Abstract:Background: Korean Red ginseng extract (KRGE) has beneficial effects on the cardiovascular system by improving内皮细胞功能。然而,其对内皮细胞衰老的药理作用尚未清楚地阐明。因此,我们检查了效果和分子KRGE的ULAR机制在人脐静脉内皮细胞(HUVECS)的衰老中。
方法:
Results: Treatment of HUVECs with KRGE resulted in delayed onset and progression of senescence-associated characteristics, such as increased lysosomal acidicβ-galactosidase并降低端粒酶活性,血管生成功能障碍和异常细胞形态。 KRGE保留了抗性因子的水平,例如eNOS衍生的NO,MNSOD和Cyclins D和A:但是,它降低了促衰老因子的水平,例如ROS,活化的NF-B,内皮细胞炎症和p21表达。 KRGE的有益作用是由于HO-1的诱导以及MiR-155-5p的NF-B依赖性生物发生的抑制,这导致了ENOS的下调。 Moreover, treatment with inhibitors of HO-1, NF-B, and miR-155-5p abolished the anti-senescence effects of KRGE.
Conclusion: KRGE delayed or prevented HUVEC senescence through a signaling cascade involving the induction of HO-1, the inhibition of NF-B-dependent miR-155-5p生物发生以及eNOS/no轴活动的维持,这表明它可以预防与内皮衰老相关的血管疾病。
