This paper provides some experimental support for targeting steric-blocking oligos to alter splicing and trigger nonsense-mediated decay. The paper compared uniform 2'-methoxyethyl phosphorothioate oligos with 2'-MOE phosphorothioate gapmers (steric blocking versus RNase-H competent, respectively).
