| description | <p><strong><em>Background and Objectives:</em> </strong>Gene therapy is a new and specific method for therapy of leukemia. Antitelomerase agents can be used in cancer therapy. Telomeres are specialized heterochromatin structures that act as protective caps at the ends of linear eukaryotic chromosomes. Human telomeres consist of tandem repeats of the hexanucleotide sequence TTAGGG in double strand. Telomerase is detected in the majority of cancers, but not in normal tissue. Telomere maintenance in 80–95% of tumor cells is achieved by telomerase. The aim of this research was to assess the inhibitory effects of nano-oligonucleotides as a new nano technology method in gene therapy of leukemia in vitro.<strong></strong></p><p> </p><p><strong><em>Methods:</em> </strong>In this study, we employed→P5N3 phosphoramidate oliogoadenylate synthetic, called sense, antisense and scramble.<strong></strong></p><p> </p><p><strong><em>Results:</em></strong><strong> </strong>In this research, oligomers with.5 micromolr did not have any effect on telomerase phosphoramidate→P5activity.
