Comparative expression of the mouse Sox1, Sox2 and Sox3 genes from pre-gastrulation to early somite stages
Whole mount in situ hybridisation was used to study the embryonic expression of the mouse HMG box-containing genes Sox1, Sox2 and Sox3 between 6.5 and 9.0 days post coitum (dpc). Sox2 and Sox3 are expressed in the epiblast and extraembryonic ectoderm of the egg cylinder, becoming restricted to the prospective neural plate and chorion at the onset of gastrulation. Sox3 is upregulated in the post...
متن کاملEpigenetic regulation of human SOX3 gene expression during early phases of neural differentiation of NT2/D1 cells
Sox3/SOX3 is one of the earliest neural markers in vertebrates. Together with the Sox1/SOX1 and Sox2/SOX2 genes it is implicated in the regulation of stem cell identity. In the present study, we performed the first analysis of epigenetic mechanisms (DNA methylation and histone marks) involved in the regulation of the human SOX3 gene expression during RA-induced neural differentiation of NT2/D1 ...
متن کاملReciprocal transcriptional regulation of Pou5f1 and Sox2 via the Oct4/Sox2 complex in embryonic stem cells.
Embryonic stem cells (ESCs) are pluripotent cells that can either self-renew or differentiate into many cell types. Oct4 and Sox2 are transcription factors essential to the pluripotent and self-renewing phenotypes of ESCs. Both factors are upstream in the hierarchy of the transcription regulatory network and are partners in regulating several ESC-specific genes. In ESCs, Sox2 is transcriptional...
متن کاملTranscriptional regulation of nanog by OCT4 and SOX2.
Nanog, Sox2, and Oct4 are transcription factors all essential to maintaining the pluripotent embryonic stem cell phenotype. Through a cooperative interaction, Sox2 and Oct4 have previously been described to drive pluripotent-specific expression of a number of genes. We now extend the list of Sox2-Oct4 target genes to include Nanog. Within the Nanog proximal promoter, we identify a composite sox...
متن کاملDistinct SoxB1 networks are required for naïve and primed pluripotency
Deletion of Sox2 from mouse embryonic stem cells (ESCs) causes trophectodermal differentiation. While this can be prevented by enforced expression of the related SOXB1 proteins, SOX1 or SOX3, the roles of SOXB1 proteins in epiblast stem cell (EpiSC) pluripotency are unknown. Here, we show that Sox2 can be deleted from EpiSCs with impunity. This is due to a shift in the balance of SoxB1 expressi...
