    • Apoptosis, necrosis and autophagy are influenced by metabolic energy sources in cultured rat spermatocytes 
      Bustamante Marín, Ximena; Quiroga, Clara; Lavandero González, Sergio; Reyes, Juan G.; Moreno, Ricardo D. (2012)
      Apoptosis, necrosis and autophagy are mechanistically related processes that control tissue homeostasis and cell survival. In the testis, germ cell death is important for controlling sperm output, but it is unknown whether ...
    • Energy requirements of odor transduction in the chemosensory cilia of olfactory sensory neurons rely on ... 
      Villar, Pablo; Delgado Arriagada, Ricardo; Vergara Montecinos, Cecilia; Reyes, Juan G.; Bacigalupo Vicuña, Juan (Soc Neuroscience, 2017-06-07)
      The mechanisms that power the physiological events occurring in cilia, flagella, and microvilli are of fundamental importance for the functions of these important and ubicuous organelles. The olfactory epithelium is mostly ...
    • Expression and distribution of facilitative glucose (GLUTs) and monocarboxylate/H + (MCTs) transporters in ... 
      Nunez-Parra, Alexia; Cortes-Campos, Christian; Bacigalupo Vicuña, Juan; García, María de los Angeles; Nualart, Francisco; Reyes, Juan G. (2011)
      Cell-to-cell metabolic interactions are crucial for the functioning of the nervous system and depend on the differential expression of glucose transporters (GLUTs) and monocarboxylate transporters (MCTs). The olfactory ...
    • Intracellular Ca2+ homeostasis in rat round spermatids 
      Berrios, Julio; Osses, Nelson; Opazo, Carlos; Arenas, Gloria; Mercado, Luis; Benos, Dale J.; Reyes, Juan G. (Elsevier, 1998)
      Intracellular calcium, [Caz+], can regulate meiotic progression of mammalian oocytes. However, the role of [Ca2+], in the regulation of the spermatogenic process and its cellular homeostatic mechanisms in spermatogenic ...
    • Intracellular pH regulation in rat round spermatids 
      Osses, Nelson; Pancetti, Floria; Benos, Dale J.; Reyes, Juan G. (Wiley-Blackwell Publishing Ltd, 1997)
      Intracellular pH has been shown to be an important physiological parameter in cell cycle control and differentiation, aspects that are central to the spermatogenic process. However, the pH regulatory mechanisms in spermatogenic ...
    • Lipid Metabolizing Enzyme Activities Modulated by Phospholipid Substrate Lateral Distribution 
      Salinas, Dino G.; Reyes, Juan G.; de la Fuente, Milton (2011)
      Biological membranes contain many domains enriched in phospholipid lipids and there is not yet clear explanation about how these domains can control the activity of phospholipid metabolizing enzymes. Here we used the surface ...
    • Permeability changes induced by polylysines in rat spermatids 
      Jorquera, Ramon A.; Berrios, Julio; Sans, Jorge; Vergara Montecinos, Cecilia; Benos, Dale J.; Reyes, Juan G. (2002)
      High molecular weight (HMW, >15 kDa) but not low molecular weight (LMW, <15 kDa) polylysines (PLs) bound and induced permeability changes in rat spermatid plasma membranes, estimated by Mn2+ quenching of intracellular ...
    • Zinc transport in mammalian cells 
      Reyes, Juan G. (American Physiological Society, 1996)
      The importance of zinc in cell physiology is related mainly to its intracellular involvement in enzyme catalysis, protein structure, protein- protein interactions, and protein-oligonucleotide interactions. The mechanisms ...
