Abstract:
Globally, osteoporosis is the most common systemic skeletal disease. There are many factors that influence osteoporosis' development and progression. During the pathogenesis of this disease, bone turnover is imbalanced between resorption and the formation of bone tissue. A growing interest has been devoted to the role that microRNA (miRNA) plays in osteoporosis regulation. A microRNA (miRNA) is a group of small single-stranded RNA molecules involved in regulating gene expression in eukaryotic organisms. As microRNAs (miRNAs) are key regulators of gene expression and can modulate processes related to bone metabolism, they have become increasingly important for studying osteoporosis pathogenesis. The available research suggests that miRNAs play an important role in regulating processes associated with bone metabolism, especially by influencing bone resorption and synthesis. Furthermore, microRNAs can also serve as potential therapeutic targets for osteoporosis, besides being a rapid and specific biomarker.
Insights
MicroRNAs (miRNAs) are small RNA molecules crucial for regulating gene expression. Research highlights their significant role in bone metabolism, impacting osteoporosis development and progression.
Area of Science:
- Biochemistry
- Molecular Biology
- Genetics
Background:
- Osteoporosis is a prevalent systemic skeletal disease characterized by imbalanced bone turnover.
- MicroRNAs (miRNAs) are small, non-coding RNA molecules that regulate gene expression in eukaryotes.
- Emerging research indicates miRNAs are key regulators of cellular processes, including bone metabolism.
Purpose of the Study:
- To explore the regulatory role of microRNAs (miRNAs) in the pathogenesis of osteoporosis.
- To investigate the influence of miRNAs on bone resorption and synthesis processes.
- To assess the potential of miRNAs as biomarkers and therapeutic targets for osteoporosis.
Main Methods:
- Literature review of studies investigating miRNA involvement in bone metabolism.
- Analysis of research on miRNA-mediated regulation of osteoblast and osteoclast activity.
- Examination of data on miRNA expression patterns in osteoporosis models and patients.
Main Results:
- MicroRNAs significantly influence bone turnover by modulating both bone resorption and formation.
- Specific miRNAs have been identified as critical regulators in pathways affecting skeletal homeostasis.
- Dysregulation of certain miRNAs is associated with the development and progression of osteoporosis.
Conclusions:
- MicroRNAs are pivotal in regulating bone metabolism and are implicated in osteoporosis pathogenesis.
- miRNAs hold promise as sensitive biomarkers for early osteoporosis detection.
- Targeting specific miRNAs presents a potential novel therapeutic strategy for managing osteoporosis.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

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...
