- Abstract: Ferroptosis may play an essential role in lipid peroxidation and endothelial dysfunction of aortic endothelial cells (ECs) in type 2 diabetes mellitus (T2DM) with atherosclerosis (AS). Hydroxysafflor yellow A (HSYA) has shown substantial antioxidant stress and anti-ferroptosis. This study confirms whether HSYA improves symptoms in a mouse model of T2DM/AS and elucidates the underlying mechanisms. ApoE-/- mice were fed with high fat combined with 30 mg/kg streptozotocin to establish a T2DM/AS model. Then mice were treated with intraperitoneal injections of 2.25 mg/kg HSYA for 12 weeks. Human Umbilical Vein Endothelial cells (HUVEC) induced by 33.3 mM d-glucose +100 μg/mL ox-LDL were used to construct a high lipid and high glucose cell model treated with 25 μM HSYA. The changes in oxidative stress- and ferroptosis-related markers were detected, and the regulatory effect of HSYA on the miR-429/SLC7A11 was also verified. Normal ApoE-/- mice or HUVEC cells were used as the control group. HSYA effectively reduced atherosclerotic plaque formation in the T2DM/AS mouse model and inhibited HUVEC ferroptosis, such as upregulating GSH-Px, SLC7A11 and GPX4, but inhibited ACSL4. Furthermore, HSYA also downregulated the expression of miR-429, which further regulated SLC7A11 expression. After miR-429 mimic or SLC7A11 siRNA transfection in the HUVEC, the antioxidative stress and anti-ferroptosis effects of HSYA were significantly abolished. HSYA is expected to become an important health drug to prevent the occurrence and development of T2DM/AS. [ABSTRACT FROM AUTHOR]
