摘要: 利用人粪便中分离的一株长双歧杆菌ZJ1株胞外多糖提取物(ZJ1-EPS),分别采用丙酮醛(MGO)诱导牛血清白蛋白(BSA)和人皮肤细胞非酶糖基化(AGEs)模型和葡萄糖诱导斑马鱼AGEs模型,探究ZJ1-EPS抑制AGEs的作用和机制。结果表明,ZJ1-EPS对AGEs生成有明显的抑制作用,同时可显著抑制角质细胞和成纤维细胞中丙酮醛(MGO)诱导的MMP-1表达,促进胶原蛋白的表达。研究揭示了双歧杆菌胞外多糖提取物具有抑制AGEs生成的作用,提示其用于皮肤抗衰的作用机制和应用潜力。

Abstract: The extracellular polysaccharide extract (ZJ1-EPS) ofBifidobacterium longumZJ1 strain isolated from the feces of centenarians was used to explore the effect and mechanism of ZJ1-EPS inhibition of AGEs by pyruvaldehyde (MGO)-induced bovine serum albumin (BSA) and non-enzymatic glycosylation (AGEs) in human skin cells and glucose-induced zebrafish AGEs, respectively. The results showed that ZJ1-EPS had a significant inhibitory effect on the formation of products in the middle and late stages of protein non-enzymatic glycosylation. This study revealed that the exopolysaccharide extract ofBifidobacteriumhas the effect of inhibiting the production of AGEs, suggesting its mechanism of action and application potential for skin anti-aging.

Key words: Bifidobacterium longum, extracellular polysaccharides, non-enzymatic glycosylation, skin cells, zebrafish
