Project description:A cDNA microarray was constructed from the expressed sequence tags (ESTs) of different developmental stages, and comparative genome hybridization based on microarray procedures were carried out. Dermatophyte species are classified into three genera: Epidermophyton, Microsporum, and Trichophyton. To determine the relationship between these three groups comparative genome hybridization were used in our experiment. Trichophyton rubrum genmic DNA was reference DNA and labelled by Cy3 while the other dermatophytes genomic DNA were test DNA and labelled by CY5. Test and reference DNA were co-hybridized with the T. rubrum cDNA microarray and the numbers of genes shared between each species and T. rubrum were determined. Keywords: Comparative Genomic Hybridization

Keywords: Comparative Genomic Hybridization We used a Trichophyton rubrum cDNA microarray prepared in our lab through comparative genome hybridization of genomic DNA of 21 dermatophyte strains (belonging to 20 species) to elucidate the taxonomy and evolution profiles of 20 dermatophyte species. The numbers of genes shared between each species and T. rubrum were determined. Each strain DNA hybridized for 3 times. The slides were separated into three groups base on different datasets.

Project description:Conidia are considered to be the primary cause of skin and nail infections by Trichophyton rubrum. A cDNA microarray containing 10112 ESTs was developed and used to estimate the relative gene expression levels and changes of gene expression during conidial germination in time-course experiments.

Project description:A cDNA microarray was constructed from the expressed sequence tags (ESTs) of different developmental stages, and transcriptional profiles of the responses to 5-Flucytosine were determined. Keywords: Expression profiling by array The expression profiles of Trichophyton rubrum treated with 5-Flucytosine were compared to those of Trichophyton rubrum without drug. Each treatment has three replicates.

Project description:Trichophyton rubrum, an anthropophilic and cosmopolitan fungus, is the most common agent of superficial mycoses, causing rarely deep dermatophytosis in immunocompromised hosts. In this study, an infection condition of T. rubrum was modeled by adding human skin sections into a limited medium containing glucose to monitor T. rubrum gene expression patterns using cDNA microarrays on a global level. We found that exposure to human skin resulted in up-regulation of the expression levels of T. rubrum genes related to many cellular and biological processes, including transcription and translation, metabolism and secondary transport, stress response, and signaling pathways. These results provide a reference set of T. rubrum genes whose expression patterns change upon infection and reveal previously unknown genes that probably corresponding to proteins that should be considered as virulence factor candidates and potential new drug targets for T. rubrum infections.

Project description:Purpose: The dermatophyte Trichophyton rubrum is an anthropophilic filamentous fungus that infects keratinized tissues and is the most common etiologic agent isolated in cases of human dermatophytoses. To better understand the molecular effects of stress responses and fungal adaptability, we evaluated the effects of acriflavine, a cytoxic drug, on T. rubrum transcriptome in a time-course assay using high-throughput RNA-seq technology. Results: RNA-seq generated approximately 200 million short reads that were mapped to the Broad Institute’s Dermatophyte Comparative Database before differential gene expression analysis. A subset of 490 genes modulated in response to stress caused T. rubrum exposure to acriflavine were identified. These genes are involved in various cellular processes such as oxidation-reduction reactions, transmembrane transport, metal ion binding, and pathogenicity. The genes involved in pathogenicity were down-regulated, suggesting that this drug interferes with virulence factors that allow the establishment and maintenance of host infection. Conclusion: The results obtained in this large-scale analysis provide insights into the molecular events underlying the stress responses of T. rubrum Acriflavine.
