Analysis of N6-Methyladenosine RNA Methylation Regulators in Diagnosis and Distinct Molecular Subtypes of Ankylosing...

Area of Science:

• Molecular Biology
• Immunology
• Genetics

Background:

• N6-methyladenosine (m6A) is a prevalent internal modification in eukaryotic mRNA.
• The role of m6A regulators in Ankylosing spondylitis (AS) remains largely unexplored.
• Understanding m6A regulation is crucial for advancing AS research.

Purpose of the Study:

• To identify and evaluate m6A regulators associated with Ankylosing spondylitis.
• To assess the predictive accuracy of m6A regulators for AS occurrence.
• To explore m6A patterns and their correlation with immune responses in AS patients.

Main Methods:

• Differentially Expressed Gene (DEG) analysis on the GSE73754 dataset comparing AS and non-AS patients.
• Random forest and nomogram models for screening candidate m6A regulators and assessing prediction accuracy.
• Principal Component Analysis (PCA) to calculate m6A scores and analyze m6A patterns in AS subgroups.

Main Results:

• Eight distinct m6A regulators were identified as significantly associated with AS.
• The developed models demonstrated predictive accuracy for AS occurrence.
• AS patients were classified into two subgroups based on m6A regulators, with Cluster A exhibiting activated CD4 and CD8 T cell immunity.

Conclusions:

• The identified m6A regulators play a significant role in the immune landscape of Ankylosing spondylitis.
• These findings provide a foundation for developing novel diagnostic biomarkers and therapeutic targets for AS.
• Further research into m6A patterns can enhance our understanding of AS pathogenesis and immunology.
