Transcription factors in Candida albicans - environmental control of morphogenesis.
نویسنده
چکیده
Awareness of Candida albicans as a major human health threat has risen during recent years. Although infections by C. albicans can be relatively mild and superficial, systemic mycoses often occur in immunocompromised patients, or even as a consequence of long-term therapy with broad-spectrum antibiotics or of chemotherapy (reviewed by Odds, 1988). Effective antifungal agents which are free of side-effects are urgently needed. There is hope that recently developed techniques of manipulating C. albicans and the sequencing of its genome will lead to a thorough understanding of the virulence and biology of this fungal pathogen, thus offering the possibility of a knowledge-based approach to novel antifungal agents.

Expression of the Candida albicans morphogenesis regulator gene CZF1 and its regulation by Efg1p and Czf1p.
The ability of Candida albicans to transit between different cellular morphologies is believed to be important for virulence. Morphological transitions occur in response to a variety of environmental signals. One such signal is encountered when cells are grown in a semisolid matrix. An important regulator of cellular morphology is the putative transcription factor CZF1. Here we demonstrate that...
متن کاملEfg1p, an essential regulator of morphogenesis of the human pathogen Candida albicans, is a member of a conserved class of bHLH proteins regulating morphogenetic processes in fungi.
We identified a gene of the fungal pathogen Candida albicans, designated EFG1, whose high-level expression stimulates pseudohyphal morphogenesis in the yeast Saccharomyces cerevisiae. In a central region the deduced Efg1 protein is highly homologous to the StuA and Phd1/Sok2 proteins that regulate morphogenesis of Aspergillus nidulans and S. cerevisiae, respectively. The core of the conserved r...
متن کاملPost‐transcriptional gene regulation in the biology and virulence of Candida albicans
In the human fungal pathogen Candida albicans, remodelling of gene expression drives host adaptation and virulence. Recent studies revealed that in addition to transcription, post-transcriptional mRNA control plays important roles in virulence-related pathways. Hyphal morphogenesis, biofilm formation, stress responses, antifungal drug susceptibility and virulence in animal models require post-t...
متن کاملA Core Filamentation Response Network in Candida albicans Is Restricted to Eight Genes
Although morphological plasticity is a central virulence trait of Candida albicans, the number of filament-associated genes and the interplay of mechanisms regulating their expression remain unknown. By correlation-based network modeling of the transcriptional response to different defined external stimuli for morphogenesis we identified a set of eight genes with highly correlated expression pa...
متن کاملA Histone Deacetylase Adjusts Transcription Kinetics at Coding Sequences during Candida albicans Morphogenesis
Despite their classical role as transcriptional repressors, several histone deacetylases, including the baker's yeast Set3/Hos2 complex (Set3C), facilitate gene expression. In the dimorphic human pathogen Candida albicans, the homologue of the Set3C inhibits the yeast-to-filament transition, but the precise molecular details of this function have remained elusive. Here, we use a combination of ...
