Age-related cellular copper dynamics in the fungal ageing model Podospora anserina and in ageing human fibroblasts [PDF]
, 2009 In previous investigations an impact of cellular copper homeostasis on ageing of the ascomycete Podospora anserina has been demonstrated. Here we provide new data indicating that mitochondria play a major role in this process.

Oxidation-assisted graphene heteroepitaxy on copper foil [PDF]
Nanoscale 2016, 2016 We propose an innovative, easy-to-implement approach to synthesize large-area singlecrystalline graphene sheets by chemical vapor deposition on copper foil. This method doubly takes advantage of residual oxygen present in the gas phase. First, by slightly oxidizing the copper surface, we induce grain boundary pinning in copper and, in consequence, the ...

Elesclomol induces copper‐dependent ferroptosis in colorectal cancer cells via degradation of ATP7A
Molecular Oncology, 2021 Cancer cells reprogram their copper metabolism to adapt to adverse microenvironments, such as oxidative stress. The copper chelator elesclomol has been reported to have considerable anticancer efficacy, but the underlying mechanisms remain largely ...
