Map of dimorphic switching-related signaling pathways in Sporothrix schenckii based on its transcriptome
Sporotrichosis, an implantation mycosis caused by the dimorphic fungus Sporothrix schenckii, gained attention over the two last decades due to its broad geographic range and prevalence in tropical and subtropical areas. The dimorphic switching from hyphal form to the yeast form is essential for the pathogenesis of S. schenckii. During the mycelium-to-yeast transition, there are many changes in asexual development, yeast-phase cell formation, cell wall integrity, and melanin synthesis. However, the mechanisms of the signaling pathways associated with these process remain unclear. In this study, transcriptome sequencing of both the yeast stage and mycelium of S. schenckii was carried out. The results showed that 12217 genes, including genes involved in signal transduction and chitin synthesis, were expressed differentially between the two stages. According to these results, a map of the signaling pathways, related to the dimorphic switch, was drawn. Overall, the transcriptome data and analysis presented here lay the foundation for further research into the molecular mechanisms controlling the dimorphic switch of S. schenckii and support the development of anti-S. schenckii strategies targeting genes related to signaling pathways. Overall design: Examination of transcriptome of hyphal form and yeast form of S. schenckii.
