    • Activation of Chymotrypsin-Like Activity of the Proteasome during Ischemia Induces Myocardial Dysfunction and Death 
      Sánchez, Gina; Berrios, Daniela; Olmedo, Ivonne; Pezoa, Javier; Riquelme, Jaime A.; Montecinos, Luis; Pedrozo Cibils, Zully; Donoso Laurent, Paulina (Public Library Science, 2016)
      Inhibitors of the ubiquitin-proteasome system improve hemodynamic parameters and decrease the infarct size after ischemia reperfusion. The molecular basis of this protection is not fully understood since most available ...
    • High fat diet induced obesity produces spontaneous ventricular arrhythmias and increases the activity of ... 
      Sánchez, Gina; Araneda, Felipe; Peña, Juan Pedro; Finkelstein, José Pablo; Riquelme, Jaime A.; Montecinos, Luis; Barrientos Briones, Genaro; Llanos Vidal, Paola; Pedrozo Cibils, Zully; Said, Matilde; Bull Simpfendorfer, Ricardo; Donoso Laurent, Paulina (MDPI, 2018)
      Ventricular arrhythmias are a common cause of sudden cardiac death, and their occurrence is higher in obese subjects. Abnormal gating of ryanodine receptors (RyR2), the calcium release channels of the sarcoplasmic reticulum, ...
    • Inhibition of chymotrypsin-like activity of the proteasome by ixazomib prevents mitochondrial dysfunction ... 
      Sánchez Vergara, Gina; Chalmers, Stefanie; Ahumada, Xavier; Montecinos, Luis; Olmedo Alegría, Ivonne Odette; Eisner, Verónica; Riveros, Ana; Kogan, Marcelo J.; Lavandero González, Sergio; Pedrozo Cibils, Zully; Donoso Laurent, Paulina (Public Library Science, 2020)
      The heart is critically dependent on mitochondrial respiration for energy supply. Ischemia decreases oxygen availability, with catastrophic consequences for cellular energy systems. After a few minutes of ischemia, the ...
