The segmentation genes runt and hairy are required for the proper transcriptional regulation of the pair-rule gene fushi tarazu during the blastoderm stage of Drosophila embryogenesis. The expression of different fushi tarazu reporter genes was examined in runt and hairy mutant embryos, as well as in runt over-expressing embryos in order to identify DNA elements responsible for mediating these ...
The Drosophila Runt protein is a member of a new family of transcriptional regulators that have important roles in processes extending from pattern formation in insect embryos to leukemogenesis in humans. We used ectopic expression to investigate runt's function in the pathway of Drosophila segmentation. Transient over-expression of runt under the control of a Drosophila heat-shock promoter cau...
A crucial step in generating the segmented body plan in Drosophila is establishing stripes of expression of several key segment-polarity genes, one stripe for each parasegment, in the blastoderm stage embryo. It is well established that these patterns are generated in response to regulation by the transcription factors encoded by the pair-rule segmentation genes. However, the full set of positi...
In animal development following the initial cleavage stage of embryogenesis, the cell cycle becomes dependent on intercellular signaling and controlled by the genomically encoded ontogenetic program. Runx transcription factors are critical regulators of metazoan developmental signaling, and we have shown that the sea urchin Runx gene runt-1, which is globally expressed during early embryogenesi...
The Core Binding Factor is a heterodimeric transcription factor complex in vertebrates that is composed of a DNA binding alpha-subunit and a non-DNA binding beta-subunit. The alpha-subunit is encoded by members of the Runt Domain family of proteins and the beta-subunit is encoded by the CBF beta gene. In Drosophila, two genes encoding alpha-subunits, runt and lozenge, and two genes encoding bet...
Osf2/Cbfa1, hereafter called Osf2, is a member of the Runt-related family of transcription factors that plays a critical role during osteoblast differentiation. Like all Runt-related proteins, it contains a runt domain, which is the DNA-binding domain, and a C-terminal proline-serine-threonine-rich (PST) domain thought to be the transcription activation domain. Additionally, Osf2 has two amino-...
In view of the severe wasting and diarrhea in animals with runt disease, it is remarkable how little the intestinal tract of these animals has been studied. Observers have noted in the small bowel atrophy of Peyer's patches,"' slightly increased numbers of leucocytes in the mucosa`' and clubbing and bridging of villi in the ileum.' Thymectomized rats with runt disease have developed ulceration ...
runx3, a member of runt-related transcription factor (runx) proteins with tumor suppressor effect, is a tissue–restricted and cancer related transcription factor that regulate cell proliferation and growth, as well as differentiation. in the present study, exogenous run3 was transiently expressed in ags (human gastric adenocarcinoma), with undetectable runx3 protein and in a549 (human lung carc...
