Essential role for mammalian copper transporter Ctr1 in copper homeostasis and embryonic development.
The trace metal copper (Cu) plays an essential role in biology as a cofactor for many enzymes that include Cu, Zn superoxide dismutase, cytochrome oxidase, ceruloplasmin, lysyl oxidase, and dopamine beta-hydroxylase. Consequently, Cu transport at the cell surface and the delivery of Cu to intracellular compartments are critical events for a wide variety of biological processes. The components t...
متن کاملDistinct mechanisms for Ctr1-mediated copper and cisplatin transport.
The Ctr1 family of integral membrane proteins is necessary for high affinity copper uptake in eukaryotes. Ctr1 is also involved in cellular accumulation of cisplatin, a platinum-based anticancer drug. Although the physiological role of Ctr1 has been revealed, the mechanism of action of Ctr1 remains to be elucidated. To gain a better understanding of Ctr1-mediated copper and cisplatin transport,...
متن کاملCopper/MYC/CTR1 interplay: a dangerous relationship in hepatocellular carcinoma
Free serum copper correlates with tumor incidence and progression of human cancers, including hepatocellular carcinoma (HCC). Copper extracellular uptake is provided by the transporter CTR1, whose expression is regulated to avoid excessive intracellular copper entry. Inadequate copper serum concentration is involved in the pathogenesis of Non Alcoholic Fatty Liver Disease (NAFLD), which is beco...
متن کاملThe copper transporter CTR1 regulates cisplatin uptake in Saccharomyces cerevisiae.
Resistance to cisplatin (DDP) is often accompanied by impaired accumulation in mammalian cells. The mechanism of impaired DDP accumulation is unknown, but copper uptake is diminished as well. We investigated the ability of the copper transporter CTR1 to control the accumulation of DDP in Saccharomyces cerevisiae. Parallel studies of copper and DDP cellular pharmacokinetics were carried out usin...
متن کاملRole of the copper transporter, CTR1, in platinum-induced ototoxicity.
The goal of this study was to determine the role of an influx copper transporter, CTR1, in the ototoxicity induced by cisplatin, a potent anticancer platinum analog used in the treatment of a variety of solid tumors. As determined through reverse transcriptase-PCR (RT-PCR), quantitative RT-PCR, Western blot, and immunohistochemistry, mouse CTR1 (Ctr1) was found to be abundantly expressed and hi...
