项目摘要
Effects of elastin peptide from fish ductus arteriosus on vascular and cutaneous function was investigated using spontaneously hypertensive rats (SHR) or hairless rats. Chronic administration of elastin peptide to SHR resulted in ameriolation of endothelial injury and preservation of arterial elasticity. Prolyl glysin, a degradation product of elastin peptide, may be key sequence of elastin peptide, since continuous infusion of PG to SHR was effective to prevent endothelial injury. In cultured endothelial cells, expression of ICAM-1 and Caveoin was depressed by elastin peptide and PG. In rat model with ultraviolet irradiation, on the other hand, skin elasticity was higher in rats which administered elastin peptide to skin of rats rather than control rats.These results suggest that elastin peptide from fish arteriosus was effective for preservation of elasticity not only in artery but also in skin.
使用自发性高血压大鼠(SHR)或无毛大鼠研究了来自鱼动脉导管的弹性蛋白肽对血管和皮肤功能的影响。对 SHR 长期施用弹性蛋白肽可改善内皮损伤并保持动脉弹性。脯氨酰甘氨酸是弹性蛋白肽的降解产物,可能是弹性蛋白肽的关键序列,因为向SHR持续输注PG可有效预防内皮损伤。在培养的内皮细胞中,弹性蛋白肽和 PG 抑制 ICAM-1 和 Caveoin 的表达。另一方面,在紫外线照射的大鼠模型中,给予大鼠皮肤弹性蛋白肽的大鼠的皮肤弹性比对照大鼠更高。这些结果表明,来自鱼动脉的弹性蛋白肽不仅对动脉的弹性保持有效但也存在于皮肤中。
