Mechanoadaptation via Myosin Cytoplasmic Redistribution Protects Circulating Tumor Cells From Shear‐induced Death During Hematogenous Dissemination

Advanced Science, EarlyView.
This study investigates how CTCs survive varying shear stress during hematogenous metastasis. We uncover a self‐protection mechanism, by which non‐adherent CTCs adapt to high shearing milieu through accumulated cytoplasmic myosin‐mediated disruption of myosin‐actin binding, attenuating force transmission into chromatin to protect CTCs from shear ...

Brain and Liver Dual‐Targeting Oridonin Nanoparticles to Enhance Aβ Clearance for Alzheimer's Disease Therapy

Advanced Science, EarlyView.
We developed a nanoparticle named OAF, which simultaneously targeted to both the brain and liver via the transferrin receptor 1 (TfR1) receptor, promoting lipoprotein receptor‐related protein 1 (LRP1) expression to enhance amyloid‐beta (Aβ) clearance. In AD mice model, OAF significantly reduced Aβ deposition and cognitive impairment, while a mitigating

Tracking of [14C]Polystyrene Nanoplastics in Pregnant Mice

Advanced Science, EarlyView.
This study investigates [14C]polystyrene nanoplastic ([14C]PS) translocation in late‐stage pregnant mice after intranasal (0.5 mg of [14C]PS on GD12, GD14, and GD16, n = 6) and intravenous administration (1.5 mg of [14C]PS on GD16, n = 6). 14C‐radiolabel allows quantitative tracking of unmodified polystyrene nanoplastics.

Capillary Electrophoresis for Sampling Single Nerve Cells

CHIMIA, 1991
Two micro-capillary electrophoresis techniques are underdevelopment to acquire and determine catecholamines in single nerve cells. The first method involves the analysis of neurotransmitters in a portion of cytoplasm withdrawn from a single cell,

Affinity‐Based Interactome Mapping of Inositol Pyrophosphates Reveals 4/6‐PP‐InsP5‐Binding Proteins in Plants

Advanced Science, EarlyView.
ABSTRACT Inositol pyrophosphates (PP‐InsPs) are central regulators of eukaryotic signaling events. While certain PP‐InsP isomers have been conclusively linked to the regulation of phosphate homeostasis through interaction with SPX domain‐containing proteins in plants, the functions of the recently discovered isomer 4/6‐PP‐InsP5 remain largely unknown ...

A CLE11b‐CLE16 Signaling Relay Mediates Root‐Shoot‐Root Crosstalk for Drought Adaptation in Common Bean

Advanced Science, EarlyView.
A novel root‐shoot‐root signaling relay, mediated by CLE peptides, coordinates drought adaptation in common bean. Root‐derived PvCLE11b translocates acropetally to leaves, inducing PvCLE16 expression via PvTCP10. Leaf‐accumulated PvCLE16 triggers stomatal closure and translocates basipetally to modulate root architecture.

Plant‐Derived Melatonin Inhibits Bacterial Virulence via CpxA/R Two‐Component System

Advanced Science, EarlyView.
Plant‐derived melatonin is sensed by CpxAE48/T51, which inhibits the phosphorylation cascade transmission from CpxAH240 to CpxRD52, resulting in the inhibition of DNA‐binding capacity of CpxR and subsequent T3SS genes expression in Pst DC3000. ABSTRACT In defending against pathogens, plants deploy diverse secondary metabolites and signaling molecules ...
