efg1 transcription factor is believed to be the main regulator of hyphal formation under many different conditions. in addition, it is responsible for positive regulation of the expression of several hyphal-specific genes. sap5, which encodes secreted aspartic proteinase, is one of the mentioned genes and is crucial for pathogenicity properties. in the present work we have established the exper...

Candida albicans is a major human fungal pathogen. One of the important features of C. albicans pathogenicity is the ability to form biofilms on mucosal surfaces and indwelling medical devices. Biofilm formation involves complex processes in C. albicans, including cell adhesion, filamentous growth, extracellular matrix secretion and cell dispersion. In this work, we characterized the role of th...
Current understanding of resistance and susceptibility to vulvovaginal candidiasis challenges existing paradigms of host defence against fungal infection. While abiotic biofilm formation has a clearly established role during systemic Candida infections, it is not known whether C. albicans forms biofilms on the vaginal mucosa and the possible role of biofilms in disease. In vivo and ex vivo muri...
POSTERS Analysis of sterol regulation in the Saccharomycotina. Many fungal pathogens grow on superficial and in internal sites in infected hosts, regions that have considerably different oxygen levels. A better understanding of the influence of hypoxia (low oxygen) on virulence and pathogenesis may lead to improved treatments against systemic fungal infections. Hypoxia induces filamentation of ...
background: the most important virulence factor which plays a central role in candida albicans pathogenesis is the ability of this yeast to alternate between unicellular yeast and filamentous hyphal forms. efg1 protein is thought to be the main positive regulating transcription factor, which is responsible for regulating hyphal-specific gene expression under most conditions. als3 is one of the ...
Scanning electron microscope (SEM) observations were used to analyze particular morphologies of Candida albicans clinical isolate (strain 82) and mutants defective in hyphae-promoting genes EFG1 (strain HLC52) and/or CPH1 (strains HLC54 and Can16). Transcription factors Efg1 and Cph1 play role in regulating filamentation and adhesion of C. albicans' morphologies. Comparative analysis of such mu...
The opportunistic fungal pathogen Candida albicans is a part of the normal flora but it also causes systemic candidiasis if it reaches the bloodstream. Upon being phagocytized by macrophages, an important component of innate immunity, C. albicans rapidly upregulates a set of arginine biosynthetic genes. Arginine, urea, and CO2 induced hyphae in a density-dependent manner in wild-type, cph1/cph1...
Although most components of the mitochondrial translation apparatus are encoded by nuclear genes, all known molecular defects associated with impaired mitochondrial translation are due to mutations in mitochondrial DNA. We investigated two siblings with a severe defect in mitochondrial translation, reduced levels of oxidative phosphorylation complexes containing mitochondrial DNA (mtDNA)-encode...
investigation the expression candida albicans efg1 gene in vaginal candidiasis and biofilm formation
candida albicans has the ability to change between yeast and hyphal cells and is known to be a virulence property. efg1gene of c.albicans is as a main transcription factor that plays pivotal roles in biofilm formation the aim of the current study is to investigate the presence of efg1 gene in candida albicans isolates from women with vaginal candidiasis and its impact on biofilm formation.we us...
