Gli3 is required for Emx gene expression during dorsal telencephalon development.
Dentate gyrus and hippocampus as centers for spatial learning, memory and emotional behaviour have been the focus of much interest in recent years. The molecular information on its development, however, has been relatively poor. To date, only Emx genes were known to be required for dorsal telencephalon development. Here, we report on forebrain development in the extra toes (Xt(J)) mouse mutant ...
متن کاملThe transcription factor Foxg1 regulates the competence of telencephalic cells to adopt subpallial fates in mice.
Foxg1 is required for development of the ventral telencephalon in the embryonic mammalian forebrain. Although one existing hypothesis suggests that failed ventral telencephalic development in the absence of Foxg1 is due to reduced production of the morphogens sonic hedgehog (Shh) and fibroblast growth factor 8 (Fgf8), the possibility that telencephalic cells lacking Foxg1 are intrinsically inco...
متن کاملLoss of Gli3 enhances the viability of embryonic telencephalic cells in vitro.
The transcription factor Gli3 is important for brain and limb development. Mice homozygous for a mutation in Gli3 (Gli3Xt/Xt) have severe abnormalities of telencephalic development and previous studies have suggested that aberrant cell death may contribute to the Gli3Xt/Xt phenotype. We demonstrate that telencephalic cells from embryonic Gli3Xt/Xt embryos survive better and are more resistant t...
متن کاملMiz1 is required for early embryonic development during gastrulation.
Miz1 is a member of the POZ domain/zinc finger transcription factor family. In vivo, Miz1 forms a complex with the Myc oncoprotein and recruits Myc to core promoter elements. Myc represses transcription through Miz1 binding sites. We now show that the Miz1 gene is ubiquitously expressed during mouse embryogenesis. In order to elucidate the physiological function of Miz1, we have deleted the mou...
متن کاملDicer is required for embryonic angiogenesis during mouse development.
Dicer is a multi-domain protein responsible for the generation of short interfering RNAs (siRNAs) from long double-stranded RNAs during RNA interference. It is also involved in the maturation of microRNAs, some of which are transcriptional regulators of developmental timing in nematodes. To assess the role of Dicer in mammals, we generated Dicerex1/2 mice with a deletion of the amino acid seque...
