ABSTRACT
Objective To study the activity of the survivin gene promoter in several tumor cell lines and evaluate the possible application of this promoter in tumor gene therapy. Methods ①The expressions of survivin gene in A549,MDA-MB231 and HepG2 cell lines were detected by RT-PCR and Western blotting.②Tumor cells(A549,MDA-MB231,HepG2) were transiently transfected by reporter plasmids containing different length of survivin promoter using lipofectamine.And 48 h later,the level of reporter gene expression was analyzed.Results There were different levels of survivin expression in A549,MDA-MB231 and HepG2 cell lines.Transient transfection assay approved that pLuc-surP-987,pLuc-surP-596,pLuc-surP-269 and pLuc-surP-158 showed high activity and 269 bp survivin promoter demonstrated the highest activity. Conclusion In transcriptional level,survivin promoter can activate the reporter gene in several tumor cell lines.It is a potential candidate promoter in tumor gene therapy.
