摘要:
骨癌痛(bone cancer pain, BCP)发生、发展机制复杂,目前仍旧困扰临床。在转录后水平起调控作用的微RNA(microRNA, miRNA)可能参与BCP过程。因此,寻找参与BCP发生、发展相关的特定miRNA与标志物,将为BCP治疗及临床检测、诊断提供帮助。文章综述近期研究,阐述miRNA如何调控破骨细胞活化,促进骨吸收进而导致BCP的形成;miRNA如何调控不同的信号通路[蛋白激酶A/环磷腺苷效应元件结合蛋白信号通路(cAMP‑response element binding protein, CREB)、CXC趋化因子配体12(chemokine C‑X‑C motif ligand 12, CXCL12)/趋化因子CXC基序受体4(chemokine C‑X‑C motif receptor 4, CXCR4)信号通路等]参与BCP的形成和发展;miRNA如何通过调控神经元可塑性和改变神经元离子通道的表达发挥BCP调控作用,以期为探明BCP的发生发展机制、转化临床提供帮助。

Abstract: At present, since the mechanism of occurrence and development of bone cancer pain (BCP) is sophisticated, it is still perplexing in the clinical practice. MicroRNA (miRNA), which plays a regulatory role at the post‑transcriptional level, may be involved in the BCP process. Therefore, the search for unique miRNA and biomarkers involved in the occurrence and development of BCP will be helpful for the treatment, clinical detection and diagnosis. In this paper, we reviewed recent researches and described how miRNA regulate osteoclast activation, promoted bone resorption and led to the formation of BCP. We also described how miRNA regulate different signaling pathways [chemokine C‑X‑C motif ligand 12 (CXCL12)/chemokine C‑X‑C motif receptor 4 (CXCR4) signaling pathway, protein kinase A/cAMP‑response element binding protein (CREB) signaling pathway, et al] that involved in the formation and development of BCP and how miRNA plays a role in BCP regulation by regulating neuronal plasticity and changing the expression of neuronal ion channels. Subsequently, This review summarizes the occurrence and development mechanism of BCP and provides help for clinical transformation.
