Abstract:
Purpose To observe the killing effect of HSV-TK/GCV system on osteosarcoma cells. Methods The eukaryotic exprssoin vector (tgCMV-HyTK) containing HSV-TK gene was transduced into human osteosarcoma cell lines SAOS-2 by DOTAP. Total RNA extracted from HSV-TK expressing cells (SAOS-2TK) were tested by RNA dot blot analysis. A chemosensitivity of SAOS-2TK cells to GCV and “bystander effect” were measured by means of MTT colrimetric assay. Results HSV-TK gene was expressed in SAOS-2TK cells. SAOS-2TK cells were susceptible to the cytotoxicity of GCV. A meaningful “bystander effect” was demonstrated. Conclusion HSV-TK/GCV system may kill selectively the human osteosarcoma cell line SAOS-2.
