Differential gene expression of XenopusPitx1, Pitx2b and Pitx2c during cement gland, stomodeum and pituitary development
The members of the Pitx family of homeobox transcription factors have been involved in many aspects of vertebrate embryogenesis, like for example, development of teeth, eyes and limbs. We previously reported expression patterns and function of Pitx2c in the generation of laterality and asymmetric morphogenesis of heart and gastro-intestinal tract in mouse, frog and zebrafish (Development 126 (1...
متن کاملXpitx-1: a homeobox gene expressed during pituitary and cement gland formation of Xenopus embryos
Pitx-1 is a member of the family of bicoid-related vertebrate homeobox genes; it was originally identified as a tissue-specific transcriptional regulator of the proopiomelacortin gene. Here we report on the embryonic expression of Xpitx-1, which is expressed in the anterior neural ridge and in the cement gland Anlage during late gastrulation/early neurulation. In tadpole stage embryos Xpitx-1 t...
متن کاملExpression of hsp90 Alpha and hsp90 Beta during Xenopus laevis Embryonic Development
Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...
متن کاملxPitx1 plays a role in specifying cement gland and head during early Xenopus development.
Xenopus Pitx1 is a homeobox gene whose family members are structurally and functionally conserved in organisms as diverse as Drosophila, chick, mouse, human, and frog. Present as a maternal transcript, the gene is zygotically expressed during gastrulation in a dorsal streak of cells. This streak restricts to a small circular domain underlying the center of presumptive neural plate. Shortly ther...
متن کاملAn atlas of differential gene expression during early Xenopus embryogenesis
We have carried out a large-scale, semi-automated whole-mount in situ hybridization screen of 8369 cDNA clones in Xenopus laevis embryos. We confirm that differential gene expression is prevalent during embryogenesis since 24% of the clones are expressed non-ubiquitously and 8% are organ or cell type specific marker genes. Sequence analysis and clustering yielded 723 unique genes displaying a d...
