Phase Separation of SF3B1 Serves as a Critical Post‐Transcriptional Regulator During Early Mouse Embryogenesis

Advanced Science, EarlyView.
Phase separation of SF3B1 acts as a key regulatory mechanism for dynamic alternative splicing throughout early mouse embryogenesis. Its absence triggers extensive splicing errors, which induce persistent DNA damage, defective cell cycle progression, and failed cell lineage commitment, and ultimately hinder the normal growth and development of ...

Prion‐Like Protein LENG8‐Mediated Nucleation Drives Stress Granule Assembly

Advanced Science, EarlyView.
LENG8 is a newly identified stress granule (SG) nucleator required for SG assembly. Following stress, nuclear LENG8 granules disassemble, allowing LENG8 to translocate into the cytoplasm and form independent nucleation foci. These foci fuse with canonical early G3BP1/TIA1 seeds via LENG8‐TIA1 binding to drive SG maturation.

An ATP‐Driven N Protein–DDX21 Molecular Switch Dynamically Controls SARS‐CoV‐2 RNA G‐Quadruplex Heterogeneity

Advanced Science, EarlyView.
An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

Endowing Flexibility of Alveolar Type II Cells to Recapitulate Development From Lung Bud to Alveoli

Advanced Science, EarlyView.
Adult human alveolar type 2 cells are chemically reprogrammed into expandable alveolar progenitor‐like cells that acquire bud tip‐like features during expansion and form organoids that mature into alveolar‐like structures. These organoids model influenza A virus infection and innate immune responses in vitro, while transplanted cells engraft ...

PTBP1‐Mediated Alternative Splicing of DNAJB6 Promotes Everolimus Resistance in Clear Cell Renal Cell Carcinoma via EIF4B/PKIB/AKT/mTOR Positive Feedback Loop

Advanced Science, EarlyView.
PTBP1‐mediated alternative splicing drives a pathogenic switch to the DNAJB6b isoform in everolimus‐resistant clear cell renal cell carcinoma. This splicing event programs a positive feedback loop including EIF4B/PKIB/AKT/mTOR, promoting aggressive therapy resistance.

Molecular Details of RNA Interactions With FUS Condensates Altering Assembly, Dynamics, and Aggregation

Angewandte Chemie, EarlyView.
Using NMR and molecular simulations, we map how RNA engages FUS LC‐RGG1 within condensates through electrostatic, π‐stacking, and polar contacts. These multivalent RNA contacts help stabilize RNA within FUS condensates while also reshaping condensate composition and dynamics.

NS1‐Induced PARP1 Phase Transitions Prolongs Host Transcriptional Pausing to Promote Influenza A Virus Replication

Advanced Science, EarlyView.
After IAV infection, NS1 induces PARP1 phase transition, reducing molecular mobility in condensates, prolonging host transcriptional pause, aiding RdRp cap snatching, and promoting viral transcription. ABSTRACT Influenza A virus (IAV) commandeers host transcriptional machinery to replicate, but mechanisms remain elusive.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...
