SOX17 directly activates Zfp202 transcription during in vitro endoderm differentiation.
SOX17 is a SRY-related high-mobility group (HMG) box transcription factor that is necessary for endoderm formation in multiple species. Despite its essential function during endoderm formation and differentiation, few direct targets of SOX17 are known. To identify targets of SOX17, we isolated SOX17 binding sites with a chromatin immunoprecipitation (ChIP)-cloning screen. SOX17-ChIP identified ...
متن کاملExpression of hsp90 Alpha and hsp90 Beta during Xenopus laevis Embryonic Development
Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...
متن کاملMaternal VegT is the initiator of a molecular network specifying endoderm in Xenopus laevis.
During cleavage stages, maternal VegT mRNA and protein are localized to the Xenopus embryo's vegetal region from which the endoderm will arise and where several zygotic gene transcripts will be localized. Previous loss-of-function experiments on this T-box transcription factor suggested a role for VegT in Xenopus endoderm formation. Here, we test whether VegT is required to initiate endoderm fo...

متن کاملCAP1 expression is developmentally regulated in Xenopus
We have cloned and characterized a Xenopus member of the cyclase associated protein (CAP) gene family. xCAP1 is expressed as a maternal transcript, but is up-regulated prior to gastrulation and subsequently localizes to head mesenchyme, lens, otic vesicle, and trunk mesoderm including the pronephros. At different stages, the gene also appears to differentiate surface from deep (sensorial) ectod...
