摘要
背景:MiR-17-92簇由13号染色体上的MIR17HG编码,在脊椎动物中高度保守。已发表的文献证明miR-17-92簇集中调控肿瘤发生和转移。最近的研究表明,miR-17-92簇在内分泌系统中也起着新的作用。 目的:总结近期有关miR-17-92簇在骨,脂质和葡萄糖代谢中的生理和病理作用的发现。 结果:MiR-17-92簇通过调控成骨细胞和破骨细胞的分化和功能,在骨的发育和代谢中发挥重要调节作用。另外,miR-17-92簇几乎涉及脂质代谢的各个方面。最后但并非最不重要的是,miR-17-92簇与胰腺β细胞功能,1型糖尿病的发展和胰岛素抵抗密切相关。然而,miR-17-92簇是否参与骨,脂肪和葡萄糖代谢之间的交流还不清楚。 结论:越来越多的证据表明,miR-17-92簇通过多种信号途径在骨,脂质和葡萄糖代谢中起重要作用。充分了解其调节机制可能有助于理解一些代谢紊乱的临床和分子特征,如骨质疏松症,关节硬化症和糖尿病。它可能提供新的药物靶点来预防和治疗这些疾病。

摘要: Background: MiR-17-92 cluster is coded by MIR17HG in chromosome 13, which is highly conserved in vertebrates. Published literatures have proved that miR-17-92 cluster critically regulates tumorigenesis and metastasis. Recent researches showed that the miR-17-92 cluster also plays novel functions in the endocrine system.
Objective: To summarize recent findings on the physiological and pathological roles of miR-17-92 cluster in bone, lipid and glucose metabolisms.
Results: MiR-17-92 cluster plays significant regulatory roles in bone development and metabolism through regulating the differentiation and function of osteoblasts and osteoclasts. In addition, miR-17- 92 cluster is nearly involved in every aspect of lipid metabolism. Last but not the least, the miR-17-92 cluster is closely bound up with pancreatic beta cell function, development of type 1 diabetes and insulin resistance. However, whether miR-17-92 cluster is involved in the communication among bone, fat and glucose metabolisms remains unknown.
Conclusion: Growing evidence indicates that miR-17-92 cluster plays significant roles in bone, lipid and glucose metabolisms through a variety of signaling pathways. Fully understanding its modulating mechanisms may necessarily facilitate to comprehend the clinical and molecule features of some metabolic disorders such as osteoporosis, arthrosclerosis and diabetes mellitus. It may provide new drug targets to prevent and cure these disorders.
