Abstract

Simple Summary

Osteoporosis is a disease that is characterized by bone mass loss and microarchitecture deterioration, due to alterations in the bone remodeling mechanism, which must maintain a balance between bone resorption and formation. In recent years, it has been described that microRNAs (miRNAs) play an essential role in bone activation, differentiation, and homeostasis, since they can act as regulators of genes that participate in different signaling pathways. Therefore, altered expression of distinct miRNAs can affect the pathology of bone diseases such as osteoporosis. This review analyzes the current knowledge on the role of miRNAs in the various signaling pathways that maintain bone homeostasis in humans.

Abstract

Bone remodeling, crucial for maintaining the balance between bone resorption and formation, relies on the coordinated activity of osteoclasts and osteoblasts. During osteoclastogenesis, hematopoietic stem cells (HSCs) differentiate into the osteoclast lineage through the signaling pathways OPG/RANK/RANKL. On the other hand, during osteoblastogenesis, mesenchymal stem cells (MSCs) differentiate into the osteoblast lineage through activation of the signaling pathways TGF-β/BMP/Wnt. Recent studies have shown that bone remodeling is regulated by post-transcriptional mechanisms including microRNAs (miRNAs). miRNAs are small, single-stranded, noncoding RNAs approximately 22 nucleotides in length. miRNAs can regulate virtually all cellular processes through binding to miRNA-response elements (MRE) at the 3’ untranslated region (3′UTR) of the target mRNA. miRNAs are involved in controlling gene expression during osteogenic differentiation through the regulation of key signaling cascades during bone formation and resorption. Alterations of miRNA expression could favor the development of bone disorders, including osteoporosis. This review provides a general description of the miRNAs involved in bone remodeling and their significance in osteoporosis development.
