Characterization of CMIX, a chicken homeobox gene related to the Xenopus gene mix.1
Members of the TGFbeta, Wnt and FGF families act in concert to induce and pattern the mesoderm of gastrulating embryos. Downstream effectors for these growth factors include homeobox proteins, which also feed back to activate and repress upstream signaling pathways (e.g. Fainsod, A., Steinbeisser, H., De Robertis, E.M. 1994. On the function of BMP-4 in patterning the marginal zone of the Xenopu...
متن کاملCMIX, a paired-type homeobox gene expressed before and during formation of the avian primitive streak
We cloned a chicken homeobox gene closely related to the Xenopus Mix. 1 gene. CMIX is expressed early in embryogenis in a sickle-shaped area in the posterior zone of the blastoderm. With the beginning of gastrulation, CMIX transcripts are found in the primitive streak primordium, then in the young and medium-sized streak, however not in the mesoderm after its emergence. In the fully-extended st...
متن کاملPosterior expression of a homeobox gene in early Xenopus embryos.
The homeobox containing transcript Xhox-36 is expressed exclusively in the posterior mesoderm and ectoderm of early Xenopus embryos. Therefore, the transcript shows region-specific rather than tissue-specific expression in the gastrula and neurula, a time when cells are becoming committed to defined fates. Exposure of early embryos to LiCl, which shifts posterior cells to more anterior fates, r...
متن کاملExpression of the homeobox gene GBX2 during chicken development
We have examined the expression pattern of the GBX2 gene during chicken embryogenesis. First transcripts are found in the epiblast of a HH st. 3+ embryo. With the onset of neurogenesis, transcripts mark the posterior neuroectoderm. Later on, expression is detectable in the isthmic region, the hindbrain and the neural tube. We show that GBX2 transcripts, as well as the protein, mark the presumpt...
متن کاملThe chicken CdxA homeobox gene and axial positioning during gastrulation.
The chicken homebox containing gene, CdxA (formerly CHox-cad), was previously shown to be expressed during gastrulation. Localization of CdxA transcripts by in situ hybridization to tissue sections revealed that, during gastrulation, expression of this gene exhibits a posterior localization along the primitive streak. The transcripts are localized to epiblast cells in the vicinity of the primit...
