Research Abstract

We have tried to set up the treatment of Duchenne Muscular Dystrophy by promoting mutated exon skipping by using a chemical compound. We found that TG003, a specific inhibitor for Clk kinases, promotes exon skipping in the patient cells. We also comprehensively analyzed the effect of TG003 in pre-mRNA splicing and detected the introns whose excision is affected.
