Fluprostenol-Induced Mapk Signaling Is Independent Of Aging In Fischer 344/Nniahsd X Brown Norway/Binia Rat Aorta, Kevin M. Rice, Ernest M. Walker, Sunil K. Kakarla, Satyanarayana Paturi, Miaozong Wu, Sumit Narula, Eric R. Blough
Fluprostenol-Induced Mapk Signaling Is Independent Of Aging In Fischer 344/Nniahsd X Brown Norway/Binia Rat Aorta, Kevin M. Rice, Ernest M. Walker, Sunil K. Kakarla, Satyanarayana Paturi, Miaozong Wu, Sumit Narula, Eric R. Blough

The factors that regulate vascular mechanotransduction and how this process may be altered with aging are poorly understood and have not been widely studied. Recent data suggest that increased tissue loading can result in the release of prostaglandin F2 alpha (PGF2α) and other reports indicate that aging diminishes the ability of the aged aorta to activate mitogen activated protein kinase (MAPK) signaling in response to increased loading. Using ex vivo incubations, here we investigate whether aging affects the ability of the aorta to induce phosphorylation of extracellular signal-regulated kinase 1/2 (ERK½-MAPK), p38-MAPK, and Jun N-terminal kinase (JNK-MAPK) activation following stimulation …

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% …
