A dsRNA Viral Transcriptional Regulator Evades Innate Immunity by Hijacking Host CoTranscription Factor DHX9

Advanced Science, EarlyView.
This study identifies a new viral mechanism by a viral protein σ3 that functions as a vTR to suppress NF‐κB gene expression via its direct interaction with the host helicase DHX9. Through their interaction, σ3 not only impairs the initial recruitment of Pol II but also affects Pol II pause‐release and ultimately suppresses NF‐κB gene expression ...

Self‐Assembled Dictamni Cortex Nanoparticles Ameliorate Psoriasis by Epigenetic Modulation of HSP90AB1 and Suppression of the Inflammatory Response

Advanced Science, EarlyView.
This study develops self‐assembled Dictamni Cortex (BXP)‐Fe(III) infinite coordination polymer nanoparticles (NB) to improve BXP's solubility and bioavailability for psoriasis. NB transdermally treats psoriasis by targeting the epigenetic regulator CTCF (CCCTC‐binding factor), suppressing HSP90AB1 (heat shock protein 90 alpha family class B member 1 ...

ADA2 Forms Nuclear Condensates with GCN5 and ATP‐Citrate Lyase (ACL) to Modulate H3K9 Acetylation at Genes Functioning in Rice Meristems

Advanced Science, EarlyView.
This study unveils a novel GAA (GCN5‐ADA2‐ACL) complex that forms nuclear condensates to boost local acetyl‐CoA, facilitating histone acetylation and gene transcription in rice meristems. The research underscores the role of ADA2's disordered region in complex condensation and ACL's role in acetyl‐CoA production.
