摘要: The expression of the human insulin-like growth factor (hIGF-I) gene driven by the Fhx/P25 promoter in the silk glands of transgenic silkworms (Bombyx mori) and in transformed silkworm cells, was achieved using BmN cells transfected with a piggyBac vector, pigA3GFP-Fhx/P25-hIGF-ie-neo containing a neomycin-resistance gene (neo), a green fluorescent protein gene (gfp), an hIGF-I gene, and a helper plasmid containing the piggyBac transposase sequence under the control of the B. mori actin 3 (A3) promoter. We selected stably transformed BmN cells expressing hIGF-I using the antibiotic G418. The expression level of hIGF-I was about 450pg in 310 super(6) cells, determined by ELISA. The piggyBac vector was transferred into the silkworm eggs using sperm-mediated gene transfer. The expression level of hIGF-I per gram fresh posterior silk glands of G4 transgenic silkworms was approx. 150ng.
