Double-Target Antisense U7 snRNAs Promote Efficient Skipping of an Aberrant Exon in Three Human  -Thalassemic Mutations

Abstract excerpt

We have used three beta-thalassemic mutations, IVS2-654, -705 and -745, that create aberrant 5' splice sites (5' ss) and activate a common cryptic 3' ss further upstream in intron 2 of the human beta-globin gene to optimize a generally applicable exon-skipping strategy using antisense derivatives of U7 small nuclear RNA (snRNA). Introducing a modified U7 snRNA gene carrying an antisense sequence against the...
