(Submitter supplied) A family of APSES transcription factor is known to be fungal-specific transcriptional regulators and play important roles in governing growth, differentiation, and virulence of diverse fungal pathogens. Yet none of APSES-like transcription factors have been identified and investigated in a basidiomycetous fungal pathogen, Cryptococcus neoformans. In the present study we discovered an APSES-like transcription factor, Msa1 (Mbp1/Swi4-like APSES protein 1), as one of novel flucytosine-responsive genes (total 194 genes) identified through comparative transcriptome analysis of C. more...

(Submitter supplied) Cryptococcus neoformans (Cn) is an opportunistic fungal microorganism that causes life-threatening meningoencephalitis. During the infection, the microbial population is heterogeneously composed of cells with varying generational ages, with older cells accumulating during chronic infections. This is attributed to their enhanced resistance to phagocytic killing and tolerance of antifungals like fluconazole (FLC). more...

(Submitter supplied) Fluconazole (FLC), a triazole antifungal drug, is widely used for the maintenance therapy of cryptococcal meningoencephalitis, the most common opportunistic infection in AIDS patients, but this usage predisposes to the appearance of FLC resistance, especially in patients with no or limited access to highly active antiretroviral therapy. We used microarray analysis to examine changes in the gene expression profile of C. more...

(Submitter supplied) In the pathogenic yeast Candida albicans, the zinc cluster transcription factor Upc2p has been shown to regulate expression of ERG11 and other genes involved in ergosterol biosynthesis upon exposure to azole antifungals. ERG11 encodes lanosterol demethylase, the target enzyme of this antifungal class. Over-expression of UPC2 reduces azole susceptibility, whereas its disruption results in hypersusceptibility to azoles and reduced accumulation of exogenous sterols. more...

(Submitter supplied) The cAMP-pathway plays a central role in regulation of growth, differentiation, and virulence of human pathogenic fungi, including Cryptococcus neoformans. Three major upstream signaling regulators of the adenylyl cyclase (Cac1), Ras, Aca1 (Adenylyl cyclase-associated protein 1) and G-alpha subunit protein (Gpa1), have been identified to control the cAMP-pathway in C. neoformans, but their functional relationship remains elusive. more...

(Submitter supplied) This set of experiment was done in order to analyze the effect of a dysfunctional mitochondria on C. albicans. The mutant was obtained by deleting the gene FZO1, which is known to be involved in mitochondrial biogenesis in S. cerevisiae. We show that the deletion of FZO1 leads to a change in mitochondrial morphology, which affects the mitochondrial membrane potential and causes the loss of mtDNA. Upon performing a transcriptome analysis, we observed that the mutant showed upregulation of genes like AOX2, MDR1 etc., while the genes involved in iron uptake were dysregulated. more...

(Submitter supplied) We characterized the impact of the J domain co-chaperone, Dnj4, on the transcriptional response to DNA damage induced by hydroxyurea (an inhibitor of ribonucleotide reductase) in Cryptococcus neoformans. We treated wild type (WT) and mutant dnj4∆ log phase cells with hydroxyurea for one hour and found that the loss of DNJ4 impaired the transcriptional response to HU. In particular, the up-regulation of DNA damage and repair genes as well as iron uptake genes was impaired in these mutants. more...

The sequence reads that passed quality filters were analyzed at the transcript isoform level. qRT–PCR validation was performed using SYBR Green assay. We find that genes invovled in mitochondrial respiration such as NUO1, NUO2 and MCI4 and ribosomal biogenesis such as RPL5,RPS43,RPS12 were downregulated. more...

(Submitter supplied) Eupolauridine and liriodenine are plant-derived aporphinoid alkaloids that exhibit potent inhibitory activity against the opportunistic fungal pathogens Candida albicans and Cryptococcus neoformans. However, the molecular mechanism of this antifungal activity is unknown. In this study, we show that eupolauridine 9591 (E9591), a synthetic analog of eupolauridine, and liriodenine methiodide (LMT), a methiodide salt of liriodenine, mediate their antifungal activities by disrupting mitochondrial iron-sulfur (Fe-S) cluster synthesis. more...

The goal of this project was to generate pilot data in preparation for a summer course on high-throughput sequencing where participants prepared their own RNA-Seq libraries and analyzed the resulting data. This pilot experiment addressed two questions: 1. Does this experimental system (Cryptococcus neoformans H99 wildtype and mar1 deletion mutant grown in YPD and tissue culture media) provide a good dataset for course participants to analyze. more...
