Targeting alternative splicing to upregulate protein expression

Potential application in antisense therapeutics: upregulation of targeted protein expression

Here is a new paper demonstrating techniques for targeting steric-blocking antisense oligos to alternatively-spliced transcripts undergoing NMD to alter the splicing and recover transcripts encoding useful proteins. This is a technique for antisense upregulation of a protein activity.
