Candida albicans exhibits distinct cytoprotective responses to anti-fungal drugs

ABSTRACT: We transcriptionally profiled thousands of C. albicans untreated and drug-treated cells at early and late timepoints by modifieying a single cell platform for fungal setting. Our DROP-seq set up was able to capture transcriptional signals in ~20K C. albicans . We were able to show cell-cell heterogeneity in seemingly isogenic populations of C. albicans untreated cells that coupled with cell cycle checkpoints. We also observed that individuals treating with different anti-fungals were partitioned into 20 subpopulations. The data shows a bifurcation into two major responses, term and responses, two days post-treatment. A transition from response to response was observed at day 3 which stay consistent to day 6. Bulk DNA sequencing does not show genomic abberation to be related to either or responses and the resistance does not change from day two to day six in diffusion disk assay. This can be an evidence of selection for cells that are able to mount an efficient tolerance response to anti-fungals early post treatment.Targeting cells, or genes and pathways that support the to transition are interesting avenues to block drug tolerance.

Gene expression profiles of human immature dendritic cells after 12h of co-cultivation with Aspergillus fumigatus, Candida albicans and LPS

Project description:In a whole-transcriptome study, cellular responses of DCs confronted with the fungi A. fumigatus, C. albicans or the bacterial cell wall component lipopolysaccharide (LPS) were investigated. Therefore, DCs of four independent donors were harvested after 12 hours co-culture with A. fumigatus, C. albicans and LPS and analyzed with Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a clustering of the A. fumigatus- and C. albicans-stimulated DCs. However, LPS and fungi-dependent gene expression showed more common similarities compared to the untreated control.

Whole genome sequencing of VMA11 deletion strain derived fluconazole adaptors in Candida albicans

Project description:Candida albicans strains SC5314 and YJB-T1891 were used as wild type to delete VMA11. The deletion strains (TJ926 and TJ927) were spread on YPD plate supplemented with 1μg/ml fluconazole. Randomly 96 adaptors derived from TJ926 and 96 adaptors derived from TJ927 were tested with disk diffusion assay. Among the resistant adaptors, randomly 15 adaptors (A4-A18) and 48 adaptors (A19-A66) derived from TJ926 were sequenced.

Suppression of biofilm formation by Candida albicans and multispecies by nepodin of Rumex root via hyphal inhibition

Project description:Biofilms are sessile microbial communities that are often resistant to conventional antimicrobial therapeutics and the host immune system. Candida albicans is an opportunistic pathogenic yeast and responsible for candidiasis. It readily colonizes host tissues and implant devices, and forms biofilms, which play an important role in pathogenesis and drug resistance. Its morphological transition from budding yeast to hyphal form and subsequent biofilm formation is regarded as the crucial factor for drug tolerance and virulence of Candida infections. In this study, nepodin (also called musizin) from Rumex japonicus root was investigated for antibiofilm, antihyphae, and antivirulence activities against fluconazole-resistant C. albicans strain. Nepodin at 2 µg/ml from Rumex plant effectively inhibited C. albicans biofilm formation by more than 90% but had no effect on planktonic cell growth. Also, Rumex root extract and nepodin inhibited hyphal growth and cell aggregation of C. albicans. Interestingly, nepodin also showed antibiofilm activity against Staphylococcus aureus or A. baumannii strains and two systems of dual biofilms of C. albicans and S. aureus or A. baumannii, respectively. Transcriptomic analysis using RNA-seq and qRT-PCR showed nepodin repressed the expressions of several hypha/biofilm related genes (ECE1, HWP1, and UME6) and overexpressed several transport genes (CDR4, CDR11, IFD6, and TPO2), which supported observed phenotypic changes.

Candida albicans: Control vs. sulfite-treated cells

Project description:Transcriptional profiling of Candida albicans cells comparing control untreated C. albicans cells with sulfite-treated C. albicans cells. Sulfite is a toxic molecule that C. albicans encounters in its human host. Both wild type and ∆zcf2 mutant cells were used. The goal was to determine the effects of sulfite on C. albicans gene expression, and to determine which of the genes areZcf2-depedent.

Whole genome sequencing of adaptors selected by sub-inhibitory amount of brefeldin A in Candida albicans

Project description:In Candida albicans, the lab strain SC5314 was grown in YPD broth supplemented with 4ug/ml brefeldin A for 24h. The culture was washed, diluted and spread on YPD. Randomly 120 colonies were tested for tolerance to brefeldin A. Two adaptors (FY200 and FY201) obtained tolerance. These two adaptors were sequenced.

Gene expression profiles of human immature dendritic cells co-cultivated with Aspergillus fumigatus, Candida albicans and LPS for 6h

Project description:In a whole-transcriptome study, cellular responses of DCs confronted with the fungi A. fumigatus, C. albicans or the bacterial cell wall component LPS were investigated. Therefore DCs of four independent donors were analyzed after 6 hours co-culture with A. fumigatus, C. albicans and LPS by Affymetrix whole genome expression arrays. In general, transcriptomic analysis revealed a clustering of the A. fumigatus and C. albicans stimulated DCs. However, LPS and fungi-dependent gene expression showed more common similarities compared to the untreated control. Stimulation with LPS induced a differential regulation of 2793 genes after 6h, while confrontation with A. fumigatus and C. albicans resulted in 743 and 974 differentially regulated genes, respectively. Kruppel-like factor 4 (KLF4) was identified as the only transcription factor that was down-regulated in DCs by both fungi but induced by stimulation with LPS.
