摘要:

本文旨在探讨表没食子儿茶素没食子酸酯(EGCG)及其与β-环糊精(β-CD)的复合物(EGCG-β-CD)在抗破骨细胞生成及防治运动员骨质疏松中的作用差异。 通过高效液相色谱(HPLC)证实EGCG与β-CD成功包合,n(EGCG)∶nβ-CD)=1.89∶1。 利用核因子κB受体活化因子配体(RANKL)诱导的RAW264.7破骨细胞分化模型,通过抗酒石酸酸性磷酸酶(TRAP)染色、实时荧光定量PCR(qRT-PCR)及蛋白免疫印迹分析评估发现,在相同浓度(10 μmol/L)下,EGCG-β-CD复合物对破骨细胞分化的抑制效果显著强于EGCG,表现为成熟破骨细胞数量减少(P<0.05),破骨细胞标志基因NFATc1、CTSK、TRAP的mRNA及蛋白表达水平显著下调(P<0.001)。 研究表明,β-CD通过与EGCG形成特定化学计量比的包合物,协同提升其抗破骨细胞活性,为运动员骨质疏松的防治提供了新型植物活性成分递送策略。

Abstract:

The purpose of this study was to explore the effect of epigallocatechin gallate (EGCG) and its inclusion complex with β-cyclodextrin (β-CD) (EGCG-β-CD) on anti osteoclastogenesis and prevention of osteoporosis in athletes. The successful inclusion of EGCG and β-CD was confirmed by high-performance liquid chromatography (HPLC), and the binding stoichiometry was 1.89∶1. Using the RAW264.7 osteoclast differentiation model induced by RANKL, the tartrate resistant acid phosphatase (TRAP) staining, real-time fluorescent quantitative PCR (qRT-PCR) and Western blot analysis showed that at the same concentration (10 μmol/L), the inhibitory effect of EGCG-β-CD complex on osteoclast differentiation was significantly stronger than that of EGCG, which showed that the number of mature osteoclasts decreased (P<0.05), and the mRNA and protein expression levels of osteoclast marker genes NFATc1, CTSK and TRAP were significantly down regulated (P<0.001). Studies have shown that β-CD synergistically enhances its anti osteoclast activity by forming a specific stoichiometric inclusion complex with EGCG, providing a new delivery strategy of plant active ingredients for the prevention and treatment of osteoporosis in athletes.
