FlyTED: the Drosophila Testis Gene Expression Database
نویسندگان
چکیده
FlyTED, the Drosophila Testis Gene Expression Database, is a biological research database for gene expression images from the testis of the fruit fly Drosophila melanogaster. It currently contains 2762 mRNA in situ hybridization images and ancillary metadata revealing the patterns of gene expression of 817 Drosophila genes in testes of wild type flies and of seven meiotic arrest mutant strains in which spermatogenesis is defective. This database has been built by adapting a widely used digital library repository software system, EPrints (http://eprints.org/software/), and provides both web-based search and browse interfaces, and programmatic access via an SQL dump, OAI-PMH and SPARQL. FlyTED is available at http://www.fly-ted.org/.

OpenFlyData: An exemplar data web integrating gene expression data on the fruit fly Drosophila melanogaster
MOTIVATION Integrating heterogeneous data across distributed sources is a major requirement for in silico bioinformatics supporting translational research. For example, genome-scale data on patterns of gene expression in the fruit fly Drosophila melanogaster are widely used in functional genomic studies in many organisms to inform candidate gene selection and validate experimental results. Howe...
متن کاملP-209: Decreased Expression of Histone Acetyltransferase CDY1 Gene in Testis Tissue May Lead to Decreased Expression of Transition Protein (TNP) and Protamine (PRM) Genes,Causing Male Infertility
Background: Infertility is a complex medical problem. About 15% of couples are infertile, and male infertility being involved in roughly 50% of the cases. Among these, many cases are associated with a severe impairment of spermatogenesis. During the last stage of spermatogenesis (spermiogenesis), sperm chromatin endures complex modifications in which histones are lost and depositioned with tran...
متن کاملP-232: Gene Expression Analysis of the Histon Variant H2BFWT in Testis Tissues of Non-Obstructive Azoospermic Patients Referred to Royan Institute
Background: During the later stages of spermatogenesis, spermatid nuclear remodeling and condensation are associated with histone modifications and the sequential displacement of histones by transition proteins and then by protamines. In humans, approximately 15% of the sperm DNA remains packaged by histones in sequence-specific areas. The histone variant H2B, member W, testis-specific (H2BFWT)...
متن کاملExamination of the immunohistochemical localization and gene expression by RT-PCR of the oxytocin receptor in diabetic and non-diabetic mouse testis
Objective(s): The aim of this study was to determine Oxytocin receptor (OTR) gene expression and localization in diabetic and non-diabetic mouse testes by RT-PCR and immunohistochemistry, respectively. Materials and Methods: In this study, 18 male BALB/c mice (8–12 weeks old) were used and divided into three groups: diabetic, sham, and control. Streptozotocin (STZ) was applied to the diabetic g...
متن کاملP-198: Analysis of Expression Level of TEX12 Gene in Testis Tissues of Severe Oligozoospermic and Non-Obstructive Azoospermic Men
Background: During the first meiotic prophase, alignment and synapsis of the homologous chromosomes are mediated by the synaptonemal complex. Incorrect assembly of the synaptonemal complex leads to impaired recombination and cell death, which in humans, causes infertility in males. Testis-expressed gene 12 (TEX12) is a germ cell-specific gene that is located on the chromosome 11 (11q22) in huma...
