Web12 Nov 2024 · Nusinersen increments the capability of SMN2 to produce FL-SMN by binding to the intron-splicing silencer region N1 in the SMN2 pre-messenger RNA (pre-mRNA) promoting exon seven inclusion ( Singh et al., 2006 ). Since the drug cannot pass through the blood brain barrier (BBB), it must be intrathecally administered. WebSMN-AS1 ASOs delivered together with SMN2 splice-switching oligonucleotides additively increase SMN expression and improve survival of severe SMA mice.

WebSF2/ASF (SRSF1) and hnRNPA1 are two crucial splicing factors that are responsible for control of differential splicing of the SMN1 and SMN2 gene transcripts. SF2/ASF binds to an ESE located in SMN1 exon 7, [ 5 , 20 ] while a C>T polymorphism at the sixth nucleotide of SMN2 exon 7 creates an ESS that is recognised by hnRNPA1, thus leading to omission of … WebSMN2 as a Therapeutic Target SMN2 has been used as a potential target for SMA treatment for many years. This is because, unlike SMN1, SMN2 is present in all people with SMA. If …
