    • Calpains and proteasomes mediate degradation of ryanodine receptors in a model of cardiac ischemic reperfusion 

      Pedrozo Cibils, Zully; Sánchez, G.; Torrealba, N.; Valenzuela, Rodrigo; Fernández, Carolina; Hidalgo Tapia, María Cecilia; Lavandero González, Sergio; Donoso Laurent, Paulina (ELSEVIER SCIENCE BV, 2010-03)
      Type-2 ryanodine receptors (RyR2) - the calcium release channels of cardiac sarcoplasmic reticulum - have a central role in cardiac excitation-contraction coupling. In the heart, ischemia/reperfusion causes a rapid and ...
    • Cardiomyocyte ryanodine receptor degradation by chaperone-mediated autophagy 

      Pedrozo Cibils, Zully; Torrealba, Natalia; Fernández, Carolina; Gatica, Damián; Toro, Barbra; Quiroga, Clara; Rodríguez, Andrea E.; Sánchez, Gina; Gillette, Thomas G.; Hill, Joseph A.; Donoso Laurent, Paulina; Lavandero González, Sergio (the European Society of Cardiology, 2013)
      Aims Chaperone-mediated autophagy (CMA) is a selective mechanism for the degradation of soluble cytosolic proteins bearing the sequence KFERQ. These proteins are targeted by chaperones and delivered to lysosomes where ...
    • Polycystin-1 Is a Cardiomyocyte Mechanosensor That Governs L-Type Ca2+ Channel Protein Stability 

      Pedrozo Cibils, Zully; Criollo Céspedes, Alfredo; Battiprolu, Pavan K.; Morales, Cyndi R.; Contreras Ferrat, Ariel Eduardo; Fernández, Carolina; Jiang, Nan; Luo, Xiang; Caplan, Michael J.; Somlo, Stefan; Rothermel, Beverly A.; Gillette, Thomas G.; Lavandero González, Sergio; Hill, Joseph A. (Lippicott Williams & Wilkins, 2015)
      Background-L-type calcium channel activity is critical to afterload-induced hypertrophic growth of the heart. However, the mechanisms governing mechanical stress-induced activation of L-type calcium channel activity are ...
    • Preconditioning tachycardia decreases the activity of the mitochondrial permeability transition pore in the dog heart 

      Sánchez, Gina; Fernández, Carolina; Montecinos, Luis; Domenech, Raúl; Donoso, Paulina (2011)
      Cardioprotection by preconditioning is a central issue of current research on heart function. Several reports indicate that preventing the assembly and opening of the mitochondrial permeability transition pore (mPTP) ...
