본 연구에서는 hG-CSF의 발현을 유도적으로 조절하기 위한 FIV-Tet-On lentivirus vector system을 구축하고자 하였다. hG-CSF는 호중성구 계열 세포의 증식과 분화, 생존에 영향을 미치는 물질로서, 이 유전자의 발현을 증가시키기 위하여 FIV-Tet-On vector 상의 hG-CSF나 rtTA2SM2 서열의 3' 위치에 WPRE 서열을 도입하였다. 구축된 각각의 vector는 293FT 세포에 일시적으로 transfection하여 virus를 생산하였으며, 이 virus를 일차 배양 세포인 CEF와 PFF에 감염시켰다. 각 세포에 전이된 hG-CSF의 발현 양상을 관찰하기 위하여 doxycycline을 첨가하거나 첨가하지 않은 배지에서 배양한 후 quantitative real-time PCR, Western blot과 ELISA를 이용하여 hG-CSF 유전자의 발현 정도를 비교 측정한 결과, CEF에서는 WPRE가 hG-CSF의 3' 위치에 도입된 경우에 발현량과 유도율이 가장 높은 것으로 나타났고, PFF에서는 rtTA 서열의 3'위치에 도입된 경우에 발현량과 유도율이 가장 큰 것으로 확인되었다. 이 FIV-Tet-On vector system은 형질 전환 동물의 생산이나 유전자 치료에서 문제시되는 외래 유전자의 지속적인 과다 발현에 의한 개체의 생리적인 부작용을 최소화하기 위한 해결 방법으로 제시될 수 있을 것이다.

In this study, using FIV-based lentivirus vector system, we tried to express hG-CSF in tetracycline-controllable manner. hG-CSF influences the proliferation, differentiation, and survival of cells in the neutrophil lineage. To enhance stability and translation of hG-CSF transcript, WPRE sequence was also introduced into FIV-Tet-On vector at downstream region of either the hG-CSF gene or the sequence encoding rtTA. Primary culture cells (CEF, chicken embryonic fibroblast; PFF, porcine fetal fibroblast) infected with the recombinant FIV were cultured in the medium supplemented with or without doxycycline for 48 hours, and induction efficiency was measured by comparing the hG-CSF gene expression level using quantitative real-time PCR, Western blot and ELISA. Higher hG-CSF expression and tighter expression control were observed from the vector in which the WPRE sequence was placed at downstream of the hG-CSF (in CEF) or rtTA (in PFF) gene. This FIV-Tet-On vector system may be helpful in solving serious physiological disturbance problems which has continuously hampered successful production of transgenic animals and gene therapy.
