Description

The tumor suppressor TP73 encodes a member of the p53 family of transcription factors involved in cellular responses to stress and participates in the apoptotic response to DNA damage. Compared to p53-deficient mice, p73-deficient mice also exhibited profound defects, including hippocampal dysgenesis, hydrocephalus, chronic infections and inflammation, as well as abnormalities in pheromone sensory pathways, but showed no increased susceptibility to spontaneous tumorigenesis [2203]. Old p73 +/- mice are more susceptible to neurodegeneration and showed decreased cognitive and motor function, brain atrophy, and neuronal degeneration compared to wild type [2204]. Mice lacking one of the isoforms (DeltaNp73) are viable and fertile but display the signs of neurodegeneration. Cells from these mice are more sensible to DNA-damage and have an increased p53-dependent apoptosis [2205]. Therefore, it is possible that TP73 plays a role in some aspects of ageing, in particular in the brain.
