Transcriptomic response of Cryptococcus neoformans to ecologically relevant nitrogen concentrations

ABSTRACT: We examine the transcriptomic response of Cryptococcus neoformans to two different ecologically relevant nitrogen concentrations. Our data revealed that low nitrogen conditions modulate the expression of numerous virulence genes in C. neoformans. Among these were, CTR4 and CGP1, which showed highly significant modulation under low nitrogen conditions. Furthermore, data analysis revealed the upregulation of antifungal tolerance-related genes in low nitrogen conditions, including genes involved in ergosterol biosynthetic processes and cell wall integrity. Overall, our findings provide insight into the survival of C. neoformans in nitrogen-poor ecological niches and suggest that pre-adaptation to these conditions may influence the pathobiology of this yeast.

Ribosome profiling of Cryptococcus neoformans H99

Project description:We measured protein translation (by ribosome profiling) and RNA levels (by polyA-enriched RNA-seq) in Cryptococcus neoformans strain H99 and Cryptococcus neoformans strain JEC21. This is the first transcriptome-wide map of translation in this species complex.

A defect in iron uptake enhances the susceptibility of Cryptococcus neoformans to azole antifungal drugs.

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.

Comparative Analysis of Antifungal Mechanism of Lauryl betaine in the Human Fungal Pathogens Cryptococcus neoformans and Malassezia restricta

Project description:Purpose: Understanding the mechanism of action of lauryl betaine against Cryptococcus neoformans and Malassezia restricta. Methods: The transcriptome profile of the lauryl betaine-treated cells compared to that of untreated cells were generated by RNA-seq Illumina Hiseq. Results: A number of genes were differentially expressed in the lauryl betaine-treated cells, which include genes involved in ergosterol biosynthetic pathway.

Genome-wide analysis of a transcriptional network of the Sterol Regulatory Element Binding Protein, Sre1, in the human fungal pathogen Cryptococcus neoformans (RNA-seq)

Project description:Purpose: Understanding the regulatory role of Sre1 in Cryptococcus neoformans. Methods: The transcriptome profiles of the wild-type and sre1 mutant were generated by RNA-seq using Illumina Hiseq. The transcriptome profile of the sre1 mutant was compared with that of the wild-type strain. Results: The Sterol Regulatory Element Binding Protein, Sre1 is a major regulator for the genes involved in ergosterol biosynthetic pathway and iron acquisition in C. neoformans.

Cryptococcus neoformans proteins during fungal-macrophage interaction

Project description:Cryptococcus neoformans interactions with murine macrophages are critical for disease. In this project we analyzed fungal proteins which were co-purified with murine host proteins after interaction. H99 C. neoformans was opsonized with mAb 18B7 and addedd to murine macrophages. Then murine cells were lysed and cell extracts submitted to proteomics.
