Purpose: We compared the differences between parent hepatoma cell lines and
interleukin-2(IL-2) transduced hepatoma cell lines using N2A/IL-2 and
LNC/IL-2 retrovirus with regards to in vitro sensitivity to peripheral blood monocytes
and in vivo tumorigenic activity.
Materials and Methods: Retroviral vector and producer cell line were constructed and
IL-2 gene was transduced into the human hepatoma cell lines(SK-Hepl, Hep-G2,
Hep-3B). IL-2 secretion after IL-2 transduction was measured by ELISA. MTT assay
for in vitro sensitivity to peripheral blood monocytes was performed and the tumorigenic
activity was observed in BALB/c mice and nude mice.
Results: IL-2 secretion was 186 pg/106 cells/24 hrs in SK-Hepl cell line
and was 147 pg/106 cells/24 hrs in Hep-3B cell line with
N2A/IL-2 retroviral vector and was 55,000 pg/106 cells/24
hrs with LNC/IL-2 retroviral vector. In vitro sensitivity to peripheral blood monocytes
was increased by 163.8¡­254% in IL-2 transduced hepatoma cell
lines(Hep-3B/N2A/IL-2, Hep-G2/N2A/IL-2) compared to
those of the parent cell lines. The tumorigenicity was observed in 1 of 3 BALB/c mice
and all 3 nude mice. Simultaneous injection of 1¡¿107 cells of the parent
cell line(Hep-3B) into the right flank and IL-2 transduced cell line(Hep-3B/LNC/IL-2)
into the left flank of the three BALB/c mice and of 5¡¿105 cells for the
three nude mice resulted in a complete regression of the IL-2 modified tumor cell
line(Hep-3B/LNC/IL-2) in 3 weeks and the parent cell line(Hep-3B) in 5 weeks. But,
after the injection of 1.5¡¿107 cells for other five nude mice, the tumor of
the IL-2 transduced hepatoma cell line(Hep-3B/LNC/IL-2) was gradually disappeared,
and the tumor of the parent hepatoma cell line(Hep-3B) was initially decreased and then
gradually regrew 20 days later.
Conclusion: IL-2 transduced hepatoma cell lines secreting IL-2 became more sensitive
to peripheral blood monocytes and resulted in the increased antigenicity to the tumors
formed by IL-2 transduced hepatoma cell line and parent cell line, and finally resulted in
the regression of the tumors in experimental animals.
