摘要: 本文探讨地榆成分3,3′-二甲氧基逆没食子酸-4-木糖苷(3,3′-dimethyl ellagic acid-4-xylycoside,DEAX)促进NIH3T3细胞增殖和迁移的作用及其分子机制。实验采用UPLC-DAD-TOF-MS对受试样品DEAX进行纯度分析和结构验证,然后采用MTS法考察不同 DEAX浓度和作用时间对NIH3T3细胞增殖的影响;应用划痕法检测不同浓度的DEAX对NIH3T3细胞迁移能力的影响,并分别使用ELISA和qRT-PCR检测DEAX处理NIH3T3细胞的TGF-β1和I型胶原蛋白的蛋白表达和mRNA表达水平。结果表明DEAX能显著促进NIH3T3细胞的增殖和迁移,提高TGF-β1和I型胶原蛋白mRNA表达及蛋白表达水平。提示DEAX可通过调控TGF-β1和I型胶原蛋白mRNA及蛋白表达水平,以促进NIH3T3细胞增殖和迁移,为阐明地榆促创面愈合的物质基础及其机理提供了实验依据。

Abstract: In present study,we aimed to investigate 3,3′-dimethyl ellagic acid-4-xylycoside (DEAX) of Sanguisorba officinalis L.whether it can promote the NIH3T3 cells proliferation & migration,also to explore its associated mechanism.The purity analysis and structure identification of DEAX were performed by Agilent 6230 UPLC-DAD-TOF-MS.The proliferations on NIH3T3 cells treated with the different DEAX concentrations and time points were detected by MTS assay,and the migrations of NIH3T3 cells treated with different DEAX concentrations were determined by scratch assay.The concentrations of hydroxyproline (HYP) and transforming grow factor-β1 (TGF-β1),and the mRNA expressions of TGF-β1and Collagen I were measured by ELISA and qRT-PCR,respectively.The results showed that DEAX could significantly promote the proliferation and migration of NIH3T3 cell (P<0.05 or P<0.01),and improve the protein and mRNA expressions of TGF-β1 and Collagen I (P<0.05 or P<0.01).These results indicated that DEAX could promote the proliferation and migration of NIH3T3 cell through improving the protein and mRNA expression of TGF-β1 and Collagen I,which provided scientific evidence for the material basis and mechanism of wound healing in Sanguisorba officinalis L.
