Regulation of the Xenopus labial homeodomain genes, HoxA1 and HoxD1: activation by retinoids and peptide growth factors
Article Abstract:
HoxA1, a Xenopus labial homeodomain gene, is present around the circumference of neurula stage embryos and in mid brain, hind brain endolymphatic duct and spinal cord. Another Xenopus labial homeodomain gene HoxD1 is expressed in dorsolateral and ventral ectoderm. Expression of both genes in the ectoderm and mesoderm of gastrula stages is significantly induced by retinoic acid, and this induction is independent of protein synthesis. Expression of HoxD1 in animal caps is induced by the peptide growth factors and they exert no influence on the expression of HoxA1.
