title: Construction and in vivo efficacy of a replication-deficient recombinant adenovirus encoding murine growth hormone.
abstract: We have constructed a recombinant, replication-deficient, first-generation adenovirus-encoding mouse GH (mGH), AdCMVmGH. This virus directed mGH production from an epithelial cell line in vitro in a dose-dependent manner. When injected into the quadriceps muscle or submandibular ducts of mGH-deficient Snell dwarf mice, AdCMVmGH resulted in the production of significantly elevated serum mGH levels. Furthermore, after i.m. injection, dwarf mice increased in weight by 8% over 4 days and close to 100% by 30 days. When AdCMVmGH was administered to 3- to 4-week-old rats by i.v. injection to assess general metabolic responses, serum mGH, insulin-like growth factor 1, triglycerides and cholesterol levels were significantly elevated. AdCMVmGH should be a valuable experimental tool for the controlled, directed expression of mGH in preclinical mouse model studies.
