  • Establishment and identification of human cervical cancer cell line C33A stably expressing human papillomavirus type 58 E6E7 fusion gene

    The study was performed to construct a human cervical cancer cell line C33A which can stably express HPV58E6E7 fusion gene. Firstly, C33A cells were transfected with the recombinant lentivirus LV-HPV58E6E7 which contained HPV58E6E7 fusion gene, and the stably transfected cells (LV-HPV58E6E7/C33A) were screened out by flow cytometry. MTT was used to observe the growth of LV-HPV58E6E7/C33A cells and flow cytometry was carried out to detect the cell cycle. LV-HPV58E6E7/C33A cells were inoculated into the left armpits of nude mice. Then, the transcription and expression of HPV58E6E7 fusion gene was detected by qRT-PCR and Western blot, respectively. The results showed that HPV58E6E7 fusion gene can promote the proliferation of C33A cells. HPV58E6E7 fusion gene can be stably transcripted and expressed in vaccinated nude mice. The conclusion indicated that we successfully established a cervical cancer cell line LV-HPV58E6E7/C33A which can stably express HPV58E6E7 fusion gene. This cell line will provide an antigen cell line for the immune effect detection of HPV58 therapeutic vaccine.
