In silico characterization of these molecules revealed that all of them exhibited at least 1 feature commonly associated with RNAs possessing regulatory functions, such as coding truncated protein isoform, exosomal localization, or enrichment in repetitive elements. The most prominently dysregulated transcripts with consistent expression profiles across both datasets were NTMT1-204 (up-regulated in cancer) and BLOC1S6-218 and DCTN1-205 (both down-regulated in cancer). The remaining 343 transcripts did not show consistent expression patterns in the cell lines, suggesting their dysregulation in patient-derived tissues may be due to the stromal or microenvironmental factors absent in vitro.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>In summary, this comparative transcriptomic analysis identified 32 transcript isoforms, comprising 2 canonical and 30 non-canonical transcripts, that may play regulatory roles in colon carcinogenesis and warrant further investigation in the context of gut epithelial cell biology.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/11769351251396250","type":"journal-article","created":{"date-parts":[[2025,11,25]],"date-time":"2025-11-25T05:36:21Z","timestamp":1764048981000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Comparative RNA-Seq Analysis of Colon Spheroids and Patient-derived Tissues Identifies Non-Canonical Transcript Isoforms of Protein-Coding Genes Implicated in Colon Carcinogenesis"],"prefix":"10.1177","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7117-7944","authenticated-orcid":false,"given":"Tamara","family":"Babic","sequence":"first","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bojana","family":"Banovic Djeri","sequence":"additional","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dunja","family":"Pavlovic","sequence":"additional","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Dragicevic","sequence":"additional","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jovana","family":"Despotovic","sequence":"additional","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jelena","family":"Karanovic","sequence":"additional","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aleksandra","family":"Nikolic","sequence":"additional","affiliation":[{"name":"Group for gene Regulation in Cancer, Institute of Molecular Genetics and Genetic Engineering, University of Belgrade, Belgrade, Serbia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,11,24]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21763"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJMra0804588"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2016.12.013"},{"issue":"6","key":"e_1_3_3_5_2","article-title":"A pan-cancer transcriptome analysis reveals pervasive regulation through alternative promoters","volume":"178","author":"Demircio\u011flu D","year":"2019","unstructured":"Demircio\u011flu D, Cukuroglu E, Kindermans M, et al.
