Abstract

Antisense compositions targeted against an mRNA sequence coding for a selected protein, at a region having its 5′ end from 1 to about 25 base pairs downstream of a normal splice acceptor junction in the preprocessed mRNA, are disclosed. The antisense compound is RNase-inactive, and is a phosphorodiamidate-linked morpholino oligonucleotide containing uncharged phosphorodiamidate linkages interspersed with cationic phosphorodiamidate linkages. Such targeting is effective to inhibit natural mRNA splice processing, produce splice variant mRNAs, and inhibit normal expression of the protein.
