The Ames procedure with Salmonella typhimurium strain TA100 was used to follow the detoxication by rat liver fractions of two series of aliphatic epoxides. The epoxides employed were 3-chloro-, 3,3-dichloro- and 3,3,3-trichloropropylene oxides and also p-methoxyphenyl-, phenyl- and p-nitrophenylglycidyl ethers. In our procedure with preincubation of the epoxides with rat liver fractions prior t...
The age-associated decline in tissue function has been attributed to ROS-mediated oxidative damage due to mitochondrial dysfunction. The long-lived Ames dwarf mouse exhibits resistance to oxidative stress, a physiological characteristic of longevity. It is not known, however, whether there are differences in the electron transport chain (ETC) functions in Ames tissues that are associated with t...
Growth hormone (GH) signaling stimulates the production of IGF-1; however, increased GH signaling may induce insulin resistance and can reduce life expectancy in both mice and humans. Interestingly, disruption of GH signaling by reducing plasma GH levels significantly improves health span and extends lifespan in mice, as observed in Ames dwarf mice. In addition, these mice have increased adipos...
