Expression of NK-2 class homeobox gene Nkx2–6 in foregut endoderm and heart
NK-2 class homeobox genes are candidate patterning and lineage regulators in diverse organisms. We report here the embryonic expression pattern of murine member, Nkx2-6. In keeping with its vertebrate relatives, Nkx2-6 was transcribed in ventrolateral embryonic structures. Expression was first detected at E8.0 in endodermal walls of the foregut pocket, tissue destined to become pharyngeal floor...
متن کاملNKX 2 - 2 ( NK 2 homeobox 2 )
273 amino acids; 30133 Da. NKX2-2 is a member of the NK2 family of homeobox transcription factors. It has known roles in the development of the CNS as well as pancreatic beta cell differentiation. In the CNS NKX2-2 is known to be activated by SHH signaling which is important for its initial role in ventral patterning. NKX2-2 expression has additionally been shown to be critical for the differen...
متن کاملNK-2 class homeobox genes and pharyngeal/oral patterning: Nkx2-3 is required for salivary gland and tooth morphogenesis.
Head development in vertebrates requires reciprocal patterning interactions between cranial neural crest and the ectodermal, mesodermal and endodermal components of the branchial arches. Patterning elements within the pharyngeal endoderm and oral ectoderm appear to play defining roles in this process. Several homeobox genes of the NK-2 class (Nkx2-1, Nkx2-3, Nkx2-5 and Nkx2-6) are expressed reg...
متن کاملNkx2-9 is a novel homeobox transcription factor which demarcates ventral domains in the developing mouse CNS
Nkx homeobox transcription factors are expressed in diverse embryonic cells and presumably control cell-type specification and morphogenetic events. Nkx2-9 is a novel family member of NK2 genes which lacks the conserved TN-domain found in all hitherto known murine Nkx2 genes. The prominent expression of Nkx2-9 in ventral brain and neural tube structures defines a subset of neuronal cells along ...
متن کاملIdentification of upstream regulatory regions in the heart-expressed homeobox gene Nkx2-5.
Nkx2-5 marks the earliest recognizable cardiac progenitor cells, and is activated in response to inductive signals involved in lineage specification. Nkx2-5 is also expressed in the developing foregut, thyroid, spleen, stomach and tongue. One approach to elucidate the signals involved in cardiogenesis was to examine the transcriptional regulation of early lineage markers such as Nkx2-5. We gene...
