| Research Abstract |
The antisense approach was used to demonstrate the role of survivin on embryo development. Development of early embryos treated with antisense survivin oligonucleotides was arrested at the molura or early blastocyst stage with disruption of tubulin formation and abnormal nuclei, associated with apoptosis. The effect of the antisense was enhanced by cotreatment with an apoptosis-inducing reagent, staurosporine. In contrast, apoptosis induced by the antisense tratment was inhibited by caspase-3 and caspase-9 inhibitors. These results, indicate that survivin is an essential antiapoptotic gene expressed in preimplantation embryos and could protect the embryos from apoptosis by inducing an apoptotic pathway involving caspases.
