Genome-wide analysis of alternative splicing associated with the transcription factor StuA in Trichophyton rubrum.

Loss of StuA in Trichophyton rubrum causes stage-specific alternative splicing changes in 104 genes linked to pathogenesis and keratin metabolism.

• Why it matters: Understanding how transcription factors like StuA regulate gene expression and splicing is crucial for revealing mechanisms of dermatophyte infection and potential therapeutic targets.
• What they did: Researchers analyzed RNA-sequencing data from wild-type and StuA-deficient strains grown in keratin medium, identifying differential alternative splicing events using the ASpli package, focusing on 104 genes.
• The result: Findings show StuA influences splicing of genes involved in carbohydrate processing, regulation, and transport, suggesting its key role in transcriptional and post-transcriptional control during infection-related growth.
