Method for screening splicing variants or events

Abstract

The present invention relates to a high-throughput method of screening splicing variants of target genes as drug targets or for characterisation of their biological functions. The disclosure provides a method for the screening of splicing variants, comprising: (a) providing a first antisense oligonucleotide capable of inducing a first splice event on the target gene to express a first splicing variant, and a second antisense oligonucleotide capable of inducing a second splice event on the target gene to express a second splicing variant; (b) hybridising the first and second antisense oligonucleotides to a pre-mRNA of the target gene; and (c) characterising the effect of the splice event. In one embodiment, the first antisense oligonucleotide switches the splice event that expresses the second splicing variant towards one that expresses the first splicing variant, while the second antisense oligonucleotide switches the splice event that expresses the first splicing variant towards one that expresses the second splicing variant.
