    • Brachyury expression in the adult ctenophore, Pleurobrachia bachei 

      Kareiva, Isaac; Moroz, Leonid; Swalla, Billie; Kohn, Andrea (2012)
      Brachyury is a transcription factor important for mesoderm formation in chordates. Ctenophores are basal metazoans with little known about their germ layer organization. For this reason, brachyury was used as a possible ...
    • Collagen type IV in the Ctenophore Pleurobrachia bachei 

      Churches, Nathan; Swalla, Billie; Moroz, Leonid; Kohn, Andrea (2012)
      The evolution of multicellular animals required the development of epithelial tissues that function in controlling the transport of molecules from one environment to another. Collagen proteins are crucial to the formation ...
    • Gone with the Wnts…. The Wnt Signaling Pathway in Pleurobrachia bachei 

      Bruders, Rebecca; Swalla, Billie; Moroz, Leonid; Kohn, Andrea (2012)
      Wnt signaling is known to be critical for proper embryonic development in most animals studied to date15. But key evolutionary questions on the origin and evolution of this pathway in the metazoan common ancestor are ...
    • Molgulid Ascidians Share a Unique Gene Complex 

      Wu, Peter; Seufert, Daniel; Swalla, Billie (2011-06)
      Typical chordate features found in ascidian tadpole larvae have been evolutionarily lost several times independently within the Molgulidae family. While tailed molgulids retain a tail with muscl ...
    • The Origins of Neurons and use of Glutamatergic Signaling in the Ctenophore: Pleurobrachia bachei 

      Swore, Josh; Moroz, Leonid; Swalla, Billie; Kohn, Andrea (2012)
      Ctnenophores are a group of marine, jelly like, comb bearing metazoans. This phylum consists of an estimated 100-­‐200 species (Mills CE, 2012). Ctenophores are similar to cnidarians in that ...
    • Out on a LIM: LIM homeobox genes in the ctenophore Pleurobrachia bachei 

      Sanford, Rachel; Swalla, Billie; Moroz, Leonid; Kohn, Andrea (2012)
      LIM homeobox (Lhx) gene family consists of six subfamilies of patterning genes which play a major role in the development of the nervous system and are found only in animals. We looked at their presence and expression ...
    • A Quest for novel Signaling Molecules in Pleurobrachia Bachei 

      Girardo, David Orion; Swalla, Billie; Moroz, Leonid; Kohn, Andrea (2012)
      The evolution of the nervous system is poorly understood, with broad implications in basic neuroscience and regenerative medicine. The unintuitive nervous system of the basal Ctenophores provides an insight into neuronal ...
