Sequence Alignment between TRIM33 Gene and Human Noncoding RNAs: A Potential Explanation for Paraneoplastic
1Rheumatology Unit, Department of Clinical and Experimental Medicine, University Hospital "Gaetano Martino", 98124 Messina, Italy.
Background:
This computational analysis investigated sequence complementarities between the TRIM33 gene and human noncoding (nc)RNAs and characterized their interactions in the context of paraneoplastic dermatomyositis.
Methods:
TRIM33 FASTA sequence (NCBI Reference Sequence: NC_000001.11) was used for BLASTN analysis against Human GRCh38 in the Ensembl.org database. Retrieved ncRNAs showing hits to TRIM33 were searched in the GeneCards.org database and further analyzed through RNAInter, QmRLFS-finder, Spliceator, and NcPath enrichment analysis.
Results:
A total of 100 hits were found, involving the lncRNAs NNT-AS1, MKLN1-AS, LINC01206, and PAXBP1-AS1, whose dysregulation has been reported in either cancer or dermatomyositis. Additionally, the lncRNAs NNT-AS1 and PAXBP1-AS1 may interact with microRNA-142-3p, reducing its expression and increasing that of TRIM33. Sequence complementarity affected only TRIM33 intron 1, possibly resulting in alternatively spliced isoforms of TIF1γ with increased immunogenicity. The results also revealed nucleotide alignment between TRIM33 and the gene regulatory elements of 28 ncRNA genes involved in immune pathways.
Conclusions:
This pivotal study demonstrates sequence complementarity between TRIM33 and human ncRNAs dysregulated in cancer and dermatomyositis. This scenario may lead to the overproduction of more immunogenic TIF1γ variants in tumors and the stimulation of autoimmunity. Further experimental analyses using targeted methods such as Western blot or Chip-Seq are required to confirm these data.
Insights
This study found sequence complementarity between TRIM33 and noncoding RNAs in paraneoplastic dermatomyositis. This interaction may increase immunogenic TIF1γ variants, potentially driving autoimmunity and cancer progression.
Area of Science:
- Genetics
- Molecular Biology
- Immunology
Background:
- Investigates sequence complementarity between the TRIM33 gene and human noncoding RNAs (ncRNAs).
- Examines these interactions within the context of paraneoplastic dermatomyositis.
- Focuses on computational analysis to identify potential regulatory mechanisms.
Purpose of the Study:
- To computationally identify and characterize sequence complementarities between TRIM33 and human ncRNAs.
- To understand the role of these interactions in paraneoplastic dermatomyositis.
- To explore potential implications in cancer and autoimmune disease.
Main Methods:
- Utilized BLASTN analysis of TRIM33 FASTA sequence against the Human GRCh38 database.
- Analyzed retrieved ncRNAs using RNAInter, QmRLFS-finder, Spliceator, and NcPath.
- Cross-referenced findings with Ensembl.org and GeneCards.org databases.
Main Results:
- Identified 100 hits, including lncRNAs NNT-AS1, MKLN1-AS, LINC01206, and PAXBP1-AS1, previously linked to cancer or dermatomyositis.
- Found potential interaction between NNT-AS1/PAXBP1-AS1 and microRNA-142-3p, affecting TRIM33 expression.
- Revealed sequence complementarity in TRIM33 intron 1, potentially creating immunogenic TIF1γ isoforms and identifying 28 immune-related ncRNA gene regulatory elements.
Conclusions:
- Demonstrates sequence complementarity between TRIM33 and ncRNAs implicated in cancer and dermatomyositis.
- Suggests this interaction may cause overproduction of immunogenic TIF1γ variants, contributing to tumors and autoimmunity.
- Recommends further experimental validation using methods like Western blot or Chip-Seq.
