    • Arabidopsis thaliana zinc accumulation in leaf trichomes is correlated with zinc concentration in leaves 

      Ricachenevsky, Felipe Klein; Punshon, Tracy; Salt, David E.; Fett, Janette Palma; Guerinot, Mary Lou (2021) [Artigo de periódico]
      Zinc (Zn) is a key micronutrient for plants and animals, and understanding Zn homeostasis in plants can improve both agriculture and human health. While root Zn transporters in plant model species have been characterized ...

    • Brain zinc chelation by diethyldithiocarbamate increased the behavioral and mitochondrial damages in zebrafish subjected to hypoxia 

      Braga, Marcos Martins; Silva, Emerson Santos da; Moraes, Tarsila Barros; Schirmbeck, Gabriel Henrique; Rico, Eduardo Pacheco; Pinto, Charles Budaszewski; Rosemberg, Denis Broock; Dutra Filho, Carlos Severo; Dias, Renato Dutra; Oliveira, Diogo Losch de; Rocha, Joao Batista Teixeira da; Souza, Diogo Onofre Gomes de (2016) [Artigo de periódico]
      The increase in brain levels of chelatable zinc (Zn) in dysfunctions involving oxygen deprivation has stimulated the treatment with Zn chelators, such as diethyldithiocarbamate (DEDTC). However, DEDTC is a redox-active ...

    • Effects of zinc transporters on Cryptococcus gattii virulence 

      Schneider, Rafael de Oliveira; Padilha, Camila Diehl; Santos, Francine Melise dos; Piffer, Alicia Corbellini; Garcia, Ane Wichine Acosta; Kulmann, Marcos Iuri Roos; Schrank, Augusto; Silva, Lívia Kmetzsch Rosa e; Vainstein, Marilene Henning; Staats, Charley Christian (2015) [Artigo de periódico]
      Zinc is an essential nutrient for all living organisms because it is a co-factor of several important proteins. Furthermore, zinc may play an essential role in the infectiousness of microorganisms. Previously, we determined ...

    • Enhanced expression of OsNAC5 leads to up-regulation of OsNAC6 and changes rice (Oryza sativa L.) ionome 

      Wairich, Andriele; Vitali, Ariane; Adamski, Janete Mariza; Lopes, Karina Letícia; Duarte, Guilherme Leitão; Ponte, Lucas Roani; Costa, Henrique Keller; Menguer, Paloma Koprovski; Santos, Rinaldo Pires dos; Fett, Janette Palma; Sperotto, Raul Antonio; Ricachenevsky, Felipe Klein (2023) [Artigo de periódico]
      NAC transcription factors are plant-specific proteins involved in many processes during the plant life cycle and responses to biotic and abiotic stresses. Previous studies have shown that stress-induced OsNAC5 from rice ...

    • Modulation of zinc homeostasis in Acanthamoeba castellanii as a possible antifungal strategy against Cryptococcus gattii 

      Ribeiro, Nicole Sartori; Santos, Francine Melise dos; Garcia, Ane Wichine Acosta; Ferrareze, Patricia Aline Gröhs; Fabres, Laura Fuhrich; Schrank, Augusto; Silva, Lívia Kmetzsch Rosa e; Rott, Marilise Brittes; Vainstein, Marilene Henning; Staats, Charley Christian (2017) [Artigo de periódico]
      Cryptococcus gattii is a basidiomycetous yeast that can be found in the environment and is one of the agents of cryptococcosis, a life-threatening disease. During its life cycle, cryptococcal cells take hold inside ...

    • The homeostasis of iron, copper, and zinc in Paracoccidioides brasiliensis, Cryptococcus neoformans var. grubii, and Cryptococcus gattii : a comparative analysis 

      Silva, Mirelle Garcia; Schrank, Augusto; Bailão, Elisa Flávia L. C.; Bailão, Alexandre Melo; Borges, Clayton Luiz; Staats, Charley Christian; Parente, Juliana Alves; Pereira, Maristela; Izacc, Silvia Maria Salem; Giannini, Maria José Soares Mendes; Oliveira, Rosely Maria Zancopé; Silva, Lívia Kmetzsch Rosa e; Nosanchuk, Joshua Daniel; Vainstein, Marilene Henning; Soares, Célia Maria de Almeida (2011) [Artigo de periódico]
      Iron, copper, and zinc are essential for all living organisms. Moreover, the homeostasis of these metals is vital to microorganisms during pathogenic interactions with a host. Most pathogens have developed specific mechanisms ...

    • Transcriptional plasticity bufers genetic variation in zinc homeostasis 

      Barbosa, Alice Pita; Ricachenevsky, Felipe Klein; Wilson, Michael; Dottorini, Tania; Salt, David E. (2019) [Artigo de periódico]
      In roots of Arabidopsis thaliana, Zn can be either loaded into the xylem for translocation to the shoot or stored in vacuoles. Vacuolar storage is achieved through the action of the Zn/Cd transporter HMA3 (Heavy Metal ...
