Cancer gene therapy using a survivin mutant adenovirus.
We have constructed a replication-deficient adenovirus encoding a nonphosphorylatable Thr(34)-->Ala mutant of the apoptosis inhibitor survivin (pAd-T34A) to target tumor cell viability in vitro and in vivo. Infection with pAd-T34A caused spontaneous apoptosis in cell lines of breast, cervical, prostate, lung, and colorectal cancer. In contrast, pAd-T34A did not affect cell viability of prolifer...
متن کاملSuicide gene therapy for hepatocellular carcinoma cells by survivin promoter-driven expression of the herpes simplex virus thymidine kinase gene
The aim of this study was to investigate the selective killing effect of the herpes simplex virus-thymidine kinase/ganciclovir (TK/GCV) suicide gene system controlled by the survivin promoter on hepatocellular carcinoma (HCC) cells in vitro. Recombinant plasmid vectors driven by the survivin promoter were constructed. HepG2 HCC and LO2 normal huma...
متن کاملTelomerase promoter-driven cancer gene therapy.
Human telomerase is highly active in more than 85% of primary cancers, regardless of their tissue origins, but not in most differentiated somatic tissues. Because of this, telomerase recently has become a popular target of anticancer therapy and has been used as a marker of cancer. Similarly, telomerase promoters, especially telomerase reverse transcriptase (TERT) promoter, have been zealously ...
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 کاملBax-induction gene therapy of pancreatic cancer.
BACKGROUND Bax is a strong pro-apoptotic gene that induces programmed cell death when expressed. Human telomerase reverse transcriptase (hTERT) is the catalytic subunit for telomerase, an enzyme found to be active in more than 85% of human cancers. Recently, a binary adenoviral system (Ad/GT-Bax + Ad/hTERT-GV16) was constructed using the hTERT promoter to induce Bax gene expression in tumor cel...
