Project description:Candida species are components of the normal intestinal microbiota and are under constant exposure to bacterial metabolites, including secondary bile salts. Here, we examined the effect of a secondary bile salt, sodium deoxycholate (NaDCA), on the formation of biofilms by Candida tropicalis. In contrast to C. albicans, C. tropicalis tended to maintain its absolute biofilm biomass and surface hydrophobicity in the presence of NaDCA. Fluorescent 3D microscopic imaging of the biofilm revealed that NaDCA treatment reduced filamentous projection to the top of the biofilm. RNA-seq analysis revealed that some genes, especially those associated with iron metabolism, were differentially expressed in NaDCA-treated C. tropicalis. Although NaDCA altered the appearance of C. tropicalis biofilms, analysis of the expression of key virulence factor genes encoding agglutinin-like sequences and candidalysin revealed that these genes were less affected by NaDCA in C. tropicalis than in C. albicans. High-iron exposure had a negative effect on C. tropicalis biofilm biomass. These results suggest a difference in the intestinal niche occupied by C. albicans and C. tropicalis according to the local availability of secondary bile salts.

Project description:Transcriptional profiling of a-type wor1 deleted cells and mixed a-type and alpha-type opaque cells under in vitro biofilm-forming conditions. Specifically, they were grown for two days at room temperature in a 12-well poly-styrene plate containing 1 ml of Lee's + Glucose liquid media. Samples were hybridized against a universal mixed reference sample of a-type cells in white and opaque states grown in Spider liquid media.

Project description:Phenotypic switching is a strategy by which microbial organisms adapt to environmental changes. The human fungal pathogens, Candida albicans and Candida tropicalis, are closely related species and capable of undergoing morphological transitions. C. albicans primarily exists in human or warm-blooded animals as a commensal, whereas C. tropicalis not only exists as a commensal but also is widely distributed in the environment. In this study, To elucidate the regulatory mechanism of environmental pH on white-opaque switching in C. tropicalis, we performed RNA-Seq analysis under three pH conditions (pH 5.0, pH 7.0, and pH 8.0).

Project description:Candida tropicalis is an opportunistic pathogen which causes candidiasis in immune-compromised individuals. It is one of the members of the non-albicans group of Candida that are known to be azole resistant and is frequently seen in individuals being treated for cancers, HIV-infection and bone-marrow transplant. Although the genome of C. tropicalis was sequenced in the year 2009, the genome annotation has not been supported by experimental validation. In the present study, we have carried out in-depth proteomic profiling of C. tropicalis using high-resolution Fourier transform mass spectrometry and mapped ~44% of the computationally predicted protein-coding genes with peptide level evidence. In addition to identifying 2,740 proteins in the cell lysate of this yeast, we also analysed the proteome of the conditioned media of C. tropicalis culture and identified several unique secreted proteins among a total of 780 proteins. By subjecting the mass spectrometry data derived from cell lysate and conditioned media to proteogenomic analysis, we identified 86 novel genes, 12 novel exons and corrected 49 computationally predicted gene models. To our knowledge, this is the first high-throughput proteomic study to refine the genome annotation of C. tropicalis.
