Definition / general
  • Transcription factor essential for notochordal cell differentiation, elongation of axis and specification of posterior mesodermal elements (Mod Pathol 2009;22:996)
Pathophysiology
  • Brachyury (T) is founding member of T box (Tbx) family
  • Transcriptional activator expressed throughout the nascent mesoderm, tailbud and notochord
  • Involved in the induction and regional specification of mesoderm
  • Brachyury deficient embryos lack tail and trunk structures and die shortly after gastrulation (PLoS One 2011;6:e28394)
  • In tumor cells, induces epithelial-mesenchymal transition, an important step in progression toward metastasis (J Clin Invest 2010;120:533)
Interpretation
  • Nuclear staining
Uses by pathologists
Positive staining - normal
  • Spermatogonia
Positive staining - disease
Negative staining
