Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence linking the gene product to a pathway or mechanism linked to ageing
Description: PCNA is an important player in DNA replication and, probably, in DNA repair. It has been associated with pathways suspect of being involved in human ageing, and it interacts with WRN [440]. PCNA levels have also been linked to cellular proliferation in aged rats [581]. In humans, a hypomorphic PCNA mutation causes a syndrome displaying a neurodegenerative phenotype including short stature, hearing loss, premature aging, telangiectasia, neurodegeneration, and photosensitivity. Additionally, patient cells exhibit abnormalities in response to UV irradiation [3604]. Therefore, it is possible that PCNA influences human ageing even though more detailed studies are necessary to prove such hypothesis.
