Gene Therapy with HSV1-sr39TK/GCV Exhibits a Stronger Therapeutic Efficacy Than HSV1-TK/GCV in Rat C6 Glioma Cells

Figure 3

Growth inhibition in cultured C6-TK and C6-sr39TK cells 72 hours after ganciclovir (GCV) administration. Cell survival rate (SR) was measured by MTT assay, which showed SR in C6-TK and, especially, the C6-sr39TK group was significantly decreased in a dose-dependent manner as compared with that of the control (*   versus  C6 group; **   versus  C6 group; ##   versus  C6-TK group).
