Transcriptome analysis of the Aspergillus fumigatus calcineurin

Project description:Calcineurin plays an important role in the control of cell morphology and virulence in fungi. Calcineurin is a serine/threonine-specific protein phosphatase heterodimer consisting of a catalytic subunit A and a regulatory Ca2+/Calmodulin binding subunit. A mutant of A. fumigatus lacking the calcineurin A (calA) catalytic subunit exhibited defective hyphal morphology related to apical extension and branching growth, which resulted in drastically decreased filamentation. Here, we investigated which pathways are influenced by A. fumigatus calcineurin during proliferation by comparatively determining the transcriptional profile of A. fumigatus wild type and delta calA mutant strains. Our results showed that although the mitochondrial function is reduced in the delta calA mutant strain, its respiratory chain is functional and the mutant has increased alternative oxidase (aoxA) mRNA accumulation and activity. Furthermore, we identified several genes that encode transcription factors that have increased mRNA expression in the delta calA mutant and that could be involved in the Cal-CrzA pathway. Deletion mutants for these transcription factors had also reduced susceptibility to itraconazole, caspofungin, and sodium dodcyl sulfate.

Transcription profiling of Aspergillus fumigatus Af293 after temperature shifting

Project description:Experimental factor: Time after the temperature shift from 30C to 37C or 30C to 48C. Conidia (5x106 /ml) from Aspergillus fumigatus Af293 were incubated in the CM medium for germination (~ 17 hrs) at 30C. The culture was transferred to a water bath of 37C or 48C for continued growth. Samples were taken after the defined time (i.e. 0, 15, 30, 60, 120, and 180 min.).

Stress responses elicited by glucose withdrawal in Aspergillus fumigatus

Project description:Glucose is a widely used carbon source in laboratory practice to culture Aspergillus fumigatus, however, glucose availability is often low in its “natural habitats” including the human body. We used a physiological–transcriptomical approach to reveal differences between A. fumigatus Af293 cultures incubated on glucose, glucose and peptone, peptone (carbon limitation), or without any carbon source (carbon starvation). Autolytic cell wall degradation was upregulated by both carbon starvation and limitation. The importance of autolytic cell wall degradation in adaptation to carbon stress was also highlighted by approximately 12.4% of the A. fumigatus genomes harbor duplication of genes involved in N-acetyl glucosamine utilization. Glucose withdrawal increased redox imbalance, altered both the transcription of antioxidative enzyme genes and oxidative stress tolerance, downregulated iron acquisition, but upregulated heme protein genes. Transcriptional activity of the Gliotoxin cluster was low in all experiments, while the Fumagillin cluster showed substantial activity both on glucose and under carbon starvation, and the Hexadehydro-astechrome cluster only on glucose. We concluded that glucose withdrawal substantially modified the physiology of A. fumigatus including processes that contribute to virulence. This may explain the challenge of predicting the in vivo behavior of A. fumigatus based on data from glucose rich cultures.
