Recombinant expression vector k14/c-myc-paav was constructed bearing the mouse c-Myc cDNA derived by the skin specific human keratin 14 promoter, then the linear vector was microinjected into the two pronucleus of the C57BL/6 fertilized eggs to produce transgenic mice.256 microinjected eggs were transferred, 6 of the foster mothers were pregnant and 44 adult mice were produced, two of them were positive transgenic mice confirmed by PCR and Southern blot analysis, transgenic rate was about 4%.
