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.
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. Non-sporulating liquid culture of Aspergillus fumigatus was harvested and divided equally onto two sets of potato dextrose agar plates, one set for incubation at 17oC, the other for incubation at 32oC. After 48 hours of incubation, RNA was harvested from both sets of sporulating cultures, reverse-transcribed into dye-coupled cDNA and hybridized onto microarrays for analysis of gene expression. For each experiment, extracted RNA from the two cultures were hybridized onto two dye-swap technical replicate arrays. A total of three separate experiments were conducted for biological triplicates, for a total of six hybridizations.
Project description:Genomic DNA from five strains, Aspergillus fumigatus Af71, Aspergillus fumigatus Af294, Aspergillus clavatus, Neosartorya fenneliae, and Neosartorya fischeri, were co-hybridized with that of Aspergillus fumigatus Af293 and compared.
Project description:This SuperSeries is composed of the following subset Series: GSE24983: Response of A549 cells treated with Aspergillus fumigatus [WT-CF_vs_WT-GC] GSE24984: Response of A549 cells treated with Aspergillus fumigatus [WT-GC_vs_PrtT-GC] GSE24985: Response of A549 cells treated with Aspergillus fumigatus [WT-CF_vs_PrtT-CF] Refer to individual Series
Project description:Human dendritic cells were coinfected with Aspergillus fumigatus and human cytomegalovirus. Single-cultures or single-infections served as controls. RNA was isolated and processed for next generation sequencing.
Project description:Amphotericin B (AMB) is the most widely used polyene antifungal drug for the treatment of systemic fungal infections including invasive aspergillosis. We aimed to understand molecular targets of AMB in Aspergillus fumigatus (Afu) by genomic approaches. Keywords: Aspergillus fumigatus treated with amphotericin B for 24 hours
Project description:We report gene expression differences in Aspergillus fumigatus wild type, hrmA mutant, and overexpression under hypoxia and normoxia conditions
