Potential relevance to the human ageing process
- Main reason for selection
- Entry selected based on indirect or inconclusive evidence linking the gene product to ageing in humans or in one or more model systems
- Description
GRN is an autocrine growth factor. Knockout mice exhibit decreased survival, with less than 50% of animals living more than 2 years, and signs of cellular ageing, though not necessarily progeroid features [3263]. Results from knockout mice also suggest a role for GRN in maintaining neuronal function during ageing [3442]. In humans, GRN mutations have been associated with dementia [3445], but whether GRN is involved in broader aspects of ageing is unknown.
