ECgene provides functional annotation for alternatively spliced genes across nine organisms. New tools analyze differential gene expression at multiple levels, improving functional and expression analysis for researchers.

Area of Science:

  • Genomics
  • Bioinformatics
  • Molecular Biology

Background:

  • Alternative splicing (AS) significantly increases proteomic diversity.
  • Functional annotation and expression analysis of alternatively spliced genes are crucial for understanding biological complexity.
  • Existing databases often lack comprehensive AS modeling and differential expression analysis capabilities.

Purpose of the Study:

  • To expand ECgene's capabilities for genome-based transcript modeling of alternative splicing (AS).
  • To enhance functional annotation and expression analysis of alternatively spliced genes.
  • To introduce new tools for differential expression analysis at gene, isoform, and exon levels.

Main Methods:

  • Genome-based transcript modeling for AS.

  • Expansion of AS modeling and EST clustering to nine organisms.

    • Main Results:

    • ECgene now supports AS modeling and EST clustering for nine organisms.
    • New applications, ECprofiler and DEGEST, facilitate ontology-based gene search and differential expression analysis.
    • Gene expression analysis is performed at gene, isoform, and exon levels.
    • ASviewer provides visualization of transcript structures and functional features.
    • Enhanced user interfaces improve functional and expression data exploration.

    Conclusions:

    • ECgene offers a comprehensive platform for functional annotation and expression analysis of alternatively spliced genes.
    • The expanded multi-organism support and advanced analysis tools enhance its utility for genomic research.
    • ECgene facilitates deeper understanding of gene expression regulation and functional diversity arising from alternative splicing.
