    • Acute Copper and Ascorbic Acid Supplementation Inhibits Non-heme Iron Absorption in Humans 
      Olivares Grohnert, Manuel; Figueroa Donoso, Constanza; Pizarro Aguirre, Fernando (Humana Press, 2016)
      The objective of the study is to determine the effect of copper (Cu) plus the reducing agent ascorbic acid (AA) on the absorption of non-heme iron (Fe). Experimental study with block design in which each subject was his ...
    • Antibacterial Effect of Copper on Microorganisms Isolated from Bovine Mastitis 
      Reyes Jara, Angélica; Cordero, Ninoska; Aguirre, Juan; Troncoso, Miriam; Figueroa Gronemeyer, Guillermo (Frontiers Media, 2016)
      The antimicrobial properties of copper have been recognized for several years; applying these properties to the prevention of diseases such as bovine mastitis is a new area of research. The aim of the present study was to ...
    • CCS mRNA transcripts and serum CCS protein as copper marker in adults suffering inflammatory processes 
      Araya, Magdalena; Gutiérrez, Ricardo; Arredondo Olguín, Miguel (Springer, 2014)
      The chaperone to Zn–Cu superoxide dismutase (CCS) has been postulated as a candidate copper indicator, changing in a consistent manner in induced and recovered copper deficiency, in experimental cell and animal models. ...
    • Copper Supplementation at 8 mg Neither Affects Circulating Lipids nor Liver Function in Apparently Healthy ... 
      Rojas Sobarzo, Loreto; Olivares Grohnert, Manuel; Brito, Alex; Suazo Romo, Miriam; Araya, Magdalena; Pizarro Aguirre, Fernando (Springer, 2013)
      Copper (Cu) deficiency has been reported to influence lipid metabolism, but the effects in humans are controversial. To evaluate the effects of 8 mg Cu/day supplementation (as copper sulfate) for 6 months on the lipid ...
    • Exploratory study: excessive iron supplementation reduces zinc content in pork without affecting iron and copper 
      Middleton Santibáñez, Maureen; Olivares Grohnert, Manuel Alonso; Espinoza, Alejandra; Arredondo Olguín, Miguel Armando; Pizarro Aguirre, Fernando Dagoberto; Valenzuela Venegas, Carolina Paz (MDPI, 2021)
      Currently, all pigs raised on intensive farms develop iron-deficiency anemia if they do not receive supplemental iron at birth. Weaning diets commonly contain high concentrations of iron, and the effect on the copper and ...
    • Mouse divalent metal transporter 1 is a copper transporter in HEK293 cells 
      Arredondo Olguín, Miguel; Mendiburo Seguel, María José; Flores, Sebastián; Singleton, Steven T.; Garrick, Michael D. (Springer Science+Business Media, 2014)
      Divalent Metal Transporter 1 (DMT1) is an apical Fe transporter in the duodenum and is involved in endosomal Fe export. Four protein isoforms have been described for DMT1, two from mRNA with an iron responsive element ...
    • Synergistic effect of copper and low temperature over Listeria monocytogenes 
      Latorre Mora, Mauricio; Quesille Villalobos, Ana María; Maza, Felipe; Parra, Angel; Reyes Jara, Angélica (Springer, 2015)
      The capacity to grow at low temperatures has allowed Listeria monocytogenes to become one of the primary food pathogens to date, representing a major public health problem worldwide. Several works have described the ...
    • Transcriptional activation of glutathione pathways and role of glucose homeostasis during copper imbalance 
      Quiroz, Natalia; Rivas, Nicole; Pozo, Talía del; Burkhead, Jason; Suazo Romo, Miriam; González, Mauricio; Latorre, Mauricio (Springer, 2015)
      Copper is an essential micronutrient for organism health. Dietary changes or pathologies linked to this metal induce changes in intracellular glutathione concentrations. Here, we studied the transcriptional activation of ...
