Snord15b Maintains Stemness of Intestinal Stem Cells via Enhancement of Alternative Splicing of Btrc Short Isoform for Suppression of β‐Catenin Ubiquitination

Advanced Science, EarlyView.
In intestinal stem cells (ISCs), Snord15b associates with Ilf2 to recruit splicing factors for alternative splicing of Btrc mRNA, leading to the generation of short Btrc. This short Btrc fails to form a functional E3 ubiquitin ligase complex for β‐catenin ubiquitination and degradation.

Interrogations of single-cell RNA splicing landscapes with SCASL define new cell identities with physiological relevance

Nature Communications
RNA splicing shapes the gene regulatory programs that underlie various physiological and disease processes. Here, we present the SCASL (single-cell clustering based on alternative splicing landscapes) method for interrogating the heterogeneity of RNA ...

Lactylation of HMGB1 at K177 Drives Nuclear Export of TIAR to Promote Hypoxia‐Induced Stress Granule Formation

Advanced Science, EarlyView.
This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

CircSMEK1 Suppresses HCC via the hnRNPK‐IGF2‐AKT Axis: A Diagnostic Biomarker and Therapeutic Target

Advanced Science, EarlyView.
CircSMEK1 is downregulated in MASH/HCC and predicts poor prognosis. It suppresses tumor progression by promoting hnRNPK ubiquitination and inhibiting the IGF2/PI3K/AKT axis, while its loss activates immunosuppressive cancer‐associated fibroblasts. Serum circSMEK1 serves as a non‐invasive diagnostic biomarker, and its restoration potently inhibits HCC ...

Preservation of ALYREF Phase Separation Mitigates Doxorubicin‐Induced Cardiomyocyte DNA Damage and Cardiotoxicity

Advanced Science, EarlyView.
Binding of Doxorubicin to ALYREF disrupts its phase‐separated condensate and induces DNA damage and apoptosis in cardiomyocytes Abstract The clinical utility of the anticancer agent doxorubicin (DOX) is limited by its dose‐dependent cardiotoxicity.

Therapeutic potential of alternative splicing in cardiovascular diseases

EBioMedicine
Summary: RNA splicing is an important RNA processing step required by multiexon protein-coding mRNAs and some noncoding RNAs. Precise RNA splicing is required for maintaining gene and cell function; however, mis-spliced RNA transcripts can lead to loss ...

Hypoxia‐Induced circPRELID2 Promotes Gastric Cancer Metastasis by Facilitating ZEB2 Translation via PCBP1 O‐GlcNAcylation

Advanced Science, EarlyView.
Under hypoxia, HIF1A is directly bound to the PRELID2 promoter to increase PRELID2 pre‐mRNA expression, followed by the DYRK1A–SFPQ–SAM68 complex binding to Alu‐containing introns in PRELID2 pre‐mRNA, leading to circPRELID2 circularization. CircPRELID2 interacts with PCBP1 and promotes its cytoplasmic retention.
