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 cellular model system
Description: Also known as p38, MAPK14 is activated in response to cellular stress and it can phosphorylate a number of transcription factors. It is also involved in the production of IL6 [137], and is an important player in cellular senescence [140]. In-vitro inhibition of p38 enhances the proliferative potential of mice muscle stem cells and restores the age-declined regenerative potential of stem cells populations [3640]. In senescent CD8+ T cells its inhibition increases proliferation, telomerase activity, mitochondrial biogenesis, and fitness, in a mTOR-independent manner [3641]. Mice without MAPK14 are anaemic due to failed definitive erythropoiesis [773]. Transgenic mice with induced MAPK14 activity in the heart died in 7-9 weeks [775]. MAPK14's responsiveness may change with ageing in mouse cells [176]. A role for MAPK14 in human ageing is so far unknown.
