Project description:Transcriptome profiling of wild type and cfo1 mutant with fluconazole treatment in Cryptococcus neoformans var. grubii H99 Purpose: The goals of this study are to compare cfo1 mutant transcriptome profiling (RNA-seq) to wild-type with or without fluconazole treatment in Cryptococcus neoformans var. grubii H99. Methods: mRNA profiles of wild-type and cfo1 mutant with or without fluconazole treatment were generated by RNA-Seq, using Illumina GAIIx. The sequence reads that passed quality filters were mapped to reference genome and the normalized RPKM values were calculated by CLC Genomics Workbench. Results: Compared to wild-type, a number of genes were differentially expressed in the cfo1 mutant, especially genes involved in iron homeostasis and transport, ergosterol biosynthesis, mitochondrial function and respiration. Conclusions: Our data suggested reduced expression of the genes in the respiratory chain is the main reason for altered antifungal sensitivity of the cfo1 mutant. The results of our study revealed that iron uptake plays a key role in fluconazole sensitivity of C. neoformans.
Project description:Cell-cycle transcript dynamics from two species of wild-type budding yeast growing at 30 degrees Celsius in rich media: Saccharomyces cerevisiae (BF264-15D background) and Cryptococcus neoformans var. grubii (H99F background). We compared programs of cell-cycle-regulated genes between distantly related budding yeasts.
