Proton FLASH Exposure Preserves Gut Commensal Microbiomes and Spares Intestinal Stem Cells

open access: yesAdvanced Science, EarlyView.
This study highlights the role of Proton FLASH abdominal irradiation in sparing of intestinal stem cells and preservation of key gut microbial population resulting minimization of radiation toxicity in intestinal epithelium in mice. Our findings support the potential of Proton FLASH to improve the therapeutic ratio for abdominal radiation exposure ...

Beta-catenin Forms Protein Aggregation at High Concentrations in HEK293TCells

open access: yesIranian Journal of Medical Sciences, 2017
Background: The canonical Wnt signal transduction (or the Wnt/β-catenin pathway) plays a crucial role in the development of animals and in carcinogenesis. Beta-catenin is the central component of this signaling pathway.

Wearable Battery‐Free Electrotherapy of Smartsensors for Wound Healthcare

open access: yesAdvanced Science, EarlyView.
Herein, we propose a simple strategy for integrating battery‐free electrotherapy wound dressings with wound sensors. Solid‐state supercapacitors constructed by PMAB with cross‐linked interpenetrating network provide energy for electrotherapy. Meanwhile, excellent mechanical sensing performance of wound dressing was used for wound assessment.

Wnt/beta-catenin signaling controls development of the blood–brain barrier [PDF]

open access: yes, 2009
The blood–brain barrier (BBB) is confined to the endothelium of brain capillaries and is indispensable for fluid homeostasis and neuronal function. In this study, we show that endothelial Wnt/beta-catenin (beta-cat) signaling regulates induction and ...

SMAD4 Palmitoylation Drives a Metabolic‐Transcriptional Circuit to Promote Tumorigenesis and Confers Radiosensitivity in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies palmitoylation as a novel regulatory modification of SMAD4, mediated by ZDHHC22/APT2. It activates fatty acid synthesis, creating a self‐reinforcing SMAD4–FASN–palmitate feedback loop that drives pancreatic cancer growth and enhances radiotherapy sensitivity.

15,16-Dihydrotanshinone I, a novel β-catenin-targeting inhibitor that inhibits its nuclear translocation and reduces downstream CD36 expression in cancer

open access: yesJournal of Translational Medicine
Background Wnt/β-catenin signaling drives many cancers; however, current inhibition strategies have limitations. Direct β-catenin inhibitors that block nuclear translocation represent an alternative therapeutic approach.

Engineering β-catenin-derived peptides for α-catenin binding

open access: yesEmergent Materials
Abstract The complex formed by the β-catenin and α-catenin adaptor proteins acts as a molecular bridge that enables E-cadherin-based cell–cell adhesion assembly and maintenance in the epithelial tissue. This occurs through the interaction between the intracellular domain of E-cadherin and β-catenin on the one hand and between F-actin and α ...

Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

open access: yesAdvanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

Melanoma Development and Progression Are Associated with Rad6 Upregulation and β-Catenin Relocation to the Cell Membrane

open access: yesJournal of Skin Cancer, 2014
We have previously demonstrated that Rad6 and β-catenin enhance each other's expression through a positive feedback loop to promote breast cancer development/progression. While β-catenin has been implicated in melanoma pathogenesis, Rad6 function has not

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

open access: yesAdvanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome
