Project description:The leucine CUG codon was reassigned to serine in the fungal pathogen Candida albicans. To clarify the biological role of this tuneable codon ambiguity on drug resistance, we evolved C. albicans strains that were engineered to mistranslate the CUG codon at constitutively elevated levels, in the presence and absence of the antifungal drug fluconazole. Elevated levels of mistranslation resulted in the rapid acquisition of resistance to fluconazole.
Project description:Aneuploidy and the evolution of aneuploid karyotypes of Candida albicans strains was identified using aCGH. Whole chromosome and segmental aneuploidies, (specifically on the left arm of chromosome 5 - shown to be due to isochromosome formation) are associated with the appearance of resistance to the antifungal drug fluconazole. Keywords: Comparative Genomic Hybridization

Keywords: Comparative Genomic Hybridization Hybridization of all strains was compared to the hybridization of SC5314, the sequenced laboratory strain.
Project description:The Neosartorya (Aspergillus) fischeri antifungal protein 2 (NFAP2) represents a particularly promising candidate in the fight against fungal infections. To facilitate the progression of NFAP2 toward clinical application, a comprehensive understanding of its antifungal mode of action against filamentous Candida forms is essential. In the present study, we analyzed the transcriptomic responses of filamentous Candida albicans and pseudohyphal Candidozyma (Candida) auris cells following exposure to NFAP2.
Project description:Natural product cinnamaldehyde has significant antifungal activities, and its inhibitory activity against Candida albicans has been reported. Up to now, there are few reports on the changes in the transcriptome of Candida albicans after cinnamaldehyde treatment. Here, RNA sequencing analysis of samples obtained from Candida albicans cells grown in the presence or absence of cinnamaldehyde was performed. A total of 123 differentially expressed genes were identified, of which 15 genes were up-regulated and 108 genes were down-regulated.
