Transfection of Human Papillomavirus Type 16-E6E7 Gene and Establishment of an Infected Cell Line Model
To investigate the functions of HPV-16 E6E7 protein in the development of cervical cancer,a recombinant plasmid pEGFP-HPV16E6E7,containing green fluorescent protein and HPV-16 E6E7 proteins was constructed and was transfected into HPV-negative cell line C33A mediated by liposome.The efficiency of tranfection was determined by inverted fluorescent microscope and the expression of E6E7 was detected by Western blot.It showed that transfection of C33A cell and Caski cell by HPV-16 E6E7 gene established a pair of transfected cell types to study the carcinogenesis of E6 and E7 proteins.
