Streamlining differential exon and 3' UTR usage with diffUTR

Area of Science:

• Bioinformatics
• Computational Biology
• Genomics

Background:

• Alternative poly-adenylation and 3' UTR length are crucial for biological processes.
• Current transcriptomic data analysis methods have limitations in detecting 3' UTR changes.

Purpose of the Study:

• To introduce the diffUTR Bioconductor package for differential 3' UTR usage analysis.
• To improve upon and streamline differential exon usage (DEU) analyses.

Main Methods:

• Leveraging existing DEU tools and alternative poly-adenylation site databases.
• Developing the diffUTR Bioconductor package for enhanced analysis.

Main Results:

• diffUTR demonstrates greater flexibility and accuracy compared to current state-of-the-art methods.
• Validation performed through both simulations and real biological data.

Conclusions:

• diffUTR facilitates differential 3' UTR analysis.
• The package broadly supports DEU analysis and the exploration of associated results.
