Altered adherence in strains of Candida albicans harbouring null mutations in secreted aspartic proteinase genes

Secreted aspartic proteinase family of Candida tropicalis.

Medically important yeasts of the genus Candida secrete aspartic proteinases (Saps), which are of particular interest as virulence factors. Like Candida albicans, Candida tropicalis secretes in vitro one dominant Sap (Sapt1p) in a medium containing bovine serum albumin (BSA) as the sole source of nitrogen. Using the gene SAPT1 as a probe and under low-stringency hybridization conditions, three ...

Profile of Candida albicans-secreted aspartic proteinase elicited during vaginal infection.

Vaginal infections caused by the opportunistic yeast Candida albicans are a significant problem in women of child-bearing age. Several factors are recognized as playing a crucial role in the pathogenesis of superficial candidiasis; these factors include hyphal formation, phenotypic switching, and the expression of virulence factors, including a 10-member family of secreted aspartic proteinases....

Interaction Studies of Secreted Aspartic Proteases (Saps) from Candida albicans

The inhibition of Candida albicans secreted aspartyl proteinase by triangular gold nanoparticles

Objective(s): The aim of this study was to synthesize triangular gold nanoparticles, and then to evaluate their capability for inhibition of Candida albicans secreted aspartyl proteinase 2(Sap2).Materials and Methods: To synthesize the nanoparticles, hydrogen tetrachloroaurate and hexadecyl trimethyl ammonium bromide were incubated in presence of Sn(IV) meso-tetra(N-methyl-4-pyridyl) porphine t...

Exposure of Candida albicans to antifungal agents affects expression of SAP2 and SAP9 secreted proteinase genes.

OBJECTIVES To ascertain the effects of subinhibitory concentrations of several antifungal agents on a virulence factor: secreted proteinase (Sap) activity and expression of SAP genes in Candida albicans. METHODS Enzyme assays and growth measurements, GFP-SAP2 promoter constructs and fluorescence measurement, transcript profiling and RT-PCR. RESULTS For seven of eight C. albicans isolates te...
