With age, the cardiovascular system experiences substantial alterations in cellular morphology and function. The factors regulating these changes are unknown; however, the mitogen activated protein kinase (MAPK) pathways have emerged as critical components for mediating numerous cellular responses including control of cell growth, differentiation and adaptation. Here we compare the expression, basal activation and the ability of increased pressure to activate the MAPK pathways in adult (6 month old), aged (30 month old) and very aged (36 month old) Fischer 344 x Brown Norway F1 Hybrid rats. Histochemical analysis demonstrated an age-related increase in tunica media thickness of approximately 11% …
