Ellis, has shown anti\u2010angiogenic potential in experimental arthritis. However, its role in metabolic regulation of angiogenesis remains unclear. The purpose was to explore the roles of GE on metabolism in angiogenesis and potential mechanisms. Adjuvant arthritis (AA) rat models and human umbilical vein endothelial cells (HUVECs) were established. Network pharmacology predicted potential targets of GE, while metabolomics analysis was conducted on RA patient serum and AA rat synovial tissue. The role of PFKFB3, a key glycolytic enzyme, was validated by gene silencing and pharmacological interventions. The signaling axis was further explored using inhibitors, agonists, and protein interaction assays. The role of the key glycolytic enzyme PFKFB3 and the upstream\u2013downstream relationship of the signaling axis were validated through gene silencing and pharmacological intervention. GE improved angiogenesis in\u00a0vivo and in\u00a0vitro models, and PFKFB3 may be a potential target. Metabolomics has shown that GE significantly inhibited the elevated levels of glycolysis metabolism in arthritis rats, which may be related to the inhibition of PFKFB3 expression. PFKFB3\u2010siRNA down\u2010regulated angiogenesis in HUVECs, demonstrating that PFKFB3\u2010mediated glycolysis was involved in angiogenesis. SphK1\u2010siRNA indicated that PFKFB3 was regulated and activated by the SphK1\u2010PI3K\u2010AKt signal and induced a high level of glycolytic metabolism phenotype. GE intervention significantly downregulated the levels of glycolysis metabolism in arthritis models by inhibiting the SphK1\u2010PI3K\u2010AKt\u2010PFKFB3 signal. The SphK1\u2010PI3K\u2010Akt\u2010PFKB3 signal is the metabolic mechanism of the natural product active ingredient GE in anti\u2010angiogenesis, revealing the important role of glycolytic metabolism in RA angiogenesis. This provides new insights into metabolic regulation in RA treatment and potential therapeutic strategies for metabolic targeted interventions.\n                  <\/jats:p>","DOI":"10.1002\/ptr.70019","type":"journal-article","created":{"date-parts":[[2025,6,30]],"date-time":"2025-06-30T04:29:16Z","timestamp":1751257756000},"page":"3419-3431","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Geniposide Improves Glycolysis Driven Angiogenesis in Experimentary Arthritis by Inhibiting\n                    <scp>SphK1<\/scp>\n                    \u2010\n                    <scp>PI3K<\/scp>\n                    \u2010Akt\u2010\n                    <scp>PFKFB3<\/scp>\n                    Signal"],"prefix":"10.1002","volume":"39","author":[{"given":"Yanhong","family":"Bu","sequence":"first","affiliation":[{"name":"Key Laboratory of Xin'an Medicine Ministry of Education  Hefei China"},{"name":"Anhui Province Key Laboratory of Chinese Medicinal Formula  Hefei China"},{"name":"Anhui Province Key Laboratory of Research &amp;
