Description:
Studies were carried out to examine the effects of long-term recombinant human growth hormone (GH) therapy on longevity in rodents. In the first study, 150 18-month-old female F344 rats were divided into three groups of 50 rats per group: Group 1, solvent vehicle; Group 2, 10 μg GH/kg body weight three times per week; Group 3, 50 μg GH/kg body weight three times per week. GH and solvent vehicle therapies were started at 18 months of age and continued until all the animals died spontaneously. Serum insulin-like growth factor (IGF)-I was measured at 18 and 29 months of age and on 3-month-old rats. Serum IGF-I level decreased between 3 and 29 months of age. GH therapy reversed the decrease in a dose-dependent manner, with the 50 μg GH dose returning the serum IGF-I level to that of 3-month-old animals. However, statistical analysis revealed no significant effect of GH therapy on median life span …
