With sequencing of the chicken genome largely completed, significant effort is focusing on gene annotation, including acquiring information about the patterns of gene expression. The chicken embryo is ideally suited to provide detailed temporal and spatial expression information through in situ hybridization gene expression analysis in vivo. We have developed the Gallus expression in situ hybridization analysis (GEISHA) database and user interface (http://geisha.arizona.edu) to serve as a centralized repository of in situ hybridization photos and metadata from chicken embryos. This report describes the design and implementation the GEISHA database and Web site and illustrates its usefulness for researchers in the biomedical and poultry science communities. Results from a recent comprehensive expression analysis of microRNA expression in chicken embryos are also presented.

UI MeSH Term Description Entries
D002642 Chick Embryo The developmental entity of a fertilized chicken egg (ZYGOTE). The developmental process begins about 24 h before the egg is laid at the BLASTODISC, a small whitish spot on the surface of the EGG YOLK. After 21 days of incubation, the embryo is fully developed before hatching. Embryo, Chick,Chick Embryos,Embryos, Chick
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D017403 In Situ Hybridization A technique that localizes specific nucleic acid sequences within intact chromosomes, eukaryotic cells, or bacterial cells through the use of specific nucleic acid-labeled probes. Hybridization in Situ,Hybridization, In Situ,Hybridizations, In Situ,In Situ Hybridizations
D020869 Gene Expression Profiling The determination of the pattern of genes expressed at the level of GENETIC TRANSCRIPTION, under specific circumstances or in a specific cell.

D035683 MicroRNAs Small double-stranded, non-protein coding RNAs, 21-25 nucleotides in length generated from single-stranded microRNA gene transcripts by the same RIBONUCLEASE III, Dicer, that produces small interfering RNAs (RNA, SMALL INTERFERING). They become part of the RNA-INDUCED SILENCING COMPLEX and repress the translation (TRANSLATION, GENETIC) of target RNA by binding to homologous 3'UTR region as an imperfect match. The small temporal RNAs (stRNAs), let-7 and lin-4, from C. elegans, are the first 2 miRNAs discovered, and are from a class of miRNAs involved in developmental timing.
