    • Ca2+ signals promote GLUT4 exocytosis and reduce its endocytosis in muscle cells 
      Li, Q.; Zhu, X.; Ishikura, S.; Zhang, D.; Gao, J.; Sun, Y.; Contreras Ferrat, Ariel Eduardo; Foley, K. P.; Lavandero González, Sergio; Yao, Z.; Bilan, Philip J.; Klip, Amira; Niu, W. (American Physiological Society, 2014)
      Elevating cytosolic Ca2+ stimulates glucose uptake in skeletal muscle, but how Ca2+ affects intracellular traffic of GLUT4 is unknown. In tissue, changes in Ca2++ leading to contraction preclude analysis of the impact of ...
    • Calcium signaling in insulin action on striated muscle 
      Contreras Ferrat, Ariel Eduardo; Lavandero González, Sergio; Jaimovich Pérez, Enrique; Klip, Amira (Churchill Livingstone, 2014)
      © 2014 Elsevier Ltd. Striated muscles (skeletal and cardiac) are major physiological targets of insulin and this hormone triggers complex signaling pathways regulating cell growth and energy metabolism. Insulin increases ...
    • Electrical stimuli release ATP to increase GLUT4 translocation and glucose uptake via PI3Kγ-Akt-AS160 in ... 
      Osorio Fuentealba, César; Contreras Ferrat, Ariel Eduardo; Altamirano, Francisco; Espinosa, Alejandra; Li, Qing; Niu, Wenyan; Lavandero González, Sergio; Klip, Amira; Jaimovich Pérez, Enrique (2013)
      Skeletal muscle glucose uptake in response to exercise is preserved in insulin-resistant conditions, but the signals involved are debated. ATP is released from skeletal muscle by contractile activity and can autocrinely ...
    • Insulin elicits a ROS-activated and an IP3-dependent Ca2+ release, which both impinge on GLUT4 translocation 
      Contreras Ferrat, Ariel Eduardo; Llanos Vidal, Paola; Vásquez, César; Espinosa, Alejandra; Osorio Fuentealba, César; Arias Calderón, Manuel; Lavandero González, Sergio; Klip, Amira; Hidalgo Tapia, María Cecilia; Jaimovich Pérez, Enrique (The Company of Biologists Ltd, 2014)
      Insulin signaling includes generation of low levels of H2O2; however, its origin and contribution to insulin-stimulated glucose transport are unknown. We tested the impact of H2O2 on insulin-dependent glucose transport ...
    • Myo1c binding to submembrane actin mediates insulin-induced tethering of GLUT4 vesicles 
      Boguslavsky, Shlomit; Chiu, Tim; Foley, Kevin P.; Osorio-Fuentealba, Cesar; Antonescu, Costin N.; Bayer, K. Ulrich; Bilan, Philip J.; Klip, Amira (2012)
      GLUT4-containing vesicles cycle between the plasma membrane and intracellular compartments. Insulin promotes GLUT4 exocytosis by regulating GLUT4 vesicle arrival at the cell periphery and its subsequent tethering, docking, ...
