Aspergillus CEA10 compared to SRBA mutant under hypoxic conditions


ABSTRACT: Aspergillus fumigatus strains CEA10 and srbA mutant expression patterns were compared after exposure to 24h of hypoxic conditions Goal of this study was to find genes that are directly and/or indirectly regulated by the transcription factor srbA, that is know to be crucial for growth under hypoxic conditions Keywords: hypoxic stress response two strains, 2 biological replicates with dye-swaps

ORGANISM(S): Aspergillus fumigatus

At the site of microbial infections, the significant influx of immune effector cells and the necrosis of tissue by the invading pathogen generate hypoxic microenvironments in which both the pathogen and host cells must survive. Currently, whether hypoxia adaptation is an important virulence attribute of opportunistic pathogenic molds is unknown. Here we report the characterization of a sterol-regulatory element binding protein, SrbA, in the opportunistic pathogenic mold, Aspergillus fumigatus. L  ...[more]
