Ectopic expression of the Brachyury transcription factor upregulates only a subset of notochord expressed genes

ABSTRACT: The key notochord transcription factor Brachyury was ectopically expressed in Ciona embryos under the control of the FoxAa cis-regulatory region (which drives expression in neural, endodermal and mesenchymal lineages in addition to notochord). Misexpression of Brachyury induced 925 genes compared to a control reporter plasmid (Bra>GFP). There was only modest overlap with a set of notochord-enriched genes previously identified by RNAseq of flow-sorted notochord cells, indicating that Brachyury is not a notochord master regulator gene as strictly defined.

Brachyury controls Ciona notochord fate as part of a feedforward network [IV]

Project description:The notochord is a defining feature of the chordates. The transcription factor Brachyury (Bra) is a key regulator of notochord fate but here we show that it is not a unitary master regulator in the model chordate Ciona. Ectopic Bra expression only partially reprograms other cell types to a notochord-like transcriptional profile and a subset of notochord-enriched genes are unaffected by CRISPR Bra disruption. We identify Foxa.a and Mnx as potential co-regulators and find that combinatorial cocktails are more effective at reprograming other cell types than Bra alone. We reassess the network relationships between Foxa.a, and other components of the notochord gene regulatory network and find that Foxa.a expression in the notochord is regulated by vegetal FGF signaling. It is a direct activator of Bra expression and has a binding motif that is significantly enriched in the regulatory regions of notochord-enriched genes. These and other results indicate that Bra and Foxa.a act together in a regulatory network dominated by positive feed-forward interactions, with neither being a classically-defined master regulator.er

Expression profiling of Ciona intestinalis initial tailbud stage embryos expressing mutant forms of the transcription factor Ci-XBP1 in the notochord.

Project description:XBP transcription factors are well-known regulators of the the unfolded protein response and are required for plasma cell differentiation. However, recent studies have shown that the XBP1 gene is also expressed in the developing notochord of Ciona and various vertebrates, and to date its role in the formation of this organ is largely uncharacterized. We identified putative targets of Ci-XBP1 through a microarray screen, using RNAs extracted from embryos expressing mutant forms of this transcriptional regulator in the notochord. We expressed in the Ciona notochord a dominant-negative version of Ci-XBP1 (XBP DBD::GFP) by cloning its DNA-binding domain (DBD) downstream of the Ci-Brachyury (Ci-Bra) promoter. We created a constitutive activator form of Ci-XBP by fusing its DBD to the VP16 transactivation domain (Bra>XBP DBD::VP16::GFP). These constructs were introduced into 1-cell stage embryos and grown to the initial tailbud (iTb) stage to identify Ci-XBP notochord target genes.
