Decoding Non-Coding RNA Regulators in DITRA: From Genomic Insights to Potential Biomarkers and Therapeutic Targets.

Area of Science:

• Genetics and Molecular Biology
• Immunology
• Systems Biology

Background:

• Deficiency of IL-36 Receptor Antagonist (DITRA) is a rare monogenic autoinflammatory disease.
• DITRA is characterized by IL-36 signaling dysregulation and is a subtype of generalized pustular psoriasis.

Purpose of the Study:

• To investigate the role of coding and non-coding RNAs (ncRNAs) within the IL36RN interactome.
• To identify potential pathogenic mechanisms, biomarkers, and therapeutic targets for DITRA.

Main Methods:

• A systems biology approach utilizing the STRING database for protein-protein interaction network construction.
• Identification of ncRNA interactions via RNAInter and network analysis using Cytoscape.
• Pathway enrichment analysis to determine biological relevance of candidate ncRNAs and genes.

Main Results:

• Thirty-eight ncRNAs, including six lncRNAs and thirty-two miRNAs, were identified interacting with the IL36RN network.
• Thirty-three ncRNAs were linked to DITRA-related signaling pathways; seven protein-coding genes were highlighted, with TINCR, PLEKHA1, and HNF4A directly implicated.
• Many identified ncRNAs have prior associations with immune-mediated diseases like psoriasis, suggesting relevance in DITRA.

Conclusions:

• Novel insights into ncRNA-mediated regulation of IL36RN in DITRA were provided.
• Specific ncRNAs and genes (TINCR, PLEKHA1, HNF4A) show potential as key genomic elements for DITRA.
• Findings may inform biomarker discovery and targeted therapeutic development for DITRA.
