dc.description.abstractEndothelial cells (ECs) are vital for vascular homeostasis, regulating blood flow, nutrient exchange, and immune responses. EC dysfunction contributes to diseases such as type 2 diabetes, atherosclerosis, and hypertension, with sex-specific differences in disease progression. Our lab previously observed sex differences in the response of adipose tissue ECs (ATECs) to high-fat diet-induced metabolic and oxidative stress, with females showing more favorable outcomes. Female ECs express higher Forkhead Box O1 (FoxO1) levels than males, suggesting sex-specific FoxO1 regulation. To explore this, male and female ECs were exposed to metabolic and oxidative stress, and FoxO1 subcellular localization and post-translational modifications were assessed. Male ECs showed increased FoxO1 phosphorylation and cytoplasmic localization, while females retained FoxO1 in the nucleus, supporting enhanced transcriptional potential. These findings highlight sex-dependent FoxO1 regulation, offering insights into molecular mechanisms driving sex differences in vascular health.
