The Role Of Tbx2 In Germ Layer Suppression And Dorsoventral Patterning During Early Vertebrate Development, Shoshana Reich
The Role Of Tbx2 In Germ Layer Suppression And Dorsoventral Patterning During Early Vertebrate Development, Shoshana Reich
Dissertations, Theses, and Capstone Projects
The differentiation of the three primary germ layers is precisely regulated by inductive cues, the intracellular networks through which these signals are transduced, and a broad array of nuclear proteins, such as transcription factors and epigenetic modifiers. Precise regulation of these various factors is crucial to proper development. Members of the T-box family of DNA-binding proteins play a prominent role in the differentiation of the three primary germ layers. VegT, Brachyury, and Eomesodermin function as transcriptional activators, are expressed in the presumptive mesendoderm and, in addition to directly activating the transcription of endoderm- and mesoderm-specific genes, serve variously as regulators …

The Role Of T-Box Proteins In Vertebrate Germ Layer Formation And Patterning, Sushma Teegala
Dissertations, Theses, and Capstone Projects
All of the tissues in triploblastic organisms, with the exception of the germ cells, arise from the three germ layers, ectoderm, mesoderm and the endoderm. The identification of the genes that underlie the differentiation of these layers is crucial to our understanding of development. T-box family proteins are DNA-binding transcriptional regulators that play important roles during germ layer formation in the early vertebrate embryo. Well-characterized members of this family, including the transcriptional activators Brachyury and VegT, are essential for the proper formation of mesoderm and endoderm, respectively. To date, T-box proteins have not been shown to play a role in …
