"Herpes simplex virus thymidine kinase (TK) gene transfer followed by ganciclovir (GCV) administration is an approach investigated for glioblastoma treatment. The bystander effect (BE) enhances the cytotoxic effect of this strategy by allowing the diffusion of phosphorylated GCV from TK-expressing cells toward neighboring TK negative cells," investigators in Canada report. "This transfer of toxic metabolites is mainly mediated via gap junctions that are composed of connexins. Downregulation and/or cytoplasmic localization of connexins are common in tumors, and should be detrimental to the success of the TK/GCV strategy. In this study, we investigated the level of...
