    • Identification and subcellular localization of two isoenzymes of apyrase from Solanum tuberosum 

      Kettlun, Ana María; Leyton, Mario; Valenzuela, María Antonieta; Mancilla, Marta; Traverso Cori, A. (1992)
      Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
    • IDENTIFICATION AND SUBCELLULAR-LOCALIZATION OF 2 ISOENZYMES OF APYRASE FROM SOLANUM-TUBEROSUM 

      Kettlun, Ana María; Leyton, Mario; Valenzuela Pedevila, María Antonieta; Mancilla, Marta; Traverso Cori, A. (PERGAMON-ELSEVIER SCIENCE LTD, 1992-06)
      Two forms of ATP-diphosphohydrolase were identified in Solanum tuberosum tuber var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were over 10 for form A and 1 for form B. In the potato tuber homogenate the ...
    • PURIFICATION AND CHARACTERIZATION OF 2 ISOAPYRASES FROM SOLANUM-TUBEROSUM VAR ULTIMUS 

      Kettlun, Ana María; Urra, Raúl; Leyton, Mario; Valenzuela Pedevila, María Antonieta; Mancilla, Marta; Traverso Cori, A. (PERGAMON-ELSEVIER SCIENCE LTD, 1992-11)
      Two isoenzymes of ATP-diphosphohydrolase (apyrase) were extracted and purified from S. tuberosum var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were 1.0 (apyrase B) and ca 15.0 (apyrase A). They were ...

    • Signaling pathways involved in neuron-astrocyte adhesion and migration 

      Cárdenas,; Kong,; Alvarez,; Maldonado,; Leyton, (2014)
      Astrocytes in the normal brain possess a stellate shape reflecting their non-migratory properties. Alternatively, in neurodegenerative diseases or after injury, astrocytes become "reactive" in a process known as astrocytosis ...
