文题释义:
佛手柑内酯:是一种新型的抗炎、降脂的药物,原料佛手为生物学学科香豆素类的一味中药,主治肝气郁结之胁痛、胸闷;肝胃不和、脾胃气滞之脘腹胀痛、嗳气,价格便宜,提取方便,具有显著的抗心力衰竭、抗心律失常、降低胆固醇、抑制血管平滑肌增殖、改善胰岛素抵抗、抗血小板及抗炎等作用。
人脐静脉内皮细胞衰老模型:成功复制建立了60 μmol/L的双氧水诱导的人脐静脉内皮细胞的衰老模型,可以显著地由不同浓度的佛手柑内酯缓解,其延缓内皮细胞的衰老与哺乳动物雷帕霉素靶蛋白(mTOR)信号通路密切相关。

摘要
背景:
有效的中医药治疗可以缓解内皮细胞的衰老,传统的中医药提取较困难,佛手柑内酯提纯简练,价格经济,关于佛手柑内酯在延缓内皮细胞衰老的研究中尚未见报道。
目的:观察佛手柑内酯对双氧水诱导人脐静脉内皮细胞衰老的影响。
方法:将人脐静脉内皮细胞采用过氧化氢处理建立衰老细胞模型,并用0.1,1,10 μmol/L佛手柑内酯预处理。通过Western blot法检测各处理组pRb,pAmpk,pS6,LC3-Ⅱ,Beclin-1蛋白,β-半乳糖甘酶染色确定各组衰老细胞数,细胞免疫荧光检测pS6阳性细胞数。
结果与结论:①Western blot结果、β-半乳糖苷酶染色法和免疫荧光检测结果:采用佛手柑内酯后预处理的衰老细胞模型中,pS6,pRb蛋白表达降低,β-半乳糖苷酶染色阳性细胞数和免疫荧光pS6阳性细胞数减少,pAmpk,Beclin-1,LC3-Ⅱ蛋白表达升高(P < 0.05);②结果说明,佛手柑内酯预处理对双氧水诱导的人脐静脉内皮细胞有一定抗衰老作用。

Abstract:

BACKGROUND: The effective treatment of traditional Chinese medicine can alleviate the aging of endothelial cells. Traditional Chinese medicine is difficult to extract, and in contrast, Bergapten is cheap and easily purified, but its antisenescence is little reported.
OBJECTIVE: To explore the effect of Bergapten on H2O2-induced senescence of human umbilical vein endothelial cells.
METHODS: Human umbilical vein cell aging model was induced by H2O2, and pretreated with 0.1, 1 and 10 μmol/L Bergapten, respectively. Expressions of pRb, pAmpk, pS6, LC3-II, and Beclin-1 protein in each group were detected by western blot assay, and the number of aging cells and pS6-positive cells was determined by β-galactosidase staining and immunofluorescence, respectively.
ESULTS AND CONCLUSION: After Bergapten pretreatment, pS6 and pRb protein expressions were significantly downregulated, and the number of cells positive for β-galactosidase and pS6 was significantly decreased, while protein expressions of pAmpk, Beclin-1and LC3-II were significantly increased (P < 0.05). These findings suggest that Bergapten is able to delay the H2O2-induced aging of human umbilical vein endothelial cells
