Age‐Related Lamin B1 Deficiency Activates SLC7A11‐Dependent Disulfidptosis to Impair Osteogenesis via Intercepting Mitochondrial Fission

open access: yesAdvanced Science, EarlyView.
This study reveals that age‐related LMNB1 deficiency in mesenchymal stem cells epigenetically upregulates SLC7A11, triggering actin disulfidptosis and mitochondrial dysfunction. This cascade impairs bone formation in senile osteoporosis. Furthermore, researchers identified the FDA‐approved drug naldemedine as a targeted SLC7A11 inhibitor to reverse ...

Mechanical Signatures of Nucleic Acid Trefoil Knot Topology

open access: yesAngewandte Chemie, EarlyView.
Single‐stranded DNA can be designed with sequences that self‐thread into topological knots. The exact same sequence can alternatively be turned into an unknotted pseudoknot. The topology of the resulting polymer is determined by applying force with optical tweezers, causing the pseudoknot to resolve but the knot to tighten.

Bovine Viral Diarrhea Virus Testing Options

open access: yes, 2003
A review of bovine viral diarrhea virus (BVDV) dynamics is followed by a review of test efficiency measures. BVDV diagnostic challeneges are then discussed with attention to its pathogenesis during pregnancy and fetal effects.

NCLX Inhibition plus Ca2+ Delivery Potentiates Electroporation and Antitumor Immunity in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
Electroporation combined with NCLX inhibition and Ca2+ delivery induces mitochondrial Ca2+ overload in PDAC cells, triggering pyroptosis, DAMP release, and antitumor immune activation. Simultaneously, suppression of tumor‐derived SPP1 weakens SPP1–CD44 signaling and remodels macrophages toward an antitumor phenotype, thereby enhancing CD8+ T‐cell ...

dsRADAR: Imaging and Detecting Cellular dsRNA by Repurposing RNA‐Binding Proteins

open access: yesAngewandte Chemie, EarlyView.
Double‐stranded RNA (dsRNA) plays an important role in the innate immune system, but can be misregulated in disease, leading to inflammation. Despite the importance of this motif, methods for detecting dsRNA remain limited. This work shows that ADAR3 can be repurposed to provide improved detection of dsRNA, which is demonstrated in the context of viral

LncRNA FLJ20021 Restrains Fibroblast Senescence and Matrix Remodeling in Pelvic Organ Prolapse by Promoting XRCC6‐Dependent ADI1 Transcription

open access: yesAdvanced Science, EarlyView.
FLJ20021 interacts with XRCC6 to regulate ADI1 transcription and downstream cellular phenotypes in hUSLFs. Reduced FLJ20021 in POP is associated with lower ADI1, increased apoptosis, senescence, and an ECM‐degrading marker profile. Conversely, FLJ20021 overexpression enhances XRCC6‐dependent ADI1 expression, reduces apoptosis and senescence, and shifts

Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

open access: yesAdvanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...
