Dual-targeting snRNA gene therapy rescues STMN2 and UNC13A splicing in TDP-43 proteinopathies.
bioRxiv : the preprint server for biology · 2025
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder caused by the selective deterioration of motor neurons in the central nervous system (CNS). A key driver of this pathogenesis is nuclear loss of ALS-associated protein TDP-43, leading to mis-splicing of TDP-43 …

Enhancing RNA base editing on mammalian transcripts with small nuclear RNAs.
Nature chemical biology · 2025
Endogenous uridine-rich small nuclear RNAs (U snRNAs) form RNA-protein complexes to process eukaryotic pre-mRNA into mRNA. Previous studies have demonstrated programmable U snRNA guide-targeted exon inclusion and exclusion. Here we investigated whether snRNAs can also enhance RNA base editing over …

Strategies for programmable manipulation of alternative splicing.
Current opinion in genetics & development · 2024 · 89: 102272
Alternative splicing (AS) plays a pivotal role in protein diversity and mRNA maturation. Programmable control of targeted AS events is of longstanding interest in RNA biology, promising correction of dysregulated splicing in disease and discovery of AS events. This review …

Inhibition of RNA splicing triggers CHMP7 nuclear entry, impacting TDP-43 function and leading to the onset of ALS cellular phenotypes.
Neuron · 2024 · 112(24): 4033-4047.e8
Amyotrophic lateral sclerosis (ALS) is linked to the reduction of certain nucleoporins in neurons. Increased nuclear localization of charged multivesicular body protein 7 (CHMP7), a protein involved in nuclear pore surveillance, has been identified as a key factor damaging nuclear …

Large-scale map of RNA-binding protein interactomes across the mRNA life cycle.
Molecular cell · 2024 · 84(19): 3790-3809.e8
mRNAs interact with RNA-binding proteins (RBPs) throughout their processing and maturation. While efforts have assigned RBPs to RNA substrates, less exploration has leveraged protein-protein interactions (PPIs) to study proteins in mRNA life-cycle stages. We generated an RNA-aware, RBP-centric PPI map …

Small nuclear RNAs enhance protein-free RNA-programmable base conversion on mammalian coding transcripts.
bioRxiv : the preprint server for biology · 2024
Endogenous U small nuclear RNAs (U snRNAs) form RNA-protein complexes responsible for eukaryotic processing of pre-mRNA into mature mRNA. Previous studies have demonstrated the utility of guide-programmable U snRNAs in targeted exon inclusion and exclusion. We investigated whether snRNAs can …

Remodeling oncogenic transcriptomes by small molecules targeting NONO.
Nature chemical biology · 2023 · 19(7): 825-836
Much of the human proteome is involved in mRNA homeostasis, but most RNA-binding proteins lack chemical probes. Here we identify electrophilic small molecules that rapidly and stereoselectively decrease the expression of transcripts encoding the androgen receptor and its splice variants …

Engineered U1 snRNAs to modulate alternatively spliced exons.
Methods (San Diego, Calif.) · 2022 · 205: 140-148
Alternative splicing accounts for a considerable portion of transcriptomic diversity, as most protein-coding genes are spliced into multiple mRNA isoforms. However, errors in splicing patterns can give rise to mis-splicing with pathological consequences, such as the congenital diseases familial dysautonomia, …

An important class of intron retention events in human erythroblasts is regulated by cryptic exons proposed to function as splicing decoys.
RNA (New York, N.Y.) · 2018 · 24(9): 1255-1265
During terminal erythropoiesis, the splicing machinery in differentiating erythroblasts executes a robust intron retention (IR) program that impacts expression of hundreds of genes. We studied IR mechanisms in the <i>SF3B1</i> splicing factor gene, which expresses ∼50% of its transcripts in …

Biallelic mutations in the 3' exonuclease TOE1 cause pontocerebellar hypoplasia and uncover a role in snRNA processing.
Nature genetics · 2017 · 49(3): 457-464
Deadenylases are best known for degrading the poly(A) tail during mRNA decay. The deadenylase family has expanded throughout evolution and, in mammals, consists of 12 Mg<sup>2+</sup>-dependent 3'-end RNases with substrate specificity that is mostly unknown. Pontocerebellar hypoplasia type 7 (PCH7) …

ALS-causative mutations in FUS/TLS confer gain and loss of function by altered association with SMN and U1-snRNP.
Nature communications · 2015 · 6: 6171
The RNA-binding protein FUS/TLS, mutation in which is causative of the fatal motor neuron disease amyotrophic lateral sclerosis (ALS), is demonstrated to directly bind to the U1-snRNP and SMN complexes. ALS-causative mutations in FUS/TLS are shown to abnormally enhance their …
