      Aims Insulin-like growth factor 1 (IGF-1) is known to exert cardioprotective actions. However, it remains unknown if autophagy, a major adaptive response to nutritional stress, contributes to IGF-1-mediated cardioprotec ...
    • Histone deacetylase inhibition blunts ischemia/reperfusion Injury by inducing cardiomyocyte autophagy

(American Hearth Association, 2014)
      Background—Reperfusion accounts for a substantial fraction of the myocardial injury occurring with ischemic heart disease. Yet, no standard therapies are available targeting reperfusion injury. Here, we tested the hypothesis ...
    • Inhibition of class I histone deacetylases blunts cardiac hypertrophy through TSC2-dependent mTOR repression

(Amer Assoc Advancement Science, 2016)
      Altering chromatin structure through histone posttranslational modifications has emerged as a key driver of transcriptional responses in cells. Modulation of these transcriptional responses by pharmacological inhibition ...
    • Mechanical stretch increases L-type calcium channel stability in cardiomyocytes through a polycystin-1/AKT-dependent mechanism 

      Córdova, Andrés; Olmedo, Ivonne; Riquelme, J.; Barrientos, G.; Sánchez, G.; Gillette, Thomas G.; Lavandero González, Sergio; Chiong Lay, Mario; Donoso, P.; Pedrozo Cibils, Zully (Elsevier Science BV, 2018)
      The L-type calcium channel (LTCC) is an important determinant of cardiac contractility. Therefore, changes in LTCC activity or protein levels could be expected to affect cardiac function. Several studies describing LTCC ...
    • Metabolic stress - Induced activation of FoxO1 triggers diabetic cardiomyopathy in mice 

      Battiprolu, Pavan K.; Hojayev, Berdymammet; Jiang, Nan; Wang, Zhao V.; Luo, Xiang; Iglewski, Myriam; Shelton, John M.; Gerard, Robert D.; Rothermel, Beverly A.; Gillette, Thomas G.; Lavandero González, Sergio; Hill, Joseph A. (2012)
      The leading cause of death in diabetic patients is cardiovascular disease; diabetic cardiomyopathy is typified by alterations in cardiac morphology and function, independent of hypertension or coronary disease. However, ...
    • Metabolic stress-induced activation of FoxO1 triggers diabetic cardiomyopathy in mice 

      Battiprolu, Pavan K.; Hojayev, Berdymammet; Jiang, Nan; Wang, Zhao V.; Luo, Xiang; Iglewski, Myriam; Shelton, John M.; Gerard, Robert D.; Rothermel, Beverly A.; Gillette, Thomas G.; Lavandero González, Sergio; Hill, Joseph A. (AMER SOC CLINICAL INVESTIGATION INC, 2012-03)
      The leading cause of death in diabetic patients is cardiovascular disease; diabetic cardiomyopathy is typified by alterations in cardiac morphology and function, independent of hypertension or coronary disease. However, ...
    • 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)
