Project description:This SuperSeries is composed of the following subset Series: GSE31911: Cryptococcal H99 cells grown in 8 conditions for capsule induction GSE32049: RNA-Seq analysis of ada2?, nrg1? and cir1? and KN99? wildtype cells in capsule inducing and non-inducing conditions GSE32075: ChIP-Seq of H3K9 acetylation for wildtype and ada2? cells in Cryptococcus neoformans Refer to individual Series
Project description:SAGA member Ada2 is required for the majority of H3K9 acetylation in C. neoformans. To identify specific genomic loci that exhibit Ada2-dependent H3K9 acetylation, we performed ChIP-Seq against H3K9ac in wildtype and ada2Δ cells.
Project description:SAGA member Ada2 is required for the majority of H3K9 acetylation in C. neoformans. To identify specific genomic loci that exhibit Ada2-dependent H3K9 acetylation, we performed ChIP-Seq against H3K9ac in wildtype and ada2Δ cells. ChIP-Seq was performed using antibodies for H3K9ac in KN99 wildtype cells and ada2Δ cells. Input and IPed DNA was collected in triplicate from each strain and sequenced on an Illumnina HiSeq 2000 flow cell producing 84 million reads. Due to the lack of quality scores, raw reads are omitted from the submission.
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.
Project description:We investigated the effects of the hypoxia-mimetic CoCl2 on the gene expression of pathogenic fungus Cryptococcus neoformans. Keywords: compound treatment design
Project description:Lysine acetylation and ubiquitination are one of many protein modifications and play a crucial role in the biological regulation of many organisms, but little is known about the relationship between acetylation and ubiquitination few. Here, the Isw1 protein is an important member of the chromatin remodeling complex, and we performed single-protein modification mass spectrometry detection of the C. neoformans Isw1 protein and site mutations for both detected modifications. The data showed that the two modifications of Cryptococcus neoformans Isw1 protein have a balance of each other. Acetylation can maintain protein stability and maintain protein function, while ubiquitination can reduce protein level and maintain Isw1 protein expression. The expression level of Isw1 protein leads to resistance to antifungal drugs. These results reveal the resistance mechanism of Isw1 protein of Cryptococcus neoformans to antifungal drugs.
Project description:This study aimed to investigate transcriptomic changes in Cryptococcus neoformans mutants. We report transcriptome wide changes in the puf4∆ under basal growth conditions (30˚C, midlog, YPD). We report transcriptome remodeling following hydrogen peroxide (H2O2) treatment in wildtype (H99) and gcn4∆ cells.
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.
Project description:Mar1 deletion and RNA enrichment in Cryptococcus neoformans: pilot data for a high-throughput sequencing course. 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. 2. Which rRNA depletion method is best to use in the wetlab component of the course. This data was generated in preparation for the intensive summer course on high-throughput sequencing, funded by NIH grant 5R25EB023928-03 "A hands-on, integrative next-generation sequencing course: design, experiment, and analysis".
Project description:Invasive fungal infections (IFIs) are difficult to treat. Few effective antifungal drugs are available and many have problems with toxicity, efficacy and drug-resistance. To overcome these challenges, existing therapies may be enhanced using more than one agent acting in synergy. Previously, we have found amphotericin B (AMB) and the iron chelator, lactoferrin (LF), were synergistic against Cryptococcus neoformans and Saccharomyces cerevisiae. This study investigates the mechanism of AMB+LF synergy using RNA-seq in Cryptococcus neoformans H99.
