Age-related cellular copper dynamics in the fungal ageing model Podospora anserina and in ageing human fibroblasts [PDF]

open access: yes, 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.
