We establish a recycling chain reaction (RCR) using a single hairpin, H3, which disassembles HCR assemblies to unlock the inherent autocatalytic potential of HCR. Conventional HCR is redefined as the fully constrained state (H3 = 0) of RCR. Tuning H3 ratios enables dynamic control over DNA assembly, providing a compact platform for biomolecular ...

Inverse Diels‐Alder Cycloaddition Reaction was developed for ultrasensitive miR‐21 detection. Based on the enhanced Through‐Bond Energy Transfer and catalytic amplification, it shows a detection limit of 3.58 × 10−18 M and 100 aM–100 nM linear range. It enables high‐contrast cell/tissue imaging and distinguishes lung cancer patients in serum, promising

Abstract Ninety percent of all primary liver malignancies are hepatocellular carcinomas (HCC), making liver cancer the third most common cause of cancer‐associated mortality. Different patterns of programmed cell death (PCD) are crucial for the survival of tumors, and they might serve as a prognostic marker for HCC.

Rare‐earth ions act as multifunctional modifiers in perovskite solar cells by improving charge transport, suppressing oxygen vacancies, passivating defects, promoting grain growth, and enabling redox‐mediated stabilization. In addition, RE‐doped layers can expand spectral utilization through upconversion and downconversion, thereby enhancing light ...

Decreased Production of Tissue Plasminogen Activator in Endothelial Cells From Nasal Polyps
ABSTRACT Introduction Previous studies have demonstrated that chronic rhinosinusitis with nasal polyps (CRSwNP) is characterized by excessive fibrin deposition which is related to impaired production of tissue plasminogen activator(t‐PA) by epithelial cells.

Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

Koumine binds IGF2BP3 and promotes its proteasomal degradation, reducing m6A on EED mRNA, accelerating EED decay, lowering H3K27me3, and promoting IRF transcription, thereby restoring MHC‐I and enhancing CD8+ T cell killing. ABSTRACT Resistance to immune checkpoint blockade in gastric cancer often arises from defective antigen presentation due to MHC‐I

SLAMF6 recruits SHP‐2 to activate STAT1, upregulates CXCL10 and PD‐L1, promotes CD8+T cell infiltration, and enhances the efficacy of anti‐PD‐L1 therapy. ABSTRACT As a T‐cell receptor co‐stimulatory protein, signaling lymphocyte activation molecule family 6 (SLAMF6) is a member of the immune cell activating receptor family and is expressed on T cells ...

Spatial transcriptomic profiling of SCLC revealed marked intratumoral heterogeneity, including coexisting neuroendocrine and non‐neuroendocrine states and spatially heterogeneous hypoxia, and identified an MMP12+ macrophage population enriched at hypoxic and necrotic tumor interfaces.
