초록

Chrysanthemum coronarium L (CC)., a leafy vegetable, has various biological properties, including anti-oxidative, anti-inflammatory, antiproliferative, and anti-osteoporosis effects. However, the vascular protective effects of CC remain poorly understood. In this study, we identified the vascular protective effect of CC against ferroptosis in aortic thoracic smooth muscle A7r5 cells. The vascular protective effects of CC against erastin (Era)-induced A7r5 cells were assessed by estimating cell viability, glutathione (GSH) levels, lipid peroxidation, mitochondrial morphological change, and using western blot analysis. The CC treatment effectively ameliorated Era-induced ferroptotic cytotoxicity, including cellular death. The treatment also suppressed mitochondrial morphological change in the Era-induced A7r5 cells. CC significantly regulated Era-induced abnormal mechanisms related to GSH, lipid peroxidation, cysteine/glutamate antiporter SLC7A11(xCT), and glutathione peroxidase 4 (GPX4) protein expression in A7r5 cells. In conclusion, these findings indicate that CC shows potential as a functional food supplement, nutraceutical, or medicinal food, with protective effects with respect to vascular health by regulating ferroptosis.
