(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) 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) tRNA modifications play important roles in maintaining translation accuracy in all domains of life. Disruptions in the tRNA modification machinery, especially of the anticodon stem loop, can be lethal for many bacteria and lead to a broad range of phenotypes in baker’s yeast. Very little is known about the function of tRNA modifications in host-pathogen interactions, where rapidly changing environments and stresses require fast adaptations. more...

(Submitter supplied) Candida albicans is an opportunistic fungal pathogen that can infect oral mucosal surfaces despite being under continuous flow from saliva. Previous studies have shown that under specific conditions C. albicans will form microcolonies that more closely resemble the biofilms formed in vivo than standard in vitro biofilm models. However, very little is known about these microcolonies, particularly genomic differences between these specialized biofilm structures and the traditional in vitro biofilms. more...

(Submitter supplied) Sfl1p and Sfl2p are two homologous heat shock factor-type transcriptional regulators that antagonistically control morphogenesis in Candida albicans, while being required for full pathogenesis and virulence. To understand how Sfl1p and Sfl2p exert their function, we combined genome-wide location and expression analyses to reveal their transcriptional targets in vivo together with the associated changes of the C. more...

(Submitter supplied) Candida albicans is the most common opportunistic fungal pathogen of humans and is also a benign member of the gastrointestinal (GI) tract microbiota. Morphological transitions and metabolic regulation are critical for C. albicans to adapt to the changing host environment. We generated a library of central metabolic pathway mutants in the tricarboxylic acid (TCA) cycle, and investigated the functional consequences of these gene deletions on C. more...

(Submitter supplied) Although Candida albicans and Candida dubliniensis are most closely related, both species significantly behave differently with respect to morphogenesis and virulence. In order to gain further insight into the divergent routes for morphogenetic adaptation in both species, we investigated qualitative along with quantitative differences in the transcriptomes of both organisms by cDNA deep sequencing. Following genome-associated assembly of sequence reads we were able to generate experimentally verified databases containing 6016 and 5972 genes for C. albicans and C. dubliniensis, respectively. About 95% of the transcriptionally active regions (TARs) contain open reading frames while the remaining TARs most likely represent non-coding RNAs. Comparison of our annotations with publically available gene models for C. albicans and C. dubliniensis confirmed approximately 95% of already predicted genes, but also revealed so far unknown novel TARs in both species. Qualitative cross-species analysis of these databases revealed in addition to 5802 orthologs also 399 and 49 species-specific protein coding genes for C. albicans and C. dubliniensis, respectively. Furthermore, quantitative transcriptional profiling using RNA-Seq revealed significant differences in the expression of orthologs across both species. We defined a core subset of 84 hyphal-specific genes required for both species, as well as a set of 42 genes that seem to be specifically induced during hyphal morphogenesis in C. albicans. Species specific adaptation in C. albicans and C. dubliniensis is governed by individual genetic repertoires but also by altered regulation of conserved orthologs on the transcriptional level.

(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) Analyzing culture supernatants of yeast and hyphal cells of Candida albicans by mass spectrometry, we found two close homologues of pathogenesis-related (PR-) 1 proteins, Rbe1p and Rbt4p, in the secretome of this human pathogen. By sequence homology, we assigned three yet not characterized open reading frames, ORF19.6200, ORF19.2787 and ORF19.2336, in addition to Rbe1p and Rbt4p to a novel family of proteins. more...

(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) Invasion of host tissue by the human fungal pathogen, Candida albicans is an important step during many forms of candidosis. However, not all C. albicans strains possess the same invasive and virulence properties. It is known for example that the two clinical isolates SC5314 and ATCC10231 differ in their ability to invade into host tissue and to cause infections. Strain SC5314 is invasive whereas strain ATCC10231 is non-invasive and strongly attenuated in virulence as compared to SC5314. more...
