NAT10 promotes vascular remodelling via mRNA ac4C acetylation
Authors' conclusion
This study reveals that NAT10 promotes vascular remodelling via mRNA ac4C acetylation, which may be a promising therapeutic target against vascular remodelling.
Study context
- Population
- Injured human and rodent arteries; Vascular smooth muscle cell (VSMCs)
Methodological detailsin-vitro and in-vivo vascular injury models, RNA sequence (RNA-seq), acRIP-seq and RIP-seq
- In-vitro and in-vivo vascular injury models
- RNA-seq, acRIP-seq and RIP-seq
Main finding
As reported in the abstract
- NAT10 and ac4C modifications upregulated in injured human and rodent arteries
- VSMC NAT10 deletion reduced post-injury neointima formation and VSMC phenotype switching
- NAT10, by ac4C modification, directly interacts with mRNAs incl. ITGB1 and Col1a2
- NAT10-mediated ac4C increased ITGB1 mRNA stability and downstream focal adhesion kinase (FAK) signaling, influencing VSMC proliferation and vascular remodelling
- Remodelin (NAT10 inhibitor) prevented neointima formation by suppressing VSMC proliferation, downregulating ITGB1 and deactivating FAK signaling
