We examine the involvement of hsa_circ_0000140 in DR progression and its molecular regulation. We evaluated hsa_circ_0000140 and miR\u2010485\u20105p expression in DR clinical samples and retinal endothelial cells with RT\u2010qPCR. Diagnostic utility was examined by ROC curve analysis. Dual luciferase assays validated the targeting interaction, while proliferation was characterized using CCK\u20108, migration by Transwell, and inflammatory cytokines by ELISA. Elevated levels of hsa_circ_0000140 in DR patient serum and high\u2010glucose\u2010treated hRMECs indicate its diagnostic potential. Functionally, this molecule enhances cell proliferation, migration, and inflammatory cytokine release. It directly targets miR\u2010485\u20105p, showing an inverse correlation with this microRNA. Restoring miR\u2010485\u20105p expression counteracted these pathological processes, whereas hsa_circ_0000140 overexpression suppressed miR\u2010485\u20105p function. Furthermore, miR\u2010485\u20105p directly bound OGT, a gene highly expressed in DR. Hsa_circ_0000140 shows promise as a DR diagnostic marker and contributes to disease progression through miR\u2010485\u20105p targeting, influencing retinal vascular function and inflammatory responses.<\/jats:p>","DOI":"10.1111\/apm.70212","type":"journal-article","created":{"date-parts":[[2026,5,5]],"date-time":"2026-05-05T02:51:08Z","timestamp":1777949468000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Hsa_circ_0000140 Mediates the Regulation of Retinal Microvascular Endothelial Function and Inflammation via Sponging\n                    <scp>miR<\/scp>\n                    \u2010485\u20105p in Diabetic Retinopathy"],"prefix":"10.1111","volume":"134","author":[{"given":"Ting","family":"Feng","sequence":"first","affiliation":[{"name":"Department of Ophthalmology Wuhan Puren Hospital  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ting","family":"Yan","sequence":"additional","affiliation":[{"name":"Department of Endocrinology Wuhan Jiangxia District First People's Hospital Affiliated to Hubei University of Medicine  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tanwei","family":"Wei","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology Wuhan Puren Hospital  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si","family":"Cao","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology Wuhan Puren Hospital  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-4124-6459","authenticated-orcid":false,"given":"Huan","family":"Nie","sequence":"additional","affiliation":[{"name":"Department of Urology Wuhan Puren Hospital  Wuhan Hubei China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,5,4]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.mce.2023.112042"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00125-025-06398-3"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00125-017-4435-8"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/nrdp.2016.12"},{"issue":"9","key":"e_1_2_11_6_1","first-page":"959","article-title":"Visual Function, Social Position, and Health and Life Chances","volume":"134","author":"Cumberland P.
