(Submitter supplied) Clinical isolates of the human fungal pathogen Candida albicans show significant variation in their ability to undergo in vitro filamentation. In this study, we show that Nrg1, a key repressor of filamentation and filament specific gene expression in standard laboratory strain, has strain dependent functions, especially during infection.

(Submitter supplied) Goal of this study was to determine metabolic adaptation processes in C. albicans associated to hyphal morphogenesis. Accessory to the metabolic profiling the corresponding transcriptome was investigated. To identify media-specific and general adaptation three different hyphae stimuli were used (M199 pH 7.4, Human serum and N-Aectylglucosamine) were used and compared again two respective yeast conditions (SD and M199 pH 4). more...

(Submitter supplied) The opportunistic pathogenic fungus Candida albicans can cause devastating infections in severely compromised patients. Its ability to undergo a morphogenetic transition from yeast to filamentous forms allows it to penetrate tissues and cause damage, and the expression of a number of pathogenetic mechanisms are also coordinately regulated with this yeast-to-hyphae conversion. Therefore, it is widely considered that filamentation represents one of the main virulence factors of C. more...

(Submitter supplied) Candidiasis affects a wide variety of immunocompromised individuals, including HIV/AIDS patients and cancer patients on chemotherapy. Candida albicans, a major human fungal pathogen, accounts for about 50% of all cases, while the remainder are caused by the less pathogenic non-albicans Candida species (NACS). These species are believed to be less pathogenic, in part, because they do not filament as readily or robustly as C. more...

(Submitter supplied) Candida albicans and Candida dubliniensis are closely related species displaying differences in virulence and genome content, therefore providing potential opportunities to identify novel C. albicans virulence genes. C. albicans gene arrays were used for comparative analysis of global gene expression in the two species in reconstituted human oral epithelium (RHE). C. albicans (SC5314) showed upregulation of hypha-specific and virulence genes within 30 min postinoculation, coinciding with rapid induction of filamentation and increased RHE damage. more...

(Submitter supplied) Candida albicans is a diploid human fungal pathogen that displays significant genomic and phenotypic heterogeneity over a range of virulence traits and in the context of a variety of environmental niches. Here, we show that the effects of Rob1 on biofilm and filamentation virulence traits is dependent on both the specific environmental condition and the clinical strain of C. albicans. The C. albicans reference strain SC5314 is a ROB1 heterozygote with two alleles that differ by a single nucleotide polymorphism at position 946 resulting in a serine or proline containing isoform. more...

(Submitter supplied) Purpose: To identify downstream genetics targets of the Dfi1 pathway during Dfi1 activating conditions. Methods: WT and dfi1 null cells were grown in minimal media, then treated with either 4uM of the calcium ionophore A23187 or an equal volume of 100% ethanol vehicle. After 30 min of treatment, cells were collected for RNA extraction and analysis. RNA was extracted using the Qiagen RNAeasy kit, then sent to the Tufts University Core Facility for library prep and sequencing. more...

(Submitter supplied) The yeast-filament transition is essential for the virulence of a variety of fungi that are pathogenic to humans. N-acetylglucosamine (GlcNAc), a ubiquitous molecule in both the environment and host, is one of the most potent inducers of filamentation in Candida albicans and thermally dimorphic fungi such as Histoplasma capsulatum and Blastomyces dermatitidis. However, GlcNAc suppresses rather than promotes filamentation in Candida tropicalis, a fungal species that is closely related to C. more...

(Submitter supplied) Transcriptional response of Candida dubliniensis during hypha formation and environmental change (temperature, pH, density and nutrients). Transcript profiling of C. dubliniensis identified a core shared transcriptional response with C. albicans during hypha formation and growth at alkaline pH. However, C. albicans expresses several unique hypha-specific genes, including ALS3, HYR1 and SAP4 and 5. Transcript profiling also revealed a novel role for NRG1 in regulating ferric reductases in C. more...

(Submitter supplied) The Regulation of Ace2 and Morphogenesis (RAM) pathway is an important regulatory network in the human fungal pathogen Candida albicans. The RAM pathway’s two most well-studied components, the NDR/Lats kinase Cbk1 and its putative substrate, the transcription factor Ace2, have a wide range of phenotypes and functions. It is not clear, however, which of these functions are specifically due to the phosphorylation of Ace2 by Cbk1. more...

(Submitter supplied) The fungus Candida albicans is part of the human microbiome and mainly colonises the GI tract of healthy individuals. However, when the balance in the GI tract is disturbed, the fungus can switch from a commensal to a virulent lifestyle and can turn into a life-threatening pathogen. Life in the host is characterised by a constant struggle for nutrients, essential trace elements such as iron, copper and zinc are particularly important. more...

(Submitter supplied) Candida albicans is a part of the normal microbiome of human mucosa and is able to thrive in a wide range of host environments. As an opportunistic pathogen, the virulence of C. albicans is tied to its ability to switch between yeast and hyphal morphologies in response to various environmental cues, one of which includes nutrient availability. Thus, metabolic flexibility plays an important role in the virulence of the pathogen. more...

(Submitter supplied) The ability of the fungus Candida albicans to filament and form biofilms contributes to its burden as a leading cause of hospital-acquired infections. Biofilm development involves an interconnected transcriptional regulatory network (TRN) consisting of nine transcription factors (TFs) that bind both to their own regulatory regions and to those of the other network TFs. Here, we show that seven of the nine TFs in the C. more...
