MZF1 Inhibits TGFβ‐1/SMAD Signaling by Transcriptionally Activating SnoN to Augment Tumorigenic Potential in Colon Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies MZF1 as a core regulator of colon cancer via SnoN‐mediated TGF‐β suppression, proposes 10Panx Acetate as a targeted inhibitor, and validates MZF1/SnoN as prognostic markers for aggressive disease. ABSTRACT Colon cancer progression is associated with transcriptional and signaling abnormalities.

Inorganic Nanomaterials can Promote or Inhibit Tumor Metastasis Depending on Tumor Microenvironment Composition

open access: yesAdvanced Science, EarlyView.
As engineered nanomaterials gain prominence in cancer imaging and therapy, understanding their impact on tumor progression becomes increasingly critical. We demonstrate that gold and silica‐coated gold nanomaterials can either suppress or enhance breast cancer metastasis through distinct tumor microenvironment interactions, while identifying ...

Effect of molecule size on cellular uptake.

open access: yes, 2013
From looking at A, it can be seen that as the Stokes radius increases, the amount of dextran taken up by the cell decreases. The protoplasts take up less dextrans than the intact cells for Stokes radii smaller than 5 = 30 cells with error bars ...

Nano Proton Scavengers Modulate Endosomal pH to Inhibit Microglial Activation and Enhance Stroke Recovery

open access: yesAdvanced Science, EarlyView.
Amphiphilic sulfonated chitosan nanoparticles buffer endo/lysosomal acidity in microglia by limiting V‐ATPase membrane recruitment and restoring endosomal homeostasis. Following systemic administration, they accumulate in the ischemic hemisphere partly through association with infiltrating immune cells, suppress TLR3/IRF3 and TLR4/NF‐κB signaling ...

FITC-dextrans as fluorescence and electron microscopic tracers in studies on capillary and cell permeability of the CNS.

open access: yes, 1980
FITC-dextrans can be detected at the ultrastructural level as round electron dense particles, with no sign of distortion or aggregation. Because this tracer is a stable, non-toxic polymer of biological origin obtainable in a wide range of molecular ...

Defect‐Engineered BiO2‐X Nanosheets Mediate Sono‐Thermomechanical ECM Remodeling for Hepatocellular Carcinoma Immunotherapy

open access: yesAdvanced Science, EarlyView.
Herein, an ultrasound‐responsive BiO2‐X/siFn1 nanoplatform is developed to overcome anti‐PD‐1 resistance in hepatocellular carcinoma. Upon ultrasound irradiation, the platform downregulates fibronectin expression, while its sonothermal effect softens the dense extracellular matrix and activates antitumor immunity in the tumor microenvironment, thereby ...

Altered glomerular permselectivity to neutral dextrans and heteroporous membrane modeling in human pregnancy

open access: yes, 1996
Hyperfiltration precedes renal function loss in several nephropathies. Animal studies suggest this may be due to accompanying increases in transglomerular capillary hydrostatic pressure difference (delta P) and/or altered glomerular processing of ...

Atmospheric Water Harvesting Through Polymer Hydrogel Sorbents: Materials Chemistry, Design Strategies, and Applications

open access: yesAdvanced Science, EarlyView.
Polymer‐based hydrogels have emerged as promising materials for atmospheric water harvesting (AWH) due to their high water affinity, tunable network structure, and excellent moisture adsorption‐desorption performance. Functional hydrogel systems enable efficient water capture and controlled release under low‐energy conditions, offering a sustainable ...

Effect of Dextrans on Cryopreservation of Goat Cauda Epididymal Spermatozoa using a Chemically Defined Medium

open access: yes, 2002
Experiments were carried out to investigate the cryoprotecting potential of dextrans (ranging from 10 to 2000 kDa) using a synthetic model system developed recently in this laboratory.
