Description This programme studied the premature ageing Werner syndrome (WS) that provides a powerful model system to study human ageing biology. WS is associated with rapid cell ageing, in particular acceleration of replicative senescence (the ageing of dividing cells). We previously identified a role for stress-signalling in this accelerated cell ageing involving p38 MAP kinase that also regulates the production of proinflammatory molecules such as cytokines, high levels of which are associated with diseases such as osteoporosis and type II diabetes that are more common in WS. As therapeutic targeting of p38 is problematic due to toxicity issues, we wished to further refine this stress pathway by examining the role of the downstream target MK2 in cell ageing.



Using genetic modification and chemical drugs to target MK2, we asked whether MK2 inhibition prevents (or delays) cell ageing in cells from WS and non-WS individuals. We found that cell growth rates of immortal WS cells were not affected, whereas p38 inhibition increased growth rates; however, the stressed morphology of WS cells was corrected. Growth rates of mortal (primary) WS or non-WS cells were also not affected, but the stressed morphology of primary WS cells was corrected. The replicative capacity was increased for both WS and non-WS cells. Finally, MK2 inhibitors did not prevent stress-induced cell senescence. These data suggest that MK2 is not involved in stress-induced cell senescence, and add to our understanding of how cellular senescence may lead to in vivo human ageing and in the pathology of age-related inflammatory diseases.
Exploitation Route It will inform future attempts to study the interaction between inflammation and ageing and future therapies targeting ageing mechanisms
