骨再生是骨质疏松症(OP)治疗的一个有前途的途径。它包括几个过程,如间充质干细胞的成骨分化以及成骨细胞的增殖和成熟。许多表观遗传机制参与骨再生的调节,包括DNA甲基化、组蛋白修饰和microRNA调节。这些过程在功能上修饰基因组而不改变核苷酸序列,导致基因表达的变化。过去的研究已经确定了表观遗传机制在骨代谢中的重要性。本文就近年来这一领域的研究进展作一综述,以期更好地了解表观遗传机制如何参与骨再生和内环境稳定。这将为我们研究骨质疏松症治疗的临床前景提供一个新的目标。
Bone regeneration is a promising avenue for osteoporosis (OP) treatment. It consists of several procedures, such as the osteogenic differentiation of mesenchymal stem cells as well as the proliferation and maturation of osteoblasts. Many epigenetic mechanisms are involved in the modulation of bone regeneration, including DNA methylation, histone modifications, and microRNA regulation. These processes functionally modify the genome without changing the nucleotide sequence, leading to changes in gene expression. Past studies have identified the importance of epigenetic mechanisms in bone metabolism. In this review, we will summarize the recent studies in this field to obtain a better understanding of how epigenetic mechanisms participate in bone regeneration and homeostasis. This will provide us a new target for investigating clinical perspectives of osteoporosis treatment.
