Abstract:
:Homeobox genes regulate multiple aspects of mouse development including the axial patterning in the central nervous system. Some of the more divergent members of this gene family are expressed in the anterior region of the central nervous system where the Hox genes are not expressed. We previously reported the isolation of a mouse homeobox gene, Dbx, from the forebrain. Here we describe its genomic structure, complete cDNA sequence, characterization of the basal promoter and the expression pattern at different stages of the developing embryo. During early and mid-gestation, Dbx expression is restricted to the telencephalon, diencephalon, dorsal mesencephalon and spinal cord. At later gestational stages, Dbx expression continues in the dorsal mesencephalon and diencephalon, in which expression is more restricted than at the earlier stages. Dbx transcripts were also detected in the primitive cerebellum. At all stages, the Dbx expressing regions contain a high proportion of proliferating cells, suggesting a role for Dbx in patterning the central nervous system during embryogenesis.
