This study aimed to investigate the effects of IPA on mesenteric vascular endothelial function and blood pressure in high\u2010fat diet\u2010induced obese (DIO) mice.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>C57BL\/6 mice were fed a high\u2010fat diet for 3\u2009months to induce the DIO model. DIO mice were gavaged daily with IPA (20\u2009mg\/kg) for 6\u2009weeks. At the end of the treatment, inflammatory markers and nitric oxide (NO) levels in primary mesenteric artery endothelial cells were assessed by qPCR and fluorescence staining, respectively. Vascular relaxation function of the mesenteric arteries was measured via wire myograph. Additionally, the immediate effect of IPA on blood pressure was monitored via the tail\u2010cuff method following IPA injection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The results demonstrated that IPA treatment significantly reduced the levels of inflammatory cytokines in the endothelial cells of DIO mice. IPA administration markedly increased NO levels in endothelial cells and enhanced the endothelium\u2010dependent vasodilation of mesenteric arteries. Mechanistically, IPA enhanced the phosphorylation of endothelial nitric oxide synthase (eNOS) via the PI3K\/Akt pathway, promoting the production and release of NO, thereby regulating blood pressure. This was further validated in eNOS\n                      <jats:sup>\u2212\/\u2212<\/jats:sup>\n                      mice.\n                    <\/jats:p>\n                  <\/jats:sec>\n
