摘要:




文题释义:
异银杏素:是一种来源于银杏提取物的黄酮类化合物,具有广泛的抗癌活性,并且能通过增强自噬来清除活性氧。
破骨细胞分化:破骨细胞是大型、多核的具有骨吸收功能的细胞,通过巨噬细胞集落刺激因子和核因子κB受体活化因子配体的刺激从髓系细胞分化而来。
活性氧:泛指氧来源的自由基和非自由基,在正常情况下,生理水平的活性氧能调控细胞内环境稳态、信号转导、增殖分化等生理活动,而高水平的活性氧则破坏氧化还原平衡,可致氧化损伤、功能障碍甚至细胞死亡。

背景:在骨重塑过程中,骨形成和骨吸收在空间和时间上是协调的,涉及破骨细胞和成骨细胞之间错综复杂的相互作用。异银杏素是在银杏中发现的一种黄酮类化合物,具有广泛的抗癌活性和抗活性氧活性,然而异银杏素对破骨细胞分化的影响尚不清楚。
目的:探讨异银杏素对破骨细胞分化的影响和作用机制。
方法:以小鼠骨髓来源巨噬细胞为研究对象,CCK-8细胞毒性实验检测不同浓度异银杏素对骨髓来源巨噬细胞活力的影响。使用巨噬细胞集落刺激因子和核因子κB受体活化因子配体诱导骨髓来源巨噬细胞向破骨细胞分化,网络药理学和分子对接、分子动力学模拟用于预测异银杏素对破骨细胞分化影响的进程和靶点;抗酒石酸酸性磷酸酶染色和F-actin染色检测异银杏素对破骨细胞分化和功能的影响;Western blot及RT-PCR检测异银杏素对破骨细胞分化、活性氧相关和PI3K/AKT通路基因、蛋白表达的影响;荧光探针检测细胞活性氧和线粒体活性氧水平;流式细胞术检测细胞活性氧水平。
结果与结论:①网络药理学结果显示异银杏素主要通过PI3K/AKT通路、细胞对药物和缺氧的反应影响破骨细胞分化,GSK3β、ESR1、MCL1及CCNA2等是关键靶点;②CCK-8和抗酒石酸酸性磷酸酶染色结果表明异银杏素浓度为8 μmol/L时抑制破骨细胞分化的效果最显著,F-actin结果显示异银杏素以浓度依赖性地抑制破骨细胞骨架肌动蛋白环形成;③分子动力学模拟表明异银杏素与破骨细胞分化标志蛋白(NFATc1、c-Fos、CTSK和MMP9)存在较稳定的结合,Western blot和RT-PCR结果显示异银杏素抑制破骨细胞分化标志蛋白和基因(NFATc1、c-Fos、CTSK和MMP9)的表达;④Western blot结果显示异银杏素抑制PI3K、AKT、GSK3β的磷酸化水平,激活PI3K/AKT-GSK3β通路抑制破骨细胞分化;⑤活性氧检测结果显示异银杏素显著减少核因子κB受体活化因子配体诱导的细胞活性氧和线粒体活性氧的产生,抑制骨髓来源巨噬细胞向破骨细胞分化。

Abstract: BACKGROUND: During bone remodeling, bone formation and bone resorption are spatially and temporally coordinated, involving intricate interactions between osteoclasts and osteoblasts. Isoginkgetin, a flavonoid found in Ginkgo biloba, has a wide range of anticancer activity and anti-reactive oxygen species activity; however, the effect of isoginkgetin on osteoclast differentiation is unknown.
OBJECTIVE: To study the effect and mechanism of action of isoginkgetin on osteoclastogenesis.
METHODS: In vitro studies were performed on mouse bone marrow-derived macrophages, and cell counting kit-8 cytotoxicity assay was used to detect the effect of isoginkgetin on cell viability of bone marrow-derived macrophages. Macrophage colony-stimulating factor and receptor activator of nuclear factor kappa-B ligand were used to induce the differentiation of bone marrow-derived macrophages to osteoclasts. Network pharmacology and molecular docking and molecular dynamics simulations were used to predict the processes and targets of the effects of isoginkgetin on the differentiation of osteoclasts. Tartrate-resistant acid phosphatase staining and F-actin staining were used to detect the effects of isoginkgetin on the differentiation and function of osteoclasts. Western blot and RT-PCR were used to detect the effects of isoginkgetin on the expression of genes and proteins related to osteoclast differentiation, reactive oxygen species, and PI3K/AKT pathways. Fluorescent probes were used to detect cellular and mitochondrial reactive oxygen species levels. Flow cytometry technology was used to detect reactive oxygen species levels in cells. 
RESULTS AND CONCLUSION: (1) Network pharmacology results showed that isoginkgetin affected osteoporosis mainly through the PI3K-AKT pathway and cellular response to drugs and hypoxia, and GSK3β, ESR1, MCL1 and CCNA2 were the key targets. (2) Cell counting kit-8 and tartrate-resistant acid phosphatase staining results showed that isoginkgetin at 8 μmol/L had the most significant inhibitory effect on osteoclastogenesis in vitro, and F-actin results showed that isoginkgetin inhibited osteoclast cytoskeletal actin ring formation in a concentration-dependent manner. (3) Molecular dynamics simulations showed that isoginkgetin bound well to osteoclastogenesis marker proteins (NFATc1, c-Fos, CTSK, and MMP9). Western blot and RT-PCR results indicated that isoginkgetin inhibited the expression of osteoclastogenesis marker proteins and genes (NFATc1, c-Fos, CTSK, and MMP9). (4) Western blot results showed that isoginkgetin inhibited the phosphorylation level of PI3K/AKT/GSK3β and suppressed osteoclastogenesis by activating the PI3K-AKT-GSK3β pathway. (5) The results of reactive oxygen species assay showed that isoginkgetin significantly reduced receptor activator of nuclear factor kappa-B ligand-induced cellular and mitochondrial reactive oxygen species production, and inhibited the differentiation of bone marrow-derived macrophages to osteoclasts.
