Potential relevance to the human ageing process
- Main reason for selection
- Entry selected based on evidence directly linking the gene product to ageing in a non-mammalian animal model
- Description
MAPK8, also known as JNK1, encodes many transcripts and is an important player in stress response. In invertebrates, there is evidence linking JNK signalling to ageing. Fruit flies with mutations that augment JNK signalling live longer [212]. Overexpression of JNK in roundworms also increases lifespan [60]. Changes in JNK1 with age have been reported in rat hepatocytes [768]. MAPK8-null mice showed defective T cell differentiation [761]. Mice without MAPK8 and MAPK9 die at embryonic stages [1715]. In mouse models of obesity, absence of MAPK8 decreased adiposity and improved insulin (INS) sensitivity [765]. Although MAPK8 could play a role in ageing-related diseases, further research is needed to determine how MAPK8 is related to human ageing.
