Effect of Artemisinin on Aspergillus fumigatus gene expression program

Project description:We examined the antifungal activity of artemisinin against Aspergillus fumigatus (A. fumigatus), a pathogenic filamentous fungus responsible for allergic and invasive aspergillosis in humans and analyzed transcript profiles of the fungus on exposure to Artemisinin. A. fumigatus spores were cultured for 48 h and then treated with artemisinin (at MIC50 concentration) or solvent control (DMSO) for 3 h to study its transcriptomic profiles.

Transcriptomics analysis of Aspergillus fumigatus co-cultivated with Pseudomonas aeruginosa

Project description:We report a study conducted to investigate the variation on gene expression of the pathogenic fungus Aspergillus fumigatus upon co-cultivation with the pathogenic bacterium Pseudomonas aeruginosa. The study was conducted by investigating the gene expression variation at different time points (45, 90 and 180 minutes after co-incubation). As control, we used data obtained by cultivating the fungus either without bacteria, or with heat-inactivated Pseudomonas.

Heterogeneity in the transcriptional response of the human pathogen Aspergillus fumigatus to the antifungal agent caspofungin

Project description:The transcription factor CrzA influences cell wall organization in the pathogenic fungus Aspergillus fumigatus, and also binds to the promoter regions of chitin synthase genes upon exposure to the antifungal drug caspofungin. To gain an overview of the genes directly regulated by CrzA, the CrzA binding sites were determined genome-wide by ChIP-seq

Transcriptome response of Aspergillus fumigatus cultures under different temperatures

Project description:Microarray analysis was used to compare gene expression of Aspergillus fumigatus under two different sporulation temperatures, 17oC and 32oC, with an emphasis on genes encoding known or putative allergens of the fungus. The objective of the study was to investigate whether allergenic potencies of A. fumigatus spores produced under different sporulation temperatures would be influenced by temperature-dependent transcriptional regulation of allergenicity genes.

Next Generation Sequencing identifies O2-responsive genes in the human pathogenic fungus Aspergillus fumigatus

Project description:Low oxygen conditions are not only common to natural environments but also occur during tissue invasive growth in the human host. Only few cellular factors have been identified up to now that allow the fungus to efficiently adapt its energy metabolism to the lack of O2. In the present study, we cultivated A. fumigatus in an O2-controlled fermenter and analysed its minute-scale responses to O2 limitation. Transcriptome sequencing revealed a group of genes underlying a rapid and highly dynamic regulation. As an initial experimental setup, A. fumigatus was cultivated in an O2-controlled fermenter, which allowed minute-scale variations in O2-fluxes largely independent of other secondary effects. Cultures were initially grown at saturated O2 concentrations (100% saturation ≈ 260 µmol l-1) and rapidly shifted to hypoxic growth conditions at an initial O2 saturation of 5% (≈ 13 µmol l-1).

Transcriptome study of A. fumigatus hyphae and human neutrophils

Project description:The infections with the human pathogenic fungus A. fumigatus is an emerging problem. The infections process and the reaction of the immune systeme to the infection is still not complete understood. So we analyzed the response of A. fumigatus to human neutrophils to get insights of these interaction.
