Abstract Fibroblasts derived from the progeroid Werner syndrome show reduced replicative lifespan and a "stressed" morphology. both alleviated using the MAP kinase inhibitor SB203580. However. interpretation of these data is problematical because although SB203580 has the stress-activated kinases p38 and JNK1/2 as its preferred targets. https://www.kingarte.com/product-category/g-spot-vibrator/
