Project description:The process of calcium carbonate biomineralization has arisen multiple times during metazoan evolution. In the phylum Cnidaria, biomineralization has mostly been studied in the subclass Hexacorallia (i.e. stony corals) in comparison to the subclass Octocorallia (i.e. red corals); the two diverged approximately 600 million years ago. The precious Mediterranean red coral, Corallium rubrum, is an octocorallian species, which produces two distinct high-magnesium calcite biominerals, the axial skeleton and the sclerites. In order to gain insight into the red coral biomineralization process and cnidarian biomineralization evolution, we studied the protein repertoire forming the organic matrix (OM) of its two biominerals. We combined High-Resolution Mass Spectrometry and transcriptome analysis to study the OM composition of the axial skeleton and the sclerites. We identified a total of 102 OM proteins, 52 are shared between the two red coral biominerals with scleritin being the most abundant protein in each fraction. Contrary to reef building corals, the red coral is collagen-rich (10 collagen-like proteins). Agrin-like glycoproteins and proteins with sugar-binding domains are also predominant. Twenty-seven and 23 proteins were uniquely assigned to the axial skeleton and the sclerites, respectively. Their inferred regulatory function suggests that the difference between the two biominerals rather relies on the modeling of the matrix network than on specific structural components. At least one OM component appears to have been horizontally transferred from prokaryotes early during Octocorallia evolution. Our results support the view that calcification of the red coral axial skeleton likely represents a secondary calcification of an ancestral gorgonian horny axis. In addition, the comparison with stony coral skeletomes highlighted the low proportion of similar proteins between the biomineral OMs of hexacorallian and octocorallian corals, suggesting an independent acquisition of calcification in anthozoans.

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

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.
