      Tada, Masazumi; Concha, Miguel L.; Heisenberg, Carl Philipp (Elsevier Ltd, 2002)
      Members of the Wnt family have been implicated in a variety of developmental processes including axis formation, patterning of the central nervous system and tissue morphogenesis. Recent studies have shown that a Wnt ...

      Non-dystrophic myotonias are a group of rare neuromuscular diseases linked to SCN4A or CLCN1 . Among the subtypes, myotonia permanens, associated with the Gly1306Glu variant of SCN4A , is a relatively less frequent but ...
    • Non-equivalent ligand selectivity of agonist sites in (α4β2) 2α4 nicotinic acetylcholine receptors: A key ... 
      Mazzaferro, Simone; Gasparri, Federica; New, Karina; Alcaino, Constanza; Faundez, Manuel; Vasquez, Patricio Iturriaga; Vijayan, Ranjit; Biggin, Philip C.; Bermudez, Isabel (American Society for Biochemistry and Molecular Biology Inc., 2014)
      The α4β2 nicotinic acetylcholine receptor (nAChR) is the most abundant nAChR type in the brain, and this receptor type exists in alternate (α4β2)2α4 and (α4β2)2β2 forms, which are activated by agonists with strikingly ...
