Abstract:
Murine interleukin-4 gene(mIL-4) was transfected into mice glioblastoma cell line G422 by recombinant adenovirus vector. We detected mRNA transcription of target gene in gene modified tumor cells(G422-mIL4). High level of mouse IL-4 could be detected in the culture supernatant of G422-mIL4. When inoculated subcuatneously, the tumor growth of G422-mIL4 was significantly inhibited as compared to wild type G422 and LacZ gene modified G422( G422-LacZ) . The period of survival of mice inoculated with G422-mlL4 was significantly prolongated(p<0.01).
