A mini-review of targeting gene-virotherapy of cancer Liu XY; Gu JFAi Zheng 2006[Oct]; 25 (10): 1320-2New progress has been made on the project "targeting gene-virotherapy of cancer" proposed by us, which is "targeting dual gene-virotherapy of cancer". By the use of two genes, all the xenograft tumors in nude mice could be completely eliminated. The researches have been published in international journals, such as Hepatology and Cancer Research (a highlight paper). In this study, a further superior strategy--"double targeting virus-dual gene therapy" was introduced. This strategy was specialized by the use of tumor specific promoter to control the tumor specific suppressor gene, such as alpha-fetoprotein (AFP), which controls hepatoma specific suppressor gene LFIRE or HCCS1. In addition, a second tumor specific promoter, such as hTERT or survivin was used to control E1A or E1B in the construct, as hTERT-E1A-AFP-E1B-HCCS1 or LFIRE, a double tumor specific promoter controlling hepatoma specific LFIRE or HCCS1 gene. By the combined use of this construct with a very strong antitumor construct, such as hTERT-E1A-AFP-E1B-IL-24, a strategy with both excellent tumor killing effect and excellent safety with very little damage to normal cells was obtained. Therefore, double targeting virus-dual gene therapy might be one of the most potential strategies for cancer treatment. Furthermore, a new type of interferon was also introduced, which might be an ideal antitumor drug.|Animals[MESH]|Gene Targeting/methods[MESH]|Genetic Therapy/*methods[MESH]|Neoplasms/*therapy[MESH]|Oncolytic Virotherapy/*methods[MESH] |
