Transcriptomes of Aspergillus fumigatus Z5 induced by different carbon sources

Project description:Various saprotrophic microorganisms, especially filamentous fungi, can efficiently degrade lignocellulose that is one of the most abundant natural material on earth. It consists of complex carbohydrates and aromatic polymers found in plant cell wall and thus in plant debris. Aspergillus fumigatus Z5 was isolated from compost heaps and showed highly efficient plant biomass-degradation capability.Genome analysis revealed an impressive array of genes encoding cellulases, hemicellulases, and pectinases involved in lignocellulosic biomass degradation. We sequenced the transcriptomes of Aspergillus fumigatus Z5 induced by sucrose, xylan, cellulose and rice straw, respectively. There were 444, 1711 and 1386 significantly differently (q-value â¤ 0.0001 and |log2 of the ratio of the RPM values| â¥ 2) expressed genes in xylan, cellulose and rice straw,respectively, relative to sucrose control. After incubation at 45 â, 145rpm for 20 hours with sucrose as the carbon source, mycelia were induced for 16 hours using xylan, cellulose and rice straw, respectively. Transcriptome induced by sucrose was used as the control when comparing the differences between other three transcriptomes (induced by xylan, cellulose and rice straw, respectively).

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.

Monitoring the mating-type-driven transcriptomes of Aspergillus fumigatus

Project description:Sexual identity of the human pathogenic mold Aspergillus fumigatus is determined by the mating-type idiomorphs MAT1-1 and MAT1-2 residing at the MAT locus. Given that the MAT1 gene products are DNA binding master regulators that govern fruiting body formation, the MAT1-driven transcriptomes of A. fumigatus were monitored by conditional overexpression of either MAT1 gene followed by RNA-seq analyses.

Next Generation Sequencing of HUVECs stimulated by conidia of Aspergillus fumigatus

Project description:Purpose: The goal of this study is to investigate the responses of HUVECs after the stimulation of conidia of A. fumigatus Methods: HUVECs were stimulated with conidia of Aspergillus fumigatus for 2 and 6 hours. Three biological repeats of stimulated cells or un-stimulated controls were send for RNA sequencing. Results: Using an optimized data analysis workflow, we mapped about 40 million sequence reads per sample to the human genome (build hg38) and identified round 80,000 transcripts in the HUVECs upon stimulation. Conclusions: Our resutls showed the detailed analysis of HUVECs transcriptomes upton conidia of Aspergillus fumigatus stimulation.

Effect of amphotericin B on Aspergillus fumigatus

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
