However, establishing robust disease markers is challenging due to the diversity of individual samples. New sequencing methods have simplified biomarker discovery for circulating DNA and RNA while protein profiling is still laborious and costly. To harness the power of high-throughput sequencing to profile the protein content of a biological sample, we developed a method termed APTASHAPE that uses oligonucleotide aptamers to recognize proteins in complex biofluids. We selected a large pool of 2\u2032Fluoro protected RNA sequences to recognize proteins in human plasma and identified a set of 33 cancer-specific aptamers. Differential enrichment of these aptamers after selection against 1 \u03bcl of plasma from individual patients allowed us to differentiate between healthy controls and bladder cancer-diagnosed patients (91% accuracy) and between early non-invasive tumors and late stage tumors (83% accuracy). Affinity purification and mass spectrometry of proteins bound to the predictive aptamers showed the main target proteins to be C4b-binding protein, Complement C3, Fibrinogen, Complement factor H and IgG. The APTASHAPE method thus provides a general, automated and highly sensitive platform for discovering potential new disease biomarkers.<\/jats:p>","DOI":"10.1093\/narcan\/zcac025","type":"journal-article","created":{"date-parts":[[2022,8,22]],"date-time":"2022-08-22T11:48:24Z","timestamp":1661168904000},"source":"Crossref","is-referenced-by-count":14,"title":["Differential RNA aptamer affinity profiling on plasma as a potential diagnostic tool for bladder cancer"],"prefix":"10.1093","volume":"4","author":[{"given":"S\u00f8ren","family":"Fjelstrup","sequence":"first","affiliation":[{"name":"Interdisciplinary Nanoscience Center (iNANO), Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel M","family":"Dupont","sequence":"additional","affiliation":[{"name":"Interdisciplinary Nanoscience Center (iNANO), Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claus","family":"Bus","sequence":"additional","affiliation":[{"name":"Interdisciplinary Nanoscience Center (iNANO), Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan\u00a0J","family":"Enghild","sequence":"additional","affiliation":[{"name":"Department of Molecular Biology and Genetics (MBG), Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00f8rgen\u00a0B","family":"Jensen","sequence":"additional","affiliation":[{"name":"Department of Urology, Aarhus University Hospital , Aarhus N, Denmark"},{"name":"Department of Clinical medicine, Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karin","family":"Birkenkamp-Demtr\u00f6der","sequence":"additional","affiliation":[{"name":"Department of Molecular Medicine, Aarhus University Hospital , Aarhus, Denmark"},{"name":"Department of Clinical medicine, Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lars","family":"Dyrskj\u00f8t","sequence":"additional","affiliation":[{"name":"Department of Molecular Medicine, Aarhus University Hospital , Aarhus, Denmark"},{"name":"Department of Clinical medicine, Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4128-9317","authenticated-orcid":false,"given":"J\u00f8rgen","family":"Kjems","sequence":"additional","affiliation":[{"name":"Interdisciplinary Nanoscience Center (iNANO), Aarhus University , Aarhus, Denmark"},{"name":"Department of Molecular Biology and Genetics (MBG), Aarhus University , Aarhus, Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2022,8,22]]},"reference":[{"key":"2022082211481671400_B1","doi-asserted-by":"crossref","first-page":"2357","DOI":"10.1038\/s41467-021-22444-1","article-title":"A comprehensive characterization of the cell-free transcriptome reveals tissue- and subtype-specific biomarkers for cancer detection","volume":"12","author":"Larson","year":"2021","journal-title":"Nat.
