      Thy-1, an abundant mammalian glycoprotein, interacts with avβ3 integrin and syndecan-4 in astrocytes and thus triggers signaling events that involve RhoA and its effector p160ROCK, thereby increasing astrocyte adhesion to ...
    • Urrutia, Arles; Garcia-Angulo, Victor A.; Cortés Fuentes, Andrés; Caneo, Mauricio; Legüe, Marcela; Urquiza, Sebastián; Delgado, Scarlett E.; Ugalde, Juan; Burdisso, Paula; Calixto, Andrea (Public Library Science, 2020)
      Caenorhabditis elegans and its cognate bacterial diet comprise a reliable, widespread model to study diet and microbiota effects on host physiology. Nonetheless, how diet influences the rate at which neurons die remains ...
    • Hernando, Víctor; Inserte, Javier; Sartório, Carmem Luíza; Parra, Víctor M.; Poncelas-Nozal, Marcos; Garcia-Dorado, David (2010)
      Calpains contribute to reperfusion-induced myocardial cell death. However, it remains controversial whether its activation occurs during ischemia or reperfusion. We investigated the regulation and time-course of calpain ...
    • Posada Duque, Rafael; Ramírez, Omar A.; Härtel, Steffen; Inestrosa, Nibaldo C.; Bodaleo, Felipe; González Billault, Christian; Kirkwood, Alfredo; Cardona Gómez, Gloria (Birkhauser Verlag AG, 2017)
      © 2016, Springer International Publishing. CDK5 is a serine/threonine kinase that is involved in the normal function of the adult brain and plays a role in neurotransmission and synaptic plasticity. However, its over-regulation ...
    • Li, Yiran E.; Sowers, James R.; Hetz Flores, Claudio Andrés; Ren, Jun (Nature, 2022)
      The endoplasmic reticulum (ER) and mitochondria are interconnected intracellular organelles with vital roles in the regulation of cell signaling and function. While the ER participates in a number of biological processes ...
    • Cárdenas, Ana María; Arriagada, Christian; Allen, David D.; Caviedes, Raúl; Cortes, José F.; Martin, José; Couve, Eduardo; Rapoport, Stanley I.; Shimahara, Takeshi; Caviedes, Pablo (Academic Press Inc., 2002)
      We have established hippocampal cell lines from normal and trisomy 16 fetal mice, a model of human trisomy 21. Both cell lines, named H1b (derived from a normal animal) and HTk (trisomic) possess neuronal markers by ...
    • Mariqueo, Trinidad A.; Agurto, Adolfo; Muñoz, Braulio; San Martin, Loreto; Coronado, Cesar; Fernández-Pérez, Eduardo J.; Murath, Pablo; Sánchez, Andrea; Homanics, Gregg E.; Aguayo, Luis G. (American Physiological Society, 2014)
      Ethanol increased the frequency of miniature glycinergic currents [miniature inhibitory postsynaptic currents (mIPSCs)] in cultured spinal neurons. This effect was dependent on intracellular calcium augmentation, since ...
    • Cárdenas, Ana María; Allen, David D.; Arriagada, Christian; Olivares, Alexis; Bennett, Lori B.; Caviedes, Raúl; Dagnino Subiabre, Alexies; Mendoza, Isabel E.; Segura Aguilar, Juan; Rapoport, Stanley I.; Caviedes, Pablo (2002)
      We report the establishment of continuously growing cell lines from spinal cords of normal and trisomy 16 fetal mice. We show that both cell lines, named M4b (derived from a normal animal) and MTh (trisomic) possess ...
    • Cifuentes, Mariana; Advis, Juan P.; Shapses, Sue A. (2004)
      Weight reduction is a risk factor for bone loss. We previously showed that energy restriction is associated with a decrease in calcium (Ca) absorption and decreased estrogenic activity (EA). We hypothesized that this ...
    • Parra, Víctor M.; Macho Fisher, Pilar; Sánchez, Gina; Donoso Laurent, Paulina; Domenech Lira, Raúl (Lippincott Williams and Wilkins, 2015)
      We showed that exercise induces early and late myocardial preconditioning in dogs and that these effects are mediated through nicotinamide adenine dinucleotide phosphate reduced form (NADPH) oxidase activation. As the ...
    • Pacheco, Carla R.; Morales, Camila N.; Ramírez, Alejandra E.; Muñoz, Francisco J.; Gallegos, Scarlet S.; Caviedes, Pablo A.; Aguayo, Luis G.; Opazo, Carlos M. (Blackwell, 2015)
      It has been postulated that the accumulation of extracellular asynuclein (a-syn) might alter the neuronal membrane by formation of ‘pore-like structures’ that will lead to alterations in ionic homeostasis. However, this ...
    • Martínez, Jorge; Santibañez, Juan F. (1993)
      Blockade of the calcium channel inhibited, in a dose‐dependent manner, the proliferation of the IL‐3 dependent FDCP‐1 cell line and normal murine bone marrow cells. Similar results were obtained by lowering the amount of ...
    • Pihán, Philippe; Hetz Flores, Claudio (Elsevier, 2020)
