Research Abstract

21-hydorxylase deficient (Cyp21a1D) mice were made by breeding with heterozygous of H-2aw18 haplotype mice. Retrovirus vector containing mouse Cyp21a1 cDNA was constructed and transmitted to fibroblasts cultured from 21OHD mice. Cyp21a1-induced fibroblasts were injected into Cyp21a1D mice. Adenoassociated virus vector containing Cyp21a cDNA (AAV-Cyp21a1) was constructed with pAAV-CMV-shuttle and injected into limbs muscles of 21OHD mice. Serum P4 and DOC concentrations were also measured before and after injection. Transplantation of the transgenic fibroblasts into Cyp21a1D mice showed slight change serum P4/DOC ratio. Transgenic 21OHD mice with AAV-Cyp21a1 showed increase DOC production and decreased P4/DOC ratio (1223 to 39.2) at 4weeks after injection. We succeeded recovering 21OH activity steroid production in in Cyp21a1D mice by introducing Cyp21a1 gene into muscle with adenoassociated virus vectors for 4 weeks.
