Current Osteoporosis Reports
|April 29, 2023
Summary
Circular RNAs (circRNAs) are stable molecules with emerging roles in bone health. Research highlights their involvement in osteoblast and osteoclast function and their potential as osteoporosis biomarkers.
Area of Science:
- Molecular Biology
- Genetics
- Biochemistry
Background:
- Circular RNAs (circRNAs) are covalently closed RNA molecules with high stability.
- They are increasingly recognized for their regulatory roles in cellular processes.
- Their specific functions in bone metabolism are an active area of research.
Purpose of the Study:
- To review the emerging roles of circRNAs in osteoporosis.
- To discuss their involvement in osteogenic differentiation and osteoclastogenesis.
- To explore the potential of circRNAs as biomarkers for osteoporosis.
Main Methods:
- Literature review of recent studies on circRNAs and osteoporosis.
- Analysis of existing data on circRNA expression and function in bone cells.
- Evaluation of current evidence for circRNAs as diagnostic markers.
Main Results:
- CircRNAs exhibit cell and tissue-specific expression patterns.
- Recent evidence suggests circRNAs play regulatory roles in osteoblast and osteoclast differentiation.
- CircRNA signatures in blood, plasma, or serum show potential as osteoporosis biomarkers, requiring further validation.
Conclusions:
- CircRNAs are a promising class of regulatory molecules with significant implications for bone biology.
- Further research is needed to standardize methodologies and fully elucidate their roles in osteoporosis.
- CircRNAs hold potential for future therapeutic strategies and diagnostic applications in osteoporosis.

Osteoclasts in Bone Remodeling
3.1K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

The Nucleolus
8.9K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

Types of RNA
64.1K
Overview
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.

Transducer Mechanism: Nuclear Receptors
1.4K
Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Experimental RNAi
6.2K
RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...

siRNA - Small Interfering RNAs
16.9K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...
