Clin Exp Pediatr. 2002;45(3):354-361.   Published online March 15, 2002
Purpose : Selective introduction of genes conferring chemosensitivity into proliferating tumor cells may be used to treat cancer. We first investigated the bystander effect of retrovirus-mediated gene transfer of herpes simplex virus thymidine kinase(HSV-TK) gene to murine neuroblstoma cell line(neuro-2a) in vitro and in vivo. Second, we examined the mechanism and its enhancement of the bystander effect in murine neuroblastoma. Methods...
Tumor Vaccine Effect by IL-16 Gene Transfer into Murine Neuroblastoma Model
Hyun-Sang Cho, Chong Young Park
Clin Exp Pediatr. 2001;44(1):68-74.   Published online January 15, 2001
Purpose : Interleukin(IL)-16 is a potent chemoattractant factor for CD4＋ T cells, monocytes, and eosinophils. It up-regulates IL-2R on CD4＋ T lymphocytes and regulates the function of antigen presenting cells. We used retrovirus-mediated gene transfer of the human IL-16 gene into the neuro-2a cells, which is the murine neuroblastoma cell lines, to investigate whether locally secreted IL-16 might generate anti-tumor...
