MicroRNA(miRNAs)是一类短RNA分子,其通过与靶mRNA相互作用并随后沉默基因表达来介导基因活性的调节。越来越清楚的是,miRNAs调节骨生物学的许多不同方面,包括骨形成和骨吸收过程。由于临床上对发现控制过度骨吸收的新范例的兴趣,最近已经研究了miRNAs在破骨细胞中的特异性作用,如在包括老化、雌激素剥夺、癌症转移或糖皮质激素使用的多种条件下观察到的。因此,了解miRNAs在骨细胞分化过程中的作用至关重要。在这篇综述中,我们强调并讨论了miRNA在破骨细胞中功能的一般方面,包括令人兴奋的数据表明,封装在细胞外囊泡(EV)中的miRNA,无论是来自破骨细胞,还是从不同的位点向破骨细胞发出信号,在骨稳态中具有重要作用。
MicroRNAs (miRNAs) are a class of short RNA molecules that mediate the regulation of gene activity through interactions with target mRNAs and subsequent silencing of gene expression. It has become increasingly clear the miRNAs regulate many diverse aspects of bone biology, including bone formation and bone resorption processes. The role of miRNAs specifically in osteoclasts has been of recent investigation, due to clinical interest in discovering new paradigms to control excessive bone resorption, as is observed in multiple conditions including aging, estrogen deprivation, cancer metastases or glucocorticoid use. Therefore understanding the role that miRNAs play during osteoclastic differentiation is of critical importance. In this review, we highlight and discuss general aspects of miRNA function in osteoclasts, including exciting data demonstrating that miRNAs encapsulated in extracellular vesicles (EVs) either originating from osteoclasts, or signaling to osteoclast from divergent sites, have important roles in bone homeostasis.
