Abstract:
Chronic obstructive pulmonary disease (COPD) is a progressive lung disease and is currently the fourth leading cause of death worldwide. Chronic inflammation and repair processes in the small airways are characteristic of COPD. Despite extensive efforts from researchers and industry, there is still no cure for COPD, hence an urgent need for new therapeutic alternatives. MicroRNAs are such an option; they are small noncoding RNAs involved in gene regulation. Their importance has been shown with respect to maintaining the balance between health and disease. Although previous reviews have discussed the expression of microRNAs related to lung disease, a detailed discussion regarding the function of differential miRNA expression in the pathogenesis of COPD is lacking.In this review we link the expression of microRNAs to different features of COPD and explain their importance in the pathogenesis of this disease. We further discuss their potential to contribute to the development of future therapeutic strategies.
Insights
Chronic obstructive pulmonary disease (COPD) is a leading cause of death. This review explores how microRNAs (a type of gene regulator) are involved in COPD development and could offer new therapeutic strategies.
Area of Science:
- Pulmonary Medicine
- Molecular Biology
- Genetics
Background:
- Chronic obstructive pulmonary disease (COPD) is a progressive, fatal lung disease characterized by chronic inflammation.
- Current treatments for COPD are limited, highlighting the need for novel therapeutic approaches.
- MicroRNAs (miRNAs) are small noncoding RNAs crucial for gene regulation and maintaining cellular homeostasis.
Purpose of the Study:
- To review the role of differential microRNA expression in the pathogenesis of COPD.
- To connect specific miRNA expression patterns to distinct features of COPD.
- To explore the therapeutic potential of miRNAs for COPD treatment.
Main Methods:
- Literature review focusing on studies investigating miRNA expression in COPD.
- Analysis of existing research linking miRNA function to COPD pathogenesis.
- Synthesis of information on miRNA-based therapeutic strategies for COPD.
Main Results:
- MicroRNA dysregulation is implicated in the chronic inflammation and repair processes characteristic of COPD.
- Specific miRNAs are associated with key pathological features of COPD, influencing disease progression.
- Altering miRNA expression presents a promising avenue for developing new COPD therapies.
Conclusions:
- MicroRNAs play a significant role in the pathogenesis of COPD.
- Targeting miRNAs offers a potential strategy for future COPD therapeutic interventions.
- Further research into miRNA function can advance COPD treatment options.

The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
