Wheat oligopeptides (WOPs), small peptide mixtures derived from the enzymatic hydrolysis of wheat protein, contain peptides of varying molecular weights. Although previous studies have shown that plant\u2010derived protein peptides can lower blood pressure, systematic research on WOPs and their antihypertensive mechanisms remains relatively limited. The aim of this study was to evaluate the antihypertensive efficacy of WOPs kDa and to investigate its mechanisms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS<\/jats:title>\n                    <jats:p>\n                      The study found that WOPs demonstrated potent angiotensin\u2010converting enzyme (ACE) inhibitory activity, achieving a 77% inhibition rate at 2.5\u2009mg\u00b7mL\n                      <jats:sup>\u22121<\/jats:sup>\n                      , and that they induced marked reductions in diastolic (DBP), systolic (SBP), and mean arterial (MBP) blood pressure in spontaneously hypertensive rats (SHRs). WOPs\u00a0reduced oxidative stress\u2010induced damage in the kidneys and myocardium of the SHR by activating the nuclear factor erythroid 2\u2013related factor 2 (Nrf2)\/Kelch\u2010like ECH\u2010associated protein 1 (Keap1) signaling pathway. They also lowered serum levels of inflammatory factors in SHRs: tumor necrosis factor\u2010alpha (TNF\u2010\n                      <jats:italic>\u03b1<\/jats:italic>\n                      ), interleukin\u20106 (IL\u20106), interleukin\u20101 beta (IL\u20101\n                      <jats:italic>\u03b2<\/jats:italic>\n                      ), endothelin\u20101 (ET\u20101), vascular endothelial growth factor A (VEGF\u2010A), and cluster of differentiation 62E (CD62E). WOPs also alleviated kidney and myocardial tissue damage caused by hypertension through the activation of the phosphoinositide 3\u2010kinase\/protein kinase B (PI3K\/AKT) signaling pathway and regulation of angiotensin II type 1 receptor (AT1R), ACE, and endothelial nitric oxide synthase (eNOS) signaling proteins, thereby contributing to blood pressure regulation.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>CONCLUSION<\/jats:title>\n                    <jats:p>\n                      WOPs demonstrated notable antihypertensive effects\n                      <jats:italic>in vivo<\/jats:italic>\n                      .
