NCIt definition : A second-generation antisense oligonucleotide against survivin mRNA with potential
antitumor activity. Gataparsen hybridizes to survivin mRNA, thereby blocking translation
of survivin protein, a member of the inhibitor of apoptosis (IAP) family. Survivin,
expressed during embryonal development, is upregulated in a variety of human cancers
while absent in most normal adult cells; its expression in tumors is associated with
a more aggressive phenotype, shorter survival times, and a decreased response to chemotherapy.
Silencing expression of survivin potentially leads to restoration of the apoptotic
process in cancer cells, thereby facilitating chemotherapeutic treatments.;
