The purpose of this study was to investigate the effect of aging on different parameters related to inflammation, oxidative stress and apoptosis in hearts from two types of male mice models: senescence-accelerated mice (SAM-P8) and senescence-accelerated-resistant (SAM-R1), and the influence of chronic administration of Growth Hormone (GH) on old SAM-P8 mice. Forty male mice were used. Animals were...
Aging could be due to the accumulation of oxidative damage. On the other hand, growth hormone (GH) and estrogen deficiency induce deleterious effects on different tissues, and hormonal replacement could counteract these effects. We have investigated whether GH and estrogen administration modify some parameters related to oxidative stress and inflammation in hepatocytes isolated from old ovariectomized...
. There are many theories of aging and parameters that influence lifespan, including genetic instability, telomerase activity and oxidative stress. The role of caloric restriction, metabolism and insulin and insulin-like growth factor-1 signaling in the process of aging is especially well conserved throughout evolution. These latter factors interact with each other, the former factors and histone...
