Previous studies have shown that circular RNA and ferroptosis play significant roles in various cardiovascular diseases, regulating disease progression. However, there is little research on how circular RNA regulates ferroptosis in vascular smooth muscle cells during AD progression, and the specific molecular mechanisms remain a mystery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec xml:lang=\"en\">\n                    <jats:title>Methods and Results<\/jats:title>\n                    <jats:p xml:lang=\"en\">In this study, we found that circTMEM71 is downregulated in AD and angiotensin II\u2013induced human aortic smooth muscle cells and inhibits ferroptosis. Mechanistically, circTMEM71 can bind to IGF2BP3 (insulin\u2010like growth factor II mRNA\u2010binding protein 3) and inhibit its degradation via the ubiquitin\u2010mediated proteasome pathway. Additionally, IGF2BP3 can bind to FSP1 (ferroptosis suppressor protein 1) mRNA, enhancing its stability and thus suppressing cellular ferroptosis. Finally, we also confirmed that circTMEM71 can alleviate symptoms of AD in Sprague\u2013Dawley rats through in\u00a0vivo experiments, including histopathologic changes and ferroptosis.<\/jats:p>\n

suggested that circTMEM71 is a potential therapeutic target for AD and highlights its role in inhibiting ferroptosis in vascular smooth muscle cells.<\/jats:p>\n
