Abstract:
Osteogenic differentiation originating from mesenchymal stem cells (MSCs) requires tight co-ordination of transcriptional factors, signaling pathways and biomechanical cues. Dysregulation of such reciprocal networks may influence the proliferation and apoptosis of MSCs and osteoblasts, thereby impairing bone metabolism and homeostasis. An increasing number of studies have shown that long non-coding (lnc)RNAs are involved in osteogenic differentiation and thus serve an important role in the initiation, development, and progression of bone diseases such as tumors, osteoarthritis and osteoporosis. It has been reported that the lncRNA, maternally expressed gene 3 (MEG3), regulates osteogenic differentiation of multiple MSCs and also acts as a critical mediator in the development of bone formation and associated diseases. In the present review, the proposed mechanisms underlying the roles of MEG3 in osteogenic differentiation and its potential effects on bone diseases are discussed. These discussions may help elucidate the roles of MEG3 in osteogenic differentiation and highlight potential biomarkers and therapeutic targets for the treatment of bone diseases.
Insights
Maternally expressed gene 3 (MEG3) long non-coding RNA plays a key role in bone formation by regulating mesenchymal stem cell differentiation. Understanding MEG3

- * Molecular Biology and Genetics
- * Stem Cell Biology
- * Bone Metabolism and Disease
Background:
- * Osteogenic differentiation of mesenchymal stem cells (MSCs) is a complex process involving transcriptional factors, signaling pathways, and biomechanical cues.
- * Disruptions in these networks can affect MSC and osteoblast proliferation and apoptosis, leading to impaired bone metabolism and homeostasis.
- * Long non-coding RNAs (lncRNAs) are increasingly recognized for their involvement in osteogenic differentiation and bone diseases like osteoporosis and osteoarthritis.
Purpose of the Study:
- * To review the proposed mechanisms by which the lncRNA maternally expressed gene 3 (MEG3) influences osteogenic differentiation.
- * To discuss the potential role of MEG3 in the development and progression of bone diseases.
- * To highlight MEG3 as a potential biomarker and therapeutic target for bone-related conditions.
Main Methods:
- * Comprehensive literature review of studies investigating the role of MEG3 in osteogenic differentiation.
- * Analysis of proposed molecular mechanisms and signaling pathways involving MEG3.
- * Examination of evidence linking MEG3 to bone diseases such as tumors, osteoarthritis, and osteoporosis.
Main Results:
- * MEG3 is confirmed to regulate osteogenic differentiation in various MSC types.
- * MEG3 acts as a critical mediator in bone formation processes.
- * Dysregulation of MEG3 is implicated in the pathogenesis of several bone diseases.
Conclusions:
- * MEG3 plays a significant role in osteogenic differentiation and bone homeostasis.

Types of RNA
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in the regulation of gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.
