    • Effect of ascorbate in the reduction of transferrin-associated iron in endocytic vesicles 
      Escobar, Aldo; Gaete, Victoria; Núñez González, Marco (Kluwer Academic Publishers-Plenum Publishers, 1992)
      Externally added ascorbate or NADH effectively reduced ferricyanide and promoted the exit of Fe3+ originated from acid-destabilized transferrin contained inside endocytic vesicles. The effect of ascorbate was mediated by ...
    • The cellular mechanisms of body iron homeostasis 
      Nũnez, Marco T.; Garate, Marco A.; Arredondo, Miguel; Tapia, Victoria; Muñoz, Patricia (Society of Biology of Chile, 2000)
      Cells tightly regulate iron levels through the activity of iron regulatory proteins (IRPs) that bind to RNA motifs called iron responsive elements (IREs). When cells become iron-depleted. IRPs bind to IREs present in the ...
