摘要:


文题释义:

分子对接:分子对接技术原理源自19世纪Fisher的受体学说,发展至今人们认为药物与体内蛋白质分子即受体会发生相互作用而进行连接,相互作用的稳定性依赖于两者的空间匹配和能量匹配。该文采用的分子对接技术软件AutoDockTools通过建立药物配体和蛋白质受体结构的半柔性模型,分析判断配体和受体之间是否能够相互作用(空间匹配),并对作用稳定性进行评分(能量匹配)。
核因子κB信号通路:核因子κB(P 65)是参与关节炎症和组织破坏病理生理的重要转录因子,涉及滑膜、软骨、软骨下骨等多个组织。在骨关节炎中,激活关节软骨细胞表面的机械受体和细胞因子受体的细胞外基质降解产物、纤连蛋白分子、机械应力、老化因素和促炎细胞因子(如肿瘤坏死因子α或白细胞介素1β),均可导致核因子κB信号通路的激活,诱发或加重骨关节炎。


背景:菟丝子具有补肝肾、益精髓的功效,而骨关节炎的主要病机为肝肾亏虚,推测菟丝子与骨关节炎之间有一定的联系。

目的:基于网络药理学和分子对接的分析手段挖掘骨关节炎和菟丝子之间的潜在联系,对中药本草菟丝子的作用机制进行合理的推测与验证。
方法:先在中草药数据库TCMSP中筛选菟丝子的有效活性成分和作用靶点,另在疾病数据库GeneCards、OMIM、TTD中收集骨关节炎的相关基因;取交集后进行一系列分析,并筛选出核心基因;通过对核心基因的富集分析选择菟丝子作用于骨关节炎的通路,通过分子对接验证核心基因的作用,并依此选择合适的有效活性成分进行实验验证。

结果与结论:①筛选出11种菟丝子的有效活性成分,菟丝子和骨关节炎有66个交集靶点基因,后续筛选出12个核心基因,包括肿瘤坏死因子、白细胞介素1B、TP53、RACα丝氨酸/苏氨酸蛋白激酶(AKT1)、血管内皮生长因子A、基质金属蛋白酶9、前列腺素过氧合酶2、胱天蛋白酶3、表皮生长因子、过氧化物酶体增生激活受体γ、白细胞介素10、血管细胞黏附因子1;②对核心基因进行富集分析后,选择经典炎症通路核因子κB信号通路进行后续菟丝子缓解骨关节炎炎症的分析验证;根据各活性成分和通路核心基因前列腺素过氧合酶2进行分子对接后得到的结果,选择亲和力最高的芝麻素进行后续细胞实验验证,结果证实了菟丝子的有效成分芝麻素可以通过抑制白细胞介素1β诱导的核因子κB信号通路降低环氧合酶2的表达;③结果表明,菟丝子的活性有效成分芝麻素通过抑制白细胞介素1β诱导的核因子κB信号通路降低环氧合酶2的表达,达到改善骨关节炎炎症的作用,证实了菟丝子在骨关节炎方面的治疗效果。

Abstract: BACKGROUND: Semen cuscutae has the effect of tonifying the liver and kidney system and benefiting the essence. The main pathogenesis of osteoarthritis is deficiency of the liver and kidneys. Therefore, it is hypothesized that there is a link between semen cuscutae and osteoarthritis.
OBJECTIVE: To explore the potential relationship between osteoarthritis and semen cuscutae and validate the mechanism of semen cuscutae based on the network pharmacology and molecular docking analysis.
METHODS: First, the active ingredients and targets of semen cuscutae were screened in TCMSP, and the genes related to osteoarthritis were collected in the disease databases GeneCard’s, OMIM and TTD. The intersected genes were taken and then subjected to a series of analyses and screened for hub genes. Through the enrichment analysis of hub genes, the pathway of semen cuscutae acting on osteoarthritis was selected. The role of hub genes was verified by molecular docking. Therefore, the appropriate active ingredients of semen cuscutae were selected for experimental verification.
RESULTS AND CONCLUSION: There were 11 active ingredients of semen cuscutae, 66 intersection target genes of semen cuscutae and osteoarthritis, and 12 hub genes, including tumor necrosis factor, interleukin 1B, TP53, RAC-alpha serine/threonine protein kinase (AKT1), vascular endothelial growth factor A, matrix metalloproteinase 9, prostaglandin peroxidase 2, cystatinase 3, epidermal growth factor, peroxisome proliferator-activated receptor gamma, interleukin 10, vascular cell adhesion factor 1. After the enrichment analysis of the hub genes, the classical inflammatory pathway, nuclear factor-κB signaling pathway, was selected for subsequent validation of semen cuscutae to alleviate osteoarthritic inflammation. Through the results obtained after molecular docking of each active ingredient and the hub gene of the pathway prostaglandin peroxidase 2, sesamin with the highest affinity was selected for subsequent cell experiments, and the experimental results confirmed that sesamin, the active ingredient of semen cuscutae, could reduce the expression of cyclooxygenase 2 by inhibiting the nuclear factor-κB signaling pathway induced by interleukin-1β. To conclude, sesamin, the active ingredient of semen cuscutae, reduces the expression of cyclooxygenase 2 by inhibiting the nuclear factor-κB signaling pathway induced by interleukin-1β, thereby improving inflammation in osteoarthritis and expanding the therapeutic effect of semen cuscutae in osteoarthritis.

Key words: semen cuscutae, osteoarthritis, sesamin, nuclear factor-κB signaling pathway, cyclooxygenase 2, network pharmacology, molecular docking, inflammation
