Gapmer

Gapmers are short DNA antisense oligonucleotide structures with RNA-like segments on both sides of the sequence. These linear pieces of genetic information are designed to hybridize to a target piece of RNA and silence the gene through the induction of RNase H cleavage. Binding of the gapmer to the target has a higher affinity due to the modified RNA flanking regions, as well as resistance to degradation by nucleases. Gapmers are currently being developed as therapeutics for a variety of cancers, viruses, and other chronic genetic disorders.
