網頁2024年11月28日 · Eteplirsen is a steric blocker directing the exclusion of the exon 51. By skipping exon 51, a truncated but partially functional dystrophin protein is produced shifting the severe DMD phenotype to that of the less severe phenotype of Becker muscular dystrophy, with functional albeit truncated versions of dystrophin. 網頁B: ASOs modulate target mRNA expression either by steric blocking (mixmers) or recruitment of RNase H (gapmers). Gapmers are composed of a central DNA region flanked at both ends by chemically modified ribonucleotides and recruit RNase H, which recognizes and cleaves DNA:RNA heteroduplexes. spencer rattler website https://jgson.net
