A prochelator activated by beta-secretase inhibits Abeta aggregation and suppresses copper-induced reactive oxygen species formation.
(J Am Chem Soc, 2010-04-14)The intersection of the amyloid cascade hypothesis and the implication of metal ions in Alzheimer's disease progression has sparked an interest in using metal-binding compounds as potential therapeutic agents. In the present ... -
Characterization of Metal Binding Peptides Derived from Copper Trafficking Proteins
(2010)Copper was first released into the environment as the result of the mass generation of oxygen from photosynthetic bacteria roughly 2.7 billion years ago. While it proved to be poisonous to early life on Earth, those that ... -
Copper at the Interface of Chemistry and Biology: New Insights into hCtr1 Function and the Role of Histidine in Human Cellular Copper Acquisition
(2010)Mechanisms of copper homeostasis are of great interest partly due to their connection to debilitating genetic and neurological disorders. The family of high-affinity copper transporters (Ctr) is responsible for extracellular ... -
Copper signaling axis as a target for prostate cancer therapeutics.
(Cancer Res, 2014-10-15)Previously published reports indicate that serum copper levels are elevated in patients with prostate cancer and that increased copper uptake can be used as a means to image prostate tumors. It is unclear, however, to what ... -
Deficiency of α-1-antitrypsin influences systemic iron homeostasis.
(Int J Chron Obstruct Pulmon Dis, 2013)There is evidence that proteases and antiproteases participate in the iron homeostasis of cells and living systems. We tested the postulate that α-1 antitrypsin (A1AT) polymorphism and the consequent deficiency ... -
Four-decade responses of soil trace elements to an aggrading old-field forest: B, Mn, Zn, Cu, and Fe.
(Ecology, 2008-10)In the ancient and acidic Ultisol soils of the Southern Piedmont, USA, we studied changes in trace element biogeochemistry over four decades, a period during which formerly cultivated cotton fields were planted with pine ... -
Leveraging the Requirement of MEK1/2 Kinases for Copper to Inhibit the MAPK Pathway in Oncogenic BRAF-Driven Cancer
(2016)The gene BRAF is mutated to remain aberrantly activated in a large number of human malignancies, most prominently in melanoma. The most common mutation in BRAF is a missense mutation that substitutes glutamic acid for valine ... -
Mechanisms of Eukaryotic Copper Homeostasis
(2010)Copper (Cu) is a co-factor that is essential for oxidative phosphorylation, protection from oxidative stress, angiogenesis, signaling, iron acquisition, peptide hormone maturation, and a number of other cellular processes. ...
