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.

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.

ADAR1 as a Placental Innate Immune Rheostat Sustaining the Homeostatic Balance of Intrinsic Interferon Response at the Maternal‐Fetal Interface

Advanced Science, EarlyView.
This study reveals that ADAR1, an RNA‐editing enzyme, fine‐tunes immune responses in the placenta by preventing the accumulation of immunogenic double‐stranded RNAs (dsRNAs) from interferon‐stimulated genes. The loss of ADAR1 in the placenta leads to excessive interferon signaling restricted to the junctional zone, disrupting placental development and ...

The proteasome lid triggers COP9 signalosome activity during the transition of Saccharomyces cerevisiae cells into quiescence. [PDF]

, 2019
The class of Cullin–RING E3 ligases (CRLs) selectively ubiquitinate a large portion of proteins targeted for proteolysis by the 26S proteasome. Before degradation, ubiquitin molecules are removed from their conjugated proteins by deubiquitinating enzymes,

BLOC1S1 Attenuates B. Melitensis 16M LPS‐Triggered Autophagy by Spatial Confinement of TDP‐43

Advanced Science, EarlyView.
This study explores how B. melitensis 16M LPS and BLOC1S1 regulate autophagy in goat spermatogonial stem cells. The 16M LPS is activating AMPK‐dependent autophagy, increasing LC3B‐II/I ratios and lysosomal genes, while Escherichia coli LPS shows no effect.

The 2'-5' RNA Ligase of Escherichia coli: Purification, Cloning, and Genomic Disruption [PDF]

, 1996
An RNA ligase previously detected in extracts of Escherichia coli is capable of joining Saccharomyces cerevisiae tRNA splicing intermediates in the absence of ATP to form a 2-5 phosphodiester linkage (Greer, C., Javor, B., and Abelson, J. (1983) Cell 33,

tRNA‐Derived Fragment tRF‐22 Promotes Immunosuppression by Inhibiting HnRNPAB Ubiquitination in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
tRF‐22 fosters an immunosuppressive and pro‐oncogenic tumor microenvironment in ESCC by stabilizing hnRNPAB against TRIM25‐mediated ubiquitination and enhancing TGFβ2 expression, which increases PMN‐MDSCs infiltration and suppresses CD8+ T cells. Targeting tRF‐22 or blocking TGFβ signalling improves anti‐PD1 response, offering a promising therapeutic ...

CLAE: A High‐Fidelity Nanopore Sequencing Strategy for Read‐Level Viral Variant Detection and Environmental RNA Virus Discovery

Advanced Science, EarlyView.
High‐fidelity Nanopore sequencing offers a cost‐effective, portable path to uncovering viral dark matter in complex environments—but suffers from severe read‐length bias, low throughput, and limited accuracy. This study traces these limitations to core biochemical barriers and introduces CLAE, a foundational high‐fidelity platform that enables accurate,

Disruption of NF‐κB‐Mediated Copper Homeostasis Sensitizes Breast Cancer to Cuproptosis

Advanced Science, EarlyView.
This study reveals a feedback mechanism regulating copper homeostasis, in which copper directly interacts with TAK1 to activate NF‐κB signaling, while NF‐κB transcriptionally suppresses copper transporter (CTR1) expression. These findings highlight a promising therapeutic strategy for breast cancer by combining NF‐κB inhibitors with copper chelators or

Post‐Translational Modifications of TOE3 Regulate Antiviral Defense in Tobacco

Advanced Science, EarlyView.
CK2αL phosphorylates TOE3 and enhances its stability, while FBXL1 promotes the ubiquitination‐degradation of TOE3 via the 26S proteasome. Compared to CK2αL‐phosphorylated TOE3, nonphosphorylated TOE3 shows a much higher affinity for FBXL1 and is more susceptible to ubiquitination‐degradation, thus facilitating viral infection. The regulatory mechanisms
