Air pollution and COPD: Unveiling the mechanisms through network toxicology and transcriptomics
Air pollution exposure is linked to Chronic Obstructive Pulmonary Disease (COPD) development. This study identifies HDAC9, DPP9, and KCNN4 as key gene targets potentially mediating this relationship, offering new insights into respiratory health.
Area of Science:
- Environmental Health
- Pulmonology
- Molecular Biology
Background:
- Air pollution poses a significant global health risk, especially to the respiratory system.
- Chronic Obstructive Pulmonary Disease (COPD) is a major public health concern with complex etiology.
- Understanding the molecular links between air pollutants and COPD is crucial for developing effective interventions.
Purpose of the Study:
- To investigate molecular mechanisms connecting air pollutant exposure and COPD development.
- To identify specific gene targets involved in air pollution-induced COPD.
- To provide a molecular basis for the adverse effects of air pollution on lung health.
Main Methods:
- Utilized public databases to identify genes associated with air pollutants and COPD.
- Performed Gene Ontology (GO) and KEGG pathway enrichment analyses.
- Cross-validated candidate genes using GEO datasets, molecular docking, and clinical data.
Main Results:
- Identified HDAC9, DPP9, and KCNN4 as candidate genes linking air pollutants to COPD.
- Molecular docking confirmed interactions between candidate targets and air pollutants.
- Validation through immune cell infiltration, single-cell transcriptomics, and risk models supported findings.
Conclusions:
- HDAC9, DPP9, and KCNN4 are implicated as key molecular players in COPD development due to air pollution.
- These findings enhance understanding of the molecular pathways affected by air pollution.
- Further research is warranted to explore therapeutic strategies targeting these genes.

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...
Chronic Obstructive Pulmonary Disease
Smoking is a primary risk factor for COPD, with over 80% of patients having a history of it. Patients typically experience progressive dyspnea or labored breathing, frequent coughing, and recurrent pulmonary infections. Many eventually succumb to respiratory failure, characterized by...
