Insights
This study reveals that TRPV1 (transient receptor potential vanilloid 1) and specific cytokines are key factors in pediatric asthma development. Elevated TRPV1 mRNA and certain cytokine levels indicate increased risk for childhood asthma.
Area of Science:
- Molecular Biology
- Immunology
- Pediatrics
Background:
- Pediatric bronchial asthma is a complex respiratory condition with incompletely understood regulatory mechanisms.
- The transient receptor potential vanilloid 1 (TRPV1) channel and associated cytokines are implicated in inflammatory processes.
- Investigating their role in childhood asthma is crucial for understanding pathogenesis.
Purpose of the Study:
- To elucidate the regulatory mechanisms of TRPV1 and related cytokines in pediatric bronchial asthma.
- To identify potential risk factors and establish a preliminary regulatory network for childhood asthma.
Main Methods:
- Real-time quantitative PCR to assess TRPV1 mRNA levels and single nucleotide polymorphism (SNP) genotypes.
- Western blot and ELISA to quantify cytokine levels (e.g., IgE, IL-2, IL-4, IL-5, EOS).
- Logistic regression, KEGG analysis, and bioinformatics tools for correlation analysis and tertiary protein structure/miRNA binding site prediction.
Main Results:
- Significant differences in TRPV1 mRNA levels, SNP genotype distribution, and cytokine profiles were observed between pediatric asthma cases and controls.
- Logistic regression identified TRPV1 mRNA levels, EOS, IL-4, and IL-5 as potential risk factors for childhood asthma.
- Mutations in TRPV1 gene SNPs (rs4790521, rs4790522) altered miRNA binding sites.
Conclusions:
- A preliminary regulatory network involving TRPV1 and related cytokines in pediatric bronchial asthma has been established.
- These findings provide a theoretical basis for understanding the pathogenesis and developing therapeutic strategies for childhood asthma.
Abstract:
Our purpose was to investigate the regulatory mechanism of TRPV1 and related cytokines on children bronchial asthma. TRPV1 mRNA level and two SNP genotypes of children in case group and control group were detected by real-time quantitative PCR. Western blot and ELISA were used to measure the levels of cytokines like IgE, IL-2, etc. Their correlations were analyzed by Logistic regression and KEGG analysis. Moreover, tertiary structure of protein and miRNA binding sites were also predicted by online tools. Case group was obviously different from control group in TRPV1 mRNA level, the two SNP genotypes distribution and the related cytokines levels. Logistic regression analysis further demonstrated that TRPV1 mRNA level, EOS, IL-4 and IL-5 may be risk factors for children bronchial asthma. And based on that, the preliminary regulatory network of children bronchial asthma was drawn. What's more, mutation of rs4790521 and rs4790522 in TRPV1 gene both induced its corresponding miRNA binding site's change. The preliminary regulatory network of TRPV1 and related cytokines on children bronchial asthma established in this study provides certain theoretical basis for pathogenesis and treatment of children bronchial asthma.
