PDLIM7 and cancer: To investigate the feasibility of gene therapy in treating Epstein-Barr virus (EBV)-associated cancer by employing the suicide gene, herpes simplex virus thymidine kinase/ganciclovir (HSV-tk/GCV), which uses the signaling pathway through the HIV-long terminal repeat (LTR) gene which is expressed from a nuclear factor-κB (NF-κB)-binding motif-containing promoter that is regulated by EBV-latent membrane protein 1 (LMP1) via NF-κB.
