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
Project description:Based on epidemiological studies, Aspergillus candidus has been demonstrated as an emerging fungal agent of toenail onychomycosis. Here we report a case of a toenail infection caused by A. candidus in a healthy 60-year-old woman. Based on macroscopic and microscopic characteristics of the culture as well as nucleotide sequencing of 28S region, the causative agent was identified as A. candidus.
Project description:Three new p-terphenyl derivatives, named 4″-O-methyl-prenylterphenyllin B (1) and phenylcandilide A and B (17 and 18), and three new indole-diterpene alkaloids, asperindoles E-G (22-24), were isolated together with eighteen known analogues from the fungi Aspergillus candidus associated with the South China Sea gorgonian Junceela fragillis. The structures and absolute configurations of the new compounds were elucidated on the basis of spectroscopic analysis, and DFT/NMR and TDDFT/ECD calculations. In a primary cultured cortical neuronal network, the compounds 6, 9, 14, 17, 18 and 24 modulated spontaneous Ca2+ oscillations and 4-aminopyridine hyperexcited neuronal activity. A preliminary structure-activity relationship was discussed.
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: GSE9275: A tri-species Aspergillus array (nidulans arrays) GSE9276: A tri-species Aspergillus array (niger arrays) GSE9277: A tri-species Aspergillus array (oryzae arrays) Keywords: SuperSeries Refer to individual Series
