"10.4331\/wjbc.v5.i3.286"},{"key":"e_1_3_3_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-0-387-68969-2_2"},{"key":"e_1_3_3_9_2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2105-4-24"},{"key":"e_1_3_3_10_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1471-0528.1990.tb02448.x"},{"key":"e_1_3_3_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ygyno.2008.08.031"},{"key":"e_1_3_3_12_2","doi-asserted-by":"publisher","DOI":"10.1158\/0008-5472.CAN-04-0746"},{"key":"e_1_3_3_13_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0029533"},{"key":"e_1_3_3_14_2","doi-asserted-by":"publisher","DOI":"10.1038\/mtna.2013.70"},{"key":"e_1_3_3_15_2","doi-asserted-by":"publisher","DOI":"10.7150\/thno.9663"},{"key":"e_1_3_3_16_2","first-page":"5","article-title":"Aptamers as therapeutic and diagnostic agents","volume":"74","author":"Brody EN","year":"2000","unstructured":"Brody EN, and Gold L.
