Functional characterization of SHC-like triterpene cyclase genes in azole response and virulence-related traits of Aspergillus fumigatus.
Deletion of shc1 in Aspergillus fumigatus increases resistance to azole antifungals and reduces virulence, highlighting its role in drug response and pathogenicity.
- Why it matters: Understanding the genetic factors behind azole resistance and virulence is crucial for improving treatment strategies against this opportunistic pathogen, especially as resistance rises.
- What they did: Researchers used gene deletion, phenotypic assays, transcriptomics, and metabolite profiling on three SHC-like triterpene cyclase genes, revealing functional divergence and links to membrane properties and drug susceptibility.
- The result: Findings suggest shc1 influences azole resistance and virulence traits, providing potential targets for overcoming drug resistance and mitigating infection severity in clinical settings.
