This disease also imposes a heavy economic burden on both patients and public health agencies due to high medical costs. Current common therapies, such as surgical intervention, chemical treatment, and radiotherapy, are associated with serious adverse reactions and risks of metastasis recurrence. Effective attenuation of bladder cancer proliferation and invasion remains a significant challenge. Circular RNAs have shown promise in regulating proliferation and migration of cancer cells, thus making it a potential therapeutic target for bladder cancer treatment and prognosis. This study aims to evaluate the impact of regulating circPTK2 expression on progression of bladder cancer. Methods: This research established overexpression and knock down circPTK2 models of bladder cancer cells (SW780 and UM-UC-3) primarily. Then evaluate the effect by a series of cell function test (including RT-qPCR, MTT, EdU assay, cell clone, transwell, cell cycle and cell apoptosis). Results: The findings suggest that regulated expression of circPTK2 in bladder cancer cells correlated with the abundance of mir129-5p. Meanwhile, knock down circPTK2 expression in bladder cancer cells reduced their ability to proliferate and invade; but these processes were reversed when circPTK2 expression was increased. Conclusion: In conclusion, circPTK2 may play a vital role in regulating bladder cancer progression, thereby showing potential for treatment of bladder cancer and improvement of prognosis by modulating circPTK2.<\/jats:p>","DOI":"10.33594\/000000792","type":"journal-article","created":{"date-parts":[[2025,7,14]],"date-time":"2025-07-14T07:59:11Z","timestamp":1752479951000},"page":"453-464","source":"Crossref","is-referenced-by-count":0,"title":["Protein Tyrosine Kinase 2 Circular RNA Promotes Proliferation and Invasion of Bladder Cancer"],"prefix":"10.33594","volume":"59","author":[{"given":"Jingyi","family":"Cao","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangyue","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yan","family":"Zhao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guihua","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qian","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hua","family":"Peng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Liang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Zhou","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuning","family":"Dong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shasha","family":"Li","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ke","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changsong","family":"Pei","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qichao","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"19235","published-online":{"date-parts":[[2025,7,14]]},"container-title":["Cellular Physiology and Biochemistry"],"original-title":[],"deposited":{"date-parts":[[2025,7,14]],"date-time":"2025-07-14T07:59:12Z","timestamp":1752479952000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cellphysiolbiochem.com\/Articles\/000792\/index.html"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,7,14]]},"references-count":0,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2025,7,14]]}},"URL":"https:\/\/doi.org\/10.33594\/000000792","relation":{},"ISSN":["1015-8987","1421-9778"],"issn-type":[{"type":"print","value":"1015-8987"},{"type":"electronic","value":"1421-9778"}],"subject":[],"published":{"date-parts":[[2025,7,14]]}}}
