Carboranyl‐Curcuminoids for the Neutron Capture‐Based Treatment of Amyloid Aggregates in Alzheimer's Disease

Advanced Science, EarlyView.
The 10B‐enriched monocarbonyl analog of curcumin (BMAC) 10B‐9 enables site‐specific Boron Neutron Capture Therapy (BNCT) on amyloid‐β (Aβ) fibrils. Neutron irradiation induces histidine oxidation and fibril destabilization, as revealed by 1H‐NMR and FESEM analyses.

DNA Replication Errors Drive Genome‐Wide Small Inverted Triplication Dynamics

Advanced Science, EarlyView.
This study provides insight into the dynamic equilibrium mechanism of a novel structural variant, small inverted triplication (SIT), which is generated by misalignment of the 3’ flap generated under DNA replication stress with palindromic sequence. Alternatively, the end sequence may fold back on itself to form an inverted fragment.

DNA repair and gene targeting in plant end-joining mutants

, 2011
DNA double-strand breaks (DSBs) can be repaired by homologous recombination (HR) or by non-homologous end joining (NHEJ). The latter mechanism is the major route for DSB repair in the somatic cells of higher eukaryotes, including plants.

Epithelial TRIM27 Inhibits Intestinal Inflammation in Ulcerative Colitis by the USP7/TRIM27‐IKK Double Negative‐Feedback

Advanced Science, EarlyView.
ABSTRACT The E3 ubiquitin ligase tripartite motif 27 (TRIM27) is a negative regulator of NF‐κB activation and the innate immune response, and TRIM27 deficiency significantly impairs dextran sulfate sodium (DSS)‐induced colitis. The function of TRIM27 in intestinal epithelial cells (IECs), the mechanism by which TRIM27 inhibits the NF‐κB pathway and its

RBM10 Deficiency Promotes Anti‐PD‐1 Resistance in LUAD via STING Alternative Splicing‐Driven CCL7 Signaling and Macrophage Polarization

Advanced Science, EarlyView.
RBM10 deficiency promotes anti‐PD‐1 resistance in lung adenocarcinoma by altering STING alternative splicing, which enhances CCL7 secretion and CCR2‐dependent M2 macrophage polarization. A positive feedback loop via mitochondrial transfer sustains this immunosuppression.

Methylglyoxal Accumulation is Associated with Brain Inflammation after Myocardial Infarction with Sex and Regional Differences

Advanced Science, EarlyView.
This study identifies that methylglyoxal may play an important role in heart‐brain interactions after myocardial infarction. Myocardial infarction leads to increased levels of methylglyoxal‐derived advanced glycation end‐products (MG‐H1) in the brain of mice, which is associated with loss of blood‐brain barrier integrity and neuroinflammation ...

S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

Advanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...

Disruption of the SNRPF–DDX24–E2F4 Feedback Loop Uncouples Splicing and Transcriptional Regulation to Suppress Ovarian Cancer Progression

Advanced Science, EarlyView.
This study identifies SNRPF as a critical oncogenic driver in ovarian cancer. By regulating a self‐sustaining SNRPF–DDX24–E2F4 feedback loop through intron retention and nonsense‐mediated decay, SNRPF couples RNA splicing with transcriptional regulation to promote tumor progression.
