摘要
背景:核转录因子κB信号通路在骨质疏松症的发病中扮演着重要的角色。近年来,大量的研究表明萜类中药单体化合物可以通过调控核转录因子κB信号通路,抑制骨吸收细胞的活性,促进骨形成细胞的分化,从而降低骨吸收并增加骨形成,对骨质疏松症具有一定的预防和治疗作用。目的:通过对国内外文献的分析和总结,深入研究核转录因子κB信号通路与骨质疏松症的关系,并对萜类中药单体化合物调控核转录因子κB信号通路防治骨质疏松症的作用机制进行阐明,同时对靶向调控核转录因子κB信号通路防治骨质疏松的萜类中药单体化合物进行系统性归纳。方法:由2名研究员根据拟定的纳入及排除标准以“NF-κB,骨质疏松症,成骨细胞,破骨细胞,血管生成,中药,萜类化合物”等为检索词检索中国知网数据库,以“NF-κB,osteoporosis,Osteoblasts,Osteoclasts,Angiogenesis,traditional Chinese medicine,terpenoid”等为检索词检索PubMed数据库相关文献,检索时间为建库至2022年12月,再通过第3名研究员对文献进行汇总和整理,最终纳入75篇文献进行系统性综述。结果与结论:①核转录因子κB信号通路能通过调控成骨细胞、破骨细胞的分化和增殖,以及血管生成,介导骨质疏松症的发病与进展。②核转录因子κB信号通路对成骨细胞的增殖和分化具有负调控的作用,激活核转录因子κB信号通路能增强破骨细胞的活性,抑制成骨细胞的生长,进而抑制代偿骨的生成保持骨稳态,但是过度激活核转录因子κB信号通路则会导致骨质疏松症。③核转录因子κB信号通路通过上调血管生成素1、血小板源性生长因子BB及血管内皮生长因子等细胞因子的表达水平,促进骨内血管生长,参与“血管生成-成骨”偶联。④萜类中药单体化合物在组织工程领域中具有促进骨细胞的增殖和分化,进而促进骨组织生长和修复的作用。⑤萜类中药单体化合物可以通过抑制核转录因子κB抑制蛋白降解,阻断核转录因子κB/P65蛋白磷酸化及核转位等过程,进而减弱核转录因子κB信号通路的传导,促进成骨细胞分化,抑制破骨细胞形成,起到防治骨质疏松的作用。⑥目前,萜类中药单体化合物调控核转录因子κB信号通路防治骨质疏松症的研究主要是基于体外细胞实验和动物模型,对于人体内复杂的生理和病理过程尚缺乏相关研究,未来需要开展更多的临床研究,进一步明确核转录因子κB信号通路参与干预骨质疏松症的作用机制和疗效。
BACKGROUND:The nuclear factor-κB signaling pathway plays an important role in the pathogenesis of osteoporosis.In recent years,increasing studies have shown that terpenoid herbal monomer compounds can inhibit the activity of bone resorbing cells and promote the differentiation of bone forming cells via the nuclear factor-κB signaling pathway,thus reducing bone resorption and increasing bone formation,which has certain preventive and therapeutic effects on osteoporosis.OBJECTIVE:By analyzing and summarizing the domestic and international literature,to investigate the relationship between nuclear factor-κB signaling pathway and osteoporosis in depth,elucidate the mechanism of terpenoid monomer compounds in regulating the nuclear factor-κB signaling pathway to prevent osteoporosis,and systematically summarize the terpenoid monomer compounds targeting to regulate the nuclear factor-κB signaling pathway to prevent osteoporosis.METHODS:According to the proposed inclusion and exclusion criteria,two researchers searched for relevant articles published from database inception to December 2022 in CNKI and PubMed using the search terms“NF-κB,osteoporosis,osteoblasts,osteoclasts,angiogenesis,traditional Chinese medicine,terpenoid”in Chinese and English,respectively.A third researcher summarized and organized the literature and 75 articles were finally included for a systematic review.RESULTS AND CONCLUSION:The nuclear factor-κB signaling pathway mediates the onset and progression of osteoporosis by regulating the differentiation and proliferation of osteoblasts and osteoclasts,as well as angiogenesis.Activation of the nuclear factor-κB signaling pathway negatively regulates the proliferation and differentiation of osteoblasts.Activation of the nuclear factor-κB signaling pathway enhances osteoclast activity and inhibits osteoblast growth,thereby inhibiting compensatory bone production to maintain bone homeostasis.However,over-activation of the nuclear factor-κB signaling pathway can lead to osteoporosis.The nuclear factor-κB signaling pathway is involved in the“angiogenesis-osteogenesis”coupling by upregulating the expression levels of cytokines such as angiopoietin-1,platelet-derived growth factor BB and vascular endothelial growth factor,which promote the growth of blood vessels in bone.The terpenoid herbal monomer compounds are used in the field of tissue engineering to promote the proliferation and differentiation of bone cells,thereby promoting the growth and repair of bone tissue.Terpenoid herbal monomer compounds can prevent and treat osteoporosis by inhibiting the degradation of nuclear factor-κB inhibitor,blocking nuclear factor-κB/p65 phosphorylation and nuclear translocation,thereby weakening the nuclear factor-κB signaling pathway,promoting osteoblast differentiation and inhibiting osteoclast formation.Currently,research on the regulation of nuclear factor-κB signaling pathway by monomeric compounds of terpenoids to prevent osteoporosis is mainly based on in vitro cellular experiments and animal models,and there is a lack of research on the complex physiological and pathological processes in humans.In the future,more clinical trials and studies are needed to further clarify the mechanism of action and efficacy of the nuclear factor-κB signaling pathway involved in the intervention of osteoporosis.
