Peptide RL‐QN15 Regulates Functions of Epidermal Stem Cells to Accelerate Skin Wound Regeneration via the FZD8/β‐Catenin Axis

open access: yesExploration, EarlyView.
Amphibian‐derived peptide RL‐QN15 activates the Wnt/β‐catenin signaling pathway by interacting with the FZD8 membrane receptor, promoting epidermal stem cells proliferation, migration, stemness, and EMT processes, thus promoting skin wound healing.

Myosin II isoforms play distinct roles in adherens junction biogenesis

open access: yeseLife, 2019
Adherens junction (AJ) assembly under force is essential for many biological processes like epithelial monolayer bending, collective cell migration, cell extrusion and wound healing. The acto-myosin cytoskeleton acts as a major force-generator during the

Targeting Microbiome Metabolites: Reshaping Immunotherapy and Clinical Management Strategies for Colorectal Cancer

open access: yesiMetaMed, EarlyView.
The occurrence and progression of colorectal cancer are intricately linked to metabolites produced by the gut microbiota. Metabolites generated by pathogenic microbial communities can promote colorectal cancer development by reshaping the immune microenvironment.

Molecular components of the adherens junction

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2008
Adherens junctions serve to couple individual cells into various arrangements required for tissue structure and function. The central structural components of adherens junctions are transmembrane adhesion receptors, and their associated actin-binding/regulatory proteins.

Evaluation of Discoidin domain receptor 1 (DDR1) in junctional epithelial permeability and wound healing

open access: yesJournal of Periodontology, EarlyView.
Abstract Background Epithelium is the periodontal first line of defense against microbes. Discoidin domain receptor 1 (DDR1) is a collagen receptor expressed in epithelium. Ddr1 knockout (Ddr1−/−) mice develop periodontitis‐like defects, including junctional epithelium (JE) downgrowth, bacterial invasion, and alveolar bone loss.

Deep-brain stimulation associates with improved microvascular integrity in the subthalamic nucleus in Parkinson's disease

open access: yesNeurobiology of Disease, 2015
Deep brain stimulation (DBS) of the subthalamic nucleus (STN) has become an accepted treatment for motor symptoms in a subset of Parkinson's disease (PD) patients. The mechanisms why DBS is effective are incompletely understood, but previous studies show

Epigenetic Dysregulation of the NKX2‐1/SPDEF Axis Drives Persistent Goblet Cell Differentiation and Epithelial Barrier Dysfunction in Chronic Obstructive Pulmonary Disease

open access: yesRespirology, EarlyView.
This study investigated airway epithelial barrier dysfunction persistence in ex‐smokers with COPD and underlying mechanisms using single‐cell RNA and ATAC sequencing. Epigenetic NKX2‐1/SPDEF dysregulation maintains goblet cell hyperplasia and barrier dysfunction despite long‐term smoking cessation.

Transforming Growth Factor β/activin signalling induces epithelial cell flattening during Drosophila oogenesis

open access: yesBiology Open, 2015
Although the regulation of epithelial morphogenesis is essential for the formation of tissues and organs in multicellular organisms, little is known about how signalling pathways control cell shape changes in space and time.

Insights into the molecular mechanism of Sjogren's syndrome [PDF]

open access: yes, 2017
Sjogren’s syndrome (SS) is a chronic autoimmune disease, that affects primarily salivary and lacrimal glands, leading to increased morbidity. Recent studies indicate that loss of salivary gland function is associated with defective cell polarity ...

Brain Pericytes and Wnt/β‐Catenin Signaling Induce Functional Blood–Brain Barrier Phenotype in Human iPSC‐Derived Model

open access: yesSmall Methods, EarlyView.
This study shows that human iPSC‐derived endothelial cells acquire a functional blood–brain barrier phenotype when co‐cultured with brain pericytes and stimulated with CHIR‐99021, a Wnt/β‐catenin activator. This model recapitulates key barrier properties, inflammatory responses, and transcriptomic features of the native human BBB, offering new ...
