Potential relevance to the human ageing process
- Main reason for selection
- Entry selected based on evidence showing that the gene product to be a target of genes previously linked to ageing
- Description
The PDGFRA gene encodes a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. PDGFRA binds PDGFB and thus may be related to age-related changes in the heart [363]. With age, there is a decline in the PDGFRA levels of beta-cell in mice, accompanied by a reduction in beta-cell replication. The conditional inactivation of Pdgfra accelerates these changes, preventing neonatal beta-cell expansion and adult beta-cell regeneration. Similar results were observed in human beta-cells [2224]. Receptor tyrosine kinases have been found to be expressed in metastatic colon cancer [2225] and PDGFRA mutations were found in gastrointestinal tumours [2226]. PDGFRA has not been directly related to ageing, however.
