... in the context of regeneration. Here, we report that planarian glia regenerate after neurons, and that neurons are required for correct glial numbers and localization during regeneration. We also identify the planarian transcription factor-encoding gene ets-1 as a key regulator of glial cell maintenance...

.... Mariadason ABSTRACT Ets homologous factor (EHF) is a member of the epithelial-specific Ets (ESE) family of transcription factors. To investigate its role in development and epithelial homeostasis, we generated a series of novel mouse strains in which the Ets DNA-binding domain of Ehf was deleted in all...

... partner Lmo2. Thus, the two ETS factors Fli1 and Etv6, which drives the VEGFA expression in both somites and the DLP, sit at the top of the adult haemangioblast gene regulatory network (GRN). Furthermore, Gata2 is initially activated by Fli1 but later maintained by another ETS factor, Etv2. We also...

...-negative form of the sole Ci -FGFR (FGFR DN ) in the pigment cell precursors ( Davidson et al., 2006 ). Targeted expression of FGFR DN resulted in larvae lacking one or both pigment cells, showing normal morphology of the palps, tail and sensory vesicle. Perturbed larvae were assayed for the presence...

... only. Whereas the enhancers of both genes contain critical and interchangeable GATA sites, their distinct patterns of activation stem from the additional presence of two Ets sites in the Ci-otx enhancer. Initially characterized as activating elements in the neural lineages, these Ets sites additionally...

... expression in Gata2 -GFP knock-in embryos. Using founder transgenic analyses, we identified a Gata2 endothelium enhancer in the fourth intron and found that Gata2 regulation by this enhancer is restricted to the endocardial, lymphatic and vascular endothelium. Whereas disruption of three ETS-binding motifs...

... understood. During Drosophila oogenesis, a small group of cells called border cells exit the follicular epithelium to perform a stereotypic, invasive migration. We find that the ETS transcription factor Yan is required for border cell migration and that Yan expression is spatiotemporally regulated as border...

...Elizabeth R. Leight; Danielle Glossip; Kerry Kornfeld The LIN-1 ETS transcription factor inhibits vulval cell fates during Caenorhabditis elegans development. We demonstrate that LIN-1 interacts with UBC-9, a small ubiquitin-related modifier (SUMO) conjugating enzyme. This interaction is mediated...

... involved in FGF signaling and found that several members of the Fgf8 synexpression group are co-expressed with Scx in the dorsal sclerotome. Of particular interest were the Ets transcription factors Pea3 and Erm , which function as transcriptional effectors of FGF signaling. We show here...

... in its intronic sequence and that these multiple FREs comprise Ets-binding and Tcf/Lef-binding motifs that lie in juxtaposition. Functional and physical analyses indicate that signaling pathways of Fgf, Bmp and Wnt are integrated on these FREs to regulate the expression of Xcad3 in the posterior neural...

... specifically to the cement gland. Within this region, putative binding sites for Ets and ATF/CREB transcription factors are both necessary and sufficient to drive cement gland-specific expression, and cooperate to do so. Furthermore, while the putative ATF/CREB factor is activated by Otx2, a factor acting...

... formation of an embryonic midgut constriction at a precise location within the broad and uniform abdA expression domain. The constriction divides the abdA domain of the midgut into two chambers, the anterior one producing the Pointed (Pnt) ETS transcription factors and the posterior one the Odd-paired (Opa...

... as regulators that both repress their own expression and induce a large set of secondary-response late genes. We have identified recessive loss-of-function mutations in the early gene E74 , a member of the ets protooncogene family that encodes two related DNA-binding proteins, E74A and E74B. These mutations...
