Summary
Non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), are key epigenetic regulators in bone biology. Understanding their roles offers new therapeutic targets for skeletal disorders.
Area of Science:
- Epigenetics
- Molecular Biology
- Skeletal Biology
Background:
- Non-coding RNAs (ncRNAs) are crucial epigenetic regulators of gene expression in eukaryotes.
- MicroRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are abundant regulatory ncRNAs with distinct yet interrelated mechanisms.
- The role of ncRNAs, particularly lncRNAs, in skeletal biology is an emerging area of research.
Purpose of the Study:
- To review current knowledge on ncRNA regulation in bone biology, focusing on miRNAs and lncRNAs.
- To outline guiding principles for investigating ncRNA control of bone tissue formation.
- To highlight potential therapeutic applications of ncRNAs for skeletal disorders.
Main Methods:
- Literature review of studies on miRNA and lncRNA in osteoblast and osteoclast differentiation.
- Analysis of in vivo gain- and loss-of-function studies.
- Discussion of approaches for understanding lncRNA functions in bone.
Main Results:
- Over 1100 publications link miRNAs to bone biology and pathologies.
- Specific miRNAs regulate osteogenic and resorptive cell differentiation, supporting bone homeostasis.
- Recent advances illuminate miRNA biogenesis regulation impacting osteogenic lineage commitment.
Conclusions:
- ncRNAs play significant roles in skeletal development and homeostasis.
- Further research is needed to understand the complex functions of lncRNAs in bone.
- Targeting miRNAs and lncRNAs presents promising therapeutic avenues for skeletal diseases.

01:37Epigenetic Regulation
4.3K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

10.2K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

01:17Hormones and Bone Tissue
4.3K
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
