Prodrugs for Gene-Directed Enzyme-Prodrug Therapy (Suicide Gene Therapy)
This review focuses on the prodrugs used in suicide gene therapy. These prodrugs need to satisfy a number of criteria. They must be efficient and selective substrates for the activating enzyme, and be metabolized to potent cytotoxins preferably able to kill cells at all stages of the cell cycle. Both prodrugs and their activated species should have good distributive properties, so that the resu...
متن کاملTargeted Expression of Suicide Gene by Tissue-Specific Promoter and MicroRNA Regulation for Cancer Gene Therapy
In order to realise the full potential of cancer suicide gene therapy that allows the precise expression of suicide gene in cancer cells, we used a tissue specific Epithelial cell adhesion molecule (EpCAM) promoter (EGP-2) that directs transgene Herpes simplex virus-thymidine kinase (HSV-TK) expression preferentially in EpCAM over expressing cancer cells. EpCAM levels are considerably higher in...
متن کاملRegulation of HSVtk gene by endogenous microRNA-122a in liver cell lines as suicide gene therapy
Aim Here, we use miR-122a that exhibits liver-specific expression for developing a post-transcriptional regulative system mediated by microRNAs. Background Gene therapy with adenovirus (Ad) vectors that express herpes simplex virus thymidine kinase (HSVtk) and ganciclovir (GCV) have been suggested as a therapeutic strategy to cancer. However, Ad vectors injected into tumors are dispersed into...
متن کاملSuicide Gene Therapy against Cancer
A major limitation of conventional chemotherapies used in cancer treatments today are low therapeutic indices and side effects that result from drug effects on normal tissues (off target). One of the most innovative approaches to developing antineoplastic agents with increased tumor selectivity is the use of suicide gene therapy. Suicide gene therapy involves delivering a gene product in proxim...
متن کاملSuicide gene therapy for plasma cell tumors.
Suicide gene therapy for plasma cell tumors was attempted in severe combined immunodeficient (SCID) mice injected with human myeloma cell lines. Initially, a ganciclovir-induced bystander effect was observed in vitro using myeloma cells transduced with a herpes simplex thymidine kinase (HSVtk) gene. Transduced cells injected subcutaneously (SC) into SCID mice could be eradicated by the administ...
