    • Calcium mediates dorsoventral patterning of mesoderm in Xenopus 
      Palma, Verónica; Kukuljan Padilla, Manuel; Mayor, Roberto (Cell Press, 2001)
      Calcium signals participate in the differentiation of electrically excitable and nonexcitable cells; one example of this differentiation is the acquisition of mature neuronal phenotypes [1]. For example, transient elevations ...
    • Energetic effects of pre-hatch albumen removal on embryonic development and early ontogeny in Gallus gallus 
      Peña Villalobos, Isaac; Piriz, Gabriela; Palma, Verónica; Sabat Kirkwood, Alejandro Pablo (Frontiers Media S.A., 2017)
      © 2017 Peña-Villalobos, Piriz, Palma and Sabat. Studies on the yolk and albumen content in bird eggs, and the effects of variations in their relative loads in the phenotype of the birds, have revealed multiple consequences ...
    • Epigenetic signatures at the RUNX2-P1 and Sp7 gene promoters control osteogenic lineage commitment of ... 
      Sepulveda, Hugo; Aguilar, Rodrigo; Prieto, Catalina P.; Bustos, Francisco; Aedo Monsalve, Sócrates; Lattus Olmos, José; Van Zundert, Brigitte; Palma, Verónica; Montecino, Martín (Wiley, 2017)
      Wharton's Jelly mesenchymal stem cells (WJ-MSCs) are an attractive potential source of multipotent stem cells for bone tissue replacement therapies. However, the molecular mechanisms involved in their osteogenic conversion ...
    • Expression profiling identifies novel Hh/Gli-regulated genes in developing zebrafish embryos 
      Bergeron, Sadie A.; Milla, Luis A.; Villegas, Rosario; Shen, Meng Chieh; Burgess, Shawn M.; Allende Connelly, Miguel; Karlstrom, Rolf O.; Palma, Verónica (2008)
      The Hedgehog (Hh) signaling pathway plays critical instructional roles during embryonic development. Misregulation of Hh/Gli signaling is a major causative factor in human congenital disorders and in a variety of cancers. ...
    • Greater Growth of Proximal Metatarsals in Bird Embryos and the Evolution of Hallux Position in the Grasping Foot 
      Botelho, João Francisco; Smith Paredes, Daniel; Soto Acuña, Sergio; Núñez-León, Daniel; Palma, Verónica; Vargas, Alexander O. (John Wiley and Sons Inc., 2017)
      © 2016 Wiley Periodicals, Inc. In early theropod dinosaurs—the ancestors of birds—the hallux (digit 1) had an elevated position within the foot and had lost the proximal portion of its metatarsal. It no longer articulated ...
    • PPARβ/δ and PPARγ maintain undifferentiated phenotypes of mouse adult neural precursor cells from the ... 
      Bernal, Carolina; Araya, Claudia; Palma, Verónica; Bronfman, Miguel (Frontiers Research Foundation, 2015)
      © 2015 Bernal, Araya, Palma and Bronfman.The subventricular zone (SVZ) is one of the main niches of neural stem cells in the adult mammalian brain. Stem and precursor cells in this region are the source for neurogenesis ...
    • Sonic hedgehog (Shh)/Gli modulates the spatial organization of neuroepithelial cell proliferation in the ... 
      Rapacioli, Melina; Botelho, Joao; Cerda, Gustavo; Duarte, Santiago; Elliot, Matías; Palma, Verónica; Flores, Vladimir (2012)
      Background: Sonic hedgehog (Shh)/Gli pathway plays an important regulatory role on the neuroepithelial cells (NEc) proliferation in the dorsal regions of the developing vertebrate Central Nervous System. The aim of this ...
    • Sonic hedgehog in cancer stem cells: A novel link with autophagy 
      Milla, Luis A.; González-Ramírez, Claudia N.; Palma, Verónica (2012)
      The Sonic Hegdehog/GLI (SHH/GLI) pathway has been extensively studied for its role in developmental and cancer biology. During early embryonic development the SHH pathway is involved mainly in pattern formation, while in ...
    • The Netrin-4/Laminin γ1/Neogenin-1 complex mediates migration in SK-N-SH neuroblastoma cells 
      Villanueva, Andrea A.; Puvogel, Sofía; Lois, Pablo; Muñoz-Palma, Ernesto; Ramírez Orellana, Manuel; Lubieniecki, Fabiana; Casco Claro, Fernando; Gallegos, Iván; García-Castro, Javier; Sanchez-Gomez, Pilar; Torres, Vicente A.; Palma, Verónica (Taylor and Francis Inc., 2018)
      © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group. Neuroblastoma (NB) is the most common pediatric extracranial solid tumor. It arises during development of the sympathetic nervous system. Netrin-4 (NTN4), ...
    • The Netrin-4/Neogenin-1 axis promotes neuroblastoma cell survival and migration 
      Villanueva, Andrea A.; Falcón, Paulina; Espinoza, Natalie; Solano, R. Luis; Milla, Luis A.; Hernandez-SanMiguel, Esther; Torres, Vicente A.; Sanchez-Gomez, Pilar; Palma, Verónica (Impact Journals LLC, 2017)
      Neogenin-1 (NEO1) is a transmembrane receptor involved in axonal guidance, angiogenesis, neuronal cell migration and cell death, during both embryonic development and adult homeostasis. It has been described as a dependence ...
